From 8e39abff45888a54b3d9dc20434940dabeda077f Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 1 Nov 2017 03:56:19 +1000 Subject: [PATCH] drm/nouveau/mmu/gp100,gp10b: implement vmm on top of new base Adds support for: - Selection of old/new-style page table layout (GP100MmuLayout=0/1). - System-memory PDs. New layout disabled by default for the moment, as we don't have a backend that can handle it yet.
