Subject: [PATCH] [resend] nouveau: Disable AGP for SiS 761
Date: Wed, 30 Sep 2015 13:48:21 +0200	[thread overview]
Message-ID: <1443613701-30581-1-git-send-email-linux@rainbow-software.org> (raw)

SiS 761 chipset does not support AGP cards but has AGP capability (for
the onboard video). At least PC Chips A31G board using this chipset has
an AGP-like AGPro slot that's wired to the PCI bus. Enabling AGP will
fail (GPU lockup and software fbcon, X11 hangs).

Add support for matching just the host bridge in nvkm_device_agp_quirks
and add entry for SiS 761 with mode 0 (AGP disabled).
