f59548c882 drm/amdgpu:fix NULL pointer access during drv remove
NULL pointer is because original logic will step into
set_pde_pte() even after the gart.ptr is freed due to
there are twice gart_unbind() on all gart area.

also, there are other minor fixes:
1,since gart_init only create dummy page, the corresponding
gart_fini shouldn't do more like unbinding all GART, this is
unnecessary because in driver fini stage all GART unbinding
had already been done during each IP's SW_FINI (GMC's
SW_FINI is the last one called), so remove the step
for the GART unbinding in gart_fini().

2,gart_fini() is already invoked during each GMC IP's gart_fini
routine,e.g. gmc_vx_0_gart_fini(), so no need to manually
call it during ttm_fini().

3,amdgpu_gem_force_release() should be put ahead of
amdgpu_vm_manager_fini()

c79ee7d8c6 drm/amdgpu:cleanup GMC & gart garbage function
for gart_ram_alloc/free, they are never used in driver thus
ripe them out totally.

for gart_vram_pin/unpin, they are not needed becuase we can
use bo_creat_kernel/free to replace the original manual way
in the gart_vram_alloc/free, thus gart_vram_pin/unpin can
also be riped out.

c1fe75c9e4 drm/amd/amdgpu: fix UVD mc offsets
When UVD bo is created, its size is based on the information from firmware
header (ucode_size_bytes). The same value should be be used when programming
UVD mc controller offsets, otherwise it can happen that
(mmUVD_VCPU_CACHE_OFFSET2 + mmUVD_VCPU_CACHE_SIZE2) will point
AMDGPU_GPU_PAGE_SIZE bytes after the UVD bo end.

Second issue is that when programming the mmUVD_VCPU_CACHE_SIZE0 register,
AMDGPU_UVD_FIRMWARE_OFFSET should be taken into account. If it isn't,
(mmUVD_VCPU_CACHE_OFFSET2 + mmUVD_VCPU_CACHE_SIZE2) will always point
AMDGPU_UVD_FIRMWARE_OFFSET bytes after the UVD bo end.

v2: move firmware size calculation into macro definition
v3: align firmware size to the gpu page size

original data on the VRAM.

Refine the code to create bo on VRAM domain directly and then remove
and re-create mem node to the exact position before bo_pin. This can
avoid breaking the data and will not cause eviction.

48f05f2955 amd/scheduler:imple job skip feature(v3)
jobs are skipped under two cases
1)when the entity behind this job marked guilty, the job
poped from this entity's queue will be dropped in sched_main loop.

2)in job_recovery(), skip the scheduling job if its karma detected
above limit, and also skipped as well for other jobs sharing the
same fence context. this approach is becuase job_recovery() cannot
access job->entity due to entity may already dead.

v2:
some logic fix

v3:
when entity detected guilty, don't drop the job in the poping
stage, instead set its fence error as -ECANCELED

in run_job(), skip the scheduling either:1) fence->error < 0
or 2) there was a VRAM LOST occurred on this job.
this way we can unify the job skipping logic.

with this feature we can introduce new gpu recover feature.
