| Subject: drm/amd/powerplay: fix power over limit on Fiji |
| |
| From: Eric Huang <JinHuiEric.Huang@amd.com> |
| |
| commit a0aaa03062be252aacad60a776f3374dd53e3f98 upstream. |
| |
| power containment disabled only on Fiji and compute |
| power profile. It violates PCIe spec and may cause power |
| supply failed. Enabling it will fix the issue, even the |
| fix will drop performance of some compute tests. |
