aec3bb3a01 drm/amdgpu: make psp_ring_init common
All of the IP specific versions are the same now, so
we can just use a common function.

3e93136809 drm/amdgpu: remove the check of init status in psp_ras_initialize
The initialized status indicates RAS TA is loaded, but in some cases
(such as RAS fatal error) RAS TA could be destroyed although it's not
unloaded. Hence we load RAS TA unconditionally here.

7117007eda drm/amdgpu: Move the mutex_lock to protect the return status of securedisplay command buffer
[Why]
Before we call psp_securedisplay_invoke(), we call
psp_prep_securedisplay_cmd_buf() to prepare and initialize the command
buffer.

However, we didn't use the mutex_lock to protect the status of command
buffer. So when multiple threads are using the command buffer, after
thread A return from psp_securedisplay_invoke() and the command buffer
status is set to SUCCESS, another thread B may call
psp_prep_securedisplay_cmd_buf() and initialize the status to FAILURE
again, and cause Thread A to get a failure return status.

[How]
Move the mutex_lock out of psp_securedisplay_invoke() to its caller to
cover psp_prep_securedisplay_cmd_buf() and the code checking the return
status of command buffer.

83d29a5f8a drm/amdgpu: Fixed psp fence and memory issues when removing amdgpu device
V3:
Fixed psp fence and memory issues for the asic
using smu v13_0_2 when removing amdgpu device.

[Why]:
1. psp_suspend->psp_free_shared_bufs->
       psp_ta_free_shared_buf->
           amdgpu_bo_free_kernel->
             ...->amdgpu_bo_release_notify->
                    amdgpu_fill_buffer
   psp will free vram memory used by psp when psp_suspend
   is called. But for the asic using smu v13_0_2, because
   psp_suspend is called before adev->shutdown is set to
   true when removing the first hive device, amdgpu fill_buffer
   will be called, which will cause fence issues when evicting
   all vram resources in amdgpu vram mgr_fini.
2. Since psp_hw_fini is not called after calling psp_suspend
   and psp_suspend only calls psp_ring_stop, the psp ring memory
   will not be released when amdgpu device is removed.

[How]:
1. Set shutdown to true before calling amdgpu_device_gpu_recover,
   then amdgpu_fill_buffer will not be called when psp_suspend is
   called.
2. Free psp ring memory in psp_sw_fini.

c4381d0ee8 drm/amdgpu: Add interface to load SRIOV cap FW
- Add interface to load SRIOV cap FW. If the FW does not
  exist, simply skip this FW loading routine.
  This FW will only be loaded under SRIOV. Other driver
  configuration will not be affected.
  By adding this interface, it will make us easier to
  prepare SRIOV Linux guest driver for different users.

- Update sysfs interface to read cap FW version.

- Refactor PSP FW loading routine under SRIOV to use a
  unified SWITCH statement instead of using IF statement

- Remove redundant amdgpu_sriov_vf() check in FW loading
  routine
