Currently the srcline sort key compares ip rather than srcline info. I guess this was due to a performance reason to run external addr2line utility. Now we have implemented the functionality inside, use the srcline info when comparing hist entries. Also constantly print "??:0" string for unknown srcline rather than printing ip. Signed-off-by:

When the srcline sort key is used , the external addr2line utility needs to be run for each hist entry to get the srcline info. This can consume quite a time if one has a huge perf.data file. So rather than executing the external utility, implement it internally and just call it. We can do it since we've linked with libbfd already. Signed-off-by:

Running "perf top" on a machine with possibly invalid or non-matching vmlinux at the various places results in no symbol resolving despite /proc/kallsyms being present and valid. Add a new option --ignore-vmlinux to explicitly indicate that we do not want to use these kernels and just use what we have (kallsyms). Signed-off-by:

Adding possibility to specify mmap size via -m/--mmap-pages by appending unit size character (B/K/M/G) to the number, like: $ perf record -m 8K ls $ perf record -m 2M ls The size is rounded up appropriately to follow perf mmap restrictions.

While perf-lock currently reports both the total wait time and the number of contentions, it doesn't explicitly show the average wait time. Having this value immediately in the report can be quite useful when looking into performance issues. Furthermore, allowing report to sort by averages is another handy feature to have - and thus do not only print the value, but add it to the lock_stat structure. Signed-off-by:

This function should be straightforward, and we can remove some trivial logic by moving the functionality of read_events() into __cmd_report() - thus allowing a new session to be properly deleted. Since the 'info' subcommand also needs to process the recorded events, add a 'display_info' flag to differentiate between report and info commands. Furthermore, this patch also calls perf_session__has_traces(), making sure that we don't compare apples and oranges, fixing a segfault when using an perf.data file generated by a different subcommand. ie: ./perf mem record sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.017 MB perf.data (~724 samples) ] ./perf lock report Segmentation fault (core dumped) Signed-off-by:
