[gentoo-dev] [PATCH] profiles/targets/desktop: enable USE=vulkan by default

[Sam James]

Ionen pointed this out again today and it made me look back at it; there's
no reason to not have vulkan on by default for desktop profiles.

In particular, Steam expects it for plenty of games to work, but at this point,
it's becoming jarring for users to _not_ have it as it's considered a fundamental part
of the modern desktop.

That's a non-sequitur. No reason to not have it on doesn't imply that
there is a reason to have it on.

Also, shouldn't we avoid enabling local flags in profiles?

That's what USE dependencies are for.

I keep forgetting that this is still not global either, guess it'll
ideally need another step first.

For often-used USE, that doesn't mean that every users should have to
enable it manually when they try to emerge the package. It would
notably be annoying if, e.g. opengl wasn't default either (if opengl
can be a default, I don't see why vulkan can't be in 2023).

I see this as a sane desktop default much like having png, jpeg, etc..
enabled.

Steam, games, and similar applications also come from several sources
not necessarily managed by portage all while expecting typical GPU
features (and png/jpeg support!) to work without having to dig in
USE flags on a desktop profile more than necessary. It's a better
out-of-the-box user experience.

Vulkan dependencies are also fairly trivial, typically it's just about
pulling vulkan-loader, headers, and glslang plus having support on mesa
or nvidia-drivers (always enabled regardless for the latter).

I see vulkan 31 times in use.local.desc, with slightly different
descriptions. Most notable difference:

app-office/libreoffice:vulkan - Enable Vulkan usage via the skia library (clang recommended)

Should it be renamed to "skia" for libreoffice, because that's also the
name of the upstream flag? libreoffice will also output a warning with
USE="vulkan -clang".

Right, this is a valid reason for enabling it.

IMHO this isn't. It is at least debatable if unpackaged proprietary
software should have any influence on our default settings.

That would not be accurate. The (bundled) skia is always being built, it is 
just the component using vulkan. That detail does not need to be part of the 
description though, so a global would fit.

Why is it "$(use_enable vulkan skia)" in econf arguments then?

configure --help says:

  --disable-skia          Disable building Skia. Use --enable-skia=debug to
                          build without optimizations.

Agreed, vulkan is absolutely needed on a modern desktop.

Its not supported in nouveau yet.

Older cards won't support it either (e.g. my 560ti doesn't), that's
not really a problem as far as enabling it and being usable for most
people goes. At most it's just a few not-useful dependencies by default
like having libwayland when you use Xorg.
