From e69dae85c90b3e07ed5538a8ad8a7ee807fbbf64 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 1 Nov 2017 03:56:19 +1000 Subject: [PATCH] drm/nouveau/bar/nv50,g84: drop mmu invalidate Will already be done by MMU as a result of the PT writes that occur during BAR2 bootstrapping. This is likely just a left-over from the days when it was hardcoded.
