[PATCH 6/7] drm/amd/pp: Export load_firmware interface

Rex Zhu Rex.Zhu at amd.com
Wed Sep 26 12:50:48 UTC 2018


Export this interface for the AMDGPU_FW_LOAD_SMU type.
gfx/sdma can request smu to load firmware.

Split the smu7/8_start_smu function into two functions
1. start_smu, used for load smu firmware in smu7/8 and
   check smu firmware version.
2. request_smu_load_fw, used for load other ip's firmware
   on smu7/8 and add firmware loading staus check.
