ae6808b6f3This is new rust-written open-source drivers for nvidia newly made available in kernel 6.15, albeit quite work-in-progress and not quite sure if they are even usable yet. And, like nouveau, they would conflict if used. Not worth revbumps given users would've had to go quite out of their way to enable it manually and should know what they are getting into. It will either way propagate on kernel bumps due to requiring to rebuild nvidia-drivers. Blacklisting given "possible" that dist-kernels will enable it by default in the future albeit it is quite experimental at this stage and needs rust, so I doubt it'll happen with 6.15.x. Note nvidia-drm.fbdev=1 may or may not be able to unload it which *could* allow unblacklisting (same for nouveau), but this feels kind of fragile and we have it off by default for now. It is more typical to use fbdev=1 to unload simpledrm after using for early boot display. Technically not meaningful in nvidia-390/470.conf given nova is not usable for these old cards, but no real reason not to keep in sync. Signed-off-by: Ionen Wolkens <ionen@gentoo.org>
