[PATCH 3/5] drm/amdgpu: Extract the function of fw loading out of powerplay

Rex Zhu Rex.Zhu at amd.com
Tue Oct 9 12:43:41 UTC 2018


So there is no dependence between gfx/sdma/smu.
and for Vi, after IH hw_init, driver load all the smu/gfx/sdma
fw. for AI, fw loading is controlled by PSP, after psp hw init,
we call the function to check smu fw version.
