Introduction
------------
-
-Currently the ALPS touchpad driver supports four protocol versions in use by
-ALPS touchpads, called versions 1, 2, 3, and 4. Information about the various
-protocol versions is contained in the following sections.
+Currently the ALPS touchpad driver supports five protocol versions in use by
+ALPS touchpads, called versions 1, 2, 3, 4 and 5.
+
+Since roughly mid-2010 several new ALPS touchpads have been released and
+integrated into a variety of laptops and netbooks. These new touchpads
+have enough behavior differences that the alps_model_data definition
+table, describing the properties of the different versions, is no longer
+adequate. The design choices were to re-define the alps_model_data
+table, with the risk of regression testing existing devices, or isolate
+the new devices outside of the alps_model_data table. The latter design
+choice was made. The new touchpad signatures are named: "Rushmore",
+"Pinnacle", and "Dolphin", which you will see in the alps.c code.
+For the purposes of this document, this group of ALPS touchpads will
+generically be called "new ALPS touchpads".
+
+We experimented with probing the ACPI interface _HID (Hardware ID)/_CID
+(Compatibility ID) definition as a way to uniquely identify the
+different ALPS variants but there did not appear to be a 1:1 mapping.
+In fact, it appeared to be an m:n mapping between the _HID and actual
+hardware type.
Detection
---------
report" sequence: E8-E7-E7-E7-E9. The response is the model signature and is
matched against known models in the alps_model_data_array.
-With protocol versions 3 and 4, the E7 report model signature is always
-73-02-64. To differentiate between these versions, the response from the
-"Enter Command Mode" sequence must be inspected as described below.
+For older touchpads supporting protocol versions 3 and 4, the E7 report
+model signature is always 73-02-64. To differentiate between these
+versions, the response from the "Enter Command Mode" sequence must be
+inspected as described below.
+
+The new ALPS touchpads have an E7 signature of 73-03-50 or 73-03-0A but
+seem to be better differentiated by the EC Command Mode response.
Command Mode
------------
register. Registers are written by writing the value one nibble at a time
using the same encoding used for addresses.
+For the new ALPS touchpads, the EC command is used to enter command
+mode. The response in the new ALPS touchpads is significantly different,
+and more important in determining the behavior. This code has been
+separated from the original alps_model_data table and put in the
+alps_identify function. For example, there seem to be two hardware init
+sequences for the "Dolphin" touchpads as determined by the second byte
+of the EC response.
+
Packet Format
-------------
well.
So far no v4 devices with tracksticks have been encountered.
+
+ALPS Absolute Mode - Protocol Version 5
+---------------------------------------
+This is basically Protocol Version 3 but with different logic for packet
+decode. It uses the same alps_process_touchpad_packet_v3 call with a
+specialized decode_fields function pointer to correctly interpret the
+packets. This appears to only be used by the Dolphin devices.
+
+For single-touch, the 6-byte packet format is:
+
+ byte 0: 1 1 0 0 1 0 0 0
+ byte 1: 0 x6 x5 x4 x3 x2 x1 x0
+ byte 2: 0 y6 y5 y4 y3 y2 y1 y0
+ byte 3: 0 M R L 1 m r l
+ byte 4: y10 y9 y8 y7 x10 x9 x8 x7
+ byte 5: 0 z6 z5 z4 z3 z2 z1 z0
+
+For mt, the format is:
+
+ byte 0: 1 1 1 n3 1 n2 n1 x24
+ byte 1: 1 y7 y6 y5 y4 y3 y2 y1
+ byte 2: ? x2 x1 y12 y11 y10 y9 y8
+ byte 3: 0 x23 x22 x21 x20 x19 x18 x17

+ 3.3 Multiqueue tuntap interface:
+
+ From version 3.8, Linux supports multiqueue tuntap which can uses multiple
+ file descriptors (queues) to parallelize packets sending or receiving. The
+ device allocation is the same as before, and if user wants to create multiple
+ queues, TUNSETIFF with the same device name must be called many times with
+ IFF_MULTI_QUEUE flag.
+
+ char *dev should be the name of the device, queues is the number of queues to
+ be created, fds is used to store and return the file descriptors (queues)
+ created to the caller. Each file descriptor were served as the interface of a
+ queue which could be accessed by userspace.
+
+ #include <linux/if.h>
+ #include <linux/if_tun.h>
+
+ int tun_alloc_mq(char *dev, int queues, int *fds)
+ {
+ struct ifreq ifr;
+ int fd, err, i;
+
+ if (!dev)
+ return -1;
+
+ memset(&ifr, 0, sizeof(ifr));
+ /* Flags: IFF_TUN - TUN device (no Ethernet headers)
+ * IFF_TAP - TAP device
+ *
+ * IFF_NO_PI - Do not provide packet information
+ * IFF_MULTI_QUEUE - Create a queue of multiqueue device
+ */
+ ifr.ifr_flags = IFF_TAP | IFF_NO_PI | IFF_MULTI_QUEUE;
+ strcpy(ifr.ifr_name, dev);
+
+ for (i = 0; i < queues; i++) {
+ if ((fd = open("/dev/net/tun", O_RDWR)) < 0)
+ goto err;
+ err = ioctl(fd, TUNSETIFF, (void *)&ifr);
+ if (err) {
+ close(fd);
+ goto err;
+ }
+ fds[i] = fd;
+ }
+
+ return 0;
+ err:
+ for (--i; i >= 0; i--)
+ close(fds[i]);
+ return err;
+ }
+
+ A new ioctl(TUNSETQUEUE) were introduced to enable or disable a queue. When
+ calling it with IFF_DETACH_QUEUE flag, the queue were disabled. And when
+ calling it with IFF_ATTACH_QUEUE flag, the queue were enabled. The queue were
+ enabled by default after it was created through TUNSETIFF.
+
+ fd is the file descriptor (queue) that we want to enable or disable, when
+ enable is true we enable it, otherwise we disable it
+
+ #include <linux/if.h>
+ #include <linux/if_tun.h>
+
+ int tun_set_queue(int fd, int enable)
+ {
+ struct ifreq ifr;
+
+ memset(&ifr, 0, sizeof(ifr));
+
+ if (enable)
+ ifr.ifr_flags = IFF_ATTACH_QUEUE;
+ else
+ ifr.ifr_flags = IFF_DETACH_QUEUE;
+
+ return ioctl(fd, TUNSETQUEUE, (void *)&ifr);

1. Introduction
===============
+1.1 What is an Operating Performance Point (OPP)?
+
Complex SoCs of today consists of a multiple sub-modules working in conjunction.
In an operational system executing varied use cases, not all modules in the SoC
need to function at their highest performing frequency all the time. To
facilitate this, sub-modules in a SoC are grouped into domains, allowing some
-domains to run at lower voltage and frequency while other domains are loaded
-more. The set of discrete tuples consisting of frequency and voltage pairs that
+domains to run at lower voltage and frequency while other domains run at
+voltage/frequency pairs that are higher.
+
+The set of discrete tuples consisting of frequency and voltage pairs that
the device will support per domain are called Operating Performance Points or
OPPs.
+As an example:
+Let us consider an MPU device which supports the following:
+{300MHz at minimum voltage of 1V}, {800MHz at minimum voltage of 1.2V},
+{1GHz at minimum voltage of 1.3V}
+
+We can represent these as three OPPs as the following {Hz, uV} tuples:
+{300000000, 1000000}
+{800000000, 1200000}
+{1000000000, 1300000}
+
+1.2 Operating Performance Points Library
+
OPP library provides a set of helper functions to organize and query the OPP
information. The library is located in drivers/base/power/opp.c and the header
is located in include/linux/opp.h. OPP library can be enabled by enabling

* VSID allocation (256MB segment)
*
- * We first generate a 38-bit "proto-VSID". For kernel addresses this
- * is equal to the ESID | 1 << 37, for user addresses it is:
- * (context << USER_ESID_BITS) | (esid & ((1U << USER_ESID_BITS) - 1)
+ * We first generate a 37-bit "proto-VSID". Proto-VSIDs are generated
+ * from mmu context id and effective segment id of the address.
*
- * This splits the proto-VSID into the below range
- * 0 - (2^(CONTEXT_BITS + USER_ESID_BITS) - 1) : User proto-VSID range
- * 2^(CONTEXT_BITS + USER_ESID_BITS) - 2^(VSID_BITS) : Kernel proto-VSID range
- *
- * We also have CONTEXT_BITS + USER_ESID_BITS = VSID_BITS - 1
- * That is, we assign half of the space to user processes and half
- * to the kernel.
+ * For user processes max context id is limited to ((1ul << 19) - 5)
+ * for kernel space, we use the top 4 context ids to map address as below
+ * NOTE: each context only support 64TB now.
+ * 0x7fffc - [ 0xc000000000000000 - 0xc0003fffffffffff ]
+ * 0x7fffd - [ 0xd000000000000000 - 0xd0003fffffffffff ]
+ * 0x7fffe - [ 0xe000000000000000 - 0xe0003fffffffffff ]
+ * 0x7ffff - [ 0xf000000000000000 - 0xf0003fffffffffff ]
*
* The proto-VSIDs are then scrambled into real VSIDs with the
* multiplicative hash:
* VSID_MULTIPLIER is prime, so in particular it is
* co-prime to VSID_MODULUS, making this a 1:1 scrambling function.
* Because the modulus is 2^n-1 we can compute it efficiently without
- * a divide or extra multiply (see below).
- *
- * This scheme has several advantages over older methods:
- *
- * - We have VSIDs allocated for every kernel address
- * (i.e. everything above 0xC000000000000000), except the very top
- * segment, which simplifies several things.
+ * a divide or extra multiply (see below). The scramble function gives
+ * robust scattering in the hash table (at least based on some initial
+ * results).
*
- * - We allow for USER_ESID_BITS significant bits of ESID and
- * CONTEXT_BITS bits of context for user addresses.
- * i.e. 64T (46 bits) of address space for up to half a million contexts.
+ * We also consider VSID 0 special. We use VSID 0 for slb entries mapping
+ * bad address. This enables us to consolidate bad address handling in
+ * hash_page.
*
- * - The scramble function gives robust scattering in the hash
- * table (at least based on some initial results). The previous
- * method was more susceptible to pathological cases giving excessive
- * hash collisions.
+ * We also need to avoid the last segment of the last context, because that
+ * would give a protovsid of 0x1fffffffff. That will result in a VSID 0
+ * because of the modulo operation in vsid scramble. But the vmemmap
+ * (which is what uses region 0xf) will never be close to 64TB in size
+ * (it's 56 bytes per page of system memory).

- * How to be a proc read function
- * ------------------------------
- * Prototype:
- * int f(char *buffer, char **start, off_t offset,
- * int count, int *peof, void *dat)
- *
- * Assume that the buffer is "count" bytes in size.
- *
- * If you know you have supplied all the data you
- * have, set *peof.
- *
- * You have three ways to return data:
- * 0) Leave *start = NULL. (This is the default.)
- * Put the data of the requested offset at that
- * offset within the buffer. Return the number (n)
- * of bytes there are from the beginning of the
- * buffer up to the last byte of data. If the
- * number of supplied bytes (= n - offset) is
- * greater than zero and you didn't signal eof
- * and the reader is prepared to take more data
- * you will be called again with the requested
- * offset advanced by the number of bytes
- * absorbed. This interface is useful for files
- * no larger than the buffer.
- * 1) Set *start = an unsigned long value less than
- * the buffer address but greater than zero.
- * Put the data of the requested offset at the
- * beginning of the buffer. Return the number of
- * bytes of data placed there. If this number is
- * greater than zero and you didn't signal eof
- * and the reader is prepared to take more data
- * you will be called again with the requested
- * offset advanced by *start. This interface is
- * useful when you have a large file consisting
- * of a series of blocks which you want to count
- * and return as wholes.
- * (Hack by Paul.Russell@rustcorp.com.au)
- * 2) Set *start = an address within the buffer.
- * Put the data of the requested offset at *start.
- * Return the number of bytes of data placed there.
- * If this number is greater than zero and you
- * didn't signal eof and the reader is prepared to
- * take more data you will be called again with the
- * requested offset advanced by the number of bytes
- * absorbed.

-/* Write @count bytes at position @ppos in a file indicated by @file

-
- generic_file_write() is only appropriate for filesystems that are not seeking to optimize performance and want
- something simple that works. It is not for serious use by general purpose filesystems, excepting the one that it was
- written for (ext2/3). This is for several reasons:
-
- * It has no understanding of any filesystem specific optimizations.
-
- * It enters the filesystem repeatedly for each page that is written.
-
- * It depends on reiserfs_get_block() function which if implemented by reiserfs performs costly search_by_key
- * operation for each page it is supplied with. By contrast reiserfs_file_write() feeds as much as possible at a time
- * to reiserfs which allows for fewer tree traversals.
-
- * Each indirect pointer insertion takes a lot of cpu, because it involves memory moves inside of blocks.
-
- * Asking the block allocation code for blocks one at a time is slightly less efficient.
-
- All of these reasons for not using only generic file write were understood back when reiserfs was first miscoded to
- use it, but we were in a hurry to make code freeze, and so it couldn't be revised then. This new code should make
- things right finally.
-
- Future Features: providing search_by_key with hints.
