Cadence DSI bridge
==================
The Cadence DSI bridge is a DPI to DSI bridge supporting up to 4 DSI lanes.
Required properties:
- compatible: should be set to "cdns,dsi".
- reg: physical base address and length of the controller's registers.
- interrupts: interrupt line connected to the DSI bridge.
- clocks: DSI bridge clocks.
- clock-names: must contain "dsi_p_clk" and "dsi_sys_clk".
- phys: phandle link to the MIPI D-PHY controller.
- phy-names: must contain "dphy".
- #address-cells: must be set to 1.
- #size-cells: must be set to 0.
Optional properties:
- resets: DSI reset lines.
- reset-names: can contain "dsi_p_rst".
Required subnodes:
- ports: Ports as described in Documentation/devicetree/bindings/graph.txt.
2 ports are available:
* port 0: this port is only needed if some of your DSI devices are
controlled through an external bus like I2C or SPI. Can have at
most 4 endpoints. The endpoint number is directly encoding the
DSI virtual channel used by this device.
* port 1: represents the DPI input.
Other ports will be added later to support the new kind of inputs.
- one subnode per DSI device connected on the DSI bus. Each DSI device should
contain a reg property encoding its virtual channel.

Allwinner A31 DSI Encoder
=========================
The DSI pipeline consists of two separate blocks: the DSI controller
itself, and its associated D-PHY.
DSI Encoder
-----------
The DSI Encoder generates the DSI signal from the TCON's.
Required properties:
- compatible: value must be one of:
* allwinner,sun6i-a31-mipi-dsi
- reg: base address and size of memory-mapped region
- interrupts: interrupt associated to this IP
- clocks: phandles to the clocks feeding the DSI encoder
* bus: the DSI interface clock
* mod: the DSI module clock
- clock-names: the clock names mentioned above
- phys: phandle to the D-PHY
- phy-names: must be "dphy"
- resets: phandle to the reset controller driving the encoder
- ports: A ports node with endpoint definitions as defined in
Documentation/devicetree/bindings/media/video-interfaces.txt. The
first port should be the input endpoint, usually coming from the
associated TCON.
Any MIPI-DSI device attached to this should be described according to
the bindings defined in ../mipi-dsi-bus.txt

This sections covers all things related to the GEM implementation in the
i915 driver.
Intel GPU Basics
----------------
An Intel GPU has multiple engines. There are several engine types.
- RCS engine is for rendering 3D and performing compute, this is named
`I915_EXEC_RENDER` in user space.
- BCS is a blitting (copy) engine, this is named `I915_EXEC_BLT` in user
space.
- VCS is a video encode and decode engine, this is named `I915_EXEC_BSD`
in user space
- VECS is video enhancement engine, this is named `I915_EXEC_VEBOX` in user
space.
- The enumeration `I915_EXEC_DEFAULT` does not refer to specific engine;
instead it is to be used by user space to specify a default rendering
engine (for 3D) that may or may not be the same as RCS.
The Intel GPU family is a family of integrated GPU's using Unified
Memory Access. For having the GPU "do work", user space will feed the
GPU batch buffers via one of the ioctls `DRM_IOCTL_I915_GEM_EXECBUFFER2`
or `DRM_IOCTL_I915_GEM_EXECBUFFER2_WR`. Most such batchbuffers will
instruct the GPU to perform work (for example rendering) and that work
needs memory from which to read and memory to which to write. All memory
is encapsulated within GEM buffer objects (usually created with the ioctl
`DRM_IOCTL_I915_GEM_CREATE`). An ioctl providing a batchbuffer for the GPU
to create will also list all GEM buffer objects that the batchbuffer reads
and/or writes. For implementation details of memory management see
`GEM BO Management Implementation Details`_.
The i915 driver allows user space to create a context via the ioctl
`DRM_IOCTL_I915_GEM_CONTEXT_CREATE` which is identified by a 32-bit
integer. Such a context should be viewed by user-space as -loosely-
analogous to the idea of a CPU process of an operating system. The i915
driver guarantees that commands issued to a fixed context are to be
executed so that writes of a previously issued command are seen by
reads of following commands. Actions issued between different contexts
(even if from the same file descriptor) are NOT given that guarantee
and the only way to synchronize across contexts (even from the same
file descriptor) is through the use of fences. At least as far back as
Gen4, also have that a context carries with it a GPU HW context;
the HW context is essentially (most of atleast) the state of a GPU.
In addition to the ordering guarantees, the kernel will restore GPU
state via HW context when commands are issued to a context, this saves
user space the need to restore (most of atleast) the GPU state at the
start of each batchbuffer. The non-deprecated ioctls to submit batchbuffer
work can pass that ID (in the lower bits of drm_i915_gem_execbuffer2::rsvd1)
to identify what context to use with the command.
The GPU has its own memory management and address space. The kernel
driver maintains the memory translation table for the GPU. For older
GPUs (i.e. those before Gen8), there is a single global such translation
table, a global Graphics Translation Table (GTT). For newer generation
GPUs each context has its own translation table, called Per-Process
Graphics Translation Table (PPGTT). Of important note, is that although
PPGTT is named per-process it is actually per context. When user space
submits a batchbuffer, the kernel walks the list of GEM buffer objects
used by the batchbuffer and guarantees that not only is the memory of
each such GEM buffer object resident but it is also present in the
(PP)GTT. If the GEM buffer object is not yet placed in the (PP)GTT,
then it is given an address. Two consequences of this are: the kernel
needs to edit the batchbuffer submitted to write the correct value of
the GPU address when a GEM BO is assigned a GPU address and the kernel
might evict a different GEM BO from the (PP)GTT to make address room
for another GEM BO. Consequently, the ioctls submitting a batchbuffer
for execution also include a list of all locations within buffers that
refer to GPU-addresses so that the kernel can edit the buffer correctly.
This process is dubbed relocation.

Clean up mmap forwarding
------------------------
A lot of drivers forward gem mmap calls to dma-buf mmap for imported buffers.
And also a lot of them forward dma-buf mmap to the gem mmap implementations.
Would be great to refactor this all into a set of small common helpers.
Contact: Daniel Vetter
Put a reservation_object into drm_gem_object
--------------------------------------------
This would remove the need for the ->gem_prime_res_obj callback. It would also
allow us to implement generic helpers for waiting for a bo, allowing for quite a
bit of refactoring in the various wait ioctl implementations.

* DOC: pp_power_profile_mode

* The amdgpu driver provides a sysfs API for adjusting the heuristics

* pp_power_profile_mode is used for this.
*
* Reading this file outputs a list of all of the predefined power profiles
* and the relevant heuristics settings for that profile.
*
* To select a profile or create a custom profile, first select manual using
* power_dpm_force_performance_level. Writing the number of a predefined
* profile to pp_power_profile_mode will enable those heuristics. To
* create a custom set of heuristics, write a string of numbers to the file
* starting with the number of the custom profile along with a setting
* for each heuristic parameter. Due to differences across asic families
* the heuristic parameters vary from family to family.
