[bug#69637] [PATCH mesa-updates 0/6] gnu: mesa: Update to 24.0.2.

[aurtzy]

Hello!

This series of patches updates Mesa to the latest stable version with the NVK
Vulkan driver for NVIDIA GPUs enabled for x86_64 systems.

Mesa 24.0.2 depends on a newer version of libdrm (>= 2.4.119), which is
pending in another issue (https://issues.guix.gnu.org/68845).

Some packages (rust-syn-2.0.39, rust-proc-macro2-1.0.70, rust-quote-1.0.33)
were added specifically to be used as sources that satisfy explicit versions
of dependencies required by Mesa (for NVK).  Would it be better to inline
origins in the change-subproject-sources phase?  The same question also
applies for the rust-unicode-ident-1 source.

Currently, the Rust dependencies are found in the build by substituting the
fallback https://* URLs in the relevant ./subprojects/*.wrap files with
file://*, then relying on the fallback to "download" from the store.  It
seemed a bit hacky doing it this way, but I'm not aware of a better solution.

A newer Meson version is also required for NVK (>= 1.3.0), which this patch
series adds a new variable for.

x86_64-linux and i686-linux have been tested to successfully build.

Cheers,

aurtzy

Are there other architectures which have rust based drivers? x86_64
isn't the only architecture which has rust building on it.

The crates are also available in
%output/share/cargo/registry/name-version.crate, although I can't think
of a good way to address them by name without using find-files.

I would personally replace the versions requested by mesa with whatever
version we happen to have in guix so that we don't have to add special
versions just for mesa.

[Efraim Flashner]

[-- Attachment #1: Type: text/plain, Size: 496 bytes --]

I've applied rust-bindgen-cli to the master branch. I renamed it to
remove the version at the end and I switched to the crate-uri since
there's no tests in the bindgen-cli folder of the bindgen git repo.

I also moved it to the rust-apps module and added the shell completions.

There doesn't appear to be any official documentation stating 
architecture requirements for Mesa with NVK/Rust, however I have added 
few new inputs other than rust to get NVK working. I've only done 
extensive testing with x86_64 so I was unsure of potential issues with 
including this on other architectures (other than i686 not building rust).

I have/had tried a few approaches to use the crates already available in 
Guix with no success so far. I've outlined the approaches below; still 
looking into solutions, but perhaps there's something I'm missing or 
haven't tried yet?

- Simply including crates as (native-)inputs does not make them 
discoverable by meson.

- Mesa uses these *.wrap files which specify the rust dependency 
versions, source URLs, and tar hashes. I currently get the build working 
by relying on meson to fall back to "downloading" from a patched source 
URL (pointing to store), although it still has to match the hash.

- I recently discovered a way to disable the hash requirement so I could 
use a different input version (i.e. one from Guix), but doing it causes 
"File src/lib.rs does not exist" errors. I'm still looking into this 
right now, as it seems promising.

- Old IRC logs point to projects like newsboat and librsvg which also 
mix cargo with with another build system, but these start with 
cargo-build-system with phases added/replaced from the second build 
system. Cargo.toml doesn't exist in Mesa either (which 
cargo-build-system seems to depend on), so experimenting with using 
cargo-build-system didn't yield much.

I wanted to look more into the third bullet before responding, but I 
felt it would be unfortunate to have this information rot while trying 
to make time for hacking - hopefully it's still useful.

Cheers,

aurtzy

I guess this is the main question, if we will try to enable the NVK
driver for other architectures, if that is supported. We could also
leave it for the known working x86_64 to start. I would say we could
provide a mesa variant package for testing, but that might be
difficult as far as I know (e.g. trying to get Xorg to use a different
mesa package looked difficult from what I saw others try).

We could try just checking for where rust is available (is that just
supported-systems for the rust package, or do we have other logic?)
and building with NVK to see what fails... Though with how long it can
take us to build on other architectures, that might take a while to
find out and then correct.

Thanks for this additional info, aurtzy, and your work on this!

Efraim, any thoughts on the rust related stuff based on these other
attempts? I'm not familiar enough with rust, rust packaging, or what
mesa is doing in the meson builds to comment right now.

I would like to get the build farm cranking on the updates I have
queued for mesa-updates (cairo, libdrm, mesa, vulkan). We could also
do just the version update of mesa to start, or just NVK on x86_64,
leaving future changes for the next round. I don't have a preference
myself, other than wanting to get this branch moving with these
updates.

Thoughts?

And thanks both of you again!
John

We have (supported-package? package) to check if a package is supported.
Then we can wrap the phase in #$@(if (assoc-ref inputs "rust") ...) and
it should all just work.

I also tried a couple of different options. The one that I most want
involved using with-output-to-file to rewrite the wrap file and
replacing all the fields. I borrowed the file-sha256 function from
guix/build/cargo-utils.scm to get the source_hash.  In the end I wasn't
able to get the gexp and un-gexp bits working to actually get the file
written.

When I kept a failed build I saw that the 'directory' field is the
directory into which meson writes the meson.build file, which is why
using a different version of the rust crate caused problems with
src/lib.rs not existing.  I suppose we could start from your patch and
then, after running substitute, extract the tarball into either a
hardcoded path (determined after manually reading the sources) or we can
extract the 'directory' field by reading the sources and then untar the
source there.

Looking at qa.guix.gnu.org I believe that gnome-team is going to merge
soon, and then the emacs-team is up next.

I would prefer to use the already packaged crates but we can go ahead
and use the ones from the patchset for now and work out swapping them
later.  As far as which architectures, I think I'd start with x86_64
only first.  And sprinkle a couple of TODOs around.

[bug#69637] [PATCH mesa-updates v2 0/5] gnu: mesa: Update to 24.0.3.

[aurtzy]

New patchset coming in.  Mesa has been updated to 24.0.3, and I've added TODO
comments for future work as suggested.

NVK on 24.0.3 is also still considered experimental, so if that's a concern we
could save this work for 24.1 when it's planned to move out of this stage.

[bug#69637] [PATCH mesa-updates v2 0/5] gnu: mesa: Update to 24.0.3.

Right, I forgot about that. I also remember that it depends (or is
helped by) some changes in recent kernels, 6.7 and/or 6.8 if I remember.

So, maybe we can take this approach:

1. Make the update just to 24.0.3 for mesa (does that require newer
meson?)

2. Add any rust packages as needed to master

3. Either add a mesa-next (to master?) or followup on mesa-updates after
it gets merged to master with a mesa based on 24.1 (as soon as it is
tagged) with NVK enabled. This will let us at least get mesa built and
make for a headstart come 24.0.1.

With 24.1 soon ("this quarter"?) and how long it can take us to build on
non-x86 architectures, it would be nice to have that go quickly. Since
I'll be including cairo, libdrm, and vulkan updates (at least) this
round, I anticipate it taking a bit.

Does that sound okay? It'll give some time to test things and clean
up/find alternatives as Efraim suggested.

I'm also not opposed to just enabling NVK now. In that case, we should
have one commit to just update mesa and another to enable NVK.

Thanks both of you! I would like to start pushing patches and building
everything in the next few days, especially as some have sat for a while
and it will take time to build.

6.6 appears to be the minimum required according to mesa docs, if that 
changes anything: 
https://docs.mesa3d.org/drivers/nvk.html#kernel-requirements

The meson 1.3 requirement is only for NVK; mesa 24.0.3 without NVK can 
build with the current meson.

Looks like 24.1 stable should be releasing May-June: 
https://docs.mesa3d.org/release-calendar.html

This approach sounds fine to me. I don't mind holding back the 
NVK-related changes for more testing and improvement.

All the more reason to pre-empt it a bit, as I will be away for most
of May and the beginning of June :-)

Great, thanks!

I applied a version only bump locally (haven't pushed it out live yet)
and so far so good. I put you as co-author, even though it was just
the hash basically, you did save me having to do that.

Once this is on mesa-updates, you can base your patches on that (bunch
of other updates too) and it can live on that branch in prep for 24.1.

Thanks again!
John

mesa updated to 24.0.3 in b43d36a556c1c1d75fdffbec08d8c39121a528cd and
then 24.0.4 in 23928e2d426fb63945682c2c8c60145fe4d333dd.

Closing this issue number, but thank you for the efforts so far for NVK.
Happy to have patches for 24.1 on mesa-updates when you have them.

John
