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:
