Merge drm/drm-next into drm-intel-gt-next
Maarten needs backmerge to account for header file renames/changes which landed via drm-intel-next and are interfering with his pinning work. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

-===================================
-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>``

-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.
-

+========================
+Display Core Debug tools
+========================
+
+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.
+
+If you want to learn more about our driver details, take a look at the below
+table of content:

+============================
+ 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.
