| Subject: [PATCH] drm/amdgpu: allow direct upload save restore list for raven2 |
| |
| commit eebc7f4d7ffa09f2a620bd1e2c67ddd579118af9 upstream. |
| |
| It will cause modprobe atombios stuck problem in raven2 if it doesn't |
| allow direct upload save restore list from gfx driver. |
| So it needs to allow direct upload save restore list for raven2 |
| temporarily. |
