perf tools: Have the page size value available for all tools

2012-10-06T19:33:14Z

Its such a common need that we might as well have a global with that value.

perf test: Add test to check we correctly parse and match syscall open parms

2012-09-26T16:42:01Z

It will set up a syscall open tracepoint event, generate an open with invalid flags, then check those flags were the ones reported in the tracepoint fired. For the filename we need vfs:getname, but that will go thru some more iterations as the vfs getname codebase is going thru changes lately. When that is in I'll just check that the perf_evsel__newtp constructor is not bailing out and then add it to the evlist, catch the event and check the filename against the one used in the 'open' call used to trigger the event.

perf evsel: Know if byte swap is needed

2012-09-26T15:48:18Z

Instead of passing it around for parsing as an explicit parameter, will help with reading tracepoint fields when not using a perf session or pevent structure, i.e. for non perf.data centered workflows.

perf test: Fix build failure

The commit 6a6cd11d4e57 ("perf test: Add test for the sched tracepoint format fields") added following build error: CC builtin-test.o builtin-test.c: In function ‘perf_evsel__test_field’: builtin-test.c:1216:6: error: variable ‘ret’ set but not used [-Werror=unused-but-set-variable] builtin-test.c: In function ‘perf_evsel__tp_sched_test’: builtin-test.c:1242:6: error: variable ‘ret’ set but not used [-Werror=unused-but-set-variable] cc1: all warnings being treated as errors make: *** [builtin-test.o] Error 1 Signed-off-by: Namhyung Kim Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1348539628-3821-1-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf test: Add test for the sched tracepoint format fields

2012-09-24T15:29:19Z

So that we make sure the routines that do event format parsing are working on at least two well know scheduler tracepoints.

perf test: Fixup for the die() removal

2012-09-14T18:48:27Z

The commit 32c7f7383a09 ("perf test: Remove die() calls") replaced die() call to pr_debug + return -1, but it should be pr_err otherwise it'll not show up unless -v option is given. Fix it.

perf tools: Use __maybe_used for unused variables

2012-09-11T15:19:15Z

perf defines both __used and __unused variables to use for marking unused variables. The variable __used is defined to __attribute__((__unused__)), which contradicts the kernel definition to __attribute__((__used__)) for new gcc versions. On Android, __used is also defined in system headers and this leads to warnings like: warning: '__used__' attribute ignored __unused is not defined in the kernel and is not a standard definition. If __unused is included everywhere instead of __used, this leads to conflicts with glibc headers, since glibc has a variables with this name in its headers. The best approach is to use __maybe_unused, the definition used in the kernel for __attribute__((unused)). In this way there is only one definition in perf sources (instead of 2 definitions that point to the same thing: __used and __unused) and it works on both Linux and Android. This patch simply replaces all instances of __used and __unused with __maybe_unused.

perf test: Remove die() calls

2012-09-09T14:39:02Z

Just use pr_err() + return -1 and let the other tests run as well and then the perf's main() exit doing whatever it needs.
