0ccaa3dde9 drm/ast: Rework I/O register setup
There are three different ways of retrieving the I/O-memory ranges
for AST devices: either from PCI BAR 1, from PCI BAR 2 or from PCI
BAR 1 by 'guessing'.

Make the respective code more readable by making each case self-
contained. Also add error checking against the length of the PCI
BARs.

v2:
	* fix I/O range length to 128 bytes
	* fix length test for PCI BAR 2

c350a08ac7 drm/ast: Turn ioregs_lock to modeset_lock
The lock for the I/O registers is only relevant during mode-setting
operations. It protects the registers from concurrent access from
reading EDID information.

Reduce lock coverage to mode setting, rename the lock and move it
entirely into the mode-setting code. No functional changes, as the
I/O lock was never used for anything else than mode setting.

drm/imagination: vm: fix drm_gpuvm reference count
The driver specific reference count indicates whether the VM should be
teared down, whereas GPUVM's reference count indicates whether the VM
structure can finally be freed.

Hence, free the VM structure in pvr_gpuvm_free() and drop the last
GPUVM reference after tearing down the VM. Generally, this prevents
lifetime issues such as the VM being freed as long as drm_gpuvm_bo
structures still hold references to the VM.

drm/imagination: vm: prevent duplicate drm_gpuvm_bo instances
Use drm_gpuvm_bo_obtain() instead of drm_gpuvm_bo_create(). The latter
should only be used in conjunction with drm_gpuvm_bo_obtain_prealloc().

drm_gpuvm_bo_obtain() re-uses existing instances of a given VM and BO

b0a7ce53d4 drm/ttm: Schedule delayed_delete worker closer
Try to allocate system memory on the NUMA node the device is closest to
and try to run delayed_delete workers on a CPU of this node as well.

To optimize the memory clearing operation when a TTM BO gets freed by
the delayed_delete worker, scheduling it closer to a NUMA node where the
memory was initially allocated helps avoid the cases where the worker
gets randomly scheduled on the CPU cores that are across interconnect
boundaries such as xGMI, PCIe etc.

This change helps USWC GTT allocations on NUMA systems (dGPU) and AMD
APU platforms such as GFXIP9.4.3.

38f922a563 drm/sched: Reverse run-queue priority enumeration
Reverse run-queue priority enumeration such that the higest priority is now 0,
and for each consecutive integer the prioirty diminishes.

Run-queues correspond to priorities. To an external observer a scheduler
created with a single run-queue, and another created with
DRM_SCHED_PRIORITY_COUNT number of run-queues, should always schedule
sched->sched_rq[0] with the same "priority", as that index run-queue exists in
both schedulers, i.e. a scheduler with one run-queue or many. This patch makes
it so.

In other words, the "priority" of sched->sched_rq[n], n >= 0, is the same for
any scheduler created with any allowable number of run-queues (priorities), 0
to DRM_SCHED_PRIORITY_COUNT.

5f03a507b2 drm/nouveau: implement 1:1 scheduler - entity relationship
Recent patches to the DRM scheduler [1][2] allow for a variable number
of run-queues and add support for (shared) workqueues rather than
dedicated kthreads per scheduler. This allows us to create a 1:1
relationship between a GPU scheduler and a scheduler entity, in order to
properly support firmware schedulers being able to handle an arbitrary
amount of dynamically allocated command ring buffers. This perfectly
matches Nouveau's needs, hence make use of it.

Topology wise we create one scheduler instance per client (handling
VM_BIND jobs) and one scheduler instance per channel (handling EXEC
jobs).

All channel scheduler instances share a workqueue, but every client
scheduler instance has a dedicated workqueue. The latter is required to
ensure that for VM_BIND job's free_job() work and run_job() work can
always run concurrently and hence, free_job() work can never stall
run_job() work. For EXEC jobs we don't have this requirement, since EXEC
job's free_job() does not require to take any locks which indirectly or
directly are held for allocations elsewhere.

such as drm_atomic_helper_damage_iter_init() that the damage clips should

To be used by drivers that do per-buffer (e.g: virtio-gpu) uploads (rather
than per-plane uploads), since these type of drivers need to handle buffer
damages instead of frame damages.

That way, these drivers could force a full plane update if the framebuffer
attached to a plane's state has changed since the last update (page-flip).

drm: Introduce DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOT
Virtualized drivers place additional restrictions on the cursor plane
which breaks the contract of universal planes. To allow atomic
modesettings with virtualized drivers the clients need to advertise
that they're capable of dealing with those extra restrictions.

To do that introduce DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOT which
lets DRM know that the client is aware of and capable of dealing with
the extra restrictions on the virtual cursor plane.

Setting this option to true makes DRM expose the cursor plane on
virtualized drivers. The userspace is expected to set the hotspots
and handle mouse events on that plane.

drm/atomic: Add support for mouse hotspots
Atomic modesetting code lacked support for specifying mouse cursor
hotspots. The legacy kms DRM_IOCTL_MODE_CURSOR2 had support for setting
the hotspot but the functionality was not implemented in the new atomic
paths.

Due to the lack of hotspots in the atomic paths userspace compositors
completely disable atomic modesetting for drivers that require it (i.e.
all paravirtualized drivers).

This change adds hotspot properties to the atomic codepaths throughtout
the DRM core and will allow enabling atomic modesetting for virtualized
drivers in the userspace.

drm: Disable the cursor plane on atomic contexts with virtualized drivers
Cursor planes on virtualized drivers have special meaning and require
that the clients handle them in specific ways, e.g. the cursor plane
should react to the mouse movement the way a mouse cursor would be
expected to and the client is required to set hotspot properties on it
in order for the mouse events to be routed correctly.

This breaks the contract as specified by the "universal planes". Fix it
by disabling the cursor planes on virtualized drivers while adding
a foundation on top of which it's possible to special case mouse cursor
planes for clients that want it.

Disabling the cursor planes makes some kms compositors which were broken,
e.g. Weston, fallback to software cursor which works fine or at least
better than currently while having no effect on others, e.g. gnome-shell
or kwin, which put virtualized drivers on a deny-list when running in
atomic context to make them fallback to legacy kms and avoid this issue.

4b4af74ab9 drm: allow DRM_MODE_PAGE_FLIP_ASYNC for atomic commits
If the driver supports it, allow user-space to supply the
DRM_MODE_PAGE_FLIP_ASYNC flag to request an async page-flip.
Set drm_crtc_state.async_flip accordingly.

Document that drivers will reject atomic commits if an async
flip isn't possible. This allows user-space to fall back to
something else. For instance, Xorg falls back to a blit.
Another option is to wait as close to the next vblank as
possible before performing the page-flip to reduce latency.

The current implementation of change_lut_val_precision() is just

by just using drm_color_lut_extract() and intel_color_lut_pack()

And as the uapi can't handle >=1.0 values but the hardware
can we need to clamp the results appropriately in the readout
