tools/virtio: add vring_test.
This is mainly to test the drivers/vhost/vringh.c code, but it also uses the drivers/virtio/virtio_ring.c code for the guest side. Usage for testing the basic implementation: ./vringh_test # Test with indirect descriptors ./vringh_test --indirect # Test with indirect descriptors and event indexex ./vringh_test --indirect --eventidx You can run a parallel stress test by adding --parallel to any of the above options. eg ./vringh_test --parallel: Using CPUS 0 and 3 Guest: notified 10107974, pinged 107970 Host: notified 108158, pinged 3172148 ./vringh_test --indirect --eventidx --parallel: Using CPUS 0 and 3 Guest: notified 156357, pinged 156251 Host: notified 156251, pinged 78179 Average of 50 times doing ./vringh_test --indirect --eventidx --parallel: 2.840000-3.040000(2.927292)user Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
