From: Andres Rodriguez Date: Fri, 3 Feb 2017 21:17:15 +0000 (-0500) Subject: drm/radeon: take ownership of pipe initialization X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d59095f7dd8810e67bdad7a65131903646ebc444;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/radeon: take ownership of pipe initialization Take ownership of pipe initialization away from KFD. Note that hpd_eop_gpu_addr was already large enough to accomodate all pipes.
