drm/amd/display - Display Core (DC)
|
||||
===================================
|
||||
|
||||
*placeholder - general description of supported platforms, what dc is, etc.*
|
||||
|
||||
Because it is partially shared with other operating systems, the Display Core
|
||||
Driver is divided in two pieces.
|
||||
|
||||
1. **Display Core (DC)** contains the OS-agnostic components. Things like
|
||||
hardware programming and resource management are handled here.
|
||||
2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
|
||||
amdgpu base driver and DRM are implemented here.
|
||||
|
||||
It doesn't help that the entire package is frequently referred to as DC. But
|
||||
with the context in mind, it should be clear.
|
||||
|
||||
When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
|
||||
supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
|
||||
Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
|
||||
|
||||
To determine if DC is loaded, search dmesg for the following entry:
|
||||
|
||||
``Display Core initialized with <version number here>``

||||

The AMDGPU RAS interfaces are exposed via sysfs (for informational queries) and
|
||||
debugfs (for error injection).

Sample Code
|
||||
-----------
|
||||
Sample code for testing error injection can be found here:
|
||||
https://cgit.freedesktop.org/mesa/drm/tree/tests/amdgpu/ras_tests.c
|
||||
|
||||
This is part of the libdrm amdgpu unit tests which cover several areas of the GPU.
|
||||
There are four sets of tests:
|
||||
|
||||
RAS Basic Test
|
||||
|
||||
The test verifies the RAS feature enabled status and makes sure the necessary sysfs and debugfs files
|
||||
are present.
|
||||
|
||||
RAS Query Test
|
||||
|
||||
This test checks the RAS availability and enablement status for each supported IP block as well as
|
||||
the error counts.
|
||||
|
||||
RAS Inject Test
|
||||
|
||||
This test injects errors for each IP.
|
||||
|
||||
RAS Disable Test
|
||||
|
||||
This test tests disabling of RAS features for each IP block.

||||

DC Visual Confirmation
|
||||
======================
|
||||
|
||||
Display core provides a feature named visual confirmation, which is a set of
|
||||
bars added at the scanout time by the driver to convey some specific
|
||||
information. In general, you can enable this debug option by using::
|
||||
|
||||
echo <N> > /sys/kernel/debug/dri/0/amdgpu_dm_visual_confirm
|
||||
|
||||
Where `N` is an integer number for some specific scenarios that the developer
|
||||
wants to enable, you will see some of these debug cases in the following
|
||||
subsection.
|
||||
|
||||
Multiple Planes Debug
|
||||
---------------------
|
||||
|
||||
If you want to enable or debug multiple planes in a specific user-space
|
||||
application, you can leverage a debug feature named visual confirm. For
|
||||
enabling it, you will need::
|
||||
|
||||
echo 1 > /sys/kernel/debug/dri/0/amdgpu_dm_visual_confirm
|
||||
|
||||
You need to reload your GUI to see the visual confirmation. When the plane
|
||||
configuration changes or a full update occurs there will be a colored bar at
|
||||
the bottom of each hardware plane being drawn on the screen.
|
||||
|
||||
* The color indicates the format - For example, red is AR24 and green is NV12
|
||||
* The height of the bar indicates the index of the plane
|
||||
* Pipe split can be observed if there are two bars with a difference in height
|
||||
covering the same plane
|
||||
|
||||
Consider the video playback case in which a video is played in a specific
|
||||
plane, and the desktop is drawn in another plane. The video plane should
|
||||
feature one or two green bars at the bottom of the video depending on pipe
|
||||
split configuration.
|
||||
|
||||
* There should **not** be any visual corruption
|
||||
* There should **not** be any underflow or screen flashes
|
||||
* There should **not** be any black screens
|
||||
* There should **not** be any cursor corruption
|
||||
* Multiple plane **may** be briefly disabled during window transitions or
|
||||
resizing but should come back after the action has finished
|
||||
|
||||
Pipe Split Debug
|
||||
----------------
|
||||
|
||||
Sometimes we need to debug if DCN is splitting pipes correctly, and visual
|
||||
confirmation is also handy for this case. Similar to the MPO case, you can use
|
||||
the below command to enable visual confirmation::
|
||||
|
||||
echo 1 > /sys/kernel/debug/dri/0/amdgpu_dm_visual_confirm
|
||||
|
||||
In this case, if you have a pipe split, you will see one small red bar at the
|
||||
bottom of the display covering the entire display width and another bar
|
||||
covering the second pipe. In other words, you will see a bit high bar in the
|
||||
second pipe.
|
||||
|
||||
DTN Debug
|
||||
=========
|
||||
|
||||
DC (DCN) provides an extensive log that dumps multiple details from our
|
||||
hardware configuration. Via debugfs, you can capture those status values by
|
||||
using Display Test Next (DTN) log, which can be captured via debugfs by using::
|
||||
|
||||
cat /sys/kernel/debug/dri/0/amdgpu_dm_dtn_log
|
||||
|
||||
Since this log is updated accordingly with DCN status, you can also follow the
|
||||
change in real-time by using something like::
|
||||
|
||||
sudo watch -d cat /sys/kernel/debug/dri/0/amdgpu_dm_dtn_log
|
||||
|
||||
When reporting a bug related to DC, consider attaching this log before and
|
||||
after you reproduce the bug.

Display Core Next (DCN)
|
||||
=======================
|
||||
|
||||
To equip our readers with the basic knowledge of how AMD Display Core Next
|
||||
(DCN) works, we need to start with an overview of the hardware pipeline. Below
|
||||
you can see a picture that provides a DCN overview, keep in mind that this is a
|
||||
generic diagram, and we have variations per ASIC.
|
||||
|
||||
.. kernel-figure:: dc_pipeline_overview.svg
|
||||
|
||||
Based on this diagram, we can pass through each block and briefly describe
|
||||
them:
|
||||
|
||||
* **Display Controller Hub (DCHUB)**: This is the gateway between the Scalable
|
||||
Data Port (SDP) and DCN. This component has multiple features, such as memory
|
||||
arbitration, rotation, and cursor manipulation.
|
||||
|
||||
* **Display Pipe and Plane (DPP)**: This block provides pre-blend pixel
|
||||
processing such as color space conversion, linearization of pixel data, tone
|
||||
mapping, and gamut mapping.
|
||||
|
||||
* **Multiple Pipe/Plane Combined (MPC)**: This component performs blending of
|
||||
multiple planes, using global or per-pixel alpha.
|
||||
|
||||
* **Output Pixel Processing (OPP)**: Process and format pixels to be sent to
|
||||
the display.
|
||||
|
||||
* **Output Pipe Timing Combiner (OPTC)**: It generates time output to combine
|
||||
streams or divide capabilities. CRC values are generated in this block.
|
||||
|
||||
* **Display Output (DIO)**: Codify the output to the display connected to our
|
||||
GPU.
|
||||
|
||||
* **Display Writeback (DWB)**: It provides the ability to write the output of
|
||||
the display pipe back to memory as video frames.
|
||||
|
||||
* **Multi-Media HUB (MMHUBBUB)**: Memory controller interface for DMCUB and DWB
|
||||
(Note that DWB is not hooked yet).
|
||||
|
||||
* **DCN Management Unit (DMU)**: It provides registers with access control and
|
||||
interrupts the controller to the SOC host interrupt unit. This block includes
|
||||
the Display Micro-Controller Unit - version B (DMCUB), which is handled via
|
||||
firmware.
|
||||
|
||||
* **DCN Clock Generator Block (DCCG)**: It provides the clocks and resets
|
||||
for all of the display controller clock domains.
|
||||
|
||||
* **Azalia (AZ)**: Audio engine.
|
||||
|
||||
The above diagram is an architecture generalization of DCN, which means that
|
||||
every ASIC has variations around this base model. Notice that the display
|
||||
pipeline is connected to the Scalable Data Port (SDP) via DCHUB; you can see
|
||||
the SDP as the element from our Data Fabric that feeds the display pipe.
|
||||
|
||||
Always approach the DCN architecture as something flexible that can be
|
||||
configured and reconfigured in multiple ways; in other words, each block can be
|
||||
setup or ignored accordingly with userspace demands. For example, if we
|
||||
want to drive an 8k@60Hz with a DSC enabled, our DCN may require 4 DPP and 2
|
||||
OPP. It is DC's responsibility to drive the best configuration for each
|
||||
specific scenario. Orchestrate all of these components together requires a
|
||||
sophisticated communication interface which is highlighted in the diagram by
|
||||
the edges that connect each block; from the chart, each connection between
|
||||
these blocks represents:
|
||||
|
||||
1. Pixel data interface (red): Represents the pixel data flow;
|
||||
2. Global sync signals (green): It is a set of synchronization signals composed
|
||||
by VStartup, VUpdate, and VReady;
|
||||
3. Config interface: Responsible to configure blocks;
|
||||
4. Sideband signals: All other signals that do not fit the previous one.
|
||||
|
||||
These signals are essential and play an important role in DCN. Nevertheless,
|
||||
the Global Sync deserves an extra level of detail described in the next
|
||||
section.
|
||||
|
||||
All of these components are represented by a data structure named dc_state.
|
||||
From DCHUB to MPC, we have a representation called dc_plane; from MPC to OPTC,
|
||||
we have dc_stream, and the output (DIO) is handled by dc_link. Keep in mind
|
||||
that HUBP accesses a surface using a specific format read from memory, and our
|
||||
dc_plane should work to convert all pixels in the plane to something that can
|
||||
be sent to the display via dc_stream and dc_link.
|
||||
|
||||
Front End and Back End
|
||||
----------------------
|
||||
|
||||
Display pipeline can be broken down into two components that are usually
|
||||
referred as **Front End (FE)** and **Back End (BE)**, where FE consists of:
|
||||
|
||||
* DCHUB (Mainly referring to a subcomponent named HUBP)
|
||||
* DPP
|
||||
* MPC
|
||||
|
||||
On the other hand, BE consist of
|
||||
|
||||
* OPP
|
||||
* OPTC
|
||||
* DIO (DP/HDMI stream encoder and link encoder)
|
||||
|
||||
OPP and OPTC are two joining blocks between FE and BE. On a side note, this is
|
||||
a one-to-one mapping of the link encoder to PHY, but we can configure the DCN
|
||||
to choose which link encoder to connect to which PHY. FE's main responsibility
|
||||
is to change, blend and compose pixel data, while BE's job is to frame a
|
||||
generic pixel stream to a specific display's pixel stream.
|
||||
|
||||
Data Flow
|
||||
---------
|
||||
|
||||
Initially, data is passed in from VRAM through Data Fabric (DF) in native pixel
|
||||
formats. Such data format stays through till HUBP in DCHUB, where HUBP unpacks
|
||||
different pixel formats and outputs them to DPP in uniform streams through 4
|
||||
channels (1 for alpha + 3 for colors).
|
||||
|
||||
The Converter and Cursor (CNVC) in DPP would then normalize the data
|
||||
representation and convert them to a DCN specific floating-point format (i.e.,
|
||||
different from the IEEE floating-point format). In the process, CNVC also
|
||||
applies a degamma function to transform the data from non-linear to linear
|
||||
space to relax the floating-point calculations following. Data would stay in
|
||||
this floating-point format from DPP to OPP.
|
||||
|
||||
Starting OPP, because color transformation and blending have been completed
|
||||
(i.e alpha can be dropped), and the end sinks do not require the precision and
|
||||
dynamic range that floating points provide (i.e. all displays are in integer
|
||||
depth format), bit-depth reduction/dithering would kick in. In OPP, we would
|
||||
also apply a regamma function to introduce the gamma removed earlier back.
|
||||
Eventually, we output data in integer format at DIO.
|
||||
|
||||
Global Sync
|
||||
-----------
|
||||
|
||||
Many DCN registers are double buffered, most importantly the surface address.
|
||||
This allows us to update DCN hardware atomically for page flips, as well as
|
||||
for most other updates that don't require enabling or disabling of new pipes.
|
||||
|
||||
(Note: There are many scenarios when DC will decide to reserve extra pipes
|
||||
in order to support outputs that need a very high pixel clock, or for
|
||||
power saving purposes.)
|
||||
|
||||
These atomic register updates are driven by global sync signals in DCN. In
|
||||
order to understand how atomic updates interact with DCN hardware, and how DCN
|
||||
signals page flip and vblank events it is helpful to understand how global sync
|
||||
is programmed.
|
||||
|
||||
Global sync consists of three signals, VSTARTUP, VUPDATE, and VREADY. These are
|
||||
calculated by the Display Mode Library - DML (drivers/gpu/drm/amd/display/dc/dml)
|
||||
based on a large number of parameters and ensure our hardware is able to feed
|
||||
the DCN pipeline without underflows or hangs in any given system configuration.
|
||||
The global sync signals always happen during VBlank, are independent from the
|
||||
VSync signal, and do not overlap each other.
|
||||
|
||||
VUPDATE is the only signal that is of interest to the rest of the driver stack
|
||||
or userspace clients as it signals the point at which hardware latches to
|
||||
atomically programmed (i.e. double buffered) registers. Even though it is
|
||||
independent of the VSync signal we use VUPDATE to signal the VSync event as it
|
||||
provides the best indication of how atomic commits and hardware interact.
|
||||
|
||||
Since DCN hardware is double-buffered the DC driver is able to program the
|
||||
hardware at any point during the frame.
|
||||
|
||||
The below picture illustrates the global sync signals:
|
||||
|
||||
.. kernel-figure:: global_sync_vblank.svg
|
||||
|
||||
These signals affect core DCN behavior. Programming them incorrectly will lead
|
||||
to a number of negative consequences, most of them quite catastrophic.
|
||||
|
||||
The following picture shows how global sync allows for a mailbox style of
|
||||
updates, i.e. it allows for multiple re-configurations between VUpdate
|
||||
events where only the last configuration programmed before the VUpdate signal
|
||||
becomes effective.

===================================
|
||||
drm/amd/display - Display Core (DC)
|
||||
===================================
|
||||
|
||||
AMD display engine is partially shared with other operating systems; for this
|
||||
reason, our Display Core Driver is divided into two pieces:
|
||||
|
||||
1. **Display Core (DC)** contains the OS-agnostic components. Things like
|
||||
hardware programming and resource management are handled here.
|
||||
2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
|
||||
amdgpu base driver and DRM are implemented here.
|
||||
|
||||
The display pipe is responsible for "scanning out" a rendered frame from the
|
||||
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.
|
||||
|
||||

||||

Core Driver Infrastructure
|
||||
============================
|
||||
|
||||
GPU Hardware Structure
|
||||
======================
|
||||
|
||||
Each ASIC is a collection of hardware blocks. We refer to them as
|
||||
"IPs" (Intellectual Property blocks). Each IP encapsulates certain
|
||||
functionality. IPs are versioned and can also be mixed and matched.
|
||||
E.g., you might have two different ASICs that both have System DMA (SDMA) 5.x IPs.
|
||||
The driver is arranged by IPs. There are driver components to handle
|
||||
the initialization and operation of each IP. There are also a bunch
|
||||
of smaller IPs that don't really need much if any driver interaction.
|
||||
Those end up getting lumped into the common stuff in the soc files.
|
||||
The soc files (e.g., vi.c, soc15.c nv.c) contain code for aspects of
|
||||
the SoC itself rather than specific IPs. E.g., things like GPU resets
|
||||
and register access functions are SoC dependent.
|
||||
|
||||
An APU contains more than just CPU and GPU, it also contains all of
|
||||
the platform stuff (audio, usb, gpio, etc.). Also, a lot of
|
||||
components are shared between the CPU, platform, and the GPU (e.g.,
|
||||
SMU, PSP, etc.). Specific components (CPU, GPU, etc.) usually have
|
||||
their interface to interact with those common components. For things
|
||||
like S0i3 there is a ton of coordination required across all the
|
||||
components, but that is probably a bit beyond the scope of this
|
||||
section.
|
||||
|
||||
With respect to the GPU, we have the following major IPs:
|
||||
|
||||
GMC (Graphics Memory Controller)
|
||||
This was a dedicated IP on older pre-vega chips, but has since
|
||||
become somewhat decentralized on vega and newer chips. They now
|
||||
have dedicated memory hubs for specific IPs or groups of IPs. We
|
||||
still treat it as a single component in the driver however since
|
||||
the programming model is still pretty similar. This is how the
|
||||
different IPs on the GPU get the memory (VRAM or system memory).
|
||||
It also provides the support for per process GPU virtual address
|
||||
spaces.
|
||||
|
||||
IH (Interrupt Handler)
|
||||
This is the interrupt controller on the GPU. All of the IPs feed
|
||||
their interrupts into this IP and it aggregates them into a set of
|
||||
ring buffers that the driver can parse to handle interrupts from
|
||||
different IPs.
|
||||
|
||||
PSP (Platform Security Processor)
|
||||
This handles security policy for the SoC and executes trusted
|
||||
applications, and validates and loads firmwares for other blocks.
|
||||
|
||||
SMU (System Management Unit)
|
||||
This is the power management microcontroller. It manages the entire
|
||||
SoC. The driver interacts with it to control power management
|
||||
features like clocks, voltages, power rails, etc.
|
||||
|
||||
DCN (Display Controller Next)
|
||||
This is the display controller. It handles the display hardware.
|
||||
It is described in more details in :ref:`Display Core <amdgpu-display-core>`.
|
||||
|
||||
SDMA (System DMA)
|
||||
This is a multi-purpose DMA engine. The kernel driver uses it for
|
||||
various things including paging and GPU page table updates. It's also
|
||||
exposed to userspace for use by user mode drivers (OpenGL, Vulkan,
|
||||
etc.)
|
||||
|
||||
GC (Graphics and Compute)
|
||||
This is the graphics and compute engine, i.e., the block that
|
||||
encompasses the 3D pipeline and and shader blocks. This is by far the
|
||||
largest block on the GPU. The 3D pipeline has tons of sub-blocks. In
|
||||
addition to that, it also contains the CP microcontrollers (ME, PFP,
|
||||
CE, MEC) and the RLC microcontroller. It's exposed to userspace for
|
||||
user mode drivers (OpenGL, Vulkan, OpenCL, etc.)
|
||||
|
||||
VCN (Video Core Next)
|
||||
This is the multi-media engine. It handles video and image encode and
|
||||
decode. It's exposed to userspace for user mode drivers (VA-API,
|
||||
OpenMAX, etc.)
|
||||
|
||||
Graphics and Compute Microcontrollers
|
||||
-------------------------------------
|
||||
|
||||
CP (Command Processor)
|
||||
The name for the hardware block that encompasses the front end of the
|
||||
GFX/Compute pipeline. Consists mainly of a bunch of microcontrollers
|
||||
(PFP, ME, CE, MEC). The firmware that runs on these microcontrollers
|
||||
provides the driver interface to interact with the GFX/Compute engine.
|
||||
|
||||
MEC (MicroEngine Compute)
|
||||
This is the microcontroller that controls the compute queues on the
|
||||
GFX/compute engine.
|
||||
|
||||
MES (MicroEngine Scheduler)
|
||||
This is a new engine for managing queues. This is currently unused.
|
||||
|
||||
RLC (RunList Controller)
|
||||
This is another microcontroller in the GFX/Compute engine. It handles
|
||||
power management related functionality within the GFX/Compute engine.
|
||||
The name is a vestige of old hardware where it was originally added
|
||||
and doesn't really have much relation to what the engine does now.
|
||||
|
||||
Driver Structure
|
||||
================
|
||||
|
||||
In general, the driver has a list of all of the IPs on a particular
|
||||
SoC and for things like init/fini/suspend/resume, more or less just
|
||||
walks the list and handles each IP.
|
||||
|
||||
Some useful constructs:
|
||||
|
||||
KIQ (Kernel Interface Queue)
|
||||
This is a control queue used by the kernel driver to manage other gfx
|
||||
and compute queues on the GFX/compute engine. You can use it to
|
||||
map/unmap additional queues, etc.
|
||||
|
||||
IB (Indirect Buffer)
|
||||
A command buffer for a particular engine. Rather than writing
|
||||
commands directly to the queue, you can write the commands into a
|
||||
piece of memory and then put a pointer to the memory into the queue.
|
||||
The hardware will then follow the pointer and execute the commands in
|
||||
the memory, then returning to the rest of the commands in the ring.

===========
|

Sample code for testing error injection can be found here:
|
||||
https://cgit.freedesktop.org/mesa/drm/tree/tests/amdgpu/ras_tests.c
|
||||
|
||||
This is part of the libdrm amdgpu unit tests which cover several areas of the GPU.
|
||||
There are four sets of tests:
|
||||
|
||||
RAS Basic Test
|
||||
|
||||
The test verifies the RAS feature enabled status and makes sure the necessary sysfs and debugfs files
|
||||
are present.
|
||||
|
||||
RAS Query Test
|
||||
|
||||
This test checks the RAS availability and enablement status for each supported IP block as well as
|
||||
the error counts.
|
||||
|
||||
RAS Inject Test
|
||||
|
||||
This test injects errors for each IP.
|
||||
|
||||
RAS Disable Test
|
||||
|
||||
This test tests disabling of RAS features for each IP block.
