BMC/Intel-BMC/linux.git/tools/virtio/ringtest, branch dev-4.7

tools/virtio: add noring tool

2016-06-06T10:00:11+00:00

Useful to measure testing framework overhead. Signed-off-by: Michael S. Tsirkin

tools/virtio/ringtest: fix run-on-all.sh to work without /dev/cpu

2016-06-06T10:00:11+00:00

/dev/cpu is only available on x86 with certain modules (e.g. msr) enabled. Using lscpu to get processors count is more portable. Signed-off-by: Mike Rapoport Signed-off-by: Michael S. Tsirkin

tools/virtio/ringtest: add usage example to README

2016-06-06T10:00:11+00:00

Having typical usage example in the README file is more convinient than in the git history... Signed-off-by: Mike Rapoport Signed-off-by: Michael S. Tsirkin

ringtest: pass buf != NULL

2016-05-22T16:44:14+00:00

just a stub pointer for now. Signed-off-by: Michael S. Tsirkin

virtio: add inorder option

2016-05-22T16:44:12+00:00

skips ring accesses but drops out of order support Signed-off-by: Michael S. Tsirkin

tools/virtio: add ringtest utilities

2016-01-26T08:18:30+00:00

This adds micro-benchmarks useful for tuning virtio ring layouts. Three layouts are currently implemented: - virtio 0.9 compatible one - an experimental extension bypassing the ring index, polling ring itself instead - an experimental extension bypassing avail and used ring completely Typical use: sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring It doesn't depend on the kernel directly, but it's handy to have as much virtio stuff as possible in one tree.
