      amdgpu/pm: Add emit_clock_levels calls · c8cb19c7
      由 Darren Powell 提交于 
         (v4)
     Modifications to satisfy checkpatch --strict
   (v3)
     Rewrote patchset to order patches as (API, hw impl, usecase)

     - modified amdgpu_get_pp_od_clk_voltage to try
       amdgpu_dpm_emit_clock_levels and fallback to
       amdgpu_dpm_print_clock_levels if emit is not implemented.
     - modified amdgpu_get_pp_dpm_clock to try
       amdgpu_dpm_emit_clock_levels and fallback to
       amdgpu_dpm_print_clock_levels if emit is not implemented.
     - Newline is printed to buf if no output produced

      drm/amdgpu/UAPI: add new CTX OP to get/set stable pstates · 8cda7a4f
      由 Alex Deucher 提交于 
      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.

      amdgpu/pm: Create shared array of power profile name strings · 3867e370
      由 Darren Powell 提交于 
       == Description ==
 All the power profile modes use the same strings (or a subset of)
 Creating a public array of the strings will allow sharing rather than
 duplicating for each chip
 First patch only implements change for navi10, followup with other chips

 == Changes ==
 Create a declaration of the public array in kgd_pp_interface.h
 Define the public array in amdgpu_pm.c
 Modify the implementaiton of navi10_get_power_profile_mode to use new array

 == Test ==
 LOGFILE=pp_profile_strings.test.log

 AMDGPU_HWMON=`ls -la /sys/class/hwmon | grep $AMDGPU_PCI_ADDR | awk '{print $9}'`
