perf: Fix parsing of __print_flags() in TP_printk()

2012-01-12T19:29:27Z

commit 49908a1b25d448d68fd26faca260e1850201575f upstream. A update is made to the sched:sched_switch event that adds some logic to the first parameter of the __print_flags() that shows the state of tasks. This change cause perf to fail parsing the flags. A simple fix is needed to have the parser be able to process ops within the argument. Reported-by: Andrew Vagin Signed-off-by: Steven Rostedt Signed-off-by: Greg Kroah-Hartman

perf stat: Failure with "Operation not supported"

2011-12-05T16:32:40Z

perf stat is failing on PowerPC: Error: open_counter returned with 95 (Operation not supported). /bin/dmesg may provide additional information. Fatal: Not all events could be opened. commit 370faf1dd046 (perf stat: Fail softly on unsupported events) added a check for failure returning ENOENT, but the POWER backend returns EOPNOTSUPP. It looks like alpha, blackfin and mips do the same. With the patch applied, things work as expected: Performance counter stats for '/bin/true': 0.362176 task-clock # 0.623 CPUs utilized 0 context-switches # 0.000 M/sec 0 CPU-migrations # 0.000 M/sec 28 page-faults # 0.077 M/sec 1,677,020 cycles # 4.630 GHz stalled-cycles-frontend stalled-cycles-backend 431,220 instructions # 0.26 insns per cycle 101,889 branches # 281.325 M/sec 4,145 branch-misses # 4.07% of all branches 0.000581361 seconds time elapsed Cc: # 3.0+ Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20111202093833.5fef7226@kryten Signed-off-by: Anton Blanchard Signed-off-by: Arnaldo Carvalho de Melo

ktest: Check parent options for iterated tests

2011-11-18T16:07:24Z

Let's say we have "OUTPUT_DIR = build/${TEST_NAME}", and we're iterating a test. In the second iteration of a test, the TEST_NAME of the test we're repeating is not used. Instead, ${TEST_NAME} appears literally: touch /home/rabin/kernel/test/build/${TEST_NAME}/.config ... SUCCESS Fix this by making __eval_option() check the parent test options for a repeated test.
