[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-ia64-devel] RFC: adding a dom0_firmware_setup hypercall
Hi,
this a just for review and comments. The purpose is not to use
DOM0_SETVPUCONTEXT to initialiaze a domain.
This is the first step for save&restore.
[This patch also contains warning cleanup, it will be separated of course].
Tristan.
