The validation checks that the values that were just assigned, got assigned i.e. the error can't ever happen. Subsequent patches will call this code in places where errors are not being returned. Changing those code paths to return this non-existent error is counter-productive, so just remove it. That in turn results in perf_evlist__set_maps not needing to return an error, but callers aren't checking it either, so remove that too. Signed-off-by:

Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/urgent fixes from Arnaldo Carvalho de Melo: - In some cases where perf_event.fork.{pid,tid} should be used we were instead using perf_event.comm.{pid,tid}, which is not a problem for for the 'pid' case, that sits in the same place in these union_perf_event members, but comm.tid sits where fork.ppid is, oops. These cases were considered as (potentially) problematic: - 'perf script' with !sample_id_all, i.e. only non old kernels without perf_event_attr.sample_id_all. - intel_pt could be affected when decoding without timestamps, as the exit event is only used to flush out data which anyway gets flushed at the end of the session. - intel_bts also uses the exit event to flush data which would probably not cause errors as it would get flushed at the end of the session instead. Fix it. (Adrian Hunter) - Due to relaxing the compiler checks for bison generated files, we missed updating one parse_events_add_pmu() caller when this function had its prototype changed, fix it.

Adrian Hunter authored
In a couple of cases the 'comm' member of 'union event' has been used instead of the correct member ('fork') when processing exit events. In the cases where it has been used incorrectly, only the 'pid' and 'tid' are affected. The 'pid' value would be correct anyway because it is in the same position in 'comm' and 'fork' events, but the 'tid' would have been incorrectly assigned from 'ppid'. However, for exit events, the kernel puts the current task in the 'ppid' and 'ttid' which is the same as the exiting task. That is 'ppid' == 'pid' and if the task is not multi-threaded, 'pid' == 'tid' i.e. the data goes wrong only when tracing multi-threaded programs. It is hard to find an example of how this would produce an error in practice. There are 3 occurences of the fix: 1. perf script is only affected if !sample_id_all which only happens on old kernels. 2. intel_pt is only affected when decoding without timestamps and would probably still decode correctly - the exit event is only used to flush out data which anyway gets flushed at the end of the session 3. intel_bts also uses the exit event to flush data which would probably not cause errors as it would get flushed at the end of the session instead Signed-off-by:

This patch makes perf compile on non x86 platforms by defining a weak symbol for sample_reg_masks[] in util/perf_regs.c. The patch also moves the REG() and REG_END() macros into the util/per_regs.h header file. The macros are renamed to SMPL_REG/SMPL_REG_END to avoid clashes with other header files. Signed-off-by:

Pull scheduler updates from Ingo Molnar: "The biggest change in this cycle is the rewrite of the main SMP load balancing metric: the CPU load/utilization. The main goal was to make the metric more precise and more representative - see the changelog of this commit for the gory details: 9d89c257 ("sched/fair: Rewrite runnable load and utilization average tracking") It is done in a way that significantly reduces complexity of the code: 5 files changed, 249 insertions(+), 494 deletions(-) and the performance testing results are encouraging.

(Wang Nan) - Add Intel BTS support, with a call-graph script to show it and PT in use in a GUI using 'perf script' python scripting with postgresql and Qt. (Adrian Hunter) - Allow selecting the type of callchains per event, including disabling callchains in all but one entry in an event list, to save space, and also to ask for the callchains collected in one event to be used in other events. (Kan Liang) - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho de Melo) * A bunch more translate file/pathnames from pointers to strings. * Convert numbers to strings for the 'keyctl' syscall 'option' arg. * Add missing 'clockid' entries. - Introduce 'srcfile' sort key: (Andi Kleen) # perf record -F 10000 usleep 1 # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile <SNIP> # Overhead Source File 26.49% copy_page_64.S 5.49% signal.c 0.51% msr.h # It can be combined with other fields, for instance, experiment with '-s srcfile,symbol'. There are some oddities in some distros and with some specific DSOs, being investigated, so your mileage may vary. - Support per-event 'freq' term: (Namhyung Kim) $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1 $ perf evlist -F cpu/instructions,freq=1234/: sample_freq=1234 cycles: sample_period=1000 $ - Deref sys_enter pointer args with contents from probe:vfs_getname, showing pathnames instead of pointers in many syscalls in 'perf trace'. (Arnaldo Carvalho de Melo) - Stop collecting /proc/kallsyms in perf.data files, saving about 4.5MB on a typical x86-64 system, use the the symbol resolution routines used in all the other tools (report, top, etc) now that we can ask libtraceevent to use perf's symbol resolution code. (Arnaldo Carvalho de Melo) - 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.
