Subject: drm/amdgpu/gfx10: new approach to load gfx10 me fw (v4)
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8825af65ffc1d9eb3fafd8841a741c4f5bef88c8;p=openwrt%2Fstaging%2Fblogic.git

drm/amdgpu/gfx10: new approach to load gfx10 me fw (v4)

gfx10 allows to only upload me jumptable while save the whole
me image at gtt memory.

v2: program CP_ME_IC_BASE_CNTL to default value
v3: switch to use amdgpu_bo_create_reserved to create me fw bo
v4: split common code from gfx10 code
