The purpose of this KFDTest is to investigate the behaviour of an SDMA queue when an invalid memory address is used. v2: Don't wait for SDMA queue to finish - it won't finish because of the gpuvm fault. v3: Create kfd event before SDMA queue submission. This fix the issue that gpuvm fault happens earlier than kfd event is created then KFD exception handler can't find the kfd event (to wake up kfd test) v4: Instead of using 0x12345678 as the invalid VA, map one page of FB to gpu and unmap it. Use the mapped GPUVA as the invalid address Change-Id: I58af1511f75d869adddede302b238c2725f3fe5a Signed-off-by: Ori Messinger <Ori.Messinger@amd.com> Signed-off-by: Oak Zeng <Oak.Zeng@amd.com>
