If there's not OUTPUT variable defined the PYTHONPATH ends up with /python. We need to remove the extra '/'. Signed-off-by: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/n/tip-h1hzfyfcdxjnuq9fin2cjwlr@git.kernel.orgSigned-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

That consolidates the grouping of host + guests, isolating a bit more of functionality now centered on 'perf_session' that can be used independently in tools that don't need a 'perf_session' instance, but needs to have all the thread/map/symbol machinery.

It was being used just for its stats member, so ditch session->hists and use just what is needed, session->stats. This completes the move support multiple events in the hists layer, the last user of session->hists was 'perf diff' but Jiri Olsa has fixed that some time ago.

We were calling perf_session__process_machines(), that would first pass the struct machine associated with the host to the provided callback, perf_event__synthesize_guest_os() that would test if it was the host and if so wouldn't do anything. Ditch this contraption, just call directly machines__process with the list of guests.

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
🇸🇭 python: command not found FAILED! As we can pass name of the python interpreter on make, use it for the attr test also.

Adding event parsing test for '*:*' tracepoints. Checking the count matches all the tracepoints available plus current standard tracepoint perf_event_attr check. This test exposes warnings from traceevent lib about not being able to parse some tracepoints' format data. Exposing these messages in the automated test suite will probably speed up the fix ;-) Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1355749718-4355-4-git-send-email-jolsa@redhat.comSigned-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Adding support for wildcards '*?" in the tracepoint system part. It's now possible to open all available tracepoints like: # perf stat -e '*:*' ls You might need to increase limit for open files via ulimit. If ftrace events tracepoints are configured in, the record command fails on above event selection because of them. The stat command disables counters that fails to open, the record command fails completely. We probably want to be smarter here.

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.

As they are used from diff and event group report, add a test case to verify their behaviors. In this test I made a fake machine and two evsel. Each evsel got 10 samples (so hist entries) - 5 are common and the rests are not. So after hists__match() both of them will have 5 entries with pair set. And the second evsel has a collapsed entry so that the total number is 9 - I made it in order to simulate more realistic case. Thus after hists__link the first entry will have 14 entries - 5 are common (w/ pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair). And the second entry will have 9 entries all have its pair.

For matching and/or linking hist entries, they need to be sorted by given sort keys. However current hists__match/link did this on the output trees, so that the entries in the output tree need to be resort before doing it. This looks not so good since we have trees for collecting or collapsing entries before passing them to an output tree and they're already sorted by the given sort keys. Since we don't need to print anything at the time of matching/linking, we can use these internal trees directly instead of bothering with double resort on the output tree. Its only user - at the time of this writing - perf diff can be easily converted to use the internal tree and can save some lines too by getting rid of unnecessary resorting codes.

When comparing entries for collapsing put the given entry first, and then the iterated entry. This is not the case of hist_entry__cmp() when called if given sort keys don't require collapsing. So change the order for the sake of consistency. It will be required for matching and/or linking multiple hist entries.

Dan's smatch found a compare bug with the result of the trace_test_and_set_recursion() and comparing to less than zero. If the function fails, it returns -1, but was saved in an unsigned int, which will never be less than zero and will ignore the result of the test if a recursion did happen. Luckily this is the last of the recursion tests, as the infrastructure of ftrace would catch recursions before it got here, except for some few exceptions.

This patch (as1643b) fixes a build error in ehci-hcd when compiling for ARM with allmodconfig: drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition drivers/usb/host/ehci-mxc.c:280:31: warning: 'ehci_mxc_driver' defined but not used [-Wunused-variable] drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition The fix is to convert ehci-mxc over to the new "ehci-hcd is a library" scheme so that it can coexist peacefully with the ehci-platform driver. As part of the conversion the ehci_mxc_priv data structure, which was allocated dynamically, is now placed where it belongs: in the private area at the end of struct ehci_hcd.

The commit [26a6cb6c: ALSA: hda - Implement a poll loop for jacks as a module parameter] introduced the polling jack detection code, but it also moved the call of snd_hda_jack_set_dirty_all() in the resume path after resume/init ops call. This caused a regression when the jack state has been changed during power-down (e.g. in the power save mode). Since the driver doesn't probe the new jack state but keeps using the cached value due to no dirty flag, the pin state remains also as if the jack is still plugged. The fix is simply moving snd_hda_jack_set_dirty_all() to the original position. Reported-by: Manolo Díaz <diaz.manolo@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

ring_buffer.c use to require declarations from trace.h, but these have moved to the generic header files. There's nothing in trace.h that ring_buffer.c requires. There's some headers that trace.h included that ring_buffer.c needs, but it's best that it includes them directly, and not include trace.h. Also, some things may use ring_buffer.c without having tracing configured. This removes the dependency that may come in the future. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

Using context bit recursion checking, we can help increase the performance of the ring buffer. Before this patch: # echo function > /debug/tracing/current_tracer # for i in `seq 10`; do ./hackbench 50; done Time: 10.285 Time: 10.407 Time: 10.243 Time: 10.372 Time: 10.380 Time: 10.198 Time: 10.272 Time: 10.354 Time: 10.248 Time: 10.253 (average: 10.3012) Now we have: # echo function > /debug/tracing/current_tracer # for i in `seq 10`; do ./hackbench 50; done Time: 9.712 Time: 9.824 Time: 9.861 Time: 9.827 Time: 9.962 Time: 9.905 Time: 9.886 Time: 10.088 Time: 9.861 Time: 9.834 (average: 9.876) a 4% savings!
