 Posted: Sat Nov 05, 2022 5:09 pm Post subject: media-libs/mesa with NVK . possible? (solved) |
 |
|
hi all .
i have been following NVK development and wonder if it is possible to have media-libs/mesa with NVK. media-libs/mesa is quite a heavy ebuild
to modify . i am maintaining : https://github.com/hedmo/grate-overlay/tree/master/media-libs/mesa and can modify a bit but want to hear from the pros
how to add NVK in the ebuild " you know better then me  " . i have Turing and Kepler so it would be fun to continue the following on the hardware to .
regards

First problem is that NVK's code lives in a different Git repository (branch nvk/main of https://gitlab.freedesktop.org/nouveau/mesa), but these ebuilds pull from the grate-driver repository at GitHub. I suppose that you would have to create a new package (e.g. media-libs/mesa-nvk) that conflicts with media-libs/mesa (by writing a blocker).

Thank you for your reply .
About grate .It pulls from git and using a new driver "grate" with nouveau . I think it will be the same for NVK like i have done on mesa "grate" by adding flags for NVK to work with nouveau ? . But a more clean way would be to add a use flag for NVK as it is a feature for nouveau
and not a new driver?

The problem is that there are two different forks of Mesa here: the one that contains the code of the grate driver, and the one that contains the code of NVK. You can only install one fork. Hence, the need for two different packages that conflict with each other.

I know . I am going to use : media-libs/mesa::gentoo and modify the correct fork . My question is not about the fork but how to add NVK
support in ebuild . Should i add it as a useflag or add it as a driver. Add the driver like i have in my mesa "grate" or something else ?.
I can have as many media-libs/mesa as i like .... i only need to add the provider i dont want to use to package.mask . or create a ebuild
for that to : https://github.com/hedmo/grate-overlay/blob/master/sys-config/grate/files/package.mask/grate

To get the code of NVK, you have to fetch it from the nvk/main branch of the Nouveau GitLab repository. That means changing EGIT_REPO_URI. I am not in front of my Gentoo computer right now to test ebuild code, but I'd make the combination of VIDEO_CARDS="nouveau" and the vulkan USE flag enable NVK. As far as I can tell, NVK is enabled by adding "nouveau-experimental" to Meson's vulkan-drivers option.
But changing EGIT_REPO_URI, in turn, makes you lose the code of the grate-driver repository.

Which "other fork"? Is there any other that provides libvulkan_nouveau.so?

Yes and no . At first i used Karols (contributor) fork but ended up with : https://gitlab.freedesktop.org/nouveau/mesa.git .
And just patched it with the needs for kepler support. how about you . have you tested it out ?. i did test it out and have to say it was working quite well with NV166 but as i said
, broken with NVE0 .. |

No, I don't have the required hardware. But I thought I could help with the ebuild modifications
I did check that all ebuild phases up to and including src_install() succeeded with the changes, though.

Sorry for the necroposting, but I believe this is the most appropriate thread to discuss this topic.
I'm trying to get my RTX 2060 working with NVK, but haven't been successful so far. Sway segfaults with the default renderer and complains of missing layers when I use WLR_RENDERER=vulkan.
I'm on gentoo-sources-6.2 btw. I tried adding those modifications to my local mesa-9999.ebuild, which also pulls from that nouveau repository.
Should I remove the nouveau flag from the global userland? |

hi .
i am using a modified mesa-9999 for nvk on my rtx2060 and kepler systems. i cannot say much about your problem more then
that vulkan are missing a lot . one thing you need to know when you are using nouveau with tuning is that it does use nouveau driver.
nv166 is not supported yet and you only have kms with it. for me when i am checking vulkan with my tuning card i have only manage to see
one game that may want to use it and the rest are grabbing my IGPU . the only thing i can say is that you find what is needed ,
watch the nvk repo till it has been merged or fix it your self and contribute with it.

Well, I believe that I will need to wait a bit longer for them to have proper support, then. I don't have a fallback iGPU. 
Ty very much for letting me know. Cheers! |

NAK has been pushed to mesa and it depends on rustc . now mesa will fail with :
| Code: |

and i need some help sort it out .

| Is rustc actually installed and otherwise functional? We need to understand whether your problem is that you lack Rust intentionally and will not install Rust (in which case you probably need to revert the patches that depend on rustc), that you lack Rust currently but can install it (in which case you need to install it), or that you have Rust and the test program fails to accept it. |

Quick and dirty: | Code: | | rustc <(echo "fn main() { println!(\"Test\"); }"); echo $? |
If you get 0 (return code of rustc), then the code compiled successfully. Otherwise you get probably an error message and not 0 for the status code. |

| Rust is trying to link a 32-bit program, but is only finding 64-bit Rust libraries. This seems like a bug, but I cannot tell where. Do you need 32-bit support here? Disabling it might bypass the error until the problem is fixed upstream. |

Hu.
You are correct. It wont find 32bits rust libraries but i have it installed. After disabled multilib i got an other issue. Now i am missing syn package . Syn is not in portage but find it in rust overlay "dev-rust/syn". It is old and i dont think it is the right way to use that . |

ATM . i am trying to set up the dependencies . NAK depends on four crates: syn, proc-macro2, quote, and unicode-ident. this needs to be
prepared in the ebuild to . ATM i have manage to setup the download for some of them and moved the directory for syn to the right place :
| Code: |
NAK_URI="
https://github.com/dtolnay/syn/archive/refs/tags/2.0.15.tar.gz
https://github.com/dtolnay/proc-macro2/archive/refs/tags/1.0.56.tar.gz
https://github.com/dtolnay/quote/archive/refs/tags/1.0.25.tar.gz
"
if [[ ${PV} == 9999 ]]; then
EGIT_REPO_URI="https://gitlab.freedesktop.org/mesa/mesa.git"
inherit git-r3
else
SRC_URI="
${NAK_URI}
https://gitlab.freedesktop.org/mesa/mesa/-/archive/b7517aec9ee665c7b4c8c4629deeb0e34925b777/mesa-b7517aec9ee665c7b4c8c4629deeb0e34925b777.tar.gz
"
src_prepare() {
if [[ ${PV} != *9999* ]]; then
mv "${WORKDIR}"/syn-2.0.15 "${S}"/subprojects/syn-2.0.15 || die
fi
default_src_prepare
}
|
but now it fails with : "Subproject exists but has no meson.build file."
but i will get there |

ATM i have manage to compile it on 64bit because it fails on 32bit . now back to square one and figure out why it wont take 32bit.
here is the ebuild ATM: https://bpa.st/O45Q |

For now i have decided to drop mesa-24.x and continue with 23.x. now on to gsp . ATM i am getting a black screen when booting the kernel with :
| Code: |
nouveau.config=NvGspRm=1
|
I am at :6.7.0-rc7 and have the firmware blobs :
| Code: |
booter_load-535.113.01.bin booter_unload-535.113.01.bin bootloader-535.113.01.bin gsp-535.113.01.bin
|
.now i have not fully understand what to do next but i have tried to add :
| Code: |
cat /etc/dracut.conf.d/firmware.conf
install_items+=" /usr/src/open-gpu-kernel-modules/_out/nvidia/tu116/gsp/booter_load-53514602.bin /usr/src/open-gpu-kernel-modules/_out/nvidia/tu116/gsp/booter_unload-53514602.bin /lib/firmware/nvidia/tu102/gsp/gsp-535.113.01.bin "
|
but still a black screen at boot. |
