| Subject: drm/radeon: fix cursor corruption on DCE6 and newer |
| |
| From: Jerome Glisse <jglisse@redhat.com> |
| |
| commit e521a29014794d139cca46396d1af8faf1295a26 upstream. |
| |
| Aruba and newer gpu does not need the avivo cursor work around, |
| quite the opposite this work around lead to corruption. |
| |
| agd5f: check DCE6 rather than ARUBA since the issue is DCE |
| version specific rather than family specific. |
