amdgpu/pm: Implement new API function "emit" that accepts buffer base and write offset

2022-02-02T23:27:58Z

(v3) Rewrote patchset to order patches as (API, hw impl, usecase) - added API for new power management function emit_clk_levels This function should duplicate the functionality of print_clk_levels, but this solution passes the buffer base and write offset down the stack. - new powerplay function emit_clock_levels, implemented by smu_emit_ppclk_levels() This function parallels the implementation of smu_print_ppclk_levels and calls emit_clk_levels, and allows the returns of errors - new helper function smu_convert_to_smuclk called by smu_print_ppclk_levels and smu_emit_ppclk_levels Signed-off-by: Darren Powell Reviewed-By: Evan Quan Signed-off-by: Alex Deucher

drm/amd/pm: correct the checks for fan attributes support

2022-01-14T22:51:15Z

On functionality unsupported, -EOPNOTSUPP will be returned. And we rely on that to determine the fan attributes support. Fixes: 79c65f3fcbb128 ("drm/amd/pm: do not expose power implementation details to amdgpu_pm.c") Signed-off-by: Evan Quan Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd/pm: do not expose the smu_context structure used internally in power

2022-01-14T22:51:14Z

This can cover the power implementation details. And as what did for powerplay framework, we hook the smu_context to adev->powerplay.pp_handle. Signed-off-by: Evan Quan Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd/pm: optimize the amdgpu_pm_compute_clocks() implementations

2022-01-14T22:51:14Z

Drop cross callings and multi-function APIs. Also avoid exposing internal implementations details. Signed-off-by: Evan Quan Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd/pm: create a new holder for those APIs used only by legacy ASICs(si/kv)

2022-01-14T22:51:14Z

Those APIs are used only by legacy ASICs(si/kv). They cannot be shared by other ASICs. So, we create a new holder for them. Signed-off-by: Evan Quan Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd/pm: do not expose implementation details to other blocks out of power

2022-01-14T22:51:14Z

Those implementation details(whether swsmu supported, some ppt_funcs supported, accessing internal statistics ...)should be kept internally. It's not a good practice and even error prone to expose implementation details. Signed-off-by: Evan Quan Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

amdgpu/pm: Create shared array of power profile name strings

drm/amd/pm: drop the unnecessary intermediate percent-based transition

2021-08-16T19:35:56Z

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. Signed-off-by: Evan Quan Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd/pm: Add u64 throttler status field to gpu_metrics

2021-06-10T15:44:25Z

This patch set adds support for a new ASIC independant u64 throttler status field (indep_throttle_status). Piggybacks off the gpu_metrics_v1_3 bump and similarly bumps gpu_metrics_v2 version (to v2_2) to add field.
