I forgot one conversion, which got noticed by Thomas when running: $ perf stat -e '{cpu-clock,instructions}' kill kill: not enough arguments Segmentation fault (core dumped) $ Fix it, those stats are in evsel->stats, not anymore in evsel->priv.

Using the shell function for perl CFLAGS retrieval instead of back quotes (``). Both execute shell with the command, but the latter is more explicit and seems to be the preferred way. Also we don't have any other use of the back quotes in perf Makefiles. Signed-off-by:

Currently if trace_event__register_resolver() fails, we return -errno, but we can't be sure that errno isn't zero in this case. Signed-off-by:

Use a typed enum for the perf_evsel_config_term type enum. This allows gcc to do much stronger type checks, and also check for missing case statements. I removed the unused _MAX member from the number. It found one missing case. I'm not sure it's a real problem, so I just turned it into a BUG_ON for now. Signed-off-by:

The Intel PMU event aliases have a implicit period= specifier to set the default period. Unfortunately this breaks overriding these periods with -c or -F, because the alias terms look like they are user specified to the internal parser, and user specified event qualifiers override the command line options. Track that they are coming from aliases by adding a "weak" state to the term. Any weak terms don't override command line options. I only did it for -c/-F for now, I think that's the only case that's broken currently. Before: $ perf record -c 1000 -vv -e uops_issued.any ... { sample_period, sample_freq } 2000003 After: $ perf record -c 1000 -vv -e uops_issued.any ... { sample_period, sample_freq } 1000 Signed-off-by: -

Two more, that were just in perf/core and thus weren't covered by Ingo's latest headers synch, kcmp.h and prctl.h, silencing this: Warning: Kernel ABI header at 'tools/include/uapi/linux/kcmp.h' differs from latest version at 'include/uapi/linux/kcmp.h' Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h' Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-2a0r7iybyqpkftllyy5t9hfk@git.kernel.orgSigned-off-by:

Align source with offset lines, which are more advanced, because of the address column.

I'll send script support separately. Committer note: Do not use a fixed column width for the addresses, as kernel ones se more than 10 columns, look at the last offset and get the right width.

Add symbol__calc_percent function, that calculates annotation data for symbol and put the data in the struct annotation_line::samples array. Committer notes: Made symbol__calc_percent non static to be used in the next two patches, which will get some fixups from jolsa, doing it this way to keep this bisectable. Signed-off-by:

Changing the way the annotation lines are allocated and adding annotation_line__(new|delete) functions to deal with this. Before the allocation schema was as follows: ----------------------------------------------------------- struct disasm_line | struct annotation_line | private space ----------------------------------------------------------- Where the private space is used in TUI code to store computed annotation data for events. The stdio code computes the data on the fly. The goal is to compute and store annotation line's data directly in the struct annotation_line itself, so this patch changes the line allocation schema as follows: ------------------------------------------------------------ privsize space | struct disasm_line | struct annotation_line ------------------------------------------------------------ Moving struct annotation_line to the end, because in following changes we will move here the non-fixed length event's data.
