This appendix outlines which platforms are the major build +targets. These platforms are used as the basis for deciding upon the +minimum required versions of 3rd party software QEMU depends on. The +supported platforms are the targets for automated testing performed by +the project when patches are submitted for review, and tested before and +after merge. + +If a platform is not listed here, it does not imply that QEMU won't +work. If an unlisted platform has comparable software versions to a +listed platform, there is every expectation that it will work. Bug +reports are welcome for problems encountered on unlisted platforms +unless they are clearly older vintage than what is described here. + +Note that when considering software versions shipped in distros as +support targets, QEMU considers only the version number, and assumes the +features in that distro match the upstream release with the same +version. In other words, if a distro backports extra features to the +software in their distro, QEMU upstream code will not add explicit +support for those backports, unless the feature is auto-detectable in a +manner that works for the upstream releases too. + +The `Repology`_ site is a useful resource to identify +currently shipped versions of software in various operating systems, +though it does not cover all distros listed below. + +Linux OS, macOS, FreeBSD, NetBSD, OpenBSD +----------------------------------------- + +The project aims to support the most recent major version at all times. Support +for the previous major version will be dropped 2 years after the new major +version is released or when the vendor itself drops support, whichever comes +first. In this context, third-party efforts to extend the lifetime of a distro +are not considered, even when they are endorsed by the vendor (eg. Debian LTS). + +For the purposes of identifying supported software versions available on Linux, +the project will look at CentOS, Debian, Fedora, openSUSE, RHEL, SLES and +Ubuntu LTS. Other distros will be assumed to ship similar software versions. + +For FreeBSD and OpenBSD, decisions will be made based on the contents of the +respective ports repository, while NetBSD will use the pkgsrc repository. + +For macOS, `HomeBrew`_ will be used, although `MacPorts`_ is expected to carry +similar versions. + +Windows +------- + +The project supports building with current versions of the MinGW toolchain, +hosted on Linux (Debian/Fedora). + +The version of the Windows API that's currently targeted is Vista / Server +2008. + +.. _HomeBrew: https://brew.sh/ +.. _MacPorts: https://www.macports.org/ +.. _Repology: https://repology.org/ |
