2020-08-24	rcuperf: Change rcuperf to rcuscale	Paul E. McKenney	1	-109/+0
	This commit further avoids conflation of rcuperf with the kernel's perf feature by renaming kernel/rcu/rcuperf.c to kernel/rcu/rcuscale.c, and also by similarly renaming the functions and variables inside this file. This has the side effect of changing the names of the kernel boot parameters, so kernel-parameters.txt and ver_functions.sh are also updated. The rcutorture --torture type was also updated from rcuperf to rcuscale. [ paulmck: Fix bugs located by Stephen Rothwell. ] Reported-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Paul E.

2019-03-26	tools/.../rcutorture: Convert to SPDX license identifier	Paul E. McKenney	1	-15/+2
	Replace the license boiler plate with a SPDX license identifier. While in the area, update an email address and add copyright notices. Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com>
2018-02-20	torture: Grace periods do not piggyback off of themselves	Paul E. McKenney	1	-1/+2
	The rcuperf trace-event processing counted every "done" trace event as a piggyback, which is incorrect because the task that started the grace period didn't piggyback at all. This commit fixes this problem by recording the task that started a given grace period and ignoring that task's "done" record for that grace period. Signed-off-by: Paul E.

2018-02-20	torture: Adjust rcuperf trace processing to allow for workqueues	Paul E. McKenney	1	-4/+4
	The rcuperf event-trace processing assumes that expedited grace periods start and end on the same task, an assumption that was violated by moving expedited grace-period processing to workqueues. This commit removes this now-fallacious assumption from rcuperf's event-trace processing. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
2017-12-11	rcutorture: Simplify functions.sh include path	SeongJae Park	1	-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>
2016-03-31	rcutorture: Make scripts analyze rcuperf trace data, if present	Paul E. McKenney	1	-0/+121
	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>
