2017-12-11rcutorture: Simplify functions.sh include pathSeongJae Park1-1/+1
Inclusions of 'functions.sh' from 'kvm-test-1-run.sh' and 'kvm-recheck*.sh' use its absolute path. Because the directory containing 'functions.sh' is already in PATH, the full path is unnecessary. This commit therefore simplifies the inclusions to use the short relative path. Signed-off-by: SeongJae Park <sj38.park@gmail.com> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
2017-12-11rcutorture/kvm-recheck-*: Improve result directory readability checkSeongJae Park1-1/+1
The kvm-recheck-(lock|rcu|rcuperf).sh scripts check whether the user-specified results directory exists. If not, it prints out error message that says the specified directory is unreadable. To make the message more precise, this commit adds a readability check.

2016-03-31rcutorture: Make scripts analyze rcuperf trace data, if presentPaul E. McKenney1-0/+8
The rcuperf event-trace data is more accurate than are the rcuperf printk()s because locking keeps things ordered. This commit therefore parses and analyzes this event-trace data if present, and falls back on the printk()s otherwise. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
2016-03-31rcutorture: Print measure of batching efficiencyPaul E. McKenney1-10/+16
This commit adds a line giving the number of grace periods, the number of batches, and the ratio. The larger the ratio, the greater the batching efficiency. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
