drm/amdkfd: Fix Circular Locking Dependency in 'svm_range_cpu_invalidate_pagetables'

drm/amdkfd: Fix Circular Locking Dependency in 'svm_range_cpu_invalidate_pagetables'

[ Upstream commit fddc45026311c05a5355fd34b9dc0a1d7eaef4a2 ]

This commit addresses a circular locking dependency in the
svm_range_cpu_invalidate_pagetables function. The function previously
held a lock while determining whether to perform an unmap or eviction
operation, which could lead to deadlocks.

Fixes the below:

v2: To resolve this issue, the allocation of the process context buffer
(`proc_ctx_bo`) has been moved from the `add_queue_mes` function to the
`pqm_create_queue` function. This change ensures that the buffer is
allocated only when the first queue for a process is created and only if
the Micro Engine Scheduler (MES) is enabled. (Felix)

v3: Fix typo s/Memory Execution Scheduler (MES)/Micro Engine Scheduler
in commit message. (Lijo)

drm/amdkfd: pause autosuspend when creating pdd

[ Upstream commit 438b39ac74e2a9dc0a5c9d653b7d8066877e86b1 ]

When using MES creating a pdd will require talking to the GPU to
setup the relevant context. The code here forgot to wake up the GPU
in case it was in suspend, this causes KVM to EFAULT for passthrough
GPU for example. This issue can be masked if the GPU was woken up by
other things (e.g. opening the KMS node) first and have not yet gone to sleep.

However, if compute queue doesn't repond to preemption request in time
unmap will return without any error. In this case, only preemption error
is logged and Reset is not triggered. Call GPU reset in this case also.

drm/amdkfd: get doorbell's absolute offset based on the db_size

[ Upstream commit 367a0af43373d4f791cc8b466a659ecf5aa52377 ]

Here, Adding db_size in byte to find the doorbell's
absolute offset for both 32-bit and 64-bit doorbell sizes.
So that doorbell offset will be aligned based on the doorbell
size.

v2:
- Addressed the review comment from Felix.
v3:
- Adding doorbell_size as parameter to get db absolute offset.
v4:
Squash the two patches into one.
