Phoronix: Linux 6.7-rc1 Released With NVIDIA GSP & Bcachefs While Itanium IA-64 Retired

After a very exciting two weeks, the merge window for Linux 6.7 is now wrapped up and Linus Torvalds has published Linux 6.7-rc1 as the first release candidate leading up to the stable release around the end of the calendar year...

I still think 6.7 will be LTS. It is within 2023.

WIll be a great kernel overall.

I still think 6.7 will be LTS. It is within 2023.

Seems unlikely to me. A release with more code churn than usual and a much anticipated new file system in an experimental state probably isn't something they want to maintain for 2 years.

I tried nouveau with last linux-firmware and this kernel with a rtx 4070 but get freeze on the tty, i can use my keyboard but the screen is freeze, when i blacklist nouveau screen dont freeze.

I managed to find some time and try it on my PC with RTX 3060. I installed Arch Linux and then compiled kernel 6.7 with mesa and libdrm from git. After enabling GSP support everything was working fine and experience was pretty nice - no crashes, artifacts or hangs. I've made some quick tests to check how is it working and tl;dr - Yes, it is much faster and no, it won't replace proprietary drivers for now.

I tried 3 benchmark tools (Unigine Valley, glmark2 and vkmark) and here are the results. Note: everything was running in windowed mode in 1280x720. Unigine Valley quality was set to Medium (for some reason Nouveau crashes on better settings).

Unigine Valley:
Nouveau without GSP: 531 Score, 12.7 FPS, 8.7 Min FPS, 18.4 Max FPS
Nouveau with GSP: 1938 Score, 46.3 FPS, 29.2 Min FPS, 67.0 Max FPS
NVIDIA: 9824 Score, 234.8 FPS, 53.1 Min FPS, 374.1 Max FPS

glmark2:
Nouveau without GSP: 322 Score
Nouveau with GSP: 5675 Score
NVIDIA: 6231 Score

vkmark:
Nouveau without GSP: 269 Score
Nouveau with GSP: 1399 Score
NVIDIA: 13236 Score

So yeah, there is still a lot of room for improvements on Nouveau side. I heard that Nouveau OpenGL support is not in really good shape (for my RTX 3060 OpenGL version was limited to 4.3) so that would probably explain OpenGL performance. As for the Vulkan, NVK is still experimental so performance is justified as well. I also wanted to try Zink but NVK is not there yet (applications running on Zink complains that Vulkan driver is missing needed features and crashes). Now since reclocking is not an issue anymore I guess we will get more improvements in near future.

I compiled last mesa and libdrm but same result, i have this in dmesg when i modprobe nouveau:

[ 22.501185] nouveau 0000:01:00.0: vgaarb: deactivate vga console

kripteks: can you add

debug="gsp=debug" config=NvGspRm=1

to the nouveau.ko command line when you load it? That will provide better debugging logs.
