15caeabc57 drm/amd/display: wait for set pipe mcp command completion
[Why]
When the driver sends a pipe set command to the DMCU FW, it does not wait
for the command to complete. This can lead to unpredictable behavior if,
for example, the driver were to request a pipe disable to the FW via MCP,
then power down some hardware before the firmware has completed processing
the command.

[How]
Wait for the DMCU FW to finish processing set pipe commands

62f3abd153 drm/amd/display: Restore should_update_pstate_support after bad revert
[Why]
This function was mistakenly reverted as part of a legitimate revert. The
old version that was reverted to has bad logic, and is causing situations
where p-state change support is being toggled when it shouldn't be,

f537d474df drm/amd/display: check phy dpalt lane count config
[Why]
Type-c PHY config is not align with dpcd lane count.
When those values didn't match, it cause driver do
link training with 4 lane but phy only can output 2 lane.
The link trainig always fail.

[How]
1. Modify get_max_link_cap function. According DPALT_DP4
to update max lane count.
2. Add dp_mst_verify_link_cap to handle MST case because
we didn't call dp_mst_verify_link_cap for MST case.

register are not initialized for dcn2. This causes all reads of that register

6b855f7b83 drm/amdkfd: Check against device cgroup
Participate in device cgroup. All kfd devices are exposed via /dev/kfd.
So use /dev/dri/renderN node.

Before exposing the device to a task check if it has permission to
access it. If the task (based on its cgroup) can access /dev/dri/renderN
then expose the device via kfd node.

If the task cannot access /dev/dri/renderN then process device data
(pdd) is not created. This will ensure that task cannot use the device.

In sysfs topology, all device nodes are visible irrespective of the task
cgroup. The sysfs node directories are created at driver load time and
cannot be changed dynamically. However, access to information inside
nodes is controlled based on the task's cgroup permissions.

40a9592a26 drm/amdkfd: Fix MQD size calculation
On device initialization, a chunk of GTT memory is pre-allocated for
HIQ and all SDMA queues mqd. The size of this allocation was wrong.
The correct sdma engine number should be PCIe-optimized SDMA engine
number plus xgmi SDMA engine number.

1995b3a35f drm/amdgpu: Fix error handling in amdgpu_ras_recovery_init
Don't set a struct pointer to NULL before freeing its members. It's
hard to see what's happening due to a local pointer-to-pointer data
aliasing con->eh_data.
