My bisect resulted in the same conclusion, that the problem began with
edad8312cbbf9a33c86873fc4093664f150dd5c1.
That commit has a LOT of changes, so I'm having problems following what
might be relevant, so in case Hawking or Dennis have any insight they
could contribute towards letting us know wh
I actually *just* finished my bisect, and arrived at the same
conclusion. The hang appears to be introduced in
edad8312cbbf9a33c86873fc4093664f150dd5c1.
There are some conflicts with an automatic `git revert`, so I'm picking
through the changes now to fully understand what happened and come up
wit

In gfx_v10_0_sw_fini the KIQ ring gets freed. Wouldn't that be the right
place to stop the KIQ? Otherwise KIQ will hang as soon as someone
allocates the memory that was previously used for the KIQ ring buffer
and overwrites it with something that's not a valid PM4 packet.

what:
the MQD's save and restore of KCQ (kernel compute queue)
cost lots of clocks during world switch which impacts a lot
to multi-VF performance
how:
introduce a paramter to control the number of KCQ to avoid
performance drop if there is no kernel compute queue needed
notes:
this paramter only
KIQ will hang if we try below steps:
modprobe amdgpu
rmmod amdgpu
modprobe amdgpu sched_hw_submission=4
the cause is that due to KIQ is always living there even
after we unload KMD thus when doing the realod of KMD
KIQ will crash upon its register programed with different
values with the previous
