From a0aaa03062be252aacad60a776f3374dd53e3f98 Mon Sep 17 00:00:00 2001 From: Eric Huang Date: Mon, 26 Feb 2018 17:36:19 -0500 Subject: [PATCH] drm/amd/powerplay: fix power over limit on Fiji 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.
