| Subject: [PATCH] xf86pciBus.c: use Intel ddx only for pre-gen4 hardware |
| |
| Use intel ddx only on pre-gen4 hw, newer ones will fall back to modesetting |
| Author: Timo Aaltonen <tjaalton@debian.org> |
| |
| Instead of defaulting to the Intel driver for all Intel hardware, only |
| default it for older hardware for which it has shown to be better for. |
| |
| Others fall through to the -modesetting default. |
| |
| Upstream-Status: Pending [Debian/Fedora patch |
