drm/amd/pm: correct the default DriverSmuConfig table settings

2022-02-16T21:57:34+00:00

For Some ASICs, with the PMFW default settings, we may see the
power consumption reported via metrics table is "Very Erratic".
With the socket power alpha filter set as 10/100ms, we can correct
that issue.

drm/amd/pm: add missing prototypes to amdgpu_dpm_internal

2022-02-07T23:03:50+00:00

Include the header with the prototype to silence the following clang

Besides that, remove the duplicated prototype of the function
amdgpu_dpm_get_vblank_time in order to keep the consistency of the
headers.

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

2022-02-02T23:27:58+00:00

   (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

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.
