From a2e435a1b0a3c2bc766d40356151610cc54b8772 Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Tue, 1 Mar 2016 16:51:58 +0900 Subject: [PATCH] drm/nouveau/fifo/gk104: take runlist target into account Bits 28:29 of RUNLIST_BASE specify the memory target of the runlist. Set it to 0x3 (SYS_MEM_NONCOHERENT) if the runlist object resides in system memory.
