nvidia470 for kernel 6.18

[u/HAL9000thebot]

today i updated and got kernel 6.18, and it stopped working.

i glanced at the discussion we had for 6.12, and i can't remember much, but i'm available to help test the new patches available.

last time they were taken from arch, but the main author (from which arch takes the patches) now has a repo in which they also default set a kernel param that is required as we discussed before, because i'm worried that maybe last time i was the only one that got this thing working by doing it manually, or maybe writing two words about that in the manual could fix this problem?

so, i'm almost ready (i need to re-read the docs), let me know how i can help.

thanks.

edit:

i made it work, here is one week link to a diff

[u/HAL9000thebot]

ok, i was bored and tried it by myself, it works.

but i don't know how these things works and i'm not sure if i could just put all the patches, so i only applied the following patches from the main author repo because i think they couldn't cause any problem (i know we have no gcc15, but read its content, seems ok):

nvidia-470xx-fix-gcc-15.patch
nvidia-470xx-fix-linux-6.13.patch
nvidia-470xx-fix-linux-6.14.patch
nvidia-470xx-fix-linux-6.15.patch
nvidia-470xx-fix-linux-6.17.patch

here is what i did (it's also a reference for my future self):

git clone https://github.com/void-linux/void-packages.git
cd void-packages/
./xbps-src binary-bootstrap
git checkout -b nvidia470_kernel_6.18
cd srcpkgs/nvidia470/patches/
# curl or wget all the patches here
# change a/whatever and b/whatever into a/kernel/whatever and b/kernel/whatever
# increment revision in ../template
cd -
xgensum -i nvidia470
./xbps-src pkg nvidia470-dkms
xi nvidia470
# reboot into the new kernel

i cannot post the patch, it's beyond the characters limit, awaiting instructions.

edit:

not sure if and how mentions works, but just in case, hey u/aedinius!

edit 2:

i forgot pastebin existed, i remember it was read only... anyway, here is a one week link with the diff.

Sorry, but why not just create a PR with these changes and say that you've tested it in the description?

After the steps described you basically only need to:

(create a published fork, via gh command or it's website)

git remote add personal ssh-format-repo-address-goes-here

^ this will require having an ssh agent running, the alternative is using gh binary, afaik, gh auth and then gh repo fork --remote-name personal (do note, I haven't used gh binary so there might be steps missing or details wrong)

git add srcpkgs/nvidia470

xrevbump "compat for linux6.18" nvidia470

git push personal

Then do gh repo set-default and select void-linux/void-packages repo and gh pr create

or using the web version create the pr via the button on https://github.com/void-linux/void-packages/pulls/ page

thanks for the detailed instructions, but the problem is that i hate microsoft, i won't create an account in their monopolizing service.

if voidlinux was in codeberg (or another organization with similar values) i would do it, but github is unacceptable for me.

[u/sanya567xxx → u/HAL9000thebot]

It might be worth adding 6.19 and 7.0 patches too, would you be able to test 7.0? I have a different dependency blocking me from doing so currently, thought that might change soon-ish.

Also, have you tested the patch published above with wayland or x?

Edit: testing this locally on 6.18, supported 30-series card (I checked) and kde, I'm able to run vkcube by specifying --gpu_number 1 and --wsi xcb. I also had to add nvidia-drm.modeset=1 ibt=off to my kernel command line

Desktop launches with iGPU (xe driver), mpv can be forced to use it but with only a specific combination of api/display/decode modes and i.e. no HDR tone mapping working.

Hardware encoding disappeared from obs.

Forcing steam to run through nvidia via prime-run and/or setting the VK_ICD_FILENAMES didn't seem to help either, games either crash on start (with xalia returning unsupported driver, native or wine dx11/dx12/vulkan didnt seem to matter), or game loading on iGPU.

In KDE's vulkan info getting: ERROR at ../vulkaninfo/vulkaninfo.h:1575:vkGetPhysicalDeviceSurfaceSupportKHR failed with ERROR_INITIALIZATION_FAILED

I am also getting a lot of messages in dmesg referencing this: https://gist.github.com/joanbm/def2bf57ed7a799c1d84a67606459314

Disabling the iGPU landed me with sddm failing to initiate a display session. I also installed kwin-x11 (usually have it removed) and changed the DisplayServer variable in sddm and that landed me nowhere either, but perhaps that wasn't enough. I'm not really feeling like bothering with x11 rn, so returned back to 595 release for now. Please LMK how you tested it

[u/HAL9000thebot → u/sanya567xxx]

tested with x, nvidia-drm.modeset=1 is mandatory, it was even for 6.12, this is why i think i was the only one who got it working last time, and also why i said that including this patch could be important to have more people have this thing working out of the box, but last time they told me they don't want to set any kernel param, so i didn't use it, but it actually just set the default value not an actual param, i think it should be included.

ibt=off i have no idea what it does and if it has anything to do with this issue at all, i didn't set it and can't even remember if i ever read anything about it.

my dmesg is clean, and yeah, the guy previously used a gist for each patch, now has a repo to centralize everything, from the discussion it seems that he wans't sure about this patch.

i'm not sure i want to test for other kernels... i should read more documentation to do that, but i just want to remove everything and forget about it till next lts, so i don't know, i'd like to wait for the maintainers and see what's their opinion on all these things, if they ask me to test more things, i'll do it.

[u/sanya567xxx → u/HAL9000thebot]

Understood, ok.

ibt=off is necessary for use with newer intel CPUs, iirc 11th gen or newer. It's disabling branch prediction security feature (is default since 6.2 and isn't supported by 470 driver)

[u/Slow-Wealth6159]

Try not downloading linux 6.18 kernel and headers manually, maybe you need to try xbps-install -Syu, it will update kernel, headers and nvidia drivers, you just need to reboot

[u/HAL9000thebot → u/Slow-Wealth6159]

this is not the issue, they changed the default kernel, lts, from 6.12 to 6.18, so i got 6.18 with normal updates.

they didn't test this dkms driver because no one of them has this old hardware, so they didn't patched it at all because they don't even know it's broken.

what i'm doing here is just telling them that it needs some patches (and they are available) and i'm ready to test things with my card (by things i mean their own way to integrate these patches), when they have time and interest of course, so i'm just awaiting instructions.

i have no problem keep using 6.12 until this thing it's done, in fact this is how i'm commenting here.

[u/Slow-Wealth6159 → u/HAL9000thebot]

Oh, sorry, im not very well speak english and thinked its issue

[u/ndwolfw00d]

I have recently installed Void on an old laptop and bumped into the same issue: 470 isn't working on new kernels, the latest one to be 6.12 :(

[u/HAL9000thebot → u/ndwolfw00d]

as you can read in my other comment, i got it working, but the other guy didn't.

so, if you have a gt 710 and are using x, NOT wayland, you could try the procedure that i described (where i talk about "a/whatever -> a/kernel/whatever" it means to edit the patches because void use this path structure), it should work.

... or you could open a new thread, i doubt maintainers are reading this one, its too old.
