Am 21.02.22 um 17:45 schrieb Arunpravin: > Move shared vram inline functions and structs > into a header file > > Signed-off-by: Arunpravin <Arunpravin.PaneerSelvam@amd.com> Patches #1-#3 haven been pushed to drm-misc-next. For this one it might be better to squash that into commit #5 as well since this is otherwise unused. Might be a good idea to move the vram_mgr structur and function from amdgpu_ttm.h over to this file as well.
