Do you have a test app or mesa patches that actually use this that you
could share?
Yeah.
The mesa portion is a little messy since the extension isn't registered
yet. But it can be found on the wip-high-priority branch here:
https://github.com/lostgoat/mesa.git
For a test app you can download this other project (wip-high-priority
branch as well):
https://github.com/lostgoat/Vulkan.git
Once everything is setup I run one session of the SSAO sample:
QUEUE_NUM=0 ./ssao
Then you can simultaneously run the computeparticles with or without
high priority:
sudo QUEUE_NUM=0 nice -n 20 ./computeparticles -high-priority
Or
sudo QUEUE_NUM=0 nice -n 20 ./computeparticles
Note: QUEUE_NUM is required.
If you have any issues building/running these let me know.
For reference, following are the output of these apps on my system on an
RX480:
