Pull drm updates from Dave Airlie: "New xilinx displayport driver, AMD support for two new GPUs (more header files), i915 initial support for RocketLake and some work on their DG1 (discrete chip). The core also grew some lockdep annotations to try and constrain what drivers do with dma-fences, and added some documentation on why the idea of indefinite fences doesn't work. The long list is below. I do have some fixes trees outstanding, but I'll follow up with those later. core: - add user def flag to cmd line modes - dma_fence_wait added might_sleep - dma-fence lockdep annotations - indefinite fences are bad documentation - gem CMA functions used in more drivers - struct mutex removal - more drm_ debug macro usage - set/drop master api fixes - fix for drm/mm hole size comparison - drm/mm remove invalid entry optimization - optimise drm/mm hole handling - VRR debugfs added - uncompressed AFBC modifier support - multiple display id blocks in EDID - multiple driver sg handling fixes - __drm_atomic_helper_crtc_reset in all drivers - managed vram helpers ttm: - ttm_mem_reg handling cleanup - remove bo offset field - drop CMA memtype flag - drop mappable flag xilinx: - New Xilinx ZynqMP DisplayPort Subsystem driver nouveau: - add CRC support - start using NVIDIA published class header files - convert all push buffer emission to new macros - Proper push buffer space management for EVO/NVD channels. - firmware loading fixes - 2MiB system memory pages support on Pascal and newer vkms: - larger cursor support i915: - Rocketlake platform enablement - Early DG1 enablement - Numerous GEM refactorings - DP MST fixes - FBC, PSR, Cursor, Color, Gamma fixes - TGL, RKL, EHL workaround updates - TGL 8K display support fixes - SDVO/HDMI/DVI fixes amdgpu: - Initial support for Sienna Cichlid GPU - Initial support for Navy Flounder GPU - SI UVD/VCE support - expose rotation property - Add support for unique id on Arcturus - Enable runtime PM on vega10 boards that support BACO - Skip BAR resizing if the bios already did id - Major swSMU code cleanup - Fixes for DCN bandwidth calculations amdkfd: - Track SDMA usage per process - SMI events interface radeon: - Default to on chip GART for AGP boards on all arches - Runtime PM reference count fixes msm: - headers regenerated causing churn - a650/a640 display and GPU enablement - dpu dither support for 6bpc panels - dpu cursor fix - dsi/mdp5 enablement for sdm630/sdm636/sdm66 tegra: - video capture prep support - reflection support mediatek: - convert mtk_dsi to bridge API meson: - FBC support sun4i: - iommu support rockchip: - register locking fix - per-pixel alpha support PX30 VOP mgag200: - ported to simple and shmem helpers - device init cleanups - use managed pci functions - dropped hw cursor support ast: - use managed pci functions - use managed VRAM helpers - rework cursor support malidp: - dev_groups support hibmc: - refactor hibmc_drv_vdac: vc4: - create TXP CRTC imx: - error path fixes and cleanups etnaviv: - clock handling and error handling cleanups - use pin_user_pages" * tag 'drm-next-2020-08-06' of git://anongit.freedesktop.org/drm/drm: (1747 commits) drm/msm: use kthread_create_worker instead of kthread_run drm/msm/mdp5: Add MDP5 configuration for SDM636/660 drm/msm/dsi: Add DSI configuration for SDM660 drm/msm/mdp5: Add MDP5 configuration for SDM630 drm/msm/dsi: Add phy configuration for SDM630/636/660 drm/msm/a6xx: add A640/A650 hwcg drm/msm/a6xx: hwcg tables in gpulist drm/msm/dpu: add SM8250 to hw catalog drm/msm/dpu: add SM8150 to hw catalog drm/msm/dpu: intf timing path for displayport drm/msm/dpu: set missing flush bits for INTF_2 and INTF_3 drm/msm/dpu: don't use INTF_INPUT_CTRL feature on sdm845 drm/msm/dpu: move some sspp caps to dpu_caps drm/msm/dpu: update UBWC config for sm8150 and sm8250 drm/msm/dpu: use right setup_blend_config for sm8150 and sm8250 drm/msm/a6xx: set ubwc config for A640 and A650 drm/msm/adreno: un-open-code some packets drm/msm: sync generated headers drm/msm/a6xx: add build_bw_table for A640/A650 drm/msm/a6xx: fix crashstate capture for A650 ...

Renesas R-Car LVDS Encoder
|
||||
==========================
|
||||
|
||||
These DT bindings describe the LVDS encoder embedded in the Renesas R-Car
|
||||
Gen2, R-Car Gen3 and RZ/G SoCs.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : Shall contain one of
|
||||
- "renesas,r8a7743-lvds" for R8A7743 (RZ/G1M) compatible LVDS encoders
|
||||
- "renesas,r8a7744-lvds" for R8A7744 (RZ/G1N) compatible LVDS encoders
|
||||
- "renesas,r8a774a1-lvds" for R8A774A1 (RZ/G2M) compatible LVDS encoders
|
||||
- "renesas,r8a774b1-lvds" for R8A774B1 (RZ/G2N) compatible LVDS encoders
|
||||
- "renesas,r8a774c0-lvds" for R8A774C0 (RZ/G2E) compatible LVDS encoders
|
||||
- "renesas,r8a7790-lvds" for R8A7790 (R-Car H2) compatible LVDS encoders
|
||||
- "renesas,r8a7791-lvds" for R8A7791 (R-Car M2-W) compatible LVDS encoders
|
||||
- "renesas,r8a7793-lvds" for R8A7793 (R-Car M2-N) compatible LVDS encoders
|
||||
- "renesas,r8a7795-lvds" for R8A7795 (R-Car H3) compatible LVDS encoders
|
||||
- "renesas,r8a7796-lvds" for R8A7796 (R-Car M3-W) compatible LVDS encoders
|
||||
- "renesas,r8a77965-lvds" for R8A77965 (R-Car M3-N) compatible LVDS encoders
|
||||
- "renesas,r8a77970-lvds" for R8A77970 (R-Car V3M) compatible LVDS encoders
|
||||
- "renesas,r8a77980-lvds" for R8A77980 (R-Car V3H) compatible LVDS encoders
|
||||
- "renesas,r8a77990-lvds" for R8A77990 (R-Car E3) compatible LVDS encoders
|
||||
- "renesas,r8a77995-lvds" for R8A77995 (R-Car D3) compatible LVDS encoders
|
||||
|
||||
- reg: Base address and length for the memory-mapped registers
|
||||
- clocks: A list of phandles + clock-specifier pairs, one for each entry in
|
||||
the clock-names property.
|
||||
- clock-names: Name of the clocks. This property is model-dependent.
|
||||
- The functional clock, which mandatory for all models, shall be listed
|
||||
first, and shall be named "fck".
|
||||
- On R8A77990, R8A77995 and R8A774C0, the LVDS encoder can use the EXTAL or
|
||||
DU_DOTCLKINx clocks. Those clocks are optional. When supplied they must be
|
||||
named "extal" and "dclkin.x" respectively, with "x" being the DU_DOTCLKIN
|
||||
numerical index.
|
||||
- When the clocks property only contains the functional clock, the
|
||||
clock-names property may be omitted.
|
||||
- resets: A phandle + reset specifier for the module reset
|
||||
|
||||
Required nodes:
|
||||
|
||||
The LVDS encoder has two video ports. Their connections are modelled using the
|
||||
OF graph bindings specified in Documentation/devicetree/bindings/graph.txt.
|
||||
|
||||
- Video port 0 corresponds to the parallel RGB input
|
||||
- Video port 1 corresponds to the LVDS output
|
||||
|
||||
Each port shall have a single endpoint.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- renesas,companion : phandle to the companion LVDS encoder. This property is
|
||||
mandatory for the first LVDS encoder on D3 and E3 SoCs, and shall point to
|
||||
the second encoder to be used as a companion in dual-link mode. It shall not
|
||||
be set for any other LVDS encoder.

more than one power supply with panel-specific constraints governing the

supply is sufficient, either because the panel has a single power rail, or

because all its power rails can be driven by the same supply. In that case

Sharp Microelectronics 10.1" WQXGA TFT LCD panel
|
||||
|
||||
This panel requires a dual-channel DSI host to operate. It supports two modes:
|
||||
- left-right: each channel drives the left or right half of the screen
|
||||
- even-odd: each channel drives the even or odd lines of the screen
|
||||
|
||||
Each of the DSI channels controls a separate DSI peripheral. The peripheral
|
||||
driven by the first link (DSI-LINK1), left or even, is considered the primary
|
||||
peripheral and controls the device. The 'link2' property contains a phandle
|
||||
to the peripheral driven by the second link (DSI-LINK2, right or odd).
|
||||
|
||||
Note that in video mode the DSI-LINK1 interface always provides the left/even
|
||||
pixels and DSI-LINK2 always provides the right/odd pixels. In command mode it
|
||||
is possible to program either link to drive the left/even or right/odd pixels
|
||||
but for the sake of consistency this binding assumes that the same assignment
|
||||
is chosen as for video mode.
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "sharp,lq101r1sx01"
|
||||
- reg: DSI virtual channel of the peripheral
|
||||
|
||||
Required properties (for DSI-LINK1 only):
|
||||
- link2: phandle to the DSI peripheral on the secondary link. Note that the
|
||||
presence of this property marks the containing node as DSI-LINK1.
|
||||
- power-supply: phandle of the regulator that provides the supply voltage
|
||||
|
||||
Optional properties (for DSI-LINK1 only):
|
||||
- backlight: phandle of the backlight device attached to the panel
|
||||
|
||||

description: |
|

The DisplayPort subsystem of Xilinx ZynqMP (Zynq UltraScale+ MPSoC)
|

implements the display and audio pipelines based on the DisplayPort v1.2
|

standard. The subsystem includes multiple functional blocks as below:

Blended Video and
|
||||
Mixed Audio to PL
|
||||
|
||||
The Buffer Manager interacts with external interface such as DMA engines or
|
||||
live audio/video streams from the programmable logic. The Video Rendering
|
||||
Pipeline blends the video and graphics layers and performs colorspace
|
||||
conversion. The Audio Mixer mixes the incoming audio streams. The DisplayPort
|
||||
Source Controller handles the DisplayPort protocol and connects to external
|
||||
PHYs.
|
||||
|
||||
The subsystem supports 2 video and 2 audio streams, and various pixel formats
|
||||
and depths up to 4K@30 resolution.

Indefinite DMA Fences
|

~~~~~~~~~~~~~~~~~~~~
|

|
||||
At various times &dma_fence with an indefinite time until dma_fence_wait()
|
||||
finishes have been proposed. Examples include:
|
||||
|
||||
* Future fences, used in HWC1 to signal when a buffer isn't used by the display
|
||||
any longer, and created with the screen update that makes the buffer visible.
|
||||
The time this fence completes is entirely under userspace's control.
|
||||
|
||||
* Proxy fences, proposed to handle &drm_syncobj for which the fence has not yet
|
||||
been set. Used to asynchronously delay command submission.
|
||||
|
||||
* Userspace fences or gpu futexes, fine-grained locking within a command buffer
|
||||
that userspace uses for synchronization across engines or with the CPU, which
|
||||
are then imported as a DMA fence for integration into existing winsys
|
||||
protocols.
|
||||
|
||||
* Long-running compute command buffers, while still using traditional end of
|
||||
batch DMA fences for memory management instead of context preemption DMA
|
||||
fences which get reattached when the compute job is rescheduled.
|
||||
|
||||
Common to all these schemes is that userspace controls the dependencies of these
|
||||
fences and controls when they fire. Mixing indefinite fences with normal
|
||||
in-kernel DMA fences does not work, even when a fallback timeout is included to
|
||||
protect against malicious userspace:
|
||||
|
||||
* Only the kernel knows about all DMA fence dependencies, userspace is not aware
|
||||
of dependencies injected due to memory management or scheduler decisions.
|
||||
|
||||
* Only userspace knows about all dependencies in indefinite fences and when
|
||||
exactly they will complete, the kernel has no visibility.
|
||||
|
||||
Furthermore the kernel has to be able to hold up userspace command submission
|
||||
for memory management needs, which means we must support indefinite fences being
|
||||
dependent upon DMA fences. If the kernel also support indefinite fences in the
|
||||
kernel like a DMA fence, like any of the above proposal would, there is the
|
||||
potential for deadlocks.

This means that the kernel might accidentally create deadlocks
|
||||
through memory management dependencies which userspace is unaware of, which
|
||||
randomly hangs workloads until the timeout kicks in. Workloads, which from
|
||||
userspace's perspective, do not contain a deadlock. In such a mixed fencing
|
||||
architecture there is no single entity with knowledge of all dependencies.
|
||||
Thefore preventing such deadlocks from within the kernel is not possible.
|
||||
|
||||
The only solution to avoid dependencies loops is by not allowing indefinite
|
||||
fences in the kernel. This means:
|
||||
|
||||
* No future fences, proxy fences or userspace fences imported as DMA fences,
|
||||
with or without a timeout.
|
||||
|
||||
* No DMA fences that signal end of batchbuffer for command submission where
|
||||
userspace is allowed to use userspace fencing or long running compute
|
||||
workloads. This also means no implicit fencing for shared buffers in these
|
||||
cases.
