This works perfectly fine if I use MMIO writes. But KIQ breaks when done
over KIQ, which is why I find it weird.

We ran into a similar problem when we played with priorities on KFD
queues. You can't change an MQD of a currently mapped queue. To change a
queue priority we need to unmap it, update the MQD, and then map it again.
I wonder if a queue can change its own priority by using register write
commands in the queue itself.

Hey Everyone,
On one of the previous comments for this series I received feedback that
the register programming should be done through the KIQ. This series has
the relevant changes.
However, register writes that require an srbm_select are not working
correctly. The effect is as if the write never happened.
Maybe I'm just doing something silly or dumb in here, but I can't really
see it. Possibly the way I try to perform the srbm_select for KIQ?
Any feedback on this issue is appreciated.
I think to make this work, you'd probably need to do is unmap the
queue, update the priority in the mqd, and then map it again. It's
probably more efficient to use runlists, but that is a lot of work.
