<content type='text'>
[Why]
Allow user to know number of compute units (CU) that are in use at any
given moment.

[How]
Remove the keyword static for the method kgd_gfx_v9_get_cu_occupancy

Add more function pointers to amdgpu_mmhub_funcs. ASIC specific
implementation of most mmhub functions are called from a general
function pointer, instead of calling different function for
different ASIC. Simplify the code by deleting duplicate functions

<title>kernel: move use_mm/unuse_mm to kthread.c</title>

<id>9bf5b9eb232b34738800868e30bea3bad4a6a1ba</id>
<content type='text'>
Patch series "improve use_mm / unuse_mm", v2.

This series improves the use_mm / unuse_mm interface by better documenting
the assumptions, and my taking the set_fs manipulations spread over the
callers into the core API.

This patch (of 3):

Use the proper API instead.

Link: http://lkml.kernel.org/r/20200404094101.672954-1-hch@lst.de

These helpers are only for use with kernel threads, and I will tie them
more into the kthread infrastructure going forward.  Also move the
prototypes to kthread.h - mmu_context.h was a little weird to start with
as it otherwise contains very low-level MM bits.

<title>drm/amdkfd: use kiq to load the mqd of hiq queue for gfx v9 (v6)</title>

<id>35cd89d5a658dc26687a7a6909d35fee19a6b173</id>
<content type='text'>
There is an issue that CP will check the HIQ queue to be configured and mapped
with KIQ ring, otherwise, it will be unable to read back the secure buffer while
the gfxoff is enabled even with trusted IP blocks.

v1 -&gt; v2:
- Fix to remove surplus set_resources packets.
- Fill the whole configuration in MQD.
- Change the author as Aaron because he addressed the key point of this issue.
- Add kiq ring lock.

v2 -&gt; v3:
- Free the lock while in error return case.
- Remove the programming only needed by the queue is unmapped.

v3 -&gt; v4:
- Remove doorbell programming because it's used for restarting queue.
- Remove CP scheduler programming because map_queue packet will handle this.

v4 -&gt; v5:
- Remove cp_hqd_active because mec ucode will enable it while use map_queues.
- Revise goto out_unlock.
- Correct the right doorbell offset for HIQ that kfd driver assigned in the
  packet.

v5 -&gt; v6:
- Merge Arcturus fix into this patch because it will get oops in Arcturus
  platform.

[How]
TLB invalidate functions removed from the different amdkfd_gfx_v*

The SOC15_REG_OFFSET() macro needs to dereference adev-&gt;reg_offset[IP]
pointer, which is sometimes NULL when there are fewer than 8 sdma engines.
Avoid that by not initializing the array regardless.
