perf report: Allow configuring the default sort order in ~/.perfconfig

2016-08-23T18:37:33+00:00

Allows changing the default sort order from "comm,dso,symbol" to some other default, for instance "sym,dso" may be more fitting for kernel developers.

perf hists: Add support for header span

2016-08-23T18:37:33+00:00

Add span argument for header callback function. The handling of this argument is completely in the hands of the callback. The only thing the caller ensures is it's zeroed on the beginning. Omitting span skipping in hierarchy headers and gtk code. The c2c code use this to span header lines based on the entries span configuration.

perf hists: Trim libtraceevent trace_seq buffers

2016-08-09T13:46:56+00:00

When we use libtraceevent to format trace event fields into printable strings to use in hist entries it is important to trim it from the default 4 KiB it starts with to what is really used, to reduce the memory footprint, so use realloc(seq.buffer, seq.len + 1) when returning the seq.buffer formatted with the fields contents.

perf tools: Bail out at "--sort dcacheline" and cacheline_size not known

2016-07-15T13:08:43+00:00

There are cases where further work would be needed to overcome the fact that neither sysconf(_SC_LEVEL1_DCACHE_LINESIZE) nor /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size are available in some systems (Android, for instance), so bail out when such a situation takes place.

perf evlist: Rename for_each() macros to for_each_entry()

2016-06-23T14:26:15+00:00

To match the semantics for list.h in the kernel, that are used to implement those macros.

perf hists: Enlarge pid sort entry size

2016-06-22T12:56:35+00:00

The pid sort entry currently aligns pids with 5 digits, which is not enough for current 4 million pids limit. This leads to unaligned ':' header-data output when we display 7 digits pid: # Children Self Symbol Pid:Command # ........ ........ ...................... ..................... # 0.12% 0.12% [.] 0x0000000000147e0f 2052894:krava ... Adding 2 more digit to properly align the pid limit: # Children Self Symbol Pid:Command # ........ ........ ...................... ....................... # 0.12% 0.12% [.] 0x0000000000147e0f 2052894:krava Signed-off-by: Jiri Olsa Cc: David Ahern Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1466459899-1166-9-git-send-email-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo
