libxenevtchn will provide a stable API and ABI for accessing the evtchn device. The functions are moved into the xenevtchn namespace to make a clean break from libxc and avoid ambiguity regarding which interfaces are stable. All in-tree users are updated to use the new names. Upon request (via #define XC_WANT_COMPAT_EVTCHN_API) libxenctrl will provide a compat API for the old names. This is used by qemu-xen for the time being. qemu-xen-traditional is updated in lockstep. This leaves a few event channel related functions which go via privcmd (EVTCHNOP) rather than ioctls on the /dev/xen/evtchn device in libxenctrl. Specifically: - xc_evtchn_alloc_unbound - xc_evtchn_reset - xc_evtchn_status Note that xc_evtchn_alloc_unbound's functionality is also provided by xenevtchn_bind_unbound_port() (née xc_evtchn_bind_unbound_port) and is probably redundant. These functions do not appear to be needed by qemu-dm, qemu-pv (provision of device model to HVM guests and PV backends respectively) or by libvchan suggesting they are not needed by non-toolstack uses of event channels. QEMU does use these in hw/xenpv/xen_domainbuild.c but that is a "toolstack use". The new library uses a version script to ensure that only expected symbols are exported and to version them such that ABI guarantees can be kept in the future.
