Merge tag 'drm-next-2020-08-06' of git://anongit.freedesktop.org/drm/drm

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

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,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.
Example:
lvds0: lvds@feb90000 {
compatible = "renesas,r8a77990-lvds";
reg = <0 0xfeb90000 0 0x20>;
clocks = <&cpg CPG_MOD 727>;
power-domains = <&sysc R8A77990_PD_ALWAYS_ON>;
resets = <&cpg 727>;
renesas,companion = <&lvds1>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
lvds0_in: endpoint {
remote-endpoint = <&du_out_lvds0>;
};
};
port@1 {
reg = <1>;
lvds0_out: endpoint {
};

Required nodes:
This device has two video ports. Their connections are modeled using the OF
graph bindings specified in [1]. Each port node shall have a single endpoint.
- Port 0 is the DPI input port. Its endpoint subnode shall contain a
pclk-sample and bus-width property and a remote-endpoint property as specified
in [1].
- If pclk-sample is not defined, pclk-sample = 0 should be assumed for
backward compatibility.
- If bus-width is not defined then bus-width = 24 should be assumed for
backward compatibility.
bus-width = 24: 24 data lines are connected and single-edge mode
bus-width = 12: 12 data lines are connected and dual-edge mode
- Port 1 is the DVI output port. Its endpoint subnode shall contain a
remote-endpoint property is specified in [1].

Display panels require power to be supplied. While several panels need
more than one power supply with panel-specific constraints governing the
order and timings of the power supplies, in many cases a single power
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
the vddi-supply property specifies the supply powering the panel as a
phandle to a regulator.

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
Example:
dsi@54300000 {
panel: panel@0 {
compatible = "sharp,lq101r1sx01";
reg = <0>;
link2 = <&secondary>;
power-supply = <...>;

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.

:internal:
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.
.. kernel-render:: DOT
:alt: Indefinite Fencing Dependency Cycle
:caption: Indefinite Fencing Dependency Cycle
digraph "Fencing Cycle" {
node [shape=box bgcolor=grey style=filled]
kernel [label="Kernel DMA Fences"]
userspace [label="userspace controlled fences"]
kernel -> userspace [label="memory management"]
userspace -> kernel [label="Future fence, fence proxy, ..."]
{ rank=same; kernel userspace }
}
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,

- DMA_REPEAT
- The device supports repeated transfers. A repeated transfer, indicated by
the DMA_PREP_REPEAT transfer flag, is similar to a cyclic transfer in that
it gets automatically repeated when it ends, but can additionally be
replaced by the client.
- This feature is limited to interleaved transfers, this flag should thus not
be set if the DMA_INTERLEAVE flag isn't set. This limitation is based on
the current needs of DMA clients, support for additional transfer types
should be added in the future if and when the need arises.
- DMA_LOAD_EOT
- The device supports replacing repeated transfers at end of transfer (EOT)
by queuing a new transfer with the DMA_PREP_LOAD_EOT flag set.
- Support for replacing a currently running transfer at another point (such
as end of burst instead of end of transfer) will be added in the future
based on DMA clients needs, if and when the need arises.
These various types will also affect how the source and destination

- DMA_PREP_REPEAT
- If set, the transfer will be automatically repeated when it ends until a
new transfer is queued on the same channel with the DMA_PREP_LOAD_EOT flag.
If the next transfer to be queued on the channel does not have the
DMA_PREP_LOAD_EOT flag set, the current transfer will be repeated until the
client terminates all transfers.
- This flag is only supported if the channel reports the DMA_REPEAT
capability.
- DMA_PREP_LOAD_EOT
- If set, the transfer will replace the transfer currently being executed at
the end of the transfer.
- This is the default behaviour for non-repeated transfers, specifying
DMA_PREP_LOAD_EOT for non-repeated transfers will thus make no difference.
- When using repeated transfers, DMA clients will usually need to set the
DMA_PREP_LOAD_EOT flag on all transfers, otherwise the channel will keep
repeating the last repeated transfer and ignore the new transfers being
queued. Failure to set DMA_PREP_LOAD_EOT will appear as if the channel was
stuck on the previous transfer.
- This flag is only supported if the channel reports the DMA_LOAD_EOT
capability.

* DOC: fence cross-driver contract
*
* Since &dma_fence provide a cross driver contract, all drivers must follow the
* same rules:
*
* * Fences must complete in a reasonable time. Fences which represent kernels
* and shaders submitted by userspace, which could run forever, must be backed
* up by timeout and gpu hang recovery code. Minimally that code must prevent
* further command submission and force complete all in-flight fences, e.g.
* when the driver or hardware do not support gpu reset, or if the gpu reset
* failed for some reason. Ideally the driver supports gpu recovery which only
* affects the offending userspace context, and no other userspace
* submissions.
*
* * Drivers may have different ideas of what completion within a reasonable
* time means. Some hang recovery code uses a fixed timeout, others a mix
* between observing forward progress and increasingly strict timeouts.
* Drivers should not try to second guess timeout handling of fences from
* other drivers.
*
* * To ensure there's no deadlocks of dma_fence_wait() against other locks
* drivers should annotate all code required to reach dma_fence_signal(),
* which completes the fences, with dma_fence_begin_signalling() and
* dma_fence_end_signalling().
*
* * Drivers are allowed to call dma_fence_wait() while holding dma_resv_lock().
* This means any code required for fence completion cannot acquire a
* &dma_resv lock. Note that this also pulls in the entire established
* locking hierarchy around dma_resv_lock() and dma_resv_unlock().
*
* * Drivers are allowed to call dma_fence_wait() from their &shrinker
* callbacks. This means any code required for fence completion cannot
* allocate memory with GFP_KERNEL.
*
* * Drivers are allowed to call dma_fence_wait() from their &mmu_notifier
* respectively &mmu_interval_notifier callbacks. This means any code required
* for fence completeion cannot allocate memory with GFP_NOFS or GFP_NOIO.
* Only GFP_ATOMIC is permissible, which might fail.
*
* Note that only GPU drivers have a reasonable excuse for both requiring
* &mmu_interval_notifier and &shrinker callbacks at the same time as having to
* track asynchronous compute work using &dma_fence. No driver outside of
* drivers/gpu should ever call dma_fence_wait() in such contexts.

/**
* DOC: fence signalling annotation
*
* Proving correctness of all the kernel code around &dma_fence through code
* review and testing is tricky for a few reasons:
*
* * It is a cross-driver contract, and therefore all drivers must follow the
* same rules for lock nesting order, calling contexts for various functions
* and anything else significant for in-kernel interfaces. But it is also
* impossible to test all drivers in a single machine, hence brute-force N vs.
* N testing of all combinations is impossible. Even just limiting to the
* possible combinations is infeasible.
*
* * There is an enormous amount of driver code involved. For render drivers
* there's the tail of command submission, after fences are published,
* scheduler code, interrupt and workers to process job completion,
* and timeout, gpu reset and gpu hang recovery code. Plus for integration
* with core mm with have &mmu_notifier, respectively &mmu_interval_notifier,
* and &shrinker. For modesetting drivers there's the commit tail functions
* between when fences for an atomic modeset are published, and when the
* corresponding vblank completes, including any interrupt processing and
* related workers. Auditing all that code, across all drivers, is not
* feasible.
*
* * Due to how many other subsystems are involved and the locking hierarchies
* this pulls in there is extremely thin wiggle-room for driver-specific
* differences. &dma_fence interacts with almost all of the core memory
* handling through page fault handlers via &dma_resv, dma_resv_lock() and
* dma_resv_unlock(). On the other side it also interacts through all
* allocation sites through &mmu_notifier and &shrinker.
*
* Furthermore lockdep does not handle cross-release dependencies, which means
* any deadlocks between dma_fence_wait() and dma_fence_signal() can't be caught
* at runtime with some quick testing. The simplest example is one thread
* waiting on a &dma_fence while holding a lock::
*
* lock(A);
* dma_fence_wait(B);
* unlock(A);
*
* while the other thread is stuck trying to acquire the same lock, which
* prevents it from signalling the fence the previous thread is stuck waiting
* on::
*
* lock(A);
* unlock(A);
* dma_fence_signal(B);
*
* By manually annotating all code relevant to signalling a &dma_fence we can
* teach lockdep about these dependencies, which also helps with the validation
* headache since now lockdep can check all the rules for us::
*
* cookie = dma_fence_begin_signalling();
* lock(A);
* unlock(A);
* dma_fence_signal(B);
* dma_fence_end_signalling(cookie);
*
* For using dma_fence_begin_signalling() and dma_fence_end_signalling() to
* annotate critical sections the following rules need to be observed:
*
* * All code necessary to complete a &dma_fence must be annotated, from the
* point where a fence is accessible to other threads, to the point where
* dma_fence_signal() is called. Un-annotated code can contain deadlock issues,
* and due to the very strict rules and many corner cases it is infeasible to
* catch these just with review or normal stress testing.
*
* * &struct dma_resv deserves a special note, since the readers are only
* protected by rcu. This means the signalling critical section starts as soon
* as the new fences are installed, even before dma_resv_unlock() is called.
*
* * The only exception are fast paths and opportunistic signalling code, which
* calls dma_fence_signal() purely as an optimization, but is not required to
* guarantee completion of a &dma_fence. The usual example is a wait IOCTL
* which calls dma_fence_signal(), while the mandatory completion path goes
* through a hardware interrupt and possible job completion worker.
*
* * To aid composability of code, the annotations can be freely nested, as long
* as the overall locking hierarchy is consistent. The annotations also work
* both in interrupt and process context. Due to implementation details this
* requires that callers pass an opaque cookie from
* dma_fence_begin_signalling() to dma_fence_end_signalling().
*
* * Validation against the cross driver contract is implemented by priming
* lockdep with the relevant hierarchy at boot-up. This means even just
* testing with a single device is enough to validate a driver, at least as
* far as deadlocks with dma_fence_wait() against dma_fence_signal() are
* concerned.
