From ab1fd9c1cc47e0b63abb374a3b9ab1151d705848 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 31 Mar 2016 16:07:38 -0400 Subject: [PATCH] drm/amdgpu/gmc: move vram type fetching into sw_init commit d1518a1db31a25682ea09c4b135fa72d9883be42 upstream. early_init gets called before atom asic init so on non-posted cards, the vram type is not initialized.
