Guchun Chen 6952e99cfd drm/amdgpu: refine ras related message print
Prefix ras related kernel message logging with PCI
device info by replacing DRM_INFO/WARN/ERROR with
dev_info/warn/err. This can clearly tell user about
GPU device information where ras is. And add some
other ras message printing to make it more clear
and friendly as well.

Alex Sierra b635ae8744 drm/amdgpu: ih doorbell size of range changed for nbio v7.4
[Why]
nbio v7.4 size of ih doorbell range is 64 bit. This requires 2 DWords per register.

[How]
Change ih doorbell size from 2 to 4. This means two Dwords per ring.
Current configuration uses two ih rings.

Monk Liu 3aa0115d23 drm/amdgpu: cleanup all virtualization detection routine
we need to move virt detection much earlier because:
1) HW team confirms us that RCC_IOV_FUNC_IDENTIFIER will always
be at DE5 (dw) mmio offset from vega10, this way there is no
need to implement detect_hw_virt() routine in each nbio/chip file.
for VI SRIOV chip (tonga & fiji), the BIF_IOV_FUNC_IDENTIFIER is at
0x1503

2) we need to acknowledged we are SRIOV VF before we do IP discovery because
the IP discovery content will be updated by host everytime after it recieved
a new coming "REQ_GPU_INIT_DATA" request from guest (there will be patches
for this new handshake soon).

This reverts commit e01f2d4189.

VG20 did not require this workaround, as the fix is in the VBIOS.
Leave VG10/12 workaround as some older shipped cards do not have the
VBIOS fix in place, and the kernel workaround is required in those
situations

Andrey Grodzovsky 7c6e68c777 drm/amdgpu: Avoid HW GPU reset for RAS.
Problem:
Under certain conditions, when some IP bocks take a RAS error,
we can get into a situation where a GPU reset is not possible
due to issues in RAS in SMU/PSP.

Temporary fix until proper solution in PSP/SMU is ready:
When uncorrectable error happens the DF will unconditionally
broadcast error event packets to all its clients/slave upon
receiving fatal error event and freeze all its outbound queues,
err_event_athub interrupt  will be triggered.
In such case and we use this interrupt
to issue GPU reset. THe GPU reset code is modified for such case to avoid HW
reset, only stops schedulers, deatches all in progress and not yet scheduled
job's fences, set error code on them and signals.
Also reject any new incoming job submissions from user space.
All this is done to notify the applications of the problem.

v2:
Extract amdgpu_amdkfd_pre/post_reset from amdgpu_device_lock/unlock_adev
Move amdgpu_job_stop_all_jobs_on_sched to amdgpu_job.c
Remove print param from amdgpu_ras_query_error_count

v3:
Update based on prevoius bug fixing patch to properly call amdgpu_amdkfd_pre_reset
for other XGMI hive memebers.
