drm/amd/pp: Print out voltage/clock range in sysfs

2018-05-15T18:43:48+00:00

when user cat pp_od_clk_voltage add display info about the sclk/mclk/vddc range that user can overdrive output as: OD_SCLK: 0: 300MHz 900mV 1: 400MHz 912mV 2: 500MHz 925mV 3: 600MHz 937mV 4: 700MHz 950mV 5: 800MHz 975mV 6: 900MHz 987mV 7: 1000MHz 1000mV OD_MCLK: 0: 300MHz 900mV 1: 1500MHz 912mV OD_RANGE: SCLK: 300MHz 1200MHz MCLK: 300MHz 1500MHz VDDC: 700mV 1200mV also 1. remove unnecessary whitespace before a quoted newline 2. change unit of frequency Mhz to MHz Reviewed-by: Alex Deucher Signed-off-by: Rex Zhu Signed-off-by: Alex Deucher

drm/amd/pp: Remove struct pp_gpu_power

2018-05-15T18:43:18+00:00

Currently smu only calculate average gpu power in real time. for vddc/vddci/max power, User need to set start time and end time, firmware can calculate the average vddc/vddci/max power. but the type of return values is not unified. For Vi, return type is uint. For vega, return type is float. so this struct can't be suitable for all asics. Acked-by: Alex Deucher Signed-off-by: Rex Zhu Signed-off-by: Alex Deucher

drm/amdgpu: Remove wrapper layer of smu ip functions

2018-03-15T14:57:50+00:00

1. delete amdgpu_powerplay.c used for wrapping smu ip functions 2. delete struct pp_instance, 3. make struct hwmgr as the smu hw handle. Reviewed-by: Alex Deucher Reviewed-by: Evan Quan Signed-off-by: Rex Zhu Signed-off-by: Alex Deucher

drm/amd/pp: Add auto power profilng switch based on workloads (v2)

2018-03-07T21:10:09+00:00

Add power profiling mode dynamic switch based on the workloads. Currently, support Cumpute, VR, Video, 3D,power saving with Cumpute have highest prority, power saving have lowest prority. in manual dpm mode, driver will stop auto switch, just save the client's requests. user can set power profiling mode through sysfs. when exit manual dpm mode, driver will response the client's requests. switch based on the client's prority. v2: squash in fixes from Rex Reviewed-by: Evan Quan Signed-off-by: Rex Zhu Signed-off-by: Alex Deucher

The gfx/compute profiling mode switch is only for internally test. Not a complete solution and unexpectly upstream. so revert it. Reviewed-by: Evan Quan Acked-by: Christian König Signed-off-by: Rex Zhu Signed-off-by: Alex Deucher
