[bug#62309] [PATCH core-updates 0/2] Fix qemu build

[Josselin Poiret via Guix-patches via]

Hi,

Quick patches to fix some dependencies of QEMU that didn't build on my side!

Best,

Josselin Poiret (2):
  opensbi: Build with default gcc, with microarch rv64g
  u-boot: Fix build under Python 3.10.

Nitpick: The change log should state the change; it took me an instant
to realize the "Do it" meant implement the git summary description.  The
summary can be more brief (or it could say the same if it fits under 80
chars).

I don't quite understand, but then I don't know what is opensbi either,
so I'd have to read more.  Or if you can expound a bit that comment for
neophytes like me, that'd be nice.

Thanks for the fix!

[Josselin Poiret via Guix-patches via]

Hi Maxim,

Thanks for the review!  Here's an updated patchset with the requested changes.
To be honest, I don't think anyone would care about gnu/local.mk alignment, but
that's a discussion for another time.

By the way, I don't really know what opensbi is for either :)

Best,

FIXME and other similar comment prefixes are more conventionally used
with a colon (FIXME: ...), I think.  I also prefer to keep the patch
origin tracking in the patch itself (and 'guix lint' checks for that
nowadays, at least in some cases).  The patch should fail to apply when
after it's included in a release.

Feel free to push with these suggested changes.

Right, I added this FIXME in the heat of the moment.  I don't really
mind either way, although I find it nice that when it fails to apply,
anyone can see this comment and conclude that it should be ok to remove
(as opposed to some patches failing because they're not up to date).
What do you mean by "patch origin tracking", and it being taken care of
by `guix lint`?

> Feel free to push with these suggested changes.

I don't know if this was directed at me or committers, but I'll just add
that I do not have commit rights, if anyone else wants to have a look
and push :)

+Python 3.10 requires defining PY_SSIZE_T_CLEAN. This will be fixed in
+swig 4.10 but it is not clear when it will be released. There was a
+warning since python 3.8.
