From 91681302d0308a70aece883c3b56a18f9a44041f Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 27 Aug 2016 19:46:25 -0400 Subject: [PATCH] nouveau: allow NV3x's to be used with nouveau_vieux NV34 and possibly other NV3x hardware has the capability of exposing the NV25 graph class. This allows forcing nouveau_vieux to be used instead of the gallium driver, primarily for testing purposes. (Among other things, NV2x only ever came as AGP or inside an Xbox, never PCI/PCIe).
