+
+Driver source code path
+ drivers/soc/ti/knav_qmss.c
+ drivers/soc/ti/knav_qmss_acc.c
+
+The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
+the main hardware sub system which forms the backbone of the Keystone
+multi-core Navigator. QMSS consist of queue managers, packed-data structure
+processors(PDSP), linking RAM, descriptor pools and infrastructure
+Packet DMA.
+The Queue Manager is a hardware module that is responsible for accelerating
+management of the packet queues. Packets are queued/de-queued by writing or
+reading descriptor address to a particular memory mapped location. The PDSPs
+perform QMSS related functions like accumulation, QoS, or event management.
+Linking RAM registers are used to link the descriptors which are stored in
+descriptor RAM. Descriptor RAM is configurable as internal or external memory.
+The QMSS driver manages the PDSP setups, linking RAM regions,
+queue pool management (allocation, push, pop and notify) and descriptor
+pool management.
+
+knav qmss driver provides a set of APIs to drivers to open/close qmss queues,
+allocate descriptor pools, map the descriptors, push/pop to queues etc. For
+details of the available APIs, please refers to include/linux/soc/ti/knav_qmss.h
+
+DT documentation is available at
+Documentation/devicetree/bindings/soc/ti/keystone-navigator-qmss.txt
+
+Accumulator QMSS queues using PDSP firmware
+============================================
+The QMSS PDSP firmware support accumulator channel that can monitor a single
+queue or multiple contiguous queues. drivers/soc/ti/knav_qmss_acc.c is the
+driver that interface with the accumulator PDSP. This configures
+accumulator channels defined in DTS (example in DT documentation) to monitor
+1 or 32 queues per channel. More description on the firmware is available in
+CPPI/QMSS Low Level Driver document (docs/CPPI_QMSS_LLD_SDS.pdf) at
+ git://git.ti.com/keystone-rtos/qmss-lld.git
+
+k2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin firmware supports upto 48 accumulator
+channels. This firmware is available under ti-keystone folder of
+firmware.git at
+ git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
+
+To use copy the firmware image to lib/firmware folder of the initramfs or
+ubifs file system and provide a sym link to k2_qmss_pdsp_acc48_k2_le_1_0_0_9.bin
+in the file system and boot up the kernel. User would see
+
+ "firmware file ks2_qmss_pdsp_acc48.bin downloaded for PDSP"
+
+in the boot up log if loading of firmware to PDSP is successful.
+
+Use of accumulated queues requires the firmware image to be present in the
+file system. The driver doesn't acc queues to the supported queue range if
+PDSP is not running in the SoC. The API call fails if there is a queue open
+request to an acc queue and PDSP is not running. So make sure to copy firmware
+to file system before using these queue types.

+System Control and Power Interface (SCPI) Message Protocol
+----------------------------------------------------------
+
+Firmware implementing the SCPI described in ARM document number ARM DUI 0922B
+("ARM Compute Subsystem SCP: Message Interface Protocols")[0] can be used
+by Linux to initiate various system control and power operations.
+
+Required properties:
+
+- compatible : should be "arm,scpi"
+- mboxes: List of phandle and mailbox channel specifiers
+ All the channels reserved by remote SCP firmware for use by
+ SCPI message protocol should be specified in any order
+- shmem : List of phandle pointing to the shared memory(SHM) area between the
+ processors using these mailboxes for IPC, one for each mailbox
+ SHM can be any memory reserved for the purpose of this communication
+ between the processors.
+
+See Documentation/devicetree/bindings/mailbox/mailbox.txt
+for more details about the generic mailbox controller and
+client driver bindings.
+
+Clock bindings for the clocks based on SCPI Message Protocol
+------------------------------------------------------------
+
+This binding uses the common clock binding[1].
+
+Container Node
+==============
+Required properties:
+- compatible : should be "arm,scpi-clocks"
+ All the clocks provided by SCP firmware via SCPI message
+ protocol much be listed as sub-nodes under this node.
+
+Sub-nodes
+=========
+Required properties:
+- compatible : shall include one of the following
+ "arm,scpi-dvfs-clocks" - all the clocks that are variable and index based.
+ These clocks don't provide an entire range of values between the
+ limits but only discrete points within the range. The firmware
+ provides the mapping for each such operating frequency and the
+ index associated with it. The firmware also manages the
+ voltage scaling appropriately with the clock scaling.
+ "arm,scpi-variable-clocks" - all the clocks that are variable and provide full
+ range within the specified range. The firmware provides the
+ range of values within a specified range.
+
+Other required properties for all clocks(all from common clock binding):
+- #clock-cells : Should be 1. Contains the Clock ID value used by SCPI commands.
+- clock-output-names : shall be the corresponding names of the outputs.
+- clock-indices: The identifying number for the clocks(i.e.clock_id) in the
+ node. It can be non linear and hence provide the mapping of identifiers
+ into the clock-output-names array.
+
+SRAM and Shared Memory for SCPI
+-------------------------------
+
+A small area of SRAM is reserved for SCPI communication between application
+processors and SCP.
+
+Required properties:
+- compatible : should be "arm,juno-sram-ns" for Non-secure SRAM on Juno
+
+The rest of the properties should follow the generic mmio-sram description
+found in ../../misc/sysram.txt
+
+Each sub-node represents the reserved area for SCPI.
+
+Required sub-node properties:
+- reg : The base offset and size of the reserved area with the SRAM
+- compatible : should be "arm,juno-scp-shmem" for Non-secure SRAM based
+ shared memory on Juno platforms
+
+Sensor bindings for the sensors based on SCPI Message Protocol
+--------------------------------------------------------------
+SCPI provides an API to access the various sensors on the SoC.
+
+Required properties:
+- compatible : should be "arm,scpi-sensors".
+- #thermal-sensor-cells: should be set to 1. This property follows the
+ thermal device tree bindings[2].
+
+ Valid cell values are raw identifiers (Sensor
+ ID) as used by the firmware. Refer to
+ platform documentation for your
+ implementation for the IDs to use. For Juno
+ R0 and Juno R1 refer to [3].

+ clocks {
+ compatible = "arm,scpi-clocks";
+
+ scpi_dvfs: scpi_clocks@0 {
+ compatible = "arm,scpi-dvfs-clocks";
+ #clock-cells = <1>;
+ clock-indices = <0>, <1>, <2>;
+ clock-output-names = "atlclk", "aplclk","gpuclk";
+ };
+ scpi_clk: scpi_clocks@3 {
+ compatible = "arm,scpi-variable-clocks";
+ #clock-cells = <1>;
+ clock-indices = <3>, <4>;
+ clock-output-names = "pxlclk0", "pxlclk1";
+ };

+
+ scpi_sensors0: sensors {

+
+cpu@0 {

+ polling-delay = <1000>;
+
+ /* sensor ID */
+ thermal-sensors = <&scpi_sensors0 3>;
+ ...
+ };
+};
+
+In the above example, the #clock-cells is set to 1 as required.
+scpi_dvfs has 3 output clocks namely: atlclk, aplclk, and gpuclk with 0,
+1 and 2 as clock-indices. scpi_clk has 2 output clocks namely: pxlclk0
+and pxlclk1 with 3 and 4 as clock-indices.
+
+The first consumer in the example is cpu@0 and it has '0' as the clock
+specifier which points to the first entry in the output clocks of
+scpi_dvfs i.e. "atlclk".
+
+Similarly the second example is hdlcd@7ff60000 and it has pxlclk1 as input
+clock. '4' in the clock specifier here points to the second entry
+in the output clocks of scpi_clocks i.e. "pxlclk1"
+
+The thermal-sensors property in the soc_thermal node uses the
+temperature sensor provided by SCP firmware to setup a thermal
+zone. The ID "3" is the sensor identifier for the temperature sensor
+as used by the firmware.

+hif-cpubiuctrl node
+-------------------
+SoCs with Broadcom Brahma15 ARM-based CPUs have a specific Bus Interface Unit
+(BIU) block which controls and interfaces the CPU complex to the different
+Memory Controller Ports (MCP), one per memory controller (MEMC). This BIU block
+offers a feature called Write Pairing which consists in collapsing two adjacent
+cache lines into a single (bursted) write transaction towards the memory
+controller (MEMC) to maximize write bandwidth.
+
+Required properties:
+
+ - compatible: must be "brcm,bcm7445-hif-cpubiuctrl", "syscon"
+
+Optional properties:
+
+ - brcm,write-pairing:
+ Boolean property, which when present indicates that the chip
+ supports write-pairing.

+
+Power management
+----------------
+
+For power management (particularly, S2/S3/S5 system suspend), the following SoC
+components are needed:
+
+= Always-On control block (AON CTRL)
+
+This hardware provides control registers for the "always-on" (even in low-power
+modes) hardware, such as the Power Management State Machine (PMSM).
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-aon-ctrl"
+- reg : the register start and length for the AON CTRL block
+
+Example:
+
+aon-ctrl@410000 {
+ compatible = "brcm,brcmstb-aon-ctrl";
+ reg = <0x410000 0x400>;
+};
+
+= Memory controllers
+
+A Broadcom STB SoC typically has a number of independent memory controllers,
+each of which may have several associated hardware blocks, which are versioned
+independently (control registers, DDR PHYs, etc.). One might consider
+describing these controllers as a parent "memory controllers" block, which
+contains N sub-nodes (one for each controller in the system), each of which is
+associated with a number of hardware register resources (e.g., its PHY). See
+the example device tree snippet below.
+

device tree bindings for your controller.
GPIOs mappings are defined in the consumer device's node, in a property named
-<function>-gpios, where <function> is the function the driver will request
-through gpiod_get(). For example:
+either <function>-gpios or <function>-gpio, where <function> is the function
+the driver will request through gpiod_get(). For example:
foo_device {
compatible = "acme,foo";
<&gpio 16 GPIO_ACTIVE_HIGH>, /* green */
<&gpio 17 GPIO_ACTIVE_HIGH>; /* blue */
- power-gpios = <&gpio 1 GPIO_ACTIVE_LOW>;
+ power-gpio = <&gpio 1 GPIO_ACTIVE_LOW>;
};
This property will make GPIOs 15, 16 and 17 available to the driver under the
struct gpio_desc *red, *green, *blue, *power;
- red = gpiod_get_index(dev, "led", 0);
- green = gpiod_get_index(dev, "led", 1);
- blue = gpiod_get_index(dev, "led", 2);
+ red = gpiod_get_index(dev, "led", 0, GPIOD_OUT_HIGH);
+ green = gpiod_get_index(dev, "led", 1, GPIOD_OUT_HIGH);
+ blue = gpiod_get_index(dev, "led", 2, GPIOD_OUT_HIGH);
- power = gpiod_get(dev, "power");
+ power = gpiod_get(dev, "power", GPIOD_OUT_HIGH);
The led GPIOs will be active-high, while the power GPIO will be active-low (i.e.
gpiod_is_active_low(power) will be true).
+The second parameter of the gpiod_get() functions, the con_id string, has to be
+the <function>-prefix of the GPIO suffixes ("gpios" or "gpio", automatically
+looked up by the gpiod functions internally) used in the device tree. With above
+"led-gpios" example, use the prefix without the "-" as con_id parameter: "led".
+
+Internally, the GPIO subsystem prefixes the GPIO suffix ("gpios" or "gpio")
+with the string passed in con_id to get the resulting string
+(snprintf(... "%s-%s", con_id, gpio_suffixes[]).
+
ACPI
----
ACPI also supports function names for GPIOs in a similar fashion to DT.
struct gpio_desc *red, *green, *blue, *power;

- power = gpiod_get(dev, "power");
- gpiod_direction_output(power, 1);
+ power = gpiod_get(dev, "power", GPIOD_OUT_HIGH);
-Since the "power" GPIO is mapped as active-low, its actual signal will be 0
-after this code. Contrary to the legacy integer GPIO interface, the active-low
-property is handled during mapping and is thus transparent to GPIO consumers.
+Since the "led" GPIOs are mapped as active-high, this example will switch their
+signals to 1, i.e. enabling the LEDs. And for the "power" GPIO, which is mapped
+as active-low, its actual signal will be 0 after this code. Contrary to the legacy
+integer GPIO interface, the active-low property is handled during mapping and is

+Description
+-----------
+
+This driver supports hardware monitoring for SoC's based on the ARM
+System Control Processor (SCP) implementing the System Control
+Processor Interface (SCPI). The following sensor types are supported
+by the SCP -
+
+ * temperature
+ * voltage
+ * current
+ * power
+
+The SCP interface provides an API to query the available sensors and
+their values which are then exported to userspace by this driver.
+
+Usage Notes
+-----------
+
+The driver relies on device tree node to indicate the presence of SCPI
+support in the kernel. See
+Documentation/devicetree/bindings/arm/arm,scpi.txt for details of the
+devicetree node.

+Virtual Routing and Forwarding (VRF)
+====================================
+The VRF device combined with ip rules provides the ability to create virtual
+routing and forwarding domains (aka VRFs, VRF-lite to be specific) in the
+Linux network stack. One use case is the multi-tenancy problem where each
+tenant has their own unique routing tables and in the very least need
+different default gateways.
+
+Processes can be "VRF aware" by binding a socket to the VRF device. Packets
+through the socket then use the routing table associated with the VRF
+device. An important feature of the VRF device implementation is that it
+impacts only Layer 3 and above so L2 tools (e.g., LLDP) are not affected
+(ie., they do not need to be run in each VRF). The design also allows
+the use of higher priority ip rules (Policy Based Routing, PBR) to take
+precedence over the VRF device rules directing specific traffic as desired.
+
+In addition, VRF devices allow VRFs to be nested within namespaces. For
+example network namespaces provide separation of network interfaces at L1
+(Layer 1 separation), VLANs on the interfaces within a namespace provide
+L2 separation and then VRF devices provide L3 separation.
+
+Design
+------
+A VRF device is created with an associated route table. Network interfaces
+are then enslaved to a VRF device:
+
+ +-----------------------------+
+ | vrf-blue | ===> route table 10
+ +-----------------------------+
+ | | |
+ +------+ +------+ +-------------+
+ | eth1 | | eth2 | ... | bond1 |
+ +------+ +------+ +-------------+
+ | |
+ +------+ +------+
+ | eth8 | | eth9 |
+ +------+ +------+
+
+Packets received on an enslaved device and are switched to the VRF device
+using an rx_handler which gives the impression that packets flow through
+the VRF device. Similarly on egress routing rules are used to send packets
+to the VRF device driver before getting sent out the actual interface. This
+allows tcpdump on a VRF device to capture all packets into and out of the
+VRF as a whole.[1] Similiarly, netfilter [2] and tc rules can be applied
+using the VRF device to specify rules that apply to the VRF domain as a whole.
+
+[1] Packets in the forwarded state do not flow through the device, so those
+ packets are not seen by tcpdump. Will revisit this limitation in a
+ future release.
+
+[2] Iptables on ingress is limited to NF_INET_PRE_ROUTING only with skb->dev
+ set to real ingress device and egress is limited to NF_INET_POST_ROUTING.
+ Will revisit this limitation in a future release.
+
+
+Setup
+-----
+1. VRF device is created with an association to a FIB table.
+ e.g, ip link add vrf-blue type vrf table 10
+ ip link set dev vrf-blue up
+
+2. Rules are added that send lookups to the associated FIB table when the
+ iif or oif is the VRF device. e.g.,
+ ip ru add oif vrf-blue table 10
+ ip ru add iif vrf-blue table 10
+
+ Set the default route for the table (and hence default route for the VRF).
+ e.g, ip route add table 10 prohibit default
+
+3. Enslave L3 interfaces to a VRF device.
+ e.g, ip link set dev eth1 master vrf-blue
+
+ Local and connected routes for enslaved devices are automatically moved to
+ the table associated with VRF device. Any additional routes depending on
+ the enslaved device will need to be reinserted following the enslavement.
+
+4. Additional VRF routes are added to associated table.
+ e.g., ip route add table 10 ...
+
+
+Applications
+------------
+Applications that are to work within a VRF need to bind their socket to the
+VRF device:
+
+ setsockopt(sd, SOL_SOCKET, SO_BINDTODEVICE, dev, strlen(dev)+1);
+
+or to specify the output device using cmsg and IP_PKTINFO.
+
+
+Limitations
+-----------
+VRF device currently only works for IPv4. Support for IPv6 is under development.
+
+Index of original ingress interface is not available via cmsg. Will address
+soon.
(alternatively, the runtime_suspend() callback will have to check if the
device should really be suspended and return -EAGAIN if that is not the case).

+The runtime PM of PCI devices is enabled by default by the PCI core. PCI
+device drivers do not need to enable it and should not attempt to do so.
+However, it is blocked by pci_pm_init() that runs the pm_runtime_forbid()
+helper function. In addition to that, the runtime PM usage counter of
+each PCI device is incremented by local_pci_probe() before executing the
+probe callback provided by the device's driver.
+
+If a PCI driver implements the runtime PM callbacks and intends to use the
+runtime PM framework provided by the PM core and the PCI subsystem, it needs
+to decrement the device's runtime PM usage counter in its probe callback
+function. If it doesn't do that, the counter will always be different from
+zero for the device and it will never be runtime-suspended. The simplest
+way to do that is by calling pm_runtime_put_noidle(), but if the driver
+wants to schedule an autosuspend right away, for example, it may call
+pm_runtime_put_autosuspend() instead for this purpose. Generally, it
+just needs to call a function that decrements the devices usage counter
+from its probe routine to make runtime PM work for the device.
+
+It is important to remember that the driver's runtime_suspend() callback
+may be executed right after the usage counter has been decremented, because
+user space may already have cuased the pm_runtime_allow() helper function
+unblocking the runtime PM of the device to run via sysfs, so the driver must
+be prepared to cope with that.
+
+The driver itself should not call pm_runtime_allow(), though. Instead, it
+should let user space or some platform-specific code do that (user space can
+do it via sysfs as stated above), but it must be prepared to handle the
runtime PM of the device correctly as soon as pm_runtime_allow() is called
-(which may happen at any time). [It also is possible that user space causes
-pm_runtime_allow() to be called via sysfs before the driver is loaded, so in
-fact the driver has to be prepared to handle the runtime PM of the device as
-soon as it calls pm_runtime_enable().]
+(which may happen at any time, even before the driver is loaded).
+
+When the driver's remove callback runs, it has to balance the decrementation
+of the device's runtime PM usage counter at the probe time. For this reason,
+if it has decremented the counter in its probe callback, it must run
+pm_runtime_get_noresume() in its remove callback. [Since the core carries
+out a runtime resume of the device and bumps up the device's usage counter
+before running the driver's remove callback, the runtime PM of the device
+is effectively disabled for the duration of the remove execution and all
+runtime PM helper functions incrementing the device's usage counter are
+then effectively equivalent to pm_runtime_get_noresume().]
The runtime PM framework works by processing requests to suspend or resume
devices, or to check if they are idle (in which cases it is reasonable to

- * Params passed in registers:

- * r1 = unlock SDRC DLL? (1 = yes, 0 = no). Only unlock DLL for
- * SDRC rates < 83MHz
- * r2 = number of MPU cycles to wait for SDRC to stabilize after
- * reprogramming the SDRC when switching to a slower MPU speed
- * r3 = increasing SDRC rate? (1 = yes, 0 = no)
- *
- * Params passed via the stack. The needed params will be copied in SRAM
- * before use by the code in SRAM (SDRAM is not accessible during SDRC
- * reconfiguration):
- * new SDRC_RFR_CTRL_0 register contents
- * new SDRC_ACTIM_CTRL_A_0 register contents
- * new SDRC_ACTIM_CTRL_B_0 register contents
- * new SDRC_MR_0 register value
- * new SDRC_RFR_CTRL_1 register contents
- * new SDRC_ACTIM_CTRL_A_1 register contents
- * new SDRC_ACTIM_CTRL_B_1 register contents
- * new SDRC_MR_1 register value
- *
- * If the param SDRC_RFR_CTRL_1 is 0, the parameters are not programmed into
- * the SDRC CS1 registers
- *
- * NOTE: This code no longer attempts to program the SDRC AC timing and MR
- * registers. This is because the code currently cannot ensure that all
- * L3 initiators (e.g., sDMA, IVA, DSS DISPC, etc.) are not accessing the
- * SDRAM when the registers are written. If the registers are changed while
- * an initiator is accessing SDRAM, memory can be corrupted and/or the SDRC
- * may enter an unpredictable state. In the future, the intent is to
- * re-enable this code in cases where we can ensure that no initiators are
- * touching the SDRAM. Until that time, users who know that their use case
- * can satisfy the above requirement can enable the CONFIG_OMAP3_SDRC_AC_TIMING
- * option.
- *
- * Richard Woodruff notes that any changes to this code must be carefully
- * audited and tested to ensure that they don't cause a TLB miss while
- * the SDRAM is inaccessible. Such a situation will crash the system
- * since it will cause the ARM MMU to attempt to walk the page tables.
- * These crashes may be intermittent.

- Allows the configuration of the timer frequency. It is customary
- to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
- case of low timer frequencies other values may be more suitable.
- Renesas ARM SoC systems using a 32768 Hz RCLK for clock events may
- want to select a HZ value such as 128 that can evenly divide RCLK.
- A HZ value that does not divide evenly may cause timer drift.

-*!
-*! FILE NAME : i2c.c
-*!
-*! DESCRIPTION: implements an interface for IIC/I2C, both directly from other
-*! kernel modules (i2c_writereg/readreg) and from userspace using
-*! ioctl()'s
-*!
-*! Nov 30 1998 Torbjorn Eliasson Initial version.
-*! Bjorn Wesen Elinux kernel version.
-*! Jan 14 2000 Johan Adolfsson Fixed PB shadow register stuff -
-*! don't use PB_I2C if DS1302 uses same bits,
-*! use PB.
-*| June 23 2003 Pieter Grimmerink Added 'i2c_sendnack'. i2c_readreg now
-*| generates nack on last received byte,
-*| instead of ack.
-*| i2c_getack changed data level while clock
-*| was high, causing DS75 to see a stop condition
-*!

+ * The RSB controller looks like an SMBus controller which only supports
+ * byte and word data transfers. But, it differs from standard SMBus
+ * protocol on several aspects:
+ * - it uses addresses set at runtime to address slaves. Runtime addresses
+ * are sent to slaves using their 12bit hardware addresses. Up to 15
+ * runtime addresses are available.
+ * - it adds a parity bit every 8bits of data and address for read and
+ * write accesses; this replaces the ack bit
+ * - only one read access is required to read a byte (instead of a write
+ * followed by a read access in standard SMBus protocol)
+ * - there's no Ack bit after each read access
+ *
+ * This means this bus cannot be used to interface with standard SMBus
+ * devices. Devices known to support this interface include the AXP223,
+ * AXP809, and AXP806 PMICs, and the AC100 audio codec, all from X-Powers.
+ *
+ * A description of the operation and wire protocol can be found in the
+ * RSB section of Allwinner's A80 user manual, which can be found at
+ *
+ * https://github.com/allwinner-zh/documents/tree/master/A80
+ *
+ * This document is officially released by Allwinner.
+ *
+ * This driver is based on i2c-sun6i-p2wi.c, the P2WI bus driver.

+/**
+ * DOC: BCM2835 CPRMAN (clock manager for the "audio" domain)
+ *
+ * The clock tree on the 2835 has several levels. There's a root
+ * oscillator running at 19.2Mhz. After the oscillator there are 5
+ * PLLs, roughly divided as "camera", "ARM", "core", "DSI displays",
+ * and "HDMI displays". Those 5 PLLs each can divide their output to
+ * produce up to 4 channels. Finally, there is the level of clocks to
+ * be consumed by other hardware components (like "H264" or "HDMI
+ * state machine"), which divide off of some subset of the PLL
+ * channels.
+ *
+ * All of the clocks in the tree are exposed in the DT, because the DT
+ * may want to make assignments of the final layer of clocks to the
+ * PLL channels, and some components of the hardware will actually
+ * skip layers of the tree (for example, the pixel clock comes
+ * directly from the PLLH PIX channel without using a CM_*CTL clock
+ * generator).

- add proper arch dependencies as needed
- audit userspace interfaces to make sure they are sane
+
+ion/
+ - Remove ION_IOC_SYNC: Flushing for devices should be purely a kernel internal
+ interface on top of dma-buf. flush_for_device needs to be added to dma-buf
+ first.
+ - Remove ION_IOC_CUSTOM: Atm used for cache flushing for cpu access in some
+ vendor trees. Should be replaced with an ioctl on the dma-buf to expose the
+ begin/end_cpu_access hooks to userspace.
+ - Clarify the tricks ion plays with explicitly managing coherency behind the
+ dma api's back (this is absolutely needed for high-perf gpu drivers): Add an
+ explicit coherency management mode to flush_for_device to be used by drivers
+ which want to manage caches themselves and which indicates whether cpu caches
+ need flushing.
+ - With those removed there's probably no use for ION_IOC_IMPORT anymore either
+ since ion would just be the central allocator for shared buffers.
+ - Add dt-binding to expose cma regions as ion heaps, with the rule that any
+ such cma regions must already be used by some device for dma. I.e. ion only
+ exposes existing cma regions and doesn't reserve unecessarily memory when
+ booting a system which doesn't use ion.

+ * this makes the compressed extent read zero out the pages
+ * belonging to the 2nd range. Imagine the following scenario:
+ *
+ * File layout

+ * [extent X, compressed length = 4K uncompressed length = 16K]
+ *
+ * If the bio to read the compressed extent covers both ranges,
+ * it will decompress extent X into the pages belonging to the
+ * first range and then it will stop, zeroing out the remaining
+ * pages that belong to the other range that points to extent X.
+ * So here we make sure we submit 2 bios, one for the first
+ * range and another one for the third range. Both will target
+ * the same physical extent from disk, but we can't currently
+ * make the compressed bio endio callback populate the pages
+ * for both ranges because each compressed bio is tightly
+ * coupled with a single extent map, and each range can have
+ * an extent map with a different offset value relative to the
+ * uncompressed data of our extent and different lengths. This

-no_force_psb This is a driver option and is not in the IA32_RTIT_CTL MSR.
-
- It stops the driver resetting the byte count to zero whenever
- enabling the trace (for example on context switches) which in
- turn results in no PSB being forced. However some processors
- will produce a PSB anyway.
-
- In any case, there is still a PSB when the trace is enabled for
- the first time.
-
- no_force_psb can be used to slightly decrease the trace size but
- may make it harder for the decoder to recover from errors.
-
- no_force_psb is not selected by default.
