04:55 df00z: Is it worth trying the nova driver yet? If nouveau + zink is unstable
04:55 df00z: For a 3080
04:58 orowith2os[d]: df00z: Nova is a kernel driver, not userspace. NVK + Zink runs on top of either the nouveau kernel driver, or Nova. And there's nouveau-gl, the gallium driver, that was used before NVK+Zink came to be.
05:00 orowith2os[d]: That being said, it depends on if you mean the graphics side of things being unstable or you're having issues more in hardware stuff (displays, etc, which would be the kernel driver).
05:01 orowith2os[d]: To my knowledge people here have been running nvk + Zink on Turing GPUs for a while and it's gotten a fair bit of testing, enough to run actual desktops and games.
05:01 orowith2os[d]: Just make sure your system is up to date in the kernel and mesa.
22:11 dylanetaft: ia nova usable on git head kernels for wayland? nouveu and zink are super unstable on ampere altra
22:12 dylanetaft: also happy holidays
22:12 mhenning[d]: no, nova is not far enough along to draw anything to the screen yet
22:12 mhenning[d]: and happy holidays 🙂
22:14 dylanetaft: ahh ok for now using the drm env variable to force use of nouveau for gl which is stable
22:16 mhenning[d]: what card are you on?
22:17 dylanetaft: 3080
22:17 mhenning[d]: we do care about regressions compared to the nouveau gl driver, although I don't think any of the devs have access to an ampere altra system to test
22:17 dylanetaft: https://gitlab.freedesktop.org/mesa/mesa/-/issues?sort=created_date&state=opened&search=Ampere+altra&first_page_size=20&show=eyJpaWQiOiIxMzgxNCIsImZ1bGxfcGF0aCI6Im1lc2EvbWVzYSIsImlkIjoxMzczMDN9
22:18 dylanetaft: its probably related to a cpu errata, pcie writes have to be aligned or stuff gets corrupt
22:20 mhenning[d]: Ah, right. I'm not really sure what to do about that one.
22:21 dylanetaft: idk what nvidia does in their binary driver
22:22 dylanetaft: since theyre working heavily on nova my hope is itll get whatever magic sauce is needed
22:26 mhenning[d]: yeah. If it's a kernel-level workaround it should be present somewhere in the nvidia/open-gpu-kernel repo
22:31 dylanetaft: oh interesting
22:37 dylanetaft: they do have a workaround in there, pcie write combining is disabled in the open driver
