In gitlab #1097 the author comments that: https://gitlab.com/qemu-project/qemu/-/issues/1097#note_1044810483 "there are several distributions still available on 32-bit powerpc, e.g. Adélie Linux, for now still Void Linux, afaik Debian and OpenSUSE also still build packages" I checked these claims. Latest version OpenSuse LEAP doesn't support ppc32 bits: https://get.opensuse.org/leap/15.4/#download The last Debian that supports ppc32 was Debian 8: https://www.debian.org/ports/powerpc/#powerpc "Debian on 32-bit PowerPC (powerpc) It first became an official release architecture with Debian GNU/Linux 2.2 (potato) and had retained that status until the publication of Debian 9 (stretch). The last supported release for 32-bit PowerPC is Debian 8 (jessie)" And Void Linux doesn't seem to support any PowerPC flavor: https://voidlinux.org/download/ Adélie Linux supports ppc32. I can also add that FreeBSD also supports ppc32. Checking about/build-platforms.rst I can see that we would only somewhat care for FreeBSD here, since Debian 8 is already out of our support window. All that said, I don't have strong feelings against re-enabling it, specially because this build issue was deliberated caused by us. However, after re-enabling it, I would only care about build bugs that are reproduced on ppc32 FreeBSD.

I was able to install a debian sid chroot with this today[2]. which should be good enough to continue compile-testing. And Mark has hardware for actual testing. Given that almost all of the code overlaps with ppc64, I'm ok keeping it now. r~ [1] http://ftp.de.debian.org/debian-ports/pool-powerpc/ [2] https://github.com/vivier/linux-user-test-scrips.git
