+What: legacy isochronous ABI of raw1394 (1st generation iso ABI)
+Date: June 2007 (scheduled), removed in kernel v2.6.23
+Contact: linux1394-devel@lists.sourceforge.net
+Description:
+ The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have
+ been deprecated for quite some time. They are very inefficient as they
+ come with high interrupt load and several layers of callbacks for each
+ packet. Because of these deficiencies, the video1394 and dv1394 drivers
+ and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created.
+
+Users:
+ libraw1394 users via the long deprecated API raw1394_iso_write,
+ raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv
+
+ libdc1394, which optionally uses these old libraw1394 calls
+ alternatively to the more efficient video1394 ABI

+
+ The Spidernet Device Driver
+ ===========================
+
+Written by Linas Vepstas <linas@austin.ibm.com>
+
+Version of 7 June 2007
+
+Abstract
+========
+This document sketches the structure of portions of the spidernet
+device driver in the Linux kernel tree. The spidernet is a gigabit
+ethernet device built into the Toshiba southbridge commonly used
+in the SONY Playstation 3 and the IBM QS20 Cell blade.
+
+The Structure of the RX Ring.
+=============================
+The receive (RX) ring is a circular linked list of RX descriptors,
+together with three pointers into the ring that are used to manage its
+contents.
+
+The elements of the ring are called "descriptors" or "descrs"; they
+describe the received data. This includes a pointer to a buffer
+containing the received data, the buffer size, and various status bits.
+
+There are three primary states that a descriptor can be in: "empty",
+"full" and "not-in-use". An "empty" or "ready" descriptor is ready
+to receive data from the hardware. A "full" descriptor has data in it,
+and is waiting to be emptied and processed by the OS. A "not-in-use"
+descriptor is neither empty or full; it is simply not ready. It may
+not even have a data buffer in it, or is otherwise unusable.
+
+During normal operation, on device startup, the OS (specifically, the
+spidernet device driver) allocates a set of RX descriptors and RX
+buffers. These are all marked "empty", ready to receive data. This
+ring is handed off to the hardware, which sequentially fills in the
+buffers, and marks them "full". The OS follows up, taking the full
+buffers, processing them, and re-marking them empty.
+
+This filling and emptying is managed by three pointers, the "head"
+and "tail" pointers, managed by the OS, and a hardware current
+descriptor pointer (GDACTDPA). The GDACTDPA points at the descr
+currently being filled. When this descr is filled, the hardware
+marks it full, and advances the GDACTDPA by one. Thus, when there is
+flowing RX traffic, every descr behind it should be marked "full",
+and everything in front of it should be "empty". If the hardware
+discovers that the current descr is not empty, it will signal an
+interrupt, and halt processing.
+
+The tail pointer tails or trails the hardware pointer. When the
+hardware is ahead, the tail pointer will be pointing at a "full"
+descr. The OS will process this descr, and then mark it "not-in-use",
+and advance the tail pointer. Thus, when there is flowing RX traffic,
+all of the descrs in front of the tail pointer should be "full", and
+all of those behind it should be "not-in-use". When RX traffic is not
+flowing, then the tail pointer can catch up to the hardware pointer.
+The OS will then note that the current tail is "empty", and halt
+processing.
+
+The head pointer (somewhat mis-named) follows after the tail pointer.
+When traffic is flowing, then the head pointer will be pointing at
+a "not-in-use" descr. The OS will perform various housekeeping duties
+on this descr. This includes allocating a new data buffer and
+dma-mapping it so as to make it visible to the hardware. The OS will
+then mark the descr as "empty", ready to receive data. Thus, when there
+is flowing RX traffic, everything in front of the head pointer should
+be "not-in-use", and everything behind it should be "empty". If no
+RX traffic is flowing, then the head pointer can catch up to the tail
+pointer, at which point the OS will notice that the head descr is
+"empty", and it will halt processing.
+
+Thus, in an idle system, the GDACTDPA, tail and head pointers will
+all be pointing at the same descr, which should be "empty". All of the
+other descrs in the ring should be "empty" as well.
+
+The show_rx_chain() routine will print out the the locations of the
+GDACTDPA, tail and head pointers. It will also summarize the contents
+of the ring, starting at the tail pointer, and listing the status
+of the descrs that follow.
+
+A typical example of the output, for a nearly idle system, might be
+
+net eth1: Total number of descrs=256
+net eth1: Chain tail located at descr=20
+net eth1: Chain head is at 20
+net eth1: HW curr desc (GDACTDPA) is at 21
+net eth1: Have 1 descrs with stat=x40800101
+net eth1: HW next desc (GDACNEXTDA) is at 22
+net eth1: Last 255 descrs with stat=xa0800000
+
+In the above, the hardware has filled in one descr, number 20. Both
+head and tail are pointing at 20, because it has not yet been emptied.
+Meanwhile, hw is pointing at 21, which is free.
+
+The "Have nnn decrs" refers to the descr starting at the tail: in this
+case, nnn=1 descr, starting at descr 20. The "Last nnn descrs" refers
+to all of the rest of the descrs, from the last status change. The "nnn"
+is a count of how many descrs have exactly the same status.
+
+The status x4... corresponds to "full" and status xa... corresponds
+to "empty". The actual value printed is RXCOMST_A.
+
+In the device driver source code, a different set of names are
+used for these same concepts, so that
+
+"empty" == SPIDER_NET_DESCR_CARDOWNED == 0xa
+"full" == SPIDER_NET_DESCR_FRAME_END == 0x4
+"not in use" == SPIDER_NET_DESCR_NOT_IN_USE == 0xf
+
+
+The RX RAM full bug/feature
+===========================
+
+As long as the OS can empty out the RX buffers at a rate faster than
+the hardware can fill them, there is no problem. If, for some reason,
+the OS fails to empty the RX ring fast enough, the hardware GDACTDPA
+pointer will catch up to the head, notice the not-empty condition,
+ad stop. However, RX packets may still continue arriving on the wire.
+The spidernet chip can save some limited number of these in local RAM.
+When this local ram fills up, the spider chip will issue an interrupt
+indicating this (GHIINT0STS will show ERRINT, and the GRMFLLINT bit
+will be set in GHIINT1STS). When the RX ram full condition occurs,
+a certain bug/feature is triggered that has to be specially handled.
+This section describes the special handling for this condition.
+
+When the OS finally has a chance to run, it will empty out the RX ring.
+In particular, it will clear the descriptor on which the hardware had
+stopped. However, once the hardware has decided that a certain
+descriptor is invalid, it will not restart at that descriptor; instead
+it will restart at the next descr. This potentially will lead to a
+deadlock condition, as the tail pointer will be pointing at this descr,
+which, from the OS point of view, is empty; the OS will be waiting for
+this descr to be filled. However, the hardware has skipped this descr,
+and is filling the next descrs. Since the OS doesn't see this, there
+is a potential deadlock, with the OS waiting for one descr to fill,
+while the hardware is waiting for a different set of descrs to become
+empty.
+
+A call to show_rx_chain() at this point indicates the nature of the
+problem. A typical print when the network is hung shows the following:
+
+net eth1: Spider RX RAM full, incoming packets might be discarded!
+net eth1: Total number of descrs=256
+net eth1: Chain tail located at descr=255
+net eth1: Chain head is at 255
+net eth1: HW curr desc (GDACTDPA) is at 0
+net eth1: Have 1 descrs with stat=xa0800000
+net eth1: HW next desc (GDACNEXTDA) is at 1
+net eth1: Have 127 descrs with stat=x40800101
+net eth1: Have 1 descrs with stat=x40800001
+net eth1: Have 126 descrs with stat=x40800101
+net eth1: Last 1 descrs with stat=xa0800000
+
+Both the tail and head pointers are pointing at descr 255, which is
+marked xa... which is "empty". Thus, from the OS point of view, there
+is nothing to be done. In particular, there is the implicit assumption
+that everything in front of the "empty" descr must surely also be empty,
+as explained in the last section. The OS is waiting for descr 255 to
+become non-empty, which, in this case, will never happen.
+
+The HW pointer is at descr 0. This descr is marked 0x4.. or "full".
+Since its already full, the hardware can do nothing more, and thus has
+halted processing. Notice that descrs 0 through 254 are all marked
+"full", while descr 254 and 255 are empty. (The "Last 1 descrs" is
+descr 254, since tail was at 255.) Thus, the system is deadlocked,
+and there can be no forward progress; the OS thinks there's nothing
+to do, and the hardware has nowhere to put incoming data.
+
+This bug/feature is worked around with the spider_net_resync_head_ptr()
+routine. When the driver receives RX interrupts, but an examination
+of the RX chain seems to show it is empty, then it is probable that
+the hardware has skipped a descr or two (sometimes dozens under heavy
+network conditions). The spider_net_resync_head_ptr() subroutine will
+search the ring for the next full descr, and the driver will resume
+operations there. Since this will leave "holes" in the ring, there
+is also a spider_net_resync_tail_ptr() that will skip over such holes.
+
+As of this writing, the spider_net_resync() strategy seems to work very
+well, even under heavy network loads.
+
+
+The TX ring
+===========
+The TX ring uses a low-watermark interrupt scheme to make sure that
+the TX queue is appropriately serviced for large packet sizes.
+
+For packet sizes greater than about 1KBytes, the kernel can fill
+the TX ring quicker than the device can drain it. Once the ring
+is full, the netdev is stopped. When there is room in the ring,
+the netdev needs to be reawakened, so that more TX packets are placed
+in the ring. The hardware can empty the ring about four times per jiffy,
+so its not appropriate to wait for the poll routine to refill, since
+the poll routine runs only once per jiffy. The low-watermark mechanism
+marks a descr about 1/4th of the way from the bottom of the queue, so
+that an interrupt is generated when the descr is processed. This
+interrupt wakes up the netdev, which can then refill the queue.
+For large packets, this mechanism generates a relatively small number
+of interrupts, about 1K/sec. For smaller packets, this will drop to zero
+interrupts, as the hardware can empty the queue faster than the kernel
+can fill it.

+Linux power supply class
+========================
+
+Synopsis
+~~~~~~~~
+Power supply class used to represent battery, UPS, AC or DC power supply
+properties to user-space.
+
+It defines core set of attributes, which should be applicable to (almost)
+every power supply out there. Attributes are available via sysfs and uevent
+interfaces.
+
+Each attribute has well defined meaning, up to unit of measure used. While
+the attributes provided are believed to be universally applicable to any
+power supply, specific monitoring hardware may not be able to provide them
+all, so any of them may be skipped.
+
+Power supply class is extensible, and allows to define drivers own attributes.
+The core attribute set is subject to the standard Linux evolution (i.e.
+if it will be found that some attribute is applicable to many power supply
+types or their drivers, it can be added to the core set).
+
+It also integrates with LED framework, for the purpose of providing
+typically expected feedback of battery charging/fully charged status and
+AC/USB power supply online status. (Note that specific details of the
+indication (including whether to use it at all) are fully controllable by
+user and/or specific machine defaults, per design principles of LED
+framework).
+
+
+Attributes/properties
+~~~~~~~~~~~~~~~~~~~~~
+Power supply class has predefined set of attributes, this eliminates code
+duplication across drivers. Power supply class insist on reusing its
+predefined attributes *and* their units.
+
+So, userspace gets predictable set of attributes and their units for any
+kind of power supply, and can process/present them to a user in consistent
+manner. Results for different power supplies and machines are also directly
+comparable.
+
+See drivers/power/ds2760_battery.c and drivers/power/pda_power.c for the
+example how to declare and handle attributes.
+
+
+Units
+~~~~~
+Quoting include/linux/power_supply.h:
+
+ All voltages, currents, charges, energies, time and temperatures in µV,
+ µA, µAh, µWh, seconds and tenths of degree Celsius unless otherwise
+ stated. It's driver's job to convert its raw values to units in which
+ this class operates.
+
+
+Attributes/properties detailed
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+~ ~ ~ ~ ~ ~ ~ Charge/Energy/Capacity - how to not confuse ~ ~ ~ ~ ~ ~ ~
+~ ~
+~ Because both "charge" (µAh) and "energy" (µWh) represents "capacity" ~
+~ of battery, this class distinguish these terms. Don't mix them! ~
+~ ~
+~ CHARGE_* attributes represents capacity in µAh only. ~
+~ ENERGY_* attributes represents capacity in µWh only. ~
+~ CAPACITY attribute represents capacity in *percents*, from 0 to 100. ~
+~ ~
+~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
+
+Postfixes:
+_AVG - *hardware* averaged value, use it if your hardware is really able to
+report averaged values.
+_NOW - momentary/instantaneous values.
+
+STATUS - this attribute represents operating status (charging, full,
+discharging (i.e. powering a load), etc.). This corresponds to
+BATTERY_STATUS_* values, as defined in battery.h.
+
+HEALTH - represents health of the battery, values corresponds to
+POWER_SUPPLY_HEALTH_*, defined in battery.h.
+
+VOLTAGE_MAX_DESIGN, VOLTAGE_MIN_DESIGN - design values for maximal and
+minimal power supply voltages. Maximal/minimal means values of voltages
+when battery considered "full"/"empty" at normal conditions. Yes, there is
+no direct relation between voltage and battery capacity, but some dumb
+batteries use voltage for very approximated calculation of capacity.
+Battery driver also can use this attribute just to inform userspace
+about maximal and minimal voltage thresholds of a given battery.
+
+CHARGE_FULL_DESIGN, CHARGE_EMPTY_DESIGN - design charge values, when
+battery considered full/empty.
+
+ENERGY_FULL_DESIGN, ENERGY_EMPTY_DESIGN - same as above but for energy.
+
+CHARGE_FULL, CHARGE_EMPTY - These attributes means "last remembered value
+of charge when battery became full/empty". It also could mean "value of
+charge when battery considered full/empty at given conditions (temperature,
+age)". I.e. these attributes represents real thresholds, not design values.
+
+ENERGY_FULL, ENERGY_EMPTY - same as above but for energy.
+
+CAPACITY - capacity in percents.
+CAPACITY_LEVEL - capacity level. This corresponds to
+POWER_SUPPLY_CAPACITY_LEVEL_*.
+
+TEMP - temperature of the power supply.
+TEMP_AMBIENT - ambient temperature.
+
+TIME_TO_EMPTY - seconds left for battery to be considered empty (i.e.
+while battery powers a load)
+TIME_TO_FULL - seconds left for battery to be considered full (i.e.
+while battery is charging)
+
+
+Battery <-> external power supply interaction
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Often power supplies are acting as supplies and supplicants at the same
+time. Batteries are good example. So, batteries usually care if they're
+externally powered or not.
+
+For that case, power supply class implements notification mechanism for
+batteries.
+
+External power supply (AC) lists supplicants (batteries) names in
+"supplied_to" struct member, and each power_supply_changed() call
+issued by external power supply will notify supplicants via
+external_power_changed callback.
+
+
+QA
+~~
+Q: Where is POWER_SUPPLY_PROP_XYZ attribute?
+A: If you cannot find attribute suitable for your driver needs, feel free
+ to add it and send patch along with your driver.
+
+ The attributes available currently are the ones currently provided by the
+ drivers written.
+
+ Good candidates to add in future: model/part#, cycle_time, manufacturer,
+ etc.
+
+
+Q: I have some very specific attribute (e.g. battery color), should I add
+ this attribute to standard ones?
+A: Most likely, no. Such attribute can be placed in the driver itself, if
+ it is useful. Of course, if the attribute in question applicable to
+ large set of batteries, provided by many drivers, and/or comes from
+ some general battery specification/standard, it may be a candidate to
+ be added to the core attribute set.
+
+
+Q: Suppose, my battery monitoring chip/firmware does not provides capacity
+ in percents, but provides charge_{now,full,empty}. Should I calculate
+ percentage capacity manually, inside the driver, and register CAPACITY
+ attribute? The same question about time_to_empty/time_to_full.
+A: Most likely, no. This class is designed to export properties which are
+ directly measurable by the specific hardware available.
+
+ Inferring not available properties using some heuristics or mathematical
+ model is not subject of work for a battery driver. Such functionality
+ should be factored out, and in fact, apm_power, the driver to serve
+ legacy APM API on top of power supply class, uses a simple heuristic of
+ approximating remaining battery capacity based on its charge, current,
+ voltage and so on. But full-fledged battery model is likely not subject
+ for kernel at all, as it would require floating point calculation to deal
+ with things like differential equations and Kalman filters. This is
+ better be handled by batteryd/libbattery, yet to be written.
--- /dev/null
+
+This is the CFS scheduler.
+
+80% of CFS's design can be summed up in a single sentence: CFS basically
+models an "ideal, precise multi-tasking CPU" on real hardware.
+
+"Ideal multi-tasking CPU" is a (non-existent :-)) CPU that has 100%
+physical power and which can run each task at precise equal speed, in
+parallel, each at 1/nr_running speed. For example: if there are 2 tasks
+running then it runs each at 50% physical power - totally in parallel.
+
+On real hardware, we can run only a single task at once, so while that
+one task runs, the other tasks that are waiting for the CPU are at a
+disadvantage - the current task gets an unfair amount of CPU time. In
+CFS this fairness imbalance is expressed and tracked via the per-task
+p->wait_runtime (nanosec-unit) value. "wait_runtime" is the amount of
+time the task should now run on the CPU for it to become completely fair
+and balanced.
+
+( small detail: on 'ideal' hardware, the p->wait_runtime value would
+ always be zero - no task would ever get 'out of balance' from the
+ 'ideal' share of CPU time. )
+
+CFS's task picking logic is based on this p->wait_runtime value and it
+is thus very simple: it always tries to run the task with the largest
+p->wait_runtime value. In other words, CFS tries to run the task with
+the 'gravest need' for more CPU time. So CFS always tries to split up
+CPU time between runnable tasks as close to 'ideal multitasking
+hardware' as possible.
+
+Most of the rest of CFS's design just falls out of this really simple
+concept, with a few add-on embellishments like nice levels,
+multiprocessing and various algorithm variants to recognize sleepers.
+
+In practice it works like this: the system runs a task a bit, and when
+the task schedules (or a scheduler tick happens) the task's CPU usage is
+'accounted for': the (small) time it just spent using the physical CPU
+is deducted from p->wait_runtime. [minus the 'fair share' it would have
+gotten anyway]. Once p->wait_runtime gets low enough so that another
+task becomes the 'leftmost task' of the time-ordered rbtree it maintains
+(plus a small amount of 'granularity' distance relative to the leftmost
+task so that we do not over-schedule tasks and trash the cache) then the
+new leftmost task is picked and the current task is preempted.
+
+The rq->fair_clock value tracks the 'CPU time a runnable task would have
+fairly gotten, had it been runnable during that time'. So by using
+rq->fair_clock values we can accurately timestamp and measure the
+'expected CPU time' a task should have gotten. All runnable tasks are
+sorted in the rbtree by the "rq->fair_clock - p->wait_runtime" key, and
+CFS picks the 'leftmost' task and sticks to it. As the system progresses
+forwards, newly woken tasks are put into the tree more and more to the
+right - slowly but surely giving a chance for every task to become the
+'leftmost task' and thus get on the CPU within a deterministic amount of
+time.
+
+Some implementation details:
+
+ - the introduction of Scheduling Classes: an extensible hierarchy of
+ scheduler modules. These modules encapsulate scheduling policy
+ details and are handled by the scheduler core without the core
+ code assuming about them too much.
+
+ - sched_fair.c implements the 'CFS desktop scheduler': it is a
+ replacement for the vanilla scheduler's SCHED_OTHER interactivity
+ code.
+
+ I'd like to give credit to Con Kolivas for the general approach here:
+ he has proven via RSDL/SD that 'fair scheduling' is possible and that
+ it results in better desktop scheduling. Kudos Con!
+
+ The CFS patch uses a completely different approach and implementation
+ from RSDL/SD. My goal was to make CFS's interactivity quality exceed
+ that of RSDL/SD, which is a high standard to meet :-) Testing
+ feedback is welcome to decide this one way or another. [ and, in any
+ case, all of SD's logic could be added via a kernel/sched_sd.c module
+ as well, if Con is interested in such an approach. ]
+
+ CFS's design is quite radical: it does not use runqueues, it uses a
+ time-ordered rbtree to build a 'timeline' of future task execution,
+ and thus has no 'array switch' artifacts (by which both the vanilla
+ scheduler and RSDL/SD are affected).
+
+ CFS uses nanosecond granularity accounting and does not rely on any
+ jiffies or other HZ detail. Thus the CFS scheduler has no notion of
+ 'timeslices' and has no heuristics whatsoever. There is only one
+ central tunable:
+
+ /proc/sys/kernel/sched_granularity_ns
+
+ which can be used to tune the scheduler from 'desktop' (low
+ latencies) to 'server' (good batching) workloads. It defaults to a
+ setting suitable for desktop workloads. SCHED_BATCH is handled by the
+ CFS scheduler module too.
+
+ Due to its design, the CFS scheduler is not prone to any of the
+ 'attacks' that exist today against the heuristics of the stock
+ scheduler: fiftyp.c, thud.c, chew.c, ring-test.c, massive_intr.c all
+ work fine and do not impact interactivity and produce the expected
+ behavior.
+
+ the CFS scheduler has a much stronger handling of nice levels and
+ SCHED_BATCH: both types of workloads should be isolated much more
+ agressively than under the vanilla scheduler.
+
+ ( another detail: due to nanosec accounting and timeline sorting,
+ sched_yield() support is very simple under CFS, and in fact under
+ CFS sched_yield() behaves much better than under any other
+ scheduler i have tested so far. )
+
+ - sched_rt.c implements SCHED_FIFO and SCHED_RR semantics, in a simpler
+ way than the vanilla scheduler does. It uses 100 runqueues (for all
+ 100 RT priority levels, instead of 140 in the vanilla scheduler)
+ and it needs no expired array.
+
+ - reworked/sanitized SMP load-balancing: the runqueue-walking
+ assumptions are gone from the load-balancing code now, and
+ iterators of the scheduling modules are used. The balancing code got
+ quite a bit simpler as a result.

- This enables support for the Atari ACSI interface. The driver
- supports hard disks and CD-ROMs, which have 512-byte sectors, or can
- be switched to that mode. Due to the ACSI command format, only disks
- up to 1 GB are supported. Special support for certain ACSI to SCSI
- adapters, which could relax that, isn't included yet. The ACSI
- driver is also the basis for certain other drivers for devices
- attached to the ACSI bus: Atari SLM laser printer, BioNet-100
- Ethernet, and PAMsNet Ethernet. If you want to use one of these
- devices, you need ACSI support, too.
-
- To compile this driver as a module, choose M here: the
- module will be called acsi.

- * Still to in this file:
- * - If a command ends with an error status (!= 0), the following
- * REQUEST SENSE commands (4 to fill the ST-DMA FIFO) are done by
- * polling the _IRQ signal (not interrupt-driven). This should be
- * avoided in future because it takes up a non-neglectible time in
- * the interrupt service routine while interrupts are disabled.
- * Maybe a timer interrupt will get lost :-(
- */
-
-/*
- * General notes:
- *
- * - All ACSI devices (disks, CD-ROMs, ...) use major number 28.
- * Minors are organized like it is with SCSI: The upper 4 bits
- * identify the device, the lower 4 bits the partition.
- * The device numbers (the upper 4 bits) are given in the same
- * order as the devices are found on the bus.
- * - Up to 8 LUNs are supported for each target (if CONFIG_ACSI_MULTI_LUN
- * is defined), but only a total of 16 devices (due to minor
- * numbers...). Note that Atari allows only a maximum of 4 targets
- * (i.e. controllers, not devices) on the ACSI bus!
- * - A optimizing scheme similar to SCSI scatter-gather is implemented.
- * - Removable media are supported. After a medium change to device
- * is reinitialized (partition check etc.). Also, if the device
- * knows the PREVENT/ALLOW MEDIUM REMOVAL command, the door should
- * be locked and unlocked when mounting the first or unmounting the
- * last filesystem on the device. The code is untested, because I
- * don't have a removable hard disk.

- here, otherwise N. Read the CD-ROM-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- Note that the answer to this question doesn't directly affect the
- kernel: saying N will just cause the configurator to skip all
- the questions about these CD-ROM drives. If you are unsure what you
- have, say Y and find out whether you have one of the following
- drives.
-
- For each of these drivers, a <file:Documentation/cdrom/{driver_name}>
- exists. Especially in cases where you do not know exactly which kind
- of drive you have you should read there. Most of these drivers use a
- file drivers/cdrom/{driver_name}.h where you can define your
- interface parameters and switch some internal goodies.
-
- To compile these CD-ROM drivers as a module, choose M instead of Y.
-
- If you want to use any of these CD-ROM drivers, you also have to
- answer Y or M to "ISO 9660 CD-ROM file system support" below (this
- answer will get "defaulted" for you if you enable any of the Linux
- CD-ROM drivers).

- CD-3110, Okano or Wearnes CDD110, Conrad TXC, or CyCD-ROM CR520 or
- CR540 CD-ROM drive. This driver -- just like all these CD-ROM
- drivers -- is NOT for CD-ROM drives with IDE/ATAPI interfaces, such
- as Aztech CDA269-031SE. Please read the file
- <file:Documentation/cdrom/aztcd>.
-
- If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM

-
- To compile this driver as a module, choose M here: the

-
- If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM

- Sound Blaster interface. Please read the file
- <file:Documentation/cdrom/sbpcd>.
-
- The Matsushita CR-521, CR-522, CR-523, CR-562, CR-563 drives
- (sometimes labeled "Creative"), the Creative Labs CD200, the
- Longshine LCS-7260, the "IBM External ISA CD-ROM" (in fact a CR-56x
- model), the TEAC CD-55A fall under this category. Some other
- "electrically compatible" drives (Vertos, Genoa, some Funai models)
- are currently not supported; for the Sanyo H94A drive currently a
- separate driver (asked later) is responsible. Most drives have a
- uniquely shaped faceplate, with a caddyless motorized drawer, but
- without external brand markings. The older CR-52x drives have a
- caddy and manual loading/eject, but still no external markings. The
- driver is able to do an extended auto-probing for interface
- addresses and drive types; this can help to find facts in cases you
- are not sure, but can consume some time during the boot process if
- none of the supported drives gets found. Once your drive got found,
- you should enter the reported parameters into
- <file:drivers/cdrom/sbpcd.h> and set "DISTRIBUTION 0" there.
-
- This driver can support up to four CD-ROM controller cards, and each
- card can support up to four CD-ROM drives; if you say Y here, you
- will be asked how many controller cards you have. If compiled as a
- module, only one controller card (but with up to four drives) is
- usable.
-
- If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM

-
- If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM

- HISTORY
- V0.0 Adaption to Aztech CD268-01A Version 1.3
- Version is PRE_ALPHA, unresolved points:
- 1. I use busy wait instead of timer wait in STEN_LOW,DTEN_LOW
- thus driver causes CPU overhead and is very slow
- 2. could not find a way to stop the drive, when it is
- in data read mode, therefore I had to set
- msf.end.min/sec/frame to 0:0:1 (in azt_poll); so only one
- frame can be read in sequence, this is also the reason for
- 3. getting 'timeout in state 4' messages, but nevertheless
- it works
- W.Zimmermann, Oct. 31, 1994
- V0.1 Version is ALPHA, problems #2 and #3 resolved.
- W.Zimmermann, Nov. 3, 1994
- V0.2 Modification to some comments, debugging aids for partial test
- with Borland C under DOS eliminated. Timer interrupt wait
- STEN_LOW_WAIT additionally to busy wait for STEN_LOW implemented;
- use it only for the 'slow' commands (ACMD_GET_Q_CHANNEL, ACMD_
- SEEK_TO_LEAD_IN), all other commands are so 'fast', that busy
- waiting seems better to me than interrupt rescheduling.
- Besides that, when used in the wrong place, STEN_LOW_WAIT causes
- kernel panic.
- In function aztPlay command ACMD_PLAY_AUDIO added, should make
- audio functions work. The Aztech drive needs different commands
- to read data tracks and play audio tracks.
- W.Zimmermann, Nov. 8, 1994
- V0.3 Recognition of missing drive during boot up improved (speeded up).
- W.Zimmermann, Nov. 13, 1994
- V0.35 Rewrote the control mechanism in azt_poll (formerly mcd_poll)
- including removal of all 'goto' commands. :-);
- J. Nardone, Nov. 14, 1994
- V0.4 Renamed variables and constants to 'azt' instead of 'mcd'; had
- to make some "compatibility" defines in azt.h; please note,
- that the source file was renamed to azt.c, the include file to
- azt.h
- Speeded up drive recognition during init (will be a little bit
- slower than before if no drive is installed!); suggested by
- Robby Schirmer.
- read_count declared volatile and set to AZT_BUF_SIZ to make
- drive faster (now 300kB/sec, was 60kB/sec before, measured
- by 'time dd if=/dev/cdrom of=/dev/null bs=2048 count=4096';
- different AZT_BUF_SIZes were test, above 16 no further im-
- provement seems to be possible; suggested by E.Moenkeberg.
- W.Zimmermann, Nov. 18, 1994
- V0.42 Included getAztStatus command in GetQChannelInfo() to allow
- reading Q-channel info on audio disks, if drive is stopped,
- and some other bug fixes in the audio stuff, suggested by
- Robby Schirmer.
- Added more ioctls (reading data in mode 1 and mode 2).
- Completely removed the old azt_poll() routine.
- Detection of ORCHID CDS-3110 in aztcd_init implemented.
- Additional debugging aids (see the readme file).
- W.Zimmermann, Dec. 9, 1994
- V0.50 Autodetection of drives implemented.
- W.Zimmermann, Dec. 12, 1994
- V0.52 Prepared for including in the standard kernel, renamed most
- variables to contain 'azt', included autoconf.h
- W.Zimmermann, Dec. 16, 1994
- V0.6 Version for being included in the standard Linux kernel.
- Renamed source and header file to aztcd.c and aztcd.h
- W.Zimmermann, Dec. 24, 1994
- V0.7 Changed VERIFY_READ to VERIFY_WRITE in aztcd_ioctl, case
- CDROMREADMODE1 and CDROMREADMODE2; bug fix in the ioctl,
- which causes kernel crashes when playing audio, changed
- include-files (config.h instead of autoconf.h, removed
- delay.h)
- W.Zimmermann, Jan. 8, 1995
- V0.72 Some more modifications for adaption to the standard kernel.
- W.Zimmermann, Jan. 16, 1995
- V0.80 aztcd is now part of the standard kernel since version 1.1.83.
- Modified the SET_TIMER and CLEAR_TIMER macros to comply with
- the new timer scheme.
- W.Zimmermann, Jan. 21, 1995
- V0.90 Included CDROMVOLCTRL, but with my Aztech drive I can only turn
- the channels on and off. If it works better with your drive,
- please mail me. Also implemented ACMD_CLOSE for CDROMSTART.
- W.Zimmermann, Jan. 24, 1995
- V1.00 Implemented close and lock tray commands. Patches supplied by
- Frank Racis
- Added support for loadable MODULEs, so aztcd can now also be
- loaded by insmod and removed by rmmod during run time
- Werner Zimmermann, Mar. 24, 95
- V1.10 Implemented soundcard configuration for Orchid CDS-3110 drives
- connected to Soundwave32 cards. Release for LST 2.1.
- (still experimental)
- Werner Zimmermann, May 8, 95
- V1.20 Implemented limited support for DOSEMU0.60's cdrom.c. Now it works, but
- sometimes DOSEMU may hang for 30 seconds or so. A fully functional ver-
- sion needs an update of Dosemu0.60's cdrom.c, which will come with the
- next revision of Dosemu.
- Also Soundwave32 support now works.
- Werner Zimmermann, May 22, 95
- V1.30 Auto-eject feature. Inspired by Franc Racis (racis@psu.edu)
- Werner Zimmermann, July 4, 95
- V1.40 Started multisession support. Implementation copied from mcdx.c
- by Heiko Schlittermann. Not tested yet.
- Werner Zimmermann, July 15, 95
- V1.50 Implementation of ioctl CDROMRESET, continued multisession, began
- XA, but still untested. Heavy modifications to drive status de-
- tection.
- Werner Zimmermann, July 25, 95
- V1.60 XA support now should work. Speeded up drive recognition in cases,
- where no drive is installed.
- Werner Zimmermann, August 8, 1995
- V1.70 Multisession support now is completed, but there is still not
- enough testing done. If you can test it, please contact me. For
- details please read Documentation/cdrom/aztcd
- Werner Zimmermann, August 19, 1995
- V1.80 Modification to suit the new kernel boot procedure introduced
- with kernel 1.3.33. Will definitely not work with older kernels.
- Programming done by Linus himself.
- Werner Zimmermann, October 11, 1995
- V1.90 Support for Conrad TXC drives, thank's to Jochen Kunz and Olaf Kaluza.
- Werner Zimmermann, October 21, 1995
- V2.00 Changed #include "blk.h" to <linux/blk.h> as the directory
- structure was changed. README.aztcd is now /usr/src/docu-
- mentation/cdrom/aztcd
- Werner Zimmermann, November 10, 95
- V2.10 Started to modify azt_poll to prevent reading beyond end of
- tracks.
- Werner Zimmermann, December 3, 95
- V2.20 Changed some comments
- Werner Zimmermann, April 1, 96
- V2.30 Implemented support for CyCDROM CR520, CR940, Code for CR520
- delivered by H.Berger with preworks by E.Moenkeberg.
- Werner Zimmermann, April 29, 96
- V2.40 Reorganized the placement of functions in the source code file
- to reflect the layered approach; did not actually change code
- Werner Zimmermann, May 1, 96
- V2.50 Heiko Eissfeldt suggested to remove some VERIFY_READs in
- aztcd_ioctl; check_aztcd_media_change modified
- Werner Zimmermann, May 16, 96
- V2.60 Implemented Auto-Probing; made changes for kernel's 2.1.xx blocksize
- Adaption to linux kernel > 2.1.0
- Werner Zimmermann, Nov 29, 97
-
- November 1999 -- Make kernel-parameter implementation work with 2.3.x
- Removed init_module & cleanup_module in favor of
- module_init & module_exit.
- Torben Mathiasen <tmm@image.dk>

/* Unfortunately, per device settings are not implemented through

-/*
-* Sony CDU-31A CDROM interface device driver.
-*
-* Corey Minyard (minyard@wf-rch.cirr.com)
-*
-* Colossians 3:17
-*
-* See Documentation/cdrom/cdu31a for additional details about this driver.
-*
-* The Sony interface device driver handles Sony interface CDROM
-* drives and provides a complete block-level interface as well as an
-* ioctl() interface compatible with the Sun (as specified in
-* include/linux/cdrom.h). With this interface, CDROMs can be
-* accessed and standard audio CDs can be played back normally.
-*
-* WARNING - All autoprobes have been removed from the driver.
-* You MUST configure the CDU31A via a LILO config
-* at boot time or in lilo.conf. I have the
-* following in my lilo.conf:
-*
-* append="cdu31a=0x1f88,0,PAS"
-*
-* The first number is the I/O base address of the
-* card. The second is the interrupt (0 means none).
- * The third should be "PAS" if on a Pro-Audio
- * spectrum, or nothing if on something else.
- *
- * This interface is (unfortunately) a polled interface. This is
- * because most Sony interfaces are set up with DMA and interrupts
- * disables. Some (like mine) do not even have the capability to
- * handle interrupts or DMA. For this reason you will see a lot of
- * the following:
- *
- * retry_count = jiffies+ SONY_JIFFIES_TIMEOUT;
- * while (time_before(jiffies, retry_count) && (! <some condition to wait for))
- * {
- * while (handle_sony_cd_attention())
- * ;
- *
- * sony_sleep();
- * }
- * if (the condition not met)
- * {
- * return an error;
- * }
- *
- * This ugly hack waits for something to happen, sleeping a little
- * between every try. it also handles attentions, which are
- * asynchronous events from the drive informing the driver that a disk
- * has been inserted, removed, etc.
- *
- * NEWS FLASH - The driver now supports interrupts but they are
- * turned off by default. Use of interrupts is highly encouraged, it
- * cuts CPU usage down to a reasonable level. I had DMA in for a while
- * but PC DMA is just too slow. Better to just insb() it.
- *
- * One thing about these drives: They talk in MSF (Minute Second Frame) format.
- * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
- * disk. The funny thing is that these are sent to the drive in BCD, but the
- * interface wants to see them in decimal. A lot of conversion goes on.
- *
- * DRIVER SPECIAL FEATURES
- * -----------------------
- *
- * This section describes features beyond the normal audio and CD-ROM
- * functions of the drive.
- *
- * XA compatibility
- *
- * The driver should support XA disks for both the CDU31A and CDU33A.
- * It does this transparently, the using program doesn't need to set it.
- *
- * Multi-Session
- *
- * A multi-session disk looks just like a normal disk to the user.
- * Just mount one normally, and all the data should be there.
- * A special thanks to Koen for help with this!
- *
- * Raw sector I/O
- *
- * Using the CDROMREADAUDIO it is possible to read raw audio and data
- * tracks. Both operations return 2352 bytes per sector. On the data
- * tracks, the first 12 bytes is not returned by the drive and the value
- * of that data is indeterminate.

- * CDs with form1 and form2 sectors cause problems
- * with current read-ahead strategy.
- *
- * Credits:
- * Heiko Eissfeldt <heiko@colossus.escape.de>
- * For finding abug in the return of the track numbers.
- * TOC processing redone for proper multisession support.
- *
- *
- * It probably a little late to be adding a history, but I guess I
- * will start.
- *
- * 10/24/95 - Added support for disabling the eject button when the
- * drive is open. Note that there is a small problem
- * still here, if the eject button is pushed while the
- * drive light is flashing, the drive will return a bad
- * status and be reset. It recovers, though.
- *
- * 03/07/97 - Fixed a problem with timers.
- *
- *
- * 18 Spetember 1997 -- Ported to Uniform CD-ROM driver by
- * Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- * changes by Erik Andersen <andersee@debian.org>
- *
- * 24 January 1998 -- Removed the scd_disc_status() function, which was now
- * just dead code left over from the port.
- * Erik Andersen <andersee@debian.org>
- *
- * 16 July 1998 -- Drive donated to Erik Andersen by John Kodis
- * <kodis@jagunet.com>. Work begun on fixing driver to
- * work under 2.1.X. Added temporary extra printks
- * which seem to slow it down enough to work.
- *
- * 9 November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>
- *
- * 22 October 2004 -- Make the driver work in 2.6.X
- * Added workaround to fix hard lockups on eject
- * Fixed door locking problem after mounting empty drive
- * Set double-speed drives to double speed by default
- * Removed all readahead things - not needed anymore
- * Ondrej Zary <rainbow@rainbow-software.org>

-
-History:
- Started 25 jan 1994. Waiting for documentation...
- 22 feb 1995: 0.1a first reasonably safe polling driver.
- Two major bugs, one in read_sector and one in
- do_cm206_request, happened to cancel!
- 25 feb 1995: 0.2a first reasonable interrupt driven version of above.
- uart writes are still done in polling mode.
- 25 feb 1995: 0.21a writes also in interrupt mode, still some
- small bugs to be found... Larger buffer.
- 2 mrt 1995: 0.22 Bug found (cd-> nowhere, interrupt was called in
- initialization), read_ahead of 16. Timeouts implemented.
- unclear if they do something...
- 7 mrt 1995: 0.23 Start of background read-ahead.
- 18 mrt 1995: 0.24 Working background read-ahead. (still problems)
- 26 mrt 1995: 0.25 Multi-session ioctl added (kernel v1.2).
- Statistics implemented, though separate stats206.h.
- Accessible through ioctl 0x1000 (just a number).
- Hard to choose between v1.2 development and 1.1.75.
- Bottom-half doesn't work with 1.2...
- 0.25a: fixed... typo. Still problems...
- 1 apr 1995: 0.26 Module support added. Most bugs found. Use kernel 1.2.n.
- 5 apr 1995: 0.27 Auto-probe for the adapter card base address.
- Auto-probe for the adaptor card irq line.
- 7 apr 1995: 0.28 Added lilo setup support for base address and irq.
- Use major number 32 (not in this source), officially
- assigned to this driver.
- 9 apr 1995: 0.29 Added very limited audio support. Toc_header, stop, pause,
- resume, eject. Play_track ignores track info, because we can't
- read a table-of-contents entry. Toc_entry is implemented
- as a `placebo' function: always returns start of disc.
- 3 may 1995: 0.30 Audio support completed. The get_toc_entry function
- is implemented as a binary search.
- 15 may 1995: 0.31 More work on audio stuff. Workman is not easy to
- satisfy; changed binary search into linear search.
- Auto-probe for base address somewhat relaxed.
- 1 jun 1995: 0.32 Removed probe_irq_on/off for module version.
- 10 jun 1995: 0.33 Workman still behaves funny, but you should be
- able to eject and substitute another disc.
-
- An adaptation of 0.33 is included in linux-1.3.7 by Eberhard Moenkeberg
-
- 18 jul 1995: 0.34 Patch by Heiko Eissfeldt included, mainly considering
- verify_area's in the ioctls. Some bugs introduced by
- EM considering the base port and irq fixed.
-
- 18 dec 1995: 0.35 Add some code for error checking... no luck...
-
- We jump to reach our goal: version 1.0 in the next stable linux kernel.
-
- 19 mar 1996: 0.95 Different implementation of CDROM_GET_UPC, on
- request of Thomas Quinot.
- 25 mar 1996: 0.96 Interpretation of opening with O_WRONLY or O_RDWR:
- open only for ioctl operation, e.g., for operation of
- tray etc.
- 4 apr 1996: 0.97 First implementation of layer between VFS and cdrom
- driver, a generic interface. Much of the functionality
- of cm206_open() and cm206_ioctl() is transferred to a
- new file cdrom.c and its header ucdrom.h.
-
- Upgrade to Linux kernel 1.3.78.
-
- 11 apr 1996 0.98 Upgrade to Linux kernel 1.3.85
- More code moved to cdrom.c
-
- 0.99 Some more small changes to decrease number
- of oopses at module load;
-
- 27 jul 1996 0.100 Many hours of debugging, kernel change from 1.2.13
- to 2.0.7 seems to have introduced some weird behavior
- in (interruptible_)sleep_on(&cd->data): the process
- seems to be woken without any explicit wake_up in my own
- code. Patch to try 100x in case such untriggered wake_up's
- occur.
-
- 28 jul 1996 0.101 Rewriting of the code that receives the command echo,
- using a fifo to store echoed bytes.
-
- Branch from 0.99:
-
- 0.99.1.0 Update to kernel release 2.0.10 dev_t -> kdev_t
- (emoenke) various typos found by others. extra
- module-load oops protection.
-
- 0.99.1.1 Initialization constant cdrom_dops.speed
- changed from float (2.0) to int (2); Cli()-sti() pair
- around cm260_reset() in module initialization code.
-
- 0.99.1.2 Changes literally as proposed by Scott Snyder
- <snyder@d0sgif.fnal.gov> for the 2.1 kernel line, which
- have to do mainly with the poor minor support i had. The
- major new concept is to change a cdrom driver's
- operations struct from the capabilities struct. This
- reflects the fact that there is one major for a driver,
- whilst there can be many minors whith completely
- different capabilities.
-
- 0.99.1.3 More changes for operations/info separation.
-
- 0.99.1.4 Added speed selection (someone had to do this
- first).
-
- 23 jan 1997 0.99.1.5 MODULE_PARMS call added.
-
- 23 jan 1997 0.100.1.2--0.100.1.5 following similar lines as
- 0.99.1.1--0.99.1.5. I get too many complaints about the
- drive making read errors. What't wrong with the 2.0+
- kernel line? Why get i (and othe cm206 owners) weird
- results? Why were things good in the good old 1.1--1.2
- era? Why don't i throw away the drive?
-
- 2 feb 1997 0.102 Added `volatile' to values in cm206_struct. Seems to
- reduce many of the problems. Rewrote polling routines
- to use fixed delays between polls.
- 0.103 Changed printk behavior.
- 0.104 Added a 0.100 -> 0.100.1.1 change
-
-11 feb 1997 0.105 Allow auto_probe during module load, disable
- with module option "auto_probe=0". Moved some debugging
- statements to lower priority. Implemented select_speed()
- function.
-
-13 feb 1997 1.0 Final version for 2.0 kernel line.
-
- All following changes will be for the 2.1 kernel line.
-
-15 feb 1997 1.1 Keep up with kernel 2.1.26, merge in changes from
- cdrom.c 0.100.1.1--1.0. Add some more MODULE_PARMS.
-
-14 sep 1997 1.2 Upgrade to Linux 2.1.55. Added blksize_size[], patch

-21 dec 1997 1.4 Upgrade to Linux 2.1.72.
-
-24 jan 1998 Removed the cm206_disc_status() function, as it was now dead
- code. The Uniform CDROM driver now provides this functionality.
-
-9 Nov. 1999 Make kernel-parameter implementation work with 2.3.x
- Removed init_module & cleanup_module in favor of
- module_init & module_exit.
- Torben Mathiasen <tmm@image.dk>
- *
- * Parts of the code are based upon lmscd.c written by Kai Petzke,
- * sbpcd.c written by Eberhard Moenkeberg, and mcd.c by Martin
- * Harriss, but any off-the-shelf dynamic programming algorithm won't
- * be able to find them.
- *
- * The cm206 drive interface and the cm260 adapter card seem to be
- * sufficiently different from their cm205/cm250 counterparts
- * in order to write a complete new driver.
- *
- * I call all routines connected to the Linux kernel something
- * with `cm206' in it, as this stuff is too series-dependent.
- *
- * Currently, my limited knowledge is based on:
- * - The Linux Kernel Hacker's guide, v. 0.5, by Michael K. Johnson
- * - Linux Kernel Programmierung, by Michael Beck and others
- * - Philips/LMS cm206 and cm226 product specification
- * - Philips/LMS cm260 product specification
- *

- *
- * 19 June 2004 -- check_region() converted to request_region()

-/* Revision history
-
-
- 14-5-95 v0.0 Plays sound tracks. No reading of data CDs yet.
- Detection of disk change doesn't work.
- 21-5-95 v0.1 First ALPHA version. CD can be mounted. The
- device major nr is borrowed from the Aztech
- driver. Speed is around 240 kb/s, as measured
- with "time dd if=/dev/cdrom of=/dev/null \
- bs=2048 count=4096".
- 24-6-95 v0.2 Reworked the #defines for the command codes
- and the like, as well as the structure of
- the hardware communication protocol, to
- reflect the "official" documentation, kindly
- supplied by C.K. Tan, Optics Storage Pte. Ltd.
- Also tidied up the state machine somewhat.
- 28-6-95 v0.3 Removed the ISP-16 interface code, as this
- should go into its own driver. The driver now
- has its own major nr.
- Disk change detection now seems to work, too.
- This version became part of the standard
- kernel as of version 1.3.7
- 24-9-95 v0.4 Re-inserted ISP-16 interface code which I
- copied from sjcd.c, with a few changes.
- Updated README.optcd. Submitted for
- inclusion in 1.3.21
- 29-9-95 v0.4a Fixed bug that prevented compilation as module
- 25-10-95 v0.5 Started multisession code. Implementation
- copied from Werner Zimmermann, who copied it
- from Heiko Schlittermann's mcdx.
- 17-1-96 v0.6 Multisession works; some cleanup too.
- 18-4-96 v0.7 Increased some timing constants;
- thanks to Luke McFarlane. Also tidied up some
- printk behaviour. ISP16 initialization
- is now handled by a separate driver.
-
- 09-11-99 Make kernel-parameter implementation work with 2.3.x
- Removed init_module & cleanup_module in favor of
- module_init & module_exit.

- *
- * VERSION HISTORY
- *
- * 0.1 initial release, April/May 93, after mcd.c (Martin Harriss)
- *
- * 0.2 thek "repeat:"-loop in do_sbpcd_request did not check for
- * end-of-request_queue (resulting in kernel panic).
- * Flow control seems stable, but throughput is not better.
- *
- * 0.3 interrupt locking totally eliminated (maybe "inb" and "outb"
- * are still locking) - 0.2 made keyboard-type-ahead losses.
- * check_sbpcd_media_change added (to use by isofs/inode.c)
- * - but it detects almost nothing.
- *
- * 0.4 use MAJOR 25 definitely.
- * Almost total re-design to support double-speed drives and
- * "naked" (no sound) interface cards ("LaserMate" interface type).
- * Flow control should be exact now.
- * Don't occupy the SbPro IRQ line (not needed either); will
- * live together with Hannu Savolainen's sndkit now.
- * Speeded up data transfer to 150 kB/sec, with help from Kai
- * Makisara, the "provider" of the "mt" tape utility.
- * Give "SpinUp" command if necessary.
- * First steps to support up to 4 drives (but currently only one).
- * Implemented audio capabilities - workman should work, xcdplayer
- * gives some problems.
- * This version is still consuming too much CPU time, and
- * sleeping still has to be worked on.
- * During "long" implied seeks, it seems possible that a
- * ReadStatus command gets ignored. That gives the message
- * "ResponseStatus timed out" (happens about 6 times here during
- * a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is
- * handled without data error, but it should get done better.
- *
- * 0.5 Free CPU during waits (again with help from Kai Makisara).
- * Made it work together with the LILO/kernel setup standard.
- * Included auto-probing code, as suggested by YGGDRASIL.
- * Formal redesign to add DDI debugging.
- * There are still flaws in IOCTL (workman with double speed drive).
- *
- * 1.0 Added support for all drive IDs (0...3, no longer only 0)
- * and up to 4 drives on one controller.
- * Added "#define MANY_SESSION" for "old" multi session CDs.
- *
- * 1.1 Do SpinUp for new drives, too.
- * Revised for clean compile under "old" kernels (0.99pl9).
- *
- * 1.2 Found the "workman with double-speed drive" bug: use the driver's
- * audio_state, not what the drive is reporting with ReadSubQ.
- *
- * 1.3 Minor cleanups.
- * Refinements regarding Workman.
- *
- * 1.4 Read XA disks (PhotoCDs) with "old" drives, too (but only the first
- * session - no chance to fully access a "multi-session" CD).
- * This currently still is too slow (50 kB/sec) - but possibly
- * the old drives won't do it faster.
- * Implemented "door (un)lock" for new drives (still does not work
- * as wanted - no lock possible after an unlock).
- * Added some debugging printout for the UPC/EAN code - but my drives
- * return only zeroes. Is there no UPC/EAN code written?
- *
- * 1.5 Laborate with UPC/EAN code (not better yet).
- * Adapt to kernel 1.1.8 change (have to explicitly include
- * <linux/string.h> now).
- *
- * 1.6 Trying to read audio frames as data. Impossible with the current
- * drive firmware levels, as it seems. Awaiting any hint. ;-)
- * Changed "door unlock": repeat it until success.
- * Changed CDROMSTOP routine (stop somewhat "softer" so that Workman
- * won't get confused).
- * Added a third interface type: Sequoia S-1000, as used with the SPEA
- * Media FX sound card. This interface (usable for Sony and Mitsumi
- * drives, too) needs a special configuration setup and behaves like a
- * LaserMate type after that. Still experimental - I do not have such
- * an interface.
- * Use the "variable BLOCK_SIZE" feature (2048). But it does only work
- * if you give the mount option "block=2048".
- * The media_check routine is currently disabled; now that it gets
- * called as it should I fear it must get synchronized for not to
- * disturb the normal driver's activity.
- *
- * 2.0 Version number bumped - two reasons:
- * - reading audio tracks as data works now with CR-562 and CR-563. We
- * currently do it by an IOCTL (yet has to get standardized), one frame
- * at a time; that is pretty slow. But it works.
- * - we are maintaining now up to 4 interfaces (each up to 4 drives):
- * did it the easy way - a different MAJOR (25, 26, ...) and a different
- * copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only
- * distinguished by the value of SBPCD_ISSUE and the driver's name),
- * and a common sbpcd.h file.
- * Bettered the "ReadCapacity error" problem with old CR-52x drives (the
- * drives sometimes need a manual "eject/insert" before work): just
- * reset the drive and do again. Needs lots of resets here and sometimes
- * that does not cure, so this can't be the solution.
- *
- * 2.1 Found bug with multisession CDs (accessing frame 16).
- * "read audio" works now with address type CDROM_MSF, too.
- * Bigger audio frame buffer: allows reading max. 4 frames at time; this
- * gives a significant speedup, but reading more than one frame at once
- * gives missing chunks at each single frame boundary.
- *
- * 2.2 Kernel interface cleanups: timers, init, setup, media check.
- *
- * 2.3 Let "door lock" and "eject" live together.
- * Implemented "close tray" (done automatically during open).
- *
- * 2.4 Use different names for device registering.
- *
- * 2.5 Added "#if EJECT" code (default: enabled) to automatically eject
- * the tray during last call to "sbpcd_release".
- * Added "#if JUKEBOX" code (default: disabled) to automatically eject
- * the tray during call to "sbpcd_open" if no disk is in.
- * Turn on the CD volume of "compatible" sound cards, too; just define
- * SOUND_BASE (in sbpcd.h) accordingly (default: disabled).
- *
- * 2.6 Nothing new.
- *
- * 2.7 Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly:
- * 0 disables, 1 enables auto-ejecting. Useful to keep the tray in
- * during shutdown.
- *
- * 2.8 Added first support (still BETA, I need feedback or a drive) for
- * the Longshine LCS-7260 drives. They appear as double-speed drives
- * using the "old" command scheme, extended by tray control and door
- * lock functions.
- * Found (and fixed preliminary) a flaw with some multisession CDs: we
- * have to re-direct not only the accesses to frame 16 (the isofs
- * routines drive it up to max. 100), but also those to the continuation
- * (repetition) frames (as far as they exist - currently set fix as
- * 16..20).
- * Changed default of the "JUKEBOX" define. If you use this default,
- * your tray will eject if you try to mount without a disk in. Next
- * mount command will insert the tray - so, just fill in a disk. ;-)
- *
- * 2.9 Fulfilled the Longshine LCS-7260 support; with great help and
- * experiments by Serge Robyns.
- * First attempts to support the TEAC CD-55A drives; but still not
- * usable yet.
- * Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle
- * multi session CDs more "transparent" (redirection handling has to be
- * done within the isofs routines, and only for the special purpose of
- * obtaining the "right" volume descriptor; accesses to the raw device
- * should not get redirected).
- *
- * 3.0 Just a "normal" increment, with some provisions to do it better. ;-)
- * Introduced "#define READ_AUDIO" to specify the maximum number of
- * audio frames to grab with one request. This defines a buffer size
- * within kernel space; a value of 0 will reserve no such space and
- * disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading
- * of a whole second with one command, but will use a buffer of more
- * than 172 kB.
- * Started CD200 support. Drive detection should work, but nothing
- * more.
- *
- * 3.1 Working to support the CD200 and the Teac CD-55A drives.
- * AT-BUS style device numbering no longer used: use SCSI style now.
- * So, the first "found" device has MINOR 0, regardless of the
- * jumpered drive ID. This implies modifications to the /dev/sbpcd*
- * entries for some people, but will help the DAU (german TLA, english:
- * "newbie", maybe ;-) to install his "first" system from a CD.
- *
- * 3.2 Still testing with CD200 and CD-55A drives.
- *
- * 3.3 Working with CD200 support.
- *
- * 3.4 Auto-probing stops if an address of 0 is seen (to be entered with
- * the kernel command line).
- * Made the driver "loadable". If used as a module, "audio copy" is
- * disabled, and the internal read ahead data buffer has a reduced size
- * of 4 kB; so, throughput may be reduced a little bit with slow CPUs.
- *
- * 3.5 Provisions to handle weird photoCDs which have an interrupted
- * "formatting" immediately after the last frames of some files: simply
- * never "read ahead" with MultiSession CDs. By this, CPU usage may be
- * increased with those CDs, and there may be a loss in speed.
- * Re-structured the messaging system.
- * The "loadable" version no longer has a limited READ_AUDIO buffer
- * size.
- * Removed "MANY_SESSION" handling for "old" multi session CDs.
- * Added "private" IOCTLs CDROMRESET and CDROMVOLREAD.
- * Started again to support the TEAC CD-55A drives, now that I found
- * the money for "my own" drive. ;-)
- * The TEAC CD-55A support is fairly working now.
- * I have measured that the drive "delivers" at 600 kB/sec (even with
- * bigger requests than the drive's 64 kB buffer can satisfy), but
- * the "real" rate does not exceed 520 kB/sec at the moment.
- * Caused by the various changes to build in TEAC support, the timed
- * loops are de-optimized at the moment (less throughput with CR-52x
- * drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64).
- *
- * 3.6 Fixed TEAC data read problems with SbPro interfaces.
- * Initial size of the READ_AUDIO buffer is 0. Can get set to any size
- * during runtime.
- *
- * 3.7 Introduced MAX_DRIVES for some poor interface cards (seen with TEAC
- * drives) which allow only one drive (ID 0); this avoids repetitive
- * detection under IDs 1..3.
- * Elongated cmd_out_T response waiting; necessary for photo CDs with
- * a lot of sessions.
- * Bettered the sbpcd_open() behavior with TEAC drives.
- *
- * 3.8 Elongated max_latency for CR-56x drives.
- *
- * 3.9 Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface
- * configuration bug.
- * Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy
- * the config_spea() routine into their drivers. ;-)
- *
- * 4.0 No "big step" - normal version increment.
- * Adapted the benefits from 1.3.33.
- * Fiddled with CDROMREADAUDIO flaws.
- * Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version
- * seems not to support it).
- * Fulfilled "read audio" for CD200 drives, with help of Pete Heist
- * (heistp@rpi.edu).
- *
- * 4.1 Use loglevel KERN_INFO with printk().
- * Added support for "Vertos 100" drive ("ECS-AT") - it is very similar
- * to the Longshine LCS-7260. Give feedback if you can - I never saw
- * such a drive, and I have no specs.
- *
- * 4.2 Support for Teac 16-bit interface cards. Can't get auto-detected,
- * so you have to jumper your card to 0x2C0. Still not 100% - come
- * in contact if you can give qualified feedback.
- * Use loglevel KERN_NOTICE with printk(). If you get annoyed by a
- * flood of unwanted messages and the accompanied delay, try to read
- * my documentation. Especially the Linux CDROM drivers have to do an
- * important job for the newcomers, so the "distributed" version has
- * to fit some special needs. Since generations, the flood of messages
- * is user-configurable (even at runtime), but to get aware of this, one
- * needs a special mental quality: the ability to read.
- *
- * 4.3 CD200F does not like to receive a command while the drive is
- * reading the ToC; still trying to solve it.
- * Removed some redundant verify_area calls (yes, Heiko Eissfeldt
- * is visiting all the Linux CDROM drivers ;-).
- *
- * 4.4 Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down"
- * experiments: "KLOGD_PAUSE".
- * Inhibited "play audio" attempts with data CDs. Provisions for a
- * "data-safe" handling of "mixed" (data plus audio) Cds.
- *
- * 4.5 Meanwhile Gonzalo Tornaria <tornaria@cmat.edu.uy> (GTL) built a
- * special end_request routine: we seem to have to take care for not
- * to have two processes working at the request list. My understanding
- * was and is that ll_rw_blk should not call do_sbpcd_request as long
- * as there is still one call active (the first call will care for all
- * outstanding I/Os, and if a second call happens, that is a bug in
- * ll_rw_blk.c).
- * "Check media change" without touching any drive.
- *
- * 4.6 Use a semaphore to synchronize multi-activity; elaborated by Rob
- * Riggs <rriggs@tesser.com>. At the moment, we simply block "read"
- * against "ioctl" and vice versa. This could be refined further, but
- * I guess with almost no performance increase.
- * Experiments to speed up the CD-55A; again with help of Rob Riggs
- * (to be true, he gave both, idea & code. ;-)
- *
- * 4.61 Ported to Uniform CD-ROM driver by
- * Heiko Eissfeldt <heiko@colossus.escape.de> with additional
- * changes by Erik Andersen <andersee@debian.org>
- *
- * 4.62 Fix a bug where playing audio left the drive in an unusable state.
- * Heiko Eissfeldt <heiko@colossus.escape.de>
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>
- *
- * 4.63 Bug fixes for audio annoyances, new legacy CDROM maintainer.
- * Annoying things fixed:
- * TOC reread on automated disk changes
- * TOC reread on manual cd changes
- * Play IOCTL tries to play CD before it's actually ready... sometimes.
- * CD_AUDIO_COMPLETED state so workman (and other playes) can repeat play.

- * Can also specify max_drives=N as a setup int to get rid of

- * remove alot of the virtual status bits and deal with hardware status

- * modify end_request and the block devices).
- *
- * In any case, the race here would be much small than it was, and
- * I couldn't reproduce..
- *
- * The race could be: suppose CURRENT==NULL. We put our req in the list,
- * and we are scheduled. Other process takes over, and gets into
- * do_sbpcd_request. It sees CURRENT!=NULL (it is == to our req), so

- * define your CDROM port base address as CDROM_PORT
- * and specify the type of your interface card as SBPRO.
- *
- * address:
- * ========
- * SBPRO type addresses typically are 0x0230 (=0x220+0x10), 0x0250, ...
- * LASERMATE type (CI-101P, WDH-7001C) addresses typically are 0x0300, ...
- * SOUNDSCAPE addresses are from the LASERMATE type and range. You have to
- * specify the REAL address here, not the configuration port address. Look
- * at the CDROM driver's invoking line within your DOS CONFIG.SYS, or let
- * sbpcd auto-probe, if you are not firm with the address.
- * There are some soundcards on the market with 0x0630, 0x0650, ...; their
- * type is not obvious (both types are possible).
- *
- * example: if your SBPRO audio address is 0x220, specify 0x230 and SBPRO 1.
- * if your soundcard has its CDROM port above 0x300, specify
- * that address and try SBPRO 0 first.
- * if your SoundScape configuration port is at 0x330, specify
- * 0x338 and SBPRO 2.
- *
- * interface type:
- * ===============
- * set SBPRO to 1 for "true" SoundBlaster card
- * set SBPRO to 0 for "compatible" soundcards and
- * for "poor" (no sound) interface cards.
- * set SBPRO to 2 for Ensonic SoundScape or SPEA Media FX cards
- * set SBPRO to 3 for Teac 16bit interface cards
- *
- * Almost all "compatible" sound boards need to set SBPRO to 0.
- * If SBPRO is set wrong, the drives will get found - but any
- * data access will give errors (audio access will work).
- * The "OmniCD" no-sound interface card from CreativeLabs and most Teac
- * interface cards need SBPRO 1.
- *
- * sound base:
- * ===========
- * The SOUND_BASE definition tells if we should try to turn the CD sound
- * channels on. It will only be of use regarding soundcards with a SbPro
- * compatible mixer.
- *
- * Example: #define SOUND_BASE 0x220 enables the sound card's CD channels
- * #define SOUND_BASE 0 leaves the soundcard untouched

- *
- * This driver is based on pre-works by Eberhard Moenkeberg (emoenke@gwdg.de);
- * it was developed under use of mcd.c from Martin Harriss, with help of
- * Eric van der Maarel (H.T.M.v.d.Maarel@marin.nl).
- *
- * It is planned to include these routines into sbpcd.c later - to make
- * a "mixed use" on one cable possible for all kinds of drives which use
- * the SoundBlaster/Panasonic style CDROM interface. But today, the
- * ability to install directly from CDROM is more important than flexibility.

- *
- * History:
- * 1.1 First public release with kernel version 1.3.7.
- * Written by Vadim Model.
- * 1.2 Added detection and configuration of cdrom interface
- * on ISP16 soundcard.
- * Allow for command line options: sjcd=<io_base>,<irq>,<dma>
- * 1.3 Some minor changes to README.sjcd.
- * 1.4 MSS Sound support!! Listen to a CD through the speakers.
- * 1.5 Module support and bugfixes.
- * Tray locking.
- * 1.6 Removed ISP16 code from this driver.
- * Allow only to set io base address on command line: sjcd=<io_base>
- * Changes to Documentation/cdrom/sjcd
- * Added cleanup after any error in the initialisation.
- * 1.7 Added code to set the sector size tables to prevent the bug present in
- * the previous version of this driver. Coded added by Anthony Barbachan
- * from bugfix tip originally suggested by Alan Cox.
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>

- * Sony CDU-535 interface device driver
- *
- * This is a modified version of the CDU-31A device driver (see below).
- * Changes were made using documentation for the CDU-531 (which Sony
- * assures me is very similar to the 535) and partial disassembly of the
- * DOS driver. I used Minyard's driver and replaced the CDU-31A
- * commands with the CDU-531 commands. This was complicated by a different
- * interface protocol with the drive. The driver is still polled.
- *
- * Data transfer rate is about 110 Kb/sec, theoretical maximum is 150 Kb/sec.
- * I tried polling without the sony_sleep during the data transfers but
- * it did not speed things up any.
- *
- * 1993-05-23 (rgj) changed the major number to 21 to get rid of conflict
- * with CDU-31A driver. This is the also the number from the Linux
- * Device Driver Registry for the Sony Drive. Hope nobody else is using it.
- *
- * 1993-08-29 (rgj) remove the configuring of the interface board address
- * from the top level configuration, you have to modify it in this file.
- *
- * 1995-01-26 Made module-capable (Joel Katz <Stimpson@Panix.COM>)
- *
- * 1995-05-20
- * Modified to support CDU-510/515 series
- * (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
- * Fixed to report verify_area() failures
- * (Heiko Eissfeldt <heiko@colossus.escape.de>)
- *
- * 1995-06-01
- * More changes to support CDU-510/515 series
- * (Claudio Porfiri<C.Porfiri@nisms.tei.ericsson.se>)
- *
- * November 1999 -- Make kernel-parameter implementation work with 2.3.x
- * Removed init_module & cleanup_module in favor of
- * module_init & module_exit.
- * Torben Mathiasen <tmm@image.dk>
- *
- * September 2003 - Fix SMP support by removing cli/sti calls.
- * Using spinlocks with a wait_queue instead.
- * Felipe Damasio <felipewd@terra.com.br>
- *
- * Things to do:
- * - handle errors and status better, put everything into a single word
- * - use interrupts (code mostly there, but a big hole still missing)
- * - handle multi-session CDs?
- * - use DMA?
- *
- * Known Bugs:

- * Original by:
- * Ron Jeppesen (ronj.an@site007.saic.com)

- *------------------------------------------------------------------------
- * Sony CDROM interface device driver.
- *
- * Corey Minyard (minyard@wf-rch.cirr.com) (CDU-535 complaints to Ken above)
- *
- * Colossians 3:17
- *
- * The Sony interface device driver handles Sony interface CDROM
- * drives and provides a complete block-level interface as well as an
- * ioctl() interface compatible with the Sun (as specified in
- * include/linux/cdrom.h). With this interface, CDROMs can be
- * accessed and standard audio CDs can be played back normally.
- *
- * This interface is (unfortunately) a polled interface. This is
- * because most Sony interfaces are set up with DMA and interrupts
- * disables. Some (like mine) do not even have the capability to
- * handle interrupts or DMA. For this reason you will see a bit of
- * the following:
- *
- * snap = jiffies;
- * while (jiffies-snap < SONY_JIFFIES_TIMEOUT)
- * {
- * if (some_condition())
- * break;
- * sony_sleep();
- * }
- * if (some_condition not met)
- * {
- * return an_error;
- * }
- *
- * This ugly hack waits for something to happen, sleeping a little
- * between every try. (The conditional is written so that jiffies
- * wrap-around is handled properly.)
- *
- * One thing about these drives: They talk in MSF (Minute Second Frame) format.
- * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a
- * disk. The funny thing is that these are sent to the drive in BCD, but the
- * interface wants to see them in decimal. A lot of conversion goes on.

+/* lasi_82596.c -- driver for the intel 82596 ethernet controller, as
+ munged into HPPA boxen .
+
+ This driver is based upon 82596.c, original credits are below...
+ but there were too many hoops which HP wants jumped through to
+ keep this code in there in a sane manner.
+
+ 3 primary sources of the mess --
+ 1) hppa needs *lots* of cacheline flushing to keep this kind of
+ MMIO running.
+
+ 2) The 82596 needs to see all of its pointers as their physical
+ address. Thus virt_to_bus/bus_to_virt are *everywhere*.
+
+ 3) The implementation HP is using seems to be significantly pickier
+ about when and how the command and RX units are started. some
+ command ordering was changed.
+
+ Examination of the mach driver leads one to believe that there
+ might be a saner way to pull this off... anyone who feels like a
+ full rewrite can be my guest.
+
+ Split 02/13/2000 Sam Creasey (sammy@oh.verio.com)

+ 02/01/2000 Initial modifications for parisc by Helge Deller (deller@gmx.de)
+ 03/02/2000 changes for better/correct(?) cache-flushing (deller)

+
+/* 82596.c: A generic 82596 ethernet driver for linux. */
+/*
+ Based on Apricot.c
+ Written 1994 by Mark Evans.
+ This driver is for the Apricot 82596 bus-master interface
+
+ Modularised 12/94 Mark Evans
+
+
+ Modified to support the 82596 ethernet chips on 680x0 VME boards.
+ by Richard Hirst <richard@sleepie.demon.co.uk>
+ Renamed to be 82596.c
+
+ 980825: Changed to receive directly in to sk_buffs which are
+ allocated at open() time. Eliminates copy on incoming frames
+ (small ones are still copied). Shared data now held in a
+ non-cached page, so we can run on 68060 in copyback mode.
+
+ TBD:
+ * look at deferring rx frames rather than discarding (as per tulip)
+ * handle tx ring full as per tulip
+ * performace test to tune rx_copybreak
+
+ Most of my modifications relate to the braindead big-endian
+ implementation by Intel. When the i596 is operating in
+ 'big-endian' mode, it thinks a 32 bit value of 0x12345678
+ should be stored as 0x56781234. This is a real pain, when
+ you have linked lists which are shared by the 680x0 and the
+ i596.

-=========================================================================
- r8169.c: A RealTek RTL-8169 Gigabit Ethernet driver for Linux kernel 2.4.x.
- --------------------------------------------------------------------
-
- History:
- Feb 4 2002 - created initially by ShuChen <shuchen@realtek.com.tw>.
- May 20 2002 - Add link status force-mode and TBI mode support.
- 2004 - Massive updates. See kernel SCM system for details.
-=========================================================================
- 1. [DEPRECATED: use ethtool instead] The media can be forced in 5 modes.
- Command: 'insmod r8169 media = SET_MEDIA'
- Ex: 'insmod r8169 media = 0x04' will force PHY to operate in 100Mpbs Half-duplex.
-
- SET_MEDIA can be:
- _10_Half = 0x01
- _10_Full = 0x02
- _100_Half = 0x04
- _100_Full = 0x08
- _1000_Full = 0x10
-
- 2. Support TBI mode.
-=========================================================================
-VERSION 1.1 <2002/10/4>
-
- The bit4:0 of MII register 4 is called "selector field", and have to be
- 00001b to indicate support of IEEE std 802.3 during NWay process of
- exchanging Link Code Word (FLP).
-
-VERSION 1.2 <2002/11/30>
-
- - Large style cleanup
- - Use ether_crc in stock kernel (linux/crc32.h)
- - Copy mc_filter setup code from 8139cp
- (includes an optimization, and avoids set_bit use)
-
-VERSION 1.6LK <2004/04/14>
-
- - Merge of Realtek's version 1.6
- - Conversion to DMA API
- - Suspend/resume
- - Endianness
- - Misc Rx/Tx bugs
-
-VERSION 2.2LK <2005/01/25>
-
- - RX csum, TX csum/SG, TSO
- - VLAN
- - baby (< 7200) Jumbo frames support
- - Merge of Realtek's version 2.2 (new phy)

* mode of the other lock."
*
- * Part 2: if the granted mode of lkb is preventing the first lkb in the
- * convert queue from being granted, then demote lkb (set grmode to NL).
- * This second form requires that we check for conv-deadlk even when
- * now == 0 in _can_be_granted().
+ * Part 2: if the granted mode of lkb is preventing an earlier lkb in the
+ * convert queue from being granted, then deadlk/demote lkb.
*
* Example:
* Granted Queue: empty
*
* The first lock can't be granted because of the granted mode of the second
* lock and the second lock can't be granted because it's not first in the
- * list. We demote the granted mode of the second lock (the lkb passed to this
- * function).
+ * list. We either cancel lkb's conversion (PR->EX) and return EDEADLK, or we
+ * demote the granted mode of lkb (from PR to NL) if it has the CONVDEADLK
+ * flag set and return DEMOTED in the lksb flags.
+ *
+ * Originally, this function detected conv-deadlk in a more limited scope:
+ * - if !modes_compat(lkb1, lkb2) && !modes_compat(lkb2, lkb1), or
+ * - if lkb1 was the first entry in the queue (not just earlier), and was
+ * blocked by the granted mode of lkb2, and there was nothing on the
+ * granted queue preventing lkb1 from being granted immediately, i.e.
+ * lkb2 was the only thing preventing lkb1 from being granted.
+ *
+ * That second condition meant we'd only say there was conv-deadlk if
+ * resolving it (by demotion) would lead to the first lock on the convert
+ * queue being granted right away. It allowed conversion deadlocks to exist
+ * between locks on the convert queue while they couldn't be granted anyway.
*
- * After the resolution, the "grant pending" function needs to go back and try
- * to grant locks on the convert queue again since the first lock can now be
- * granted.
+ * Now, we detect and take action on conversion deadlocks immediately when
+ * they're created, even if they may not be immediately consequential. If
+ * lkb1 exists anywhere in the convert queue and lkb2 comes in with a granted
+ * mode that would prevent lkb1's conversion from being granted, we do a
+ * deadlk/demote on lkb2 right away and don't let it onto the convert queue.
+ * I think this means that the lkb_is_ahead condition below should always
+ * be zero, i.e. there will never be conv-deadlk between two locks that are
+ * both already on the convert queue.

+ * SMP/VPE-safe functions to access "registers" (see note).
+ *
+ * NOTES:
+* - These macros use ll/sc instructions, so it is your responsibility to
+ * ensure these are available on your platform before including this file.
+ * - The MIPS32 spec states that ll/sc results are undefined for uncached
+ * accesses. This means they can't be used on HW registers accessed
+ * through kseg1. Code which requires these macros for this purpose must
+ * front-end the registers with cached memory "registers" and have a single
+ * thread update the actual HW registers.
+ * - A maximum of 2k of code can be inserted between ll and sc. Every
+ * memory accesses between the instructions will increase the chance of
+ * sc failing and having to loop.
+ * - When using custom_read_reg32/custom_write_reg32 only perform the
+ * necessary logical operations on the register value in between these
+ * two calls. All other logic should be performed before the first call.
+ * - There is a bug on the R10000 chips which has a workaround. If you
+ * are affected by this bug, make sure to define the symbol 'R10000_LLSC_WAR'
+ * to be non-zero. If you are using this header from within linux, you may
+ * include <asm/war.h> before including this file to have this defined
+ * appropriately for you.

+ * 0x68. The SPI driver definitions for the register must be aware
+ * of this.
+ * 2) The block copy engine register are divided into two regions, one
+ * for the control/configuration of the engine proper and one for the
+ * values of the descriptors used in the copy process. These have
+ * different base defines (CTRL_BASE vs DESC_BASE)
+ * 3) These constants are for physical addresses which means that they
+ * work correctly with "ioremap" and friends. This means that device
+ * drivers will need to remap these addresses using ioremap and perhaps
+ * the readw/writew macros. Or they could use the regptr() macro
+ * defined below, but the readw/writew calls are the correct thing.
+ * 4) The UARTs have an additional status register offset from the base
+ * address. This register isn't used in the standard 8250 driver but
+ * may be used in other software. Consult the hardware datasheet for
+ * offset details.
+ * 5) For some unknown reason the security engine (MSP_SEC_BASE) registers
+ * start at an offset of 0x84 from the base address but the block of
+ * registers before this is reserved for the security engine. The
+ * driver will have to be aware of this but it makes the register
+ * definitions line up better with the documentation.

- * If a task is 'interactive' then we reinsert it in the active

- *
- * This part scales the interactivity limit depending on niceness.
- *
- * We scale it linearly, offset by the INTERACTIVE_DELTA delta.
- * Here are a few examples of different nice levels:
- *
- * TASK_INTERACTIVE(-20): [1,1,1,1,1,1,1,1,1,0,0]
- * TASK_INTERACTIVE(-10): [1,1,1,1,1,1,1,0,0,0,0]

- *
- * (the X axis represents the possible -5 ... 0 ... +5 dynamic
- * priority range a task can explore, a value of '1' means the
- * task is rated interactive.)
- *
- * Ie. nice +19 tasks can never get 'interactive' enough to be
- * reinserted into the active array. And only heavily CPU-hog nice -20
- * tasks will be expired. Default nice 0 tasks are somewhere between,
