[gentoo-dev] [RFC] arm64 stable profiles

Hello,

I intend to mark the following profiles stable within a week or so:

default/linux/arm64/17.0
default/linux/arm64/17.0/systemd

arm64 (AArch64) is becoming a rather major architecture in the computer
industry, from small single board computers to very beefy servers. It
is about time to grace it with stable Gentoo support.

Thanks to access to a 96 cores @ 2.0GHz arm64 server with 128GB RAM it
has been easy to finish up fixing our keywording issues and clear up
stabilization queue. This access has been kindly provided to Gentoo by
packet.net via the Works on Arm initiative.


Before proceeding I intend to get the following still done first:

* Clear up the stabilization queue (only about 3 actionable bugs still
to do at the moment, rest is caught up)
* Reduce things that are USE masked (from early keyword issue solving),
before higher care needs to be taken for that work with stable
profiles; in particular I want to concentrate on test dependencies and
some more widely used optional features and their external deps

Shortly afterwards:
* Spin a new stage3
* Look into moving the stages out of experimental status

Later plans:
* Support more server software
* Introduce ~arm64 GNOME3 support (and stabilize later on); (thanks Ben
Kohler, for donating me a DragonBoard 410c a while back, on which I'll
be able to test running it)
* Start actively taking and handling keywording and stable requests of
things people want to use on their Aarch64 hardware
* More automated stage tarballs
* Become Gentoo Security supported
* Overtake amd64 in supported maintained software?


The intention is also to follow up with the following profiles soon
enough, as we start tracking more desktops as well:
default/linux/arm64/17.0/desktop
default/linux/arm64/17.0/desktop/system
d
default/linux/arm64/17.0/developer

Still pondering about the default/linux/arm64/17.0/developer profile,
given its effect on repoman speed for all, compared to its value to
end-users and inflexibility to developers for whom this is meant for.

Once GNOME is supported, we'd also make new
default/linux/arm64/17.0/desktop/{,systemd} profiles into stable and
whatever other profiles that have their relevant packages properly
supported in the future (e.g. plasma).


Bikeshed now or forever hold your peace.
