Subject: [PATCH] drm/amd/powerplay: fix power over limit on Fiji
Git-commit: a0aaa03062be252aacad60a776f3374dd53e3f98
Patch-mainline: v4.16-rc4
References: bsc#1051510
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.
