[PATCH 1/4] drm/amd/pp: Add new smu callback function

[jinhuieric.huang@xxxxxxx (Eric Huang)]

Hi Rex,

Why don't you use function smum_populate_requested_graphic_levels() 
which is doing exactly the same thing as the function you add ?

And in old power profile setting function 
smu7_set_power_profile_state(), we implement this:

if (hwmgr->chip_id == CHIP_FIJI) {
 Â Â Â  Â Â Â  if (request->type == AMD_PP_GFX_PROFILE)
 Â Â Â  Â Â Â  Â Â Â  smu7_enable_power_containment(hwmgr);
 Â Â Â  Â Â Â  else if (request->type == AMD_PP_COMPUTE_PROFILE)
 Â Â Â  Â Â Â  Â Â Â  smu7_disable_power_containment(hwmgr);
 Â Â Â  }

This should be merged into your new power profile setting.

Regards,
Eric
