We're struggling quite badly with our CI minutes on the shared gitlab runners, so we urgently need to think of ways to cut down our supported build and target environments. Hardly anybody uses QEMU system emulation on 32-bit x86 and arm hosts anymore, so it's time to deprecate these environments now.
This is a follow-up patch series from the previous discussion here: https://lore.kernel.org/qemu-devel/20230130114428.1297295-1-th...@redhat.com/ where people still mentioned that there is still interest in certain support for 32-bit host hardware. But as far as I could see, there is no real need for system emulation on 32-bit x86 host and 32-bit arm hosts anymore, so it should be fine if we drop these host environments soon (these are also the two architectures that contribute the most to the long test times in our CI, so we would benefit a lot by dropping those). v4: - Drop the patch that deprecated qemu-system-arm since it still might be required to enforce 32-bit guests with TCG - Only deprecate system emulation on 32-bit x86 hosts since user-mode emulation might still be useful in certain scenarios - Add a sentence how to enforce 32-bit mode with qemu-system-x86_64 v3: - Update some commit descriptions according to the suggestions in v2 - Added the Reviewed-bys from v2 v2: - Split binary and host deprecation into separate patches - Added patches to immediately drop the jobs from the CI Thomas Huth (5): docs/about/deprecated: Deprecate 32-bit x86 hosts for system emulation docs/about/deprecated: Deprecate the qemu-system-i386 binary gitlab-ci.d/crossbuilds: Drop the i386 system emulation job docs/about/deprecated: Deprecate 32-bit arm hosts for system emulation gitlab-ci.d/crossbuilds: Drop the 32-bit arm system emulation jobs docs/about/deprecated.rst | 34 ++++++++++++++++++++++++++++++++++ .gitlab-ci.d/crossbuilds.yml | 24 ------------------------ 2 files changed, 34 insertions(+), 24 deletions(-) -- 2.31.1
