From f94773b9f5ecd1df7c88c2e921924dd41d2020cc Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 18 Mar 2017 16:23:10 -0400 Subject: drm/nouveau/mmu/nv4a: use nv04 mmu rather than the nv44 one The NV4A (aka NV44A) is an oddity in the family. It only comes in AGP and PCI varieties, rather than a core PCIE chip with a bridge for AGP/PCI as necessary. As a result, it appears that the MMU is also non-functional. For AGP cards, the vast majority of the NV4A lineup, this worked out since we force AGP cards to use the nv04 mmu. However for PCI variants, this did not work. Switching to the NV04 MMU makes it work like a charm. Thanks to mwk for the suggestion. This should be a no-op for NV4A AGP boards, as they were using it already.
