2021-12-14drm/amdgpu: move smu_debug_mask to a more proper placeEvan Quan1-0/+8
As the smu_context will be invisible from outside(of power). Also, the smu_debug_mask can be shared around all power code instead of some specific framework(swSMU) only.

2021-11-22drm/amd/pm: avoid duplicate powergate/ungate settingEvan Quan1-0/+8
Just bail out if the target IP block is already in the desired powergate/ungate state. This can avoid some duplicate settings which sometimes may cause unexpected issues.

2021-08-16drm/amd/pm: drop the unnecessary intermediate percent-based transitionEvan Quan1-4/+4
Currently, the readout of fan speed pwm is transited into percent-based and then pwm-based. However, the transition into percent-based is totally unnecessary and make the final output less accurate.

2021-07-01drm/amdgpu: add a mutex for the smu11 i2c bus (v2)Alex Deucher1-0/+1
So we lock software as well as hardware access to the bus. v2: fix mutex handling. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Luben Tuikov <luben.tuikov@amd.com>
2020-09-29drm/amd/powerplay: add one sysfs file to support the feature to modify gfx clock on Raven/Raven2/Picasso APU.Xiaojian Du1-0/+4
This patch is to add one sysfs file -- "pp_od_clk_voltage" for Raven/Raven2/Picasso APU, which is only used by dGPU like VEGA10. This sysfs file supports the feature to modify gfx engine clock(Mhz units), it can be used to configure the min value and the max value for gfx clock limited in the safe range. Command guide: echo "s level clock" > pp_od_clk_voltage s - adjust teh sclk level level - 0 or 1, "0" represents the min value, "1" represents the max value clock - the clock value(Mhz units), like 400, 800 or 1200, the value must be within the OD_RANGE limits. Example: $ cat pp_od_clk_voltage OD_SCLK: 0: 200Mhz 1: 1400Mhz OD_RANGE: SCLK: 200MHz 1400MHz $ echo "s 0 600" > pp_od_clk_voltage $ echo "s 1 1000" > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 600Mhz 1: 1000Mhz OD_RANGE: SCLK: 200MHz 1400MHz Signed-off-by: Xiaojian Du <Xiaojian.Du@amd.com> Reviewed-by: Kevin Wang <kevin1.wang@amd.com> Reviewed-by: Huang Rui <ray.huang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-08-14drm/amd/pm: optimize the power related source code layoutEvan Quan1-0/+565
The target is to provide a clear entry point(for power routines). Also this can help to maintain a clear view about the frameworks used on different ASICs. Hopefully all these can make power part more friendly to play with.
