[Why] Before this patchset, navi10 users could not utilize the overdrive functionality. This prevented them from overclocking, overvolting, or undervolting their cards. [How] Similar to the vega20 implementation, add the pp_od_clk_voltage interface to the navi10 powerplay table. [Possible Alternatives] This could also be done more generically in smu_v11_0 code, but would require more significant changes to the vega20 code, and feature-gating based on chip capabilities in the smu to disable overdrive for arcterus. I chose this path so as not to completely refactor the vega20 side of things, and introduce SMU code which would not play nicely with new ASICs. v2: rebase off latest code, and remove an incorrect bounds check Matt Coffin (3): drm/amdgpu/navi10: implement sclk/mclk OD via pp_od_clk_voltage drm/amdgpu/navi10: implement GFXCLK_CURVE overdrive drm/amdgpu/navi10: Implement od clk printing drivers/gpu/drm/amd/powerplay/inc/smu_v11_0.h | 2 + drivers/gpu/drm/amd/powerplay/navi10_ppt.c | 282 ++++++++++++++++++ drivers/gpu/drm/amd/powerplay/navi10_ppt.h | 2 + drivers/gpu/drm/amd/powerplay/smu_v11_0.c | 27 ++ 4 files changed, 313 insertions(+) -- 2.23.0 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
