From 1515c5ce26ae45a8ecea4e68a484562ca4356442 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 20 Mar 2013 13:50:24 +1030 Subject: 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 --- tools/virtio/linux/uio.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'tools/virtio/linux') diff --git a/tools/virtio/linux/uio.h b/tools/virtio/linux/uio.h index ecbdf922b0f4..cd20f0ba3081 100644 --- a/tools/virtio/linux/uio.h +++ b/tools/virtio/linux/uio.h @@ -1 +1,3 @@ +#include + #include "../../../include/linux/uio.h" -- cgit v1.2.3
