[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH, RFC] qemu: build adjustments
QEMU by itself can be built outside of its source directory. With the
qemu repository being separate from the hypervisor/tools one it seems
to make sense to make use of this feature, but doing so requires a
couple of adjustments to the Xen changes to it. Basically, if
CONFIG_QEMU is found to indicate an existing directory, this directory
will be used rather than cloning the git repo into the build tree.
The patch contains QEMU and tools/stubdom changes together for the
moment (with QEMU supposed to be residing in qemu/). For applying
this would need to be split.
