| Subject: [PATCH] CHROMIUM: drm/msm: Enable eviction by default |
| |
| Upstream I took the conservative approach of not enabling eviction by |
| default. Because the various generations of supported devices are |
| paired with at least three different possible iommus, I wanted a chance |
| to get some more testing on older devices before flipping the switch. |
| |
| For CrOS this is not a constraint, so enable by default. If we uncover |
| any issues we can revert this commit. |
