Convert fdinfo format to one documented in drm-usage-stats.rst.
It turned out that the existing implementation was actually completely
nonsense. The calculated percentages indeed represented the usage of the
engine, but with varying time slices.
So 10% usage for application A could mean something completely different
than 10% usage for application B.
Completely nuke that and just use the now standardized nanosecond
interface.
v2: drop the documentation change for now, nuke percentage calculation
v3: only account for each hw_ip, move the time_spend to the ctx mgr.
v4: move general ctx changes into separate patch, rework the fdinfo to
ctx_mgr interface so that all usages are calculated at once, drop
some unecessary and dangerous refcount dance.
v5: add one more comment how we calculate the time spend

Add a AMDGPU_GEM_CREATE_DISCARDABLE flag to note that the content of a BO
doesn't needs to be preserved during eviction.
KFD was already using a similar functionality for SVM BOs so replace the
internal flag with the new UAPI.

Remove the accidental shifts on the values of RPTR_BLOCK_SIZE
in gfx_v8-v11. The bug essentially always programs the
corresponding fields to zero instead of the correct value.
The hardware clamps the min value to 5 so this resulted in a
value of 5 being programmed.

An A+A configuration on ASUS ROG Strix G513QY proves that the ASIC
reset for handling aborted suspend can't work with s2idle.
This functionality was introduced in commit daf8de0874 ("drm/amdgpu:
always reset the asic in suspend (v2)"). A few other commits have
gone on top of the ASIC reset, but this still doesn't work on the A+A
configuration in s2idle.
Avoid doing the reset on dGPUs specifically when using s2idle.
Fixes: daf8de0874 ("drm/amdgpu: always reset the asic in suspend (v2)")

MMIO/DOORBELL BOs' backing resources(bus address resources that are
used to talk to the GPU) are not managed by GTT manager, but they
are counted by GTT manager. That makes no sense.
With AMDGPU_GEM_CREATE_PREEMPTIBLE flag, such BOs will be managed by
PREEMPT manager(for preemptible contexts, e.g., KFD). Then they won't
be evicted and don't need to be pinned as well.
But we still leave these BOs pinned to indicate that the underlying
resource never moves.
