663d2daeae drm/amd/display: Add odm seamless boot support
[WHY]
Implement changes to transition from Pre-OS odm to
Post-OS odm support. Seamless boot case is also
considered.

[HOW]
Revised validation logic when marking for seamless
boot. Init resources accordingly when Pre-OS has
odm enabled. Reset odm and det size when transitioning
Pre-OS odm to Post-OS non-odm to avoid corruption.
Apply logic to set odm accordingly upon commit.

593692d2de drm/amd/display: Power down hardware if timer not trigger
[WHY]
In headless systems, if SetMode/Power down timer
is not called, hardware will not be powered down
causing HW/SW discrepancies. Powering down hardware
on SetPowerState to D3 will ensure SW/HW state is accurate.

[WHY]
Screen was seen corrupted for a few ms
when switching both ways. There was also
not enough bandwidth for HDR to be
enabled in HG disabled mode.
This was due to FEC being

or disabled for the EDP.

[HOW]

or if DSC should be disabled for EDP
before enabling FEC for EDP.

2513ed4f93 drm/amd/display: do not wait for mpc idle if tg is disabled
[Why]
When booting, the driver waits for the MPC idle bit to be set as part of
pipe initialization. However, on some systems this occurs before OTG is
enabled, and since the MPC idle bit won't be set until the vupdate
signal occurs (which requires OTG to be enabled), this never happens and
the wait times out. This can add hundreds of milliseconds to the boot
time.

Do not wait for mpc idle if tg is disabled

6f90a49bc0 drm/amdgpu: Fix incorrect enum type
Instead of the 'amdgpu_ring_priority_level' type,
the 'amdgpu_gfx_pipe_priority' type was used,
which is an error when setting ring priority.
This is a minor error, but may cause problems in the future.

Instead of AMDGPU_RING_PRIO_2 = 2, we can use AMDGPU_RING_PRIO_MAX = 3,
but AMDGPU_RING_PRIO_2 = 2 is used for compatibility with
AMDGPU_GFX_PIPE_PRIO_HIGH = 2, and not change the behavior of the

moving amdgpu_asic_reset() to noirq callback, so it's called after HDA

67229b27ed drm/amd/display: don't ignore alpha property on pre-multiplied mode
"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c

In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:

out.rgb = plane_alpha * fg.rgb +
          (1 - (plane_alpha * fg.alpha)) * bg.rgb

Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).

With this change, alpha property stops to be ignored. It also addresses
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734

v2:
 * keep the 8-bit value for global_alpha_value (Nicholas)
 * correct the logical ordering for combined global gain (Nicholas)
 * apply to dcn10 too (Nicholas)

5273e82c5f drm/amdkfd: Improve concurrency of event handling
Use rcu_read_lock to read p->event_idr concurrently with other readers
and writers. Use p->event_mutex only for creating and destroying events
and in kfd_wait_on_events.

Protect the contents of the kfd_event structure with a per-event
spinlock that can be taken inside the rcu_read_lock critical section.

This eliminates contention of p->event_mutex in set_event, which tends
to be on the critical path for dispatch latency even when busy waiting
is used. It also eliminates lock contention in event interrupt handlers.
Since the p->event_mutex is now used much less, the impact of requiring
it in kfd_wait_on_events should also be much smaller.

This should improve event handling latency for processes using multiple

46b35b33cc dma-buf: wait for map to complete for static attachments

7bc80a5462 dma-buf: add enum dma_resv_usage v4
This change adds the dma_resv_usage enum and allows us to specify why a
dma_resv object is queried for its containing fences.

Additional to that a dma_resv_usage_rw() helper function is added to aid
retrieving the fences for a read or write userspace submission.

This is then deployed to the different query functions of the dma_resv
object and all of their users. When the write paratermer was previously
true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise.

v2: add KERNEL/OTHER in separate patch
v3: some kerneldoc suggestions by Daniel
v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in

It calles populate_dml_pipes which uses doubles to initialize.
Adding FPU protection avoids context switch and probable loss of vba context
as there is potential contention while drm debug logs are enabled.
