[Why]
We have logging methods for printing hardware state for newer ASICs
but no way to trigger the log output.
[How]
Add support for triggering the output via writing to a debugfs file
entry. Log output currently goes into dmesg for convenience, but
accessing via a

[Why]
Logging hardware state can be done by triggering a write to the
debugfs file. It would also be useful to be able to read the hardware
state from the debugfs file to be able to generate a clean log without
timestamps.

[Why]
Now that we "scale" time delays correctly on Maximus (as of diags svn
r170115), the forced "35 ms" wait time now becomes 35 ms * 500 = 17.5
seconds, which is far too long. Even having to repeat polling a
register once causes excessive delays on Maximus.

Hi Dave,
Fixes for 4.19:

Hi all,
Oded has offered to make me co-maintainer of KFD, as he's super busy at
work and less responsive than he used to be.
At the same time we're about to send out the first patches to merge KFD
and AMDGPU into a single kernel module.
With that in mind I'd like to propose to upstream KFD

I continue to work for bulk moving that based on the proposal by Christian.
Background:
amdgpu driver will move all PD/PT and PerVM BOs into idle list. Then move all of
them on the end of LRU list one by one. Thus, that cause so many BOs moved to
the end of the LRU, and impact performance

Hi all,
I think it's time to brainstorm a bit about the gitlab migration. Basic reasons:

- gitlab will allow us to add committers on our own, greatly
simplifying that process (and
