They will stop working in 4.9 and 5.2 although old behavior can _temporarily_ be enabled by adding "options DA_OLD_QUIRKS" to your kernel config.

...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).

I've installed CentOS 5.4 on my new Lenovo Ideapad S12 (Atom-based 12" notebook) and need to add a quirk to pm-suspend in order for the laptop to actually go to sleep. There's a couple of quirks that work just fine so I really don't have a preference. I found several instructions but most of them have failed me because CentOS's pm-utils is too ancient. Newer versions come with a parameter that adds the quirk to hald automatically, the CentOS version of pm-utils does not have t...

...mentioned that unloading nouveau then trying to reprobe for the audio device didn't work, but that still doesn't explain why this was implemented as an early quirk and not as something we just do before nouveau is setup.

The approach seems ok, but a subtle side-effect of MemoryRegion quirks is that we're going to trap the entire PAGE_SIZE range overlapping the quirk out to QEMU on guest access. The two registers at 0x2000 might be reserved for this purpose, but is there anything else that could be performance sensitive anywhere in that page? If so, it might be less transparent,...
