drm/amd: Add detailed GFXOFF stats to debugfs

2022-08-16T22:17:31+00:00

Add debugfs interface to log GFXOFF statistics: - Read amdgpu_gfxoff_count to get the total GFXOFF entry count at the time of query since system power-up - Write 1 to amdgpu_gfxoff_residency to start logging, and 0 to stop. Read it to get average GFXOFF residency % multiplied by 100 during the last logging interval. Both features are designed to be keep the values persistent between suspends.

(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/amdgpu/UAPI: add new CTX OP to get/set stable pstates

2022-01-27T20:50:08+00:00

Add a new CTX ioctl operation to set stable pstates for profiling. When creating traces for tools like RGP or using SPM or doing performance profiling, it's required to enable a special stable profiling power state on the GPU. These profiling states set fixed clocks and disable certain other power features like powergating which may impact the results. Historically, these profiling pstates were enabled via sysfs, but this adds an interface to enable it via the CTX ioctl from the application. Since the power state is global only one application can set it at a time, so if multiple applications try and use it only the first will get it, the ioctl will return -EBUSY for others. The sysfs interface will override whatever has been set by this interface.

drm/amd: Expose the FRU SMU I2C bus

2022-01-27T20:49:48+00:00

Expose both SMU I2C buses. Some boards use the same bus for both the RAS and FRU EEPROMs and others use different buses. This enables the additional I2C bus and sets the right buses to use for RAS and FRU EEPROM access.
