#58868 — Bug#874536: linux: arm64ilp32 support

[Multipart message — attachments visible in raw view] — view raw

Source: linux
Version: 4.9.30-2+deb9u2.1
Severity: wishlist
Tags: patch

Attached are the packaging changes needed to make the kernel build for arm64ilp32.

The arm64ilp32 (aarch64-linux-gnu_ilp32) kernel support is not yet
merged upstream, so I guess you are not going to include this until it
is, but as I've done the work, it's useful to file this patch so you
have the necessary info to hand when the time comes.

I also have a corresponding patch for the kernel support, but it's
large, so I'll just point to it here, for anyone that wants to build this in debian: 
https://anonscm.debian.org/cgit/users/wookey/rebootstrap.git/commit/?h=ilp32-stable&id=01fe063bff353cba63b2048ff803f41314b888a5

Status for the port (in Debian) is tracked here: https://wiki.debian.org/Arm64ilp32Port

Similar to x32, this Debian architecture should *not* have its own
redundant kernel image package.

Time is nature's way of making sure that everything doesn't happen at
once.

OK, but we need the kernel-headers package in order build the
toolchain, so at least that needs to be built (which is in fact all I
have done/tested so far).

I agree that the arm64 kernel will work for both. But will
dependencies work for automatically bringing that in?

Yes, and that's trivial to add once dpkg recognises the architecture
(remember that you have to get it added in stable, since dak uses the
stable version to validate the architecture list in an upload).

The only dependencies on kernel image packages are (or should be) from
the corresponding metapackages.  Once those are installed, upgrades
should work automatically.  However, d-i and vmdb will need to be
changed to add the foreign architecture and install a foreign kernel
metapackage.

Fortunately that was done, so stable dpkg recognises arm64ilp32

Right. Makes sense. Thanks.
