No idea, I mean that's for GFX7/8 which was released between 2013
and 2017.<br>

My educated guess is that you could create a test where you write
something to VRAM or GTT with a shader and than in the interrupt
handler try to observer if you can see those values with the CPU.<br>
<br>
If those values aren't visible with the CPU then you have either a
cache flushing issue or your CPU and/or PCIe root complex is
incorrectly reordering writes and interrupts.<br>
