[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH] stubdom: make the build more generic
stubdom: make the build more generic by moving as many stubdom parts
into stubdom/ as possible. That also permits to build all of
ioemu, c and caml stubdoms at the same time.
