OverDrive mode allows users to increase the maximum SCLK and MCLK frequencies beyond the default on the GPU. However, this may not results in large performance gains if the GPU then runs into its TDP power limit. This patch adds the capability to increase the power limit of a GPU above its default maximum. This is only allowed when overdrive is enabled in the ppfeaturemask, since this is an overdrive feature. The TDPODLimit value from the VBIOS describes how how much higher the TDP should be allowed to go over its default, in percentage. v2: Moved dereference of hwmgr to after its validity check Signed-off-by: Joseph Greathouse <Joseph.Greathouse@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |
