H A D | pvcalls-front.h | 45ddce21 Mon Oct 30 17:40:59 CDT 2017 Stefano Stabellini <sstabellini@kernel.org> xen/pvcalls: implement sendmsg
Send data to an active socket by copying data to the "out" ring. Take the active socket out_mutex so that only one function can access the ring at any given time.
If not enough room is available on the ring, rather than returning immediately or sleep-waiting, spin for up to 5000 cycles. This small optimization turns out to improve performance significantly.
