82a829dc8c drm/amdgpu: fix calltrace during kmd unload(v3)
issue:
kernel would report a warning from a double unpin
during the driver unloading on the CSB bo

why:
we unpin it during hw_fini, and there will be another
unpin in sw_fini on CSB bo.

fix:
actually we don't need to pin/unpin it during
hw_init/fini since it is created with kernel pinned,
we only need to fullfill the CSB again during hw_init
to prevent CSB/VRAM lost after S3

v2:
get_csb in init_rlc so hw_init() will make CSIB content
back even after reset or s3

v3:
use bo_create_kernel instead of bo_create_reserved for CSB
otherwise the bo_free_kernel() on CSB is not aligned and
would lead to its internal reserve pending there forever

take care of gfx7/8 as well

58f46d4b65 drm/amdgpu: disallow direct upload save restore list from gfx driver
Direct uploading save/restore list via mmio register writes breaks the security
policy. Instead, the driver should pass s&r list to psp.

For all the ASICs that use rlc v2_1 headers, the driver actually upload s&r list
twice, in non-psp ucode front door loading phase and gfx pg initialization phase.
The latter is not allowed.

VG12 is the only exception where the driver still keeps legacy approach for S&R
list uploading. In theory, this can be elimnated if we have valid srcntl ucode
for VG12.

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.
