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> 2013-03-20T03:30:42+00:00 Rusty Russell rusty@rustcorp.com.au 2013-03-18T02:52:19+00:00 urn:sha1:61d0b5a4b2777dcf5daef245e212b3c1fa8091ca This makes them a bit more like the kernel headers, so we can include more real kernel headers in our tests. In addition this means that we don't break tools/virtio with the next patch. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
