<pre class="moz-quote-pre" wrap="">This patch adds the following functionality:
- Check the queue preemption status on all XCDs in a partition
for GFX 9.4.3.
- Update the queue preemption debug message to print the queue
doorbell id for which preemption failed.
- Change the signature of check preemption failed function to
return a bool instead of uint32_t and pass the MQD manager
as an argument.
