2013-03-15perf tests: Make attr script verbose friendlyJiri Olsa
Making the attr test script runner to pass proper verbose option. Also making single '-v' be more reader friendly and display just the test name. Making the current output to be display for '-vv'.

2013-01-30perf tools, powerpc: Fix compile warnings in tests/attr.cSukadev Bhattiprolu
We print several '__u64' quantities using '%llu'. On powerpc, we by default include '<asm-generic/int-l64.h> which results in __u64 being an unsigned long. This causes compile warnings which are treated as errors due to '-Werror'. By defining __SANE_USERSPACE_TYPES__ we include <asm-generic/int-ll64.h> and define __u64 as unsigned long long. Changelog[v2]: [Michael Ellerman] Use __SANE_USERSPACE_TYPES__ and avoid PRIu64 format specifier - which as Jiri Olsa pointed out, breaks on x86-64.

2013-01-24perf tests: Check python path on attr and binding testNamhyung Kim
Current perf test code tries to execute python version 2 in order to test attributes on perf_event_open syscall. However it's not default python version anymore a system can have python v3 only or v2 with a different name (e.g. python2). So if there's no such python interpreter with the name 'python', the test would fail like this (yes, it's happened on my new archlinux laptop :). 13: struct perf_event_attr setup :sh: python: command not found FAILED! As we can pass name of the python interpreter on make, use it for the attr test also.

2013-01-24perf python: Fix breakage introduced by the test_attr infrastructureArnaldo Carvalho de Melo
The test_attr infrastructure hooks on the sys_perf_event_open call, checking if a variable is set and if so calling a function to intercept calls and do the checking. But both the variable and the function aren't on objects that are linked on the python binding, breaking it: # perf test -v 15 15: Try 'use perf' in python, checking link problems : --- start --- Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: /home/acme/git/build/perf//python/perf.so: undefined symbol: test_attr__enabled ---- end ---- Try 'use perf' in python, checking link problems: FAILED! # Fix it by moving the variable to one of the linked object files and providing a stub for the function in the python.o object, that is only linked in the python binding. Now 'perf test' is happy again: # perf test 15 15: Try 'use perf' in python, checking link problems : Ok # Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-0rsca2kn44b38rgdpr3tz6n5@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2012-11-05perf tests: Removing 'optional' fieldJiri Olsa

2012-10-31perf tests: Add framework for automated perf_event_attr testsJiri Olsa
The idea is run perf session with kidnapping sys_perf_event_open function. For each sys_perf_event_open call we store the perf_event_attr data to the file to be checked later against what we expect.
