[PATCH libdrm v2 2/2] amdgpu/test: Fix deadlock tests for AI and RV v2

[Andrey Grodzovsky]

Seems like AI and RV requires uncashed memory mapping to be able
to pickup value written to memory by CPU after the WAIT_REG_MEM
command was already launched.
.
Enable the test for AI and RV.

v2:
Update commit description.
