From: Ben Skeggs Date: Thu, 11 Sep 2014 12:59:13 +0000 (+1000) Subject: drm/nouveau/pwr/memx: rename fb off/on to block/unblock X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=630a6a466b5afff0ec5824e6f62e5dba15812256;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/nouveau/pwr/memx: rename fb off/on to block/unblock More accurate as to the function of the opcodes. Not only is FB disabled, but the host is prevented from touching the GPU. An upcoming patch for Kepler will also halt PFIFO (as NVIDIA does).
