Subject: [Qemu-devel] [PATCH v2] configure: Warn about deprecated hosts
Date: Tue, 21 Mar 2017 14:31:57 +0000 [thread overview]
Message-ID: <1490106717-9542-1-git-send-email-peter.maydell@linaro.org> (raw)
We plan to drop support in a future QEMU release for host OSes
and host architectures for which we have no test machine where
we can build and run tests. For the 2.9 release, make configure
print a warning if it is run on such a host, so that the user
has some warning of the plans and can volunteer to help us
maintain the port if they need it to continue to function.
This commit flags up as deprecated the CPU architectures:
* ia64
* sparc
* anything which we don't have a TCG port for
(and which was presumably using TCI)
and the OSes:
* GNU/kFreeBSD
* DragonFly BSD
* NetBSD
* OpenBSD
* Solaris
* AIX
* Haiku
It also makes entirely unrecognized host OS strings be
rejected rather than treated as if they were Linux (which
likely never worked).

v2: mark FreeBSD as 'supported' as I have got a
VM config going for it for build tests.
NetBSD doesn't boot inside KVM (!), and OpenBSD I have got
running but "make check" hangs where we try to run guest code.
