drm/amd/powerplay: Fix enum mismatch

2018-06-05T09:46:11Z

commit 42b5122e828a6ccd9952ad3116343dc032d33efe upstream. In several locations the driver uses AMD_CG_STATE_UNGATE (type enum amd_clockgating_state) instead of AMD_PG_STATE_UNGATE (type enum amd_powergating_stat) and vice versa. Both constants have the same value, so this doesn't cause any problems, but we still want to pass the correct type. Fixing the mismatch resolves multiple warnings like this when building with clang: drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/cz_clockpowergating.c:169:7: error: implicit conversion from enumeration type 'enum amd_powergating_state' to different enumeration type 'enum amd_clockgating_state' [-Werror,-Wenum-conversion] AMD_PG_STATE_UNGATE); Reviewed-by: Guenter Roeck Signed-off-by: Matthias Kaehlcke Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amd/powerplay: fix power over limit on Fiji

2018-02-28T20:17:11Z

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. Signed-off-by: Eric Huang Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

treewide/trivial: Remove ';;$' typo noise
