AMDGPU - Display Contributions
|
||||
==============================
|
||||
|
||||
First of all, if you are here, you probably want to give some technical
|
||||
contribution to the display code, and for that, we say thank you :)
|
||||
|
||||
This page summarizes some of the issues you can help with; keep in mind that
|
||||
this is a static page, and it is always a good idea to try to reach developers
|
||||
in the amdgfx or some of the maintainers. Finally, this page follows the DRM
|
||||
way of creating a TODO list; for more information, check
|
||||
'Documentation/gpu/todo.rst'.
|
||||
|
||||
Gitlab issues
|
||||
=============
|
||||
|
||||
Users can report issues associated with AMD GPUs at:
|
||||
|
||||
- https://gitlab.freedesktop.org/drm/amd
|
||||
|
||||
Usually, we try to add a proper label to all new tickets to make it easy to
|
||||
filter issues. If you can reproduce any problem, you could help by adding more
|
||||
information or fixing the issue.

IGT
|
||||
===
|
||||
|
||||
`IGT`_ provides many integration tests that can be run on your GPU. We always
|
||||
want to pass a large set of tests to increase the test coverage in our CI. If
|
||||
you wish to contribute to the display code but are unsure where a good place
|
||||
is, we recommend you run all IGT tests and try to fix any failure you see in
|
||||
your hardware. Keep in mind that this failure can be an IGT problem or a kernel
|
||||
issue; it is necessary to analyze case-by-case.

Fix compilation warnings
|

Fix compilation issues when using um architecture
|
||||
-------------------------------------------------
|
||||
|
||||
Linux has a User-mode Linux (UML) feature, and the kernel can be compiled to
|
||||
the **um** architecture. Compiling for **um** can bring multiple advantages
|
||||
from the test perspective. We currently have some compilation issues in this
|
||||
area that we need to fix.

Code Refactor
|
||||
=============
|
||||
|
||||
Add prefix to DC functions to improve the debug with ftrace
|
||||
-----------------------------------------------------------
|
||||
|
||||
The Ftrace debug feature (check 'Documentation/trace/ftrace.rst') is a
|
||||
fantastic way to check the code path when developers try to make sense of a
|
||||
bug. Ftrace provides a filter mechanism that can be useful when the developer
|
||||
has some hunch of which part of the code can cause the issue; for this reason,
|
||||
if a set of functions has a proper prefix, it becomes easy to create a good
|
||||
filter. Additionally, prefixes can improve stack trace readability.
|
||||
|
||||
The DC code does not follow some prefix rules, which makes the Ftrace filter
|
||||
more complicated and reduces the readability of the stack trace. If you want
|
||||
something simple to start contributing to the display, you can make patches for
|
||||
adding prefixes to DC functions. To create those prefixes, use part of the file
|
||||
name as a prefix for all functions in the target file. Check the
|
||||
'amdgpu_dm_crtc.c` and `amdgpu_dm_plane.c` for some references. However, we
|
||||
strongly advise not to send huge patches changing these prefixes; otherwise, it
|
||||
will be hard to review and test, which can generate second thoughts from
|
||||
maintainers. Try small steps; in case of double, you can ask before you put in
|
||||
effort. We recommend first looking at folders like dceXYZ, dcnXYZ, basics,
|
||||
bios, core, clk_mgr, hwss, resource, and irq.

||||

|
||||
|
||||
Reduce code duplication
|
||||
-----------------------
|
||||
|
||||
AMD has an extensive portfolio with various dGPUs and APUs that amdgpu
|
||||
supports. To maintain the new hardware release cadence, DCE/DCN was designed in
|
||||
a modular design, making the bring-up for new hardware fast. Over the years,
|
||||
amdgpu accumulated some technical debt in the code duplication area. For this
|
||||
task, it would be a good idea to find a tool that can discover code duplication
|
||||
(including patterns) and use it as guidance to reduce duplications.
|
||||
|
||||
Level: Intermediate
|
||||
|
||||
Make atomic_commit_[check|tail] more readable
|
||||
---------------------------------------------
|
||||
|
||||
The functions responsible for atomic commit and tail are intricate and
|
||||
extensive. In particular `amdgpu_dm_atomic_commit_tail` is a long function and
|
||||
could benefit from being split into smaller helpers. Improvements in this area
|
||||
are more than welcome, but keep in mind that changes in this area will affect
|
||||
all ASICs, meaning that refactoring requires a comprehensive verification; in
|
||||
other words, this effort can take some time for validation.

=============
|
||||
|
||||
Expand kernel-doc
|
||||
-----------------
|
||||
|
||||
Many DC functions do not have a proper kernel-doc; understanding a function and
|
||||
adding documentation is a great way to learn more about the amdgpu driver and
|
||||
also leave an outstanding contribution to the entire community.

Beyond AMDGPU
|
||||
=============
|
||||
|
||||
AMDGPU provides features that are not yet enabled in the userspace. This
|
||||
section highlights some of the coolest display features, which could be enabled
|
||||
with the userspace developer helper.
|
||||
|
||||
Enable underlay
|
||||
---------------
|
||||
|
||||
AMD display has this feature called underlay (which you can read more about at
|
||||
'Documentation/GPU/amdgpu/display/mpo-overview.rst') which is intended to
|
||||
save power when playing a video. The basic idea is to put a video in the
|
||||
underlay plane at the bottom and the desktop in the plane above it with a hole
|
||||
in the video area. This feature is enabled in ChromeOS, and from our data
|
||||
measurement, it can save power.
|
||||
|
||||
Level: Unknown
|
||||
|
||||
Adaptive Backlight Modulation (ABM)
|
||||
-----------------------------------
|
||||
|
||||
ABM is a feature that adjusts the display panel's backlight level and pixel
|
||||
values depending on the displayed image. This power-saving feature can be very
|
||||
useful when the system starts to run off battery; since this will impact the
|
||||
display output fidelity, it would be good if this option was something that
|
||||
users could turn on or off.

HDR & Color management & VRR
|
||||
----------------------------

||||
|
||||
HDR, Color Management, and VRR are huge topics and it's hard to put these into
|
||||
concise ToDos. If you are interested in this topic, we recommend checking some
|
||||
blog posts from the community developers to better understand some of the
|
||||
specific challenges and people working on the subject. If anyone wants to work
|
||||
on some particular part, we can try to help with some basic guidance. Finally,
|
||||
keep in mind that we already have some kernel-doc in place for those areas.

|

DC Code validation
|
||||
------------------
|
||||
|
||||
Maintaining the same code base across multiple OSes requires a lot of
|
||||
synchronization effort between repositories and exhaustive validation. In the
|
||||
DC case, we maintain a tree to centralize code from different parts. The shared
|
||||
repository has integration tests with our Internal Linux CI farm, and we run a
|
||||
comprehensive set of IGT tests in various AMD GPUs/APUs (mostly recent dGPUs
|
||||
and APUs). Our CI also checks ARM64/32, PPC64/32, and x86_64/32 compilation
|
||||
with DCN enabled and disabled.
|
||||
|
||||
When we upstream a new feature or some patches, we pack them in a patchset with
|
||||
the prefix **DC Patches for <DATE>**, which is created based on the latest
|
||||
`amd-staging-drm-next <https://gitlab.freedesktop.org/agd5f/linux>`_. All of
|
||||
those patches are under a DC version tested as follows:
|
||||
|
||||
* Ensure that every patch compiles and the entire series pass our set of IGT
|
||||
test in different hardware.
|
||||
* Prepare a branch with those patches for our validation team. If there is an
|
||||
error, a developer will debug as fast as possible; usually, a simple bisect
|
||||
in the series is enough to point to a bad change, and two possible actions
|
||||
emerge: fix the issue or drop the patch. If it is not an easy fix, the bad
|
||||
patch is dropped.
|
||||
* Finally, developers wait a few days for community feedback before we merge
|
||||
the series.
|
||||
|
||||
It is good to stress that the test phase is something that we take extremely
|
||||
seriously, and we never merge anything that fails our validation. Follows an
|
||||
overview of our test set:
|
||||
|
||||
#. Manual test
|
||||
* Multiple Hotplugs with DP and HDMI.
|
||||
* Stress test with multiple display configuration changes via the user interface.
|
||||
* Validate VRR behaviour.
|
||||
* Check PSR.
|
||||
* Validate MPO when playing video.
|
||||
* Test more than two displays connected at the same time.
|
||||
* Check suspend/resume.
|
||||
* Validate FPO.
|
||||
* Check MST.
|
||||
#. Automated test
|
||||
* IGT tests in a farm with GPUs and APUs that support DCN and DCE.
|
||||
* Compilation validation with the latest GCC and Clang from LTS distro.
|
||||
* Cross-compilation for PowerPC 64/32, ARM 64/32, and x86 32.
|
||||
|
||||
In terms of test setup for CI and manual tests, we usually use:
|
||||
|
||||
#. The latest Ubuntu LTS.
|
||||
#. In terms of userspace, we only use fully updated open-source components
|
||||
provided by the distribution official package manager.
|
||||
#. Regarding IGT, we use the latest code from the upstream.
|
||||
#. Most of the manual tests are conducted in the GNome but we also use KDE.
|
||||
|
||||
Notice that someone from our test team will always reply to the cover letter
|
||||
with the test report.

GPU memory (also called VRAM, FrameBuffer, etc.) to a display. In other words,
|
||||
it would:
|
||||
|
||||
1. Read frame information from memory;
|
||||
2. Perform required transformation;
|
||||
3. Send pixel data to sink devices.

Xe – Merge Acceptance Plan
|
||||
==========================
|
||||
Xe is a new driver for Intel GPUs that supports both integrated and
|
||||
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).
|
||||
|
||||
This document aims to establish a merge plan for the Xe, by writing down clear
|
||||
pre-merge goals, in order to avoid unnecessary delays.
|
||||
|
||||
Xe – Overview
|
||||
=============
|
||||
The main motivation of Xe is to have a fresh base to work from that is
|
||||
unencumbered by older platforms, whilst also taking the opportunity to
|
||||
rearchitect our driver to increase sharing across the drm subsystem, both
|
||||
leveraging and allowing us to contribute more towards other shared components
|
||||
like TTM and drm/scheduler.
|
||||
|
||||
This is also an opportunity to start from the beginning with a clean uAPI that is
|
||||
extensible by design and already aligned with the modern userspace needs. For
|
||||
this reason, the memory model is solely based on GPU Virtual Address space
|
||||
bind/unbind (‘VM_BIND’) of GEM buffer objects (BOs) and execution only supporting
|
||||
explicit synchronization. With persistent mapping across the execution, the
|
||||
userspace does not need to provide a list of all required mappings during each
|
||||
submission.
|
||||
|
||||
The new driver leverages a lot from i915. As for display, the intent is to share
|
||||
the display code with the i915 driver so that there is maximum reuse there.
|
||||
|
||||
As for the power management area, the goal is to have a much-simplified support
|
||||
for the system suspend states (S-states), PCI device suspend states (D-states),
|
||||
GPU/Render suspend states (R-states) and frequency management. It should leverage
|
||||
as much as possible all the existent PCI-subsystem infrastructure (pm and
|
||||
runtime_pm) and underlying firmware components such PCODE and GuC for the power
|
||||
states and frequency decisions.

Xe – Platforms
|
||||
==============
|
||||
Currently, Xe is already functional and has experimental support for multiple
|
||||
platforms starting from Tiger Lake, with initial support in userspace implemented
|
||||
in Mesa (for Iris and Anv, our OpenGL and Vulkan drivers), as well as in NEO
|
||||
(for OpenCL and Level0).
|
||||
|
||||
During a transition period, platforms will be supported by both Xe and i915.
|
||||
However, the force_probe mechanism existent in both drivers will allow only one
|
||||
official and by-default probe at a given time.
|
||||
|
||||
For instance, in order to probe a DG2 which PCI ID is 0x5690 by Xe instead of
|
||||
i915, the following set of parameters need to be used:
|
||||
|
||||
```
|
||||
i915.force_probe=!5690 xe.force_probe=5690
|
||||
```
|
||||
|
||||
In both drivers, the ‘.require_force_probe’ protection forces the user to use the
|
||||
force_probe parameter while the driver is under development. This protection is
|
||||
only removed when the support for the platform and the uAPI are stable. Stability
|
||||
which needs to be demonstrated by CI results.
|
||||
|
||||
In order to avoid user space regressions, i915 will continue to support all the
|
||||
current platforms that are already out of this protection. Xe support will be
|
||||
forever experimental and dependent on the usage of force_probe for these
|
||||
platforms.
|
||||
|
||||
When the time comes for Xe, the protection will be lifted on Xe and kept in i915.
|
||||
|
||||
Xe – Pre-Merge Goals - Work-in-Progress
|
||||
=======================================
|
||||
|
||||
Display integration with i915
|
||||
-----------------------------
|
||||
In order to share the display code with the i915 driver so that there is maximum
|
||||
reuse, the i915/display/ code is built twice, once for i915.ko and then for
|
||||
xe.ko. Currently, the i915/display code in Xe tree is polluted with many 'ifdefs'
|
||||
depending on the build target. The goal is to refactor both Xe and i915/display
|
||||
code simultaneously in order to get a clean result before they land upstream, so
|
||||
that display can already be part of the initial pull request towards drm-next.
|
||||
|
||||
However, display code should not gate the acceptance of Xe in upstream. Xe
|
||||
patches will be refactored in a way that display code can be removed, if needed,
|
||||
from the first pull request of Xe towards drm-next. The expectation is that when
|
||||
both drivers are part of the drm-tip, the introduction of cleaner patches will be
|
||||
easier and speed up.
|
||||
|
||||
Xe – uAPI high level overview
|
||||
=============================
|
||||
|
||||
...Warning: To be done in follow up patches after/when/where the main consensus in various items are individually reached.
|
||||
|
||||
Xe – Pre-Merge Goals - Completed
|
||||
================================
|
||||
|
||||
Drm_exec
|
||||
--------
|
||||
Helper to make dma_resv locking for a big number of buffers is getting removed in
|
||||
the drm_exec series proposed in https://patchwork.freedesktop.org/patch/524376/
|
||||
If that happens, Xe needs to change and incorporate the changes in the driver.
|
||||
The goal is to engage with the Community to understand if the best approach is to
|
||||
move that to the drivers that are using it or if we should keep the helpers in
|
||||
place waiting for Xe to get merged.
|
||||
|
||||
This item ties into the GPUVA, VM_BIND, and even long-running compute support.
|
||||
|
||||
As a key measurable result, we need to have a community consensus documented in
|
||||
this document and the Xe driver prepared for the changes, if necessary.
|
||||
|
||||
Userptr integration and vm_bind
|
||||
-------------------------------
|
||||
Different drivers implement different ways of dealing with execution of userptr.
|
||||
With multiple drivers currently introducing support to VM_BIND, the goal is to
|
||||
aim for a DRM consensus on what’s the best way to have that support. To some
|
||||
extent this is already getting addressed itself with the GPUVA where likely the
|
||||
userptr will be a GPUVA with a NULL GEM call VM bind directly on the userptr.
|
||||
However, there are more aspects around the rules for that and the usage of
|
||||
mmu_notifiers, locking and other aspects.
|
||||
|
||||
This task here has the goal of introducing a documentation of the basic rules.
|
||||
|
||||
The documentation *needs* to first live in this document (API session below) and
|
||||
then moved to another more specific document or at Xe level or at DRM level.
|
||||
|
||||
Documentation should include:
|
||||
|
||||
* The userptr part of the VM_BIND api.
|
||||
|
||||
* Locking, including the page-faulting case.
|
||||
|
||||
* O(1) complexity under VM_BIND.
|
||||
|
||||
The document is now included in the drm documentation :doc:`here </gpu/drm-vm-bind-async>`.
|
||||
|
||||
Some parts of userptr like mmu_notifiers should become GPUVA or DRM helpers when
|
||||
the second driver supporting VM_BIND+userptr appears. Details to be defined when
|
||||
the time comes.
|
||||
|
||||
The DRM GPUVM helpers do not yet include the userptr parts, but discussions
|
||||
about implementing them are ongoing.
|
||||
|
||||
ASYNC VM_BIND
|
||||
-------------
|
||||
Although having a common DRM level IOCTL for VM_BIND is not a requirement to get
|
||||
Xe merged, it is mandatory to have a consensus with other drivers and Mesa.
|
||||
It needs to be clear how to handle async VM_BIND and interactions with userspace
|
||||
memory fences. Ideally with helper support so people don't get it wrong in all
|
||||
possible ways.
|
||||
|
||||
As a key measurable result, the benefits of ASYNC VM_BIND and a discussion of
|
||||
various flavors, error handling and sample API suggestions are documented in
|
||||
:doc:`The ASYNC VM_BIND document </gpu/drm-vm-bind-async>`.
|
||||
|
||||
Drm_scheduler
|
||||
-------------
|
||||
Xe primarily uses Firmware based scheduling (GuC FW). However, it will use
|
||||
drm_scheduler as the scheduler ‘frontend’ for userspace submission in order to
|
||||
resolve syncobj and dma-buf implicit sync dependencies. However, drm_scheduler is
|
||||
not yet prepared to handle the 1-to-1 relationship between drm_gpu_scheduler and
|
||||
drm_sched_entity.
|
||||
|
||||
Deeper changes to drm_scheduler should *not* be required to get Xe accepted, but
|
||||
some consensus needs to be reached between Xe and other community drivers that
|
||||
could also benefit from this work, for coupling FW based/assisted submission such
|
||||
as the ARM’s new Mali GPU driver, and others.
|
||||
|
||||
As a key measurable result, the patch series introducing Xe itself shall not
|
||||
depend on any other patch touching drm_scheduler itself that was not yet merged
|
||||
through drm-misc. This, by itself, already includes the reach of an agreement for
|
||||
uniform 1 to 1 relationship implementation / usage across drivers.
|
||||
|
||||
Long running compute: minimal data structure/scaffolding
|
||||
--------------------------------------------------------
|
||||
The generic scheduler code needs to include the handling of endless compute
|
||||
contexts, with the minimal scaffolding for preempt-ctx fences (probably on the
|
||||
drm_sched_entity) and making sure drm_scheduler can cope with the lack of job
|
||||
completion fence.
|
||||
|
||||
The goal is to achieve a consensus ahead of Xe initial pull-request, ideally with
|
||||
this minimal drm/scheduler work, if needed, merged to drm-misc in a way that any
|
||||
drm driver, including Xe, could re-use and add their own individual needs on top
|
||||
in a next stage. However, this should not block the initial merge.
|
||||
|
||||
Dev_coredump
|
||||
------------
|
||||
|
||||
Xe needs to align with other drivers on the way that the error states are
|
||||
dumped, avoiding a Xe only error_state solution. The goal is to use devcoredump
|
||||
infrastructure to report error states, since it produces a standardized way
|
||||
by exposing a virtual and temporary /sys/class/devcoredump device.
|
||||
|
||||
As the key measurable result, Xe driver needs to provide GPU snapshots captured
|
||||
at hang time through devcoredump, but without depending on any core modification
|
||||
of devcoredump infrastructure itself.
|
||||
|
||||
Later, when we are in-tree, the goal is to collaborate with devcoredump
|
||||
infrastructure with overall possible improvements, like multiple file support
|
||||
for better organization of the dumps, snapshot support, dmesg extra print,
|
||||
and whatever may make sense and help the overall infrastructure.
|
||||
|
||||
DRM_VM_BIND
|
||||
-----------
|
||||
Nouveau, and Xe are all implementing ‘VM_BIND’ and new ‘Exec’ uAPIs in order to
|
||||
fulfill the needs of the modern uAPI. Xe merge should *not* be blocked on the
|
||||
development of a common new drm_infrastructure. However, the Xe team needs to
|
||||
engage with the community to explore the options of a common API.
|
||||
|
||||
As a key measurable result, the DRM_VM_BIND needs to be documented in this file
|
||||
below, or this entire block deleted if the consensus is for independent drivers
|
||||
vm_bind ioctls.
|
||||
|
||||
Although having a common DRM level IOCTL for VM_BIND is not a requirement to get
|
||||
Xe merged, it is mandatory to enforce the overall locking scheme for all major
|
||||
structs and list (so vm and vma). So, a consensus is needed, and possibly some
|
||||
common helpers. If helpers are needed, they should be also documented in this
|
||||
document.
|
||||
|
||||
GPU VA
|
||||
------
|
||||
Two main goals of Xe are meeting together here:
|
||||
|
||||
1) Have an uAPI that aligns with modern UMD needs.
|
||||
|
||||
2) Early upstream engagement.
|
||||
|
||||
RedHat engineers working on Nouveau proposed a new DRM feature to handle keeping
|
||||
track of GPU virtual address mappings. This is still not merged upstream, but
|
||||
this aligns very well with our goals and with our VM_BIND. The engagement with
|
||||
upstream and the port of Xe towards GPUVA is already ongoing.
|
||||
|
||||
As a key measurable result, Xe needs to be aligned with the GPU VA and working in
|
||||
our tree. Missing Nouveau patches should *not* block Xe and any needed GPUVA
|
||||
related patch should be independent and present on dri-devel or acked by
|
||||
maintainers to go along with the first Xe pull request towards drm-next.

Rename drm_atomic_state
|
||||
-----------------------
|
||||
|
||||
The KMS framework uses two slightly different definitions for the ``state``
|
||||
concept. For a given object (plane, CRTC, encoder, etc., so
|
||||
``drm_$OBJECT_state``), the state is the entire state of that object. However,
|
||||
at the device level, ``drm_atomic_state`` refers to a state update for a
|
||||
limited number of objects.
|
||||
|
||||
The state isn't the entire device state, but only the full state of some
|
||||
objects in that device. This is confusing to newcomers, and
|
||||
``drm_atomic_state`` should be renamed to something clearer like
|
||||
``drm_atomic_commit``.
|
||||
|
||||
In addition to renaming the structure itself, it would also imply renaming some
|
||||
related functions (``drm_atomic_state_alloc``, ``drm_atomic_state_get``,
|
||||
``drm_atomic_state_put``, ``drm_atomic_state_init``,
|
||||
``__drm_atomic_state_free``, etc.).
