[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH QEMU-XEN-TRADITIONAL v3 2/5] qemu-xen-traditional: Use libxenevtchn
/dev/xen/evtchn related wrappers have been moved out of libxenctrl
into their own library.
Note that i386-dm/helper2.c's xc_interface * was always really an
xc_evtchn *, it's just they used to be typedefs to the same thing...
