| Subject: drm/amdkfd: Initialize sdma vm when creating sdma queue |
| |
| From: Xihan Zhang <xihan.zhang@amd.com> |
| |
| commit 79b066bd76d501cfe8328142153da301f5ca11d1 upstream. |
| |
| This patch fixes a bug where sdma vm wasn't initialized when |
| an sdma queue was created in HWS mode. |
| |
| This caused GPUVM faults to appear on dmesg and it is one of the |
| causes that SDMA queues are not working. |
