fac53471d0 drm/amdgpu: TA unload messages are not actually sent to psp when amdgpu is uninstalled
V1:
  The psp_cmd_submit_buf function is called by psp_hw_fini to send
TA unload messages to psp to terminate ras, asd and tmr. But when
amdgpu is uninstalled, drm_dev_unplug is called earlier than
psp_hw_fini in amdgpu_pci_remove, the calling order as follows:
static void amdgpu_pci_remove(struct pci_dev *pdev) {
	drm_dev_unplug
	......
	amdgpu_driver_unload_kms->amdgpu_device_fini_hw->...
		->.hw_fini->psp_hw_fini->...
		->psp_ta_unload->psp_cmd_submit_buf
	......
}
The program will return when calling drm_dev_enter in psp_cmd_submit_buf.

So the call to drm_dev_enter in psp_cmd_submit_buf should be
removed, so that the TA unload messages can be sent to the psp
when amdgpu is uninstalled.

V2:
1. Restore psp_cmd_submit_buf to its original code.
2. Move drm_dev_unplug call after amdgpu_driver_unload_kms in
   amdgpu_pci_remove.
3. Since amdgpu_device_fini_hw is called by amdgpu_driver_unload_kms,
   remove the unplug check to release device mmio resource in
   amdgpu_device_fini_hw before calling drm_dev_unplug.

8284182592 drm/admgpu: Skip CG/PG on SOC21 under SRIOV VF
[Why]
There is no CG(Clock Gating)/PG(Power Gating) requirement on SRIOV VF.
For multi VF, VF should not enable any CG/PG features.
For one VF, PF will program CG/PG related registers.

[How]
Do not set any cg/pg flag bit at early init under sriov.

bbb860d46f drm/amdgpu: Use RLCG to program GRBM_GFX_CNTL during full access time
[Why]
KIQ register init requires GRBM_GFX_CNTL to select KIQ.

[How]
As RLCG accessing registers will save the data of GRBM_GFX_CNTL and restore it.
Use RLCG indirect accessing register method to select grbm instead of mmio directly access.

2581c5d85e drm/amdgpu: Fix use-after-free in amdgpu_cs_ioctl
[Why]
In amdgpu_cs_ioctl, amdgpu_job_free could be performed ealier if there
is -ERESTARTSYS error. In this case, job->hw_fence could be not
initialized yet. Putting hw_fence during amdgpu_job_free could lead to a
use-after-free warning.

[How]
Check if drm_sched_job_init is performed before job_free by checking
s_fence.

v2: Check hw_fence.ops instead since it could be NULL if fence is not
initialized. Reverse the condition since !=NULL check is discouraged in
kernel.
