[Why & How]
Instead of dropping DRR updates, defer them. This fixes issues where
monitor continues to see incorrect refresh rate after VRR was turned off
by userspace.
Fixes: 32953485c558 ("drm/amd/display: Do not update DRR while BW optimizations pending")

[Why]
Now forcing aux->transfer to return 0 when incomplete AUX write is
inappropriate. It should return bytes have been transferred.
[How]
aux->transfer is asked not to change original msg except reply field of
drm_dp_aux_msg structure. Copy the msg->buffer when it's write request,
and overwrite the first byte when sink reply 1 byte indicating partially
written byte number. Then we can return the correct value without
changing the original msg.

limit on MST
Atm, on an MST link in DSC mode
intel_dp_compute_config_link_bpp_limits() calculates the maximum link
bpp limit using the MST root connector's DSC capabilities. That's not
correct in general: the decompression could be performed by a branch
device downstream of the root branch device or the sink itself.
Fix the above by passing to intel_dp_compute_config_link_bpp_limits()
the actual connector being modeset, containing the correct DSC
capabilities.

This patch enables per-queue and per-pipe reset functionality for
GFX IP v9.5.0 when using MEC firmware version 21 (0x15) or later.
This change:
1. Refactors the pipe reset support check in gfx_v9_4_3_pipe_reset_support()
to use the compute_supported_reset flags instead of hardcoding
version checks.
2. Adds support for GFX9.5.0 (IP 9.5.0) with MEC firmware version >= 21
to enable per-queue and per-pipe reset capabilities.
v2: Replaced mec version check with !!(adev->gfx.compute_supported_reset & AMDGPU_RESET_TYPE_PER_PIPE) (Lijo)

The major of dcn and dce irqs share a copy-pasted collection
of copy-pasted function, which is: hpd_ack.
This patch removes the multiple copy-pasted by moving them to
the irq_service.c and make the irq_service's
calls the functions implemented by the irq_service.c
instead.
The hpd_ack function is replaced by hpd0_ack and hpd1_ack, the
required constants are also added.
The changes were not tested on actual hardware. I am only able
to verify that the changes keep the code compileable and do my
best to look repeatedly if I am not actually changing any code.

Commit ded8b3c36f17 ("drm/amdgpu: properly handle GC vs MM in amdgpu_vmid_mgr_init()")
enables all 16 vmids for MMHUB on GC 10 and newer for KGD since
there are no KFD resources using MMHUB. With this change, KFD
starts seeing MMHUB vmids in it's range with no pasid set. As
such there is no need to warn, we can just ignore those interrupts.

This resolves a deadlock between user queue management and GPU reset
paths by enforcing consistent lock ordering.
The deadlock occurred when:
1. Process exit path (amdgpu_userq_mgr_fini) would:
- Take uqm->userq_mutex
- Then try to take adev->userq_mutex for list operations
2. GPU reset path (amdgpu_userq_pre_reset) would:
- Take adev->userq_mutex first (for list traversal)
- Then take uqm->userq_mutex
The solution establishes a strict top-down locking order:
1. Always take adev->userq_mutex before any uqm->userq_mutex
2. Maintain this order consistently across all code paths
Changes made:
- Reordered locking in amdgpu_userq_mgr_fini() to take device lock first
- Kept existing proper order in amdgpu_userq_pre_reset()
- Simplified the fini flow by removing redundant operations
This prevents circular dependencies while maintaining thread safety
during both normal operation and GPU reset scenarios.

[Why & How]
When MST config is unplugged/replugged too quickly, it can potentially
result in a scenario where previous DC state has not been reset before
the HPD link detection sequence begins. In this case, driver will
disable the streams/link prior to re-enabling the link for link
training.
There is a bug in the current logic that does not account for the fact
that current_state can be released and cleared prior to swapping to a
new state (resulting in the pipe_ctx stream pointers to be cleared) in
between disabling streams.
To resolve this, cache the original streams prior to committing any
stream updates.

[Why]
Now forcing aux->transfer to return 0 when incomplete AUX write is
inappropriate. It should return bytes have been transferred.
[How]
aux->transfer is asked not to change original msg except reply field of
drm_dp_aux_msg structure. Copy the msg->buffer when it's write request,
and overwrite the first byte when sink reply 1 byte indicating partially
written byte number. Then we can return the correct value without
changing the original msg.

Switch cancel_delayed_work() to cancel_delayed_work_sync() to ensure
the delayed work has finished executing before proceeding with
resource cleanup. This prevents a potential use-after-free or
NULL dereference if the resume_work is still running during finalization.

After process exit to unmap csa and free GPU vm, if signal is accepted
and then waiting to take vm lock is interrupted and return, it causes
memory leaking and below warning backtrace.
Change to use uninterruptible wait lock fix the issue.
