Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: New features: - Allow filtering out of perf's PID via 'perf record --exclude-perf'. (Wang Nan) - 'perf trace' now supports syscall groups, like strace, i.e: $ trace -e file touch file Will expand 'file' into multiple, file related, syscalls. More work needed to add extra groups for other syscall groups, and also to complement what was added for the 'file' group, included as a proof of concept. (Arnaldo Carvalho de Melo) - Add lock_pi stresser to 'perf bench futex', to test the kernel code related to FUTEX_(UN)LOCK_PI. (Davidlohr Bueso) User visible fixes: - Apply --filter to all events in a glob matching, not just the last one. (Wang Nan) Documentation changes: - Document setting '-e pmu/period=N/' in the 'perf record' man page. (Kan Liang) Infrastructure changes: - 'perf probe' code simplifications and movements to separate files. (Masami Hiramatsu) - Fix makefile generation under 'dash'.

Davidlohr Bueso authored
Allows a way of measuring low level kernel implementation of FUTEX_LOCK_PI and FUTEX_UNLOCK_PI. The program comes in two flavors: (i) single futex (default), all threads contend on the same uaddr. For the sake of the benchmark, we call into kernel space even when the lock is uncontended. The kernel will set it to TID, any waters that come in and contend for the pi futex will be handled respectively by the kernel. (ii) -M option for multiple futexes, each thread deals with its own futex. This is a trivial scenario and only measures kernel handling of 0->TID transition.

Wang Nan authored
This patch allows 'perf record' to exclude events issued by perf itself by '--exclude-perf' option. Before this patch, when doing something like: # perf record -a -e syscalls:sys_enter_write <cmd> One could easily get result like this: # /tmp/perf report --stdio ... # Overhead Command Shared Object Symbol # ........ ....... .................. .................... # 99.99% perf libpthread-2.18.so [.] __write_nocancel 0.01% ls libc-2.18.so [.] write 0.01% sshd libc-2.18.so [.] write ... Where most events are generated by perf itself. A shell trick can be done to filter perf itself out: # cat << EOF > ./tmp > #!/bin/sh > exec perf record -e ... --filter="common_pid != \$\$" -a sleep 10 > EOF # chmod a+x ./tmp # ./tmp However, doing so is user unfriendly. This patch extracts evsel iteration framework introduced by patch 'perf record: Apply filter to all events in a glob matching' into foreach_evsel_in_last_glob(), and makes exclude_perf() function append new filter expression to each evsel selected by a '-e' selector. To avoid losing filters if user pass '--filter' after '--exclude-perf', this patch uses perf_evsel__append_filter() in both case, instead of perf_evsel__set_filter() which removes old filter. As a side effect, now it is possible to use multiple '--filter' option for one selector. They are combinded with '&&'.

There is an old problem in perf's filter applying which first posted at Sep. 2014 at https://lkml.org/lkml/2014/9/9/944 that, if passing multiple events in a glob matching expression in cmdline then add '--filter' after them, the filter will be applied on only the last one. For example: # dd if=/dev/zero of=/dev/null & [1] 464 # perf record -a -e 'syscalls:sys_*_read' --filter 'common_pid != 464' sleep 0.1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.239 MB perf.data (2094 samples) ] # perf report --stdio | tee ... # Samples: 2K of event 'syscalls:sys_enter_read' # Event count (approx.): 2092 ... # Samples: 2 of event 'syscalls:sys_exit_read' # Event count (approx.): 2 ... In this example, filter only applied on 'syscalls:sys_exit_read', and there's no way to set filter for ''syscalls:sys_enter_read'. This patch adds a 'cmdline_group_boundary' for 'struct evsel', and apply filter on all events between two boundary marks. After applying this patch: # perf record -a -e 'syscalls:sys_*_read' --filter 'common_pid != 464' sleep 0.1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.031 MB perf.data (3 samples) ] # perf report --stdio | tee ... # Samples: 1 of event 'syscalls:sys_enter_read' # Event count (approx.): 1 ... # Samples: 2 of event 'syscalls:sys_exit_read' # Event count (approx.): 2 ...

So, if we have an strlist equal to: "file,close" And we call it as: struct strlist_config *config = { .dirname = "~/strace/groups", }; struct strlist *slist = strlist__new("file, close", &config); And we have: $ cat ~/strace/groups/file access open openat statfs Then the resulting strlist will have these contents: [ "access", "open", "openat", "statfs", "close" ] This will be used to implement strace syscall groups in 'perf trace', but can be used in some other tool, thus being implemented in 'strlist'.

Migrate avr32 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. We want to call cpu_idle_poll_ctrl() in shutdown only if we were in oneshot or resume state earlier. Create another variable to save this information and check that in shutdown callback.

(by Dave Hansen) - Fix various NMI handling related bugs unearthed by the big asm code rewrite and generally make the NMI code more robust and more maintainable while at it. These changes are a bit late in the cycle, I hope they are still acceptable.

Pull rtc fixes from Alexandre Belloni: "A few fixes for the RTC susbsystem for 4.2. The mt6397 driver was introduce in 4.2 so it is worth fixing before the final release. I though the compilation warning for armada38x was fixed by akpm in commit f98b733e ("rtc-armada38x.c: remove unused local `flags'") but he actually missed some occurrences of the variables. Since I received 4 patches for that, I think we can include it now. Summary: - fix mt6397 wakealarm creation - remove a compilation warning for armada38x that was forgotten" * tag 'rtc-v4.2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: rtc: armada38x: Remove unused variable from armada38x_rtc_set_time() rtc: mt6397: enable wakeup before registering rtc device
