perf ui/stdio: Align column header for hierarchy output

2016-02-24T23:21:12+00:00

The hierarchy output mode is to group entries so the existing columns won't fit to the new output. Treat all sort keys as a single column and separate headers by "/". # Overhead Command / Shared Object # ........... ................................ # 15.11% swapper 14.97% [kernel.vmlinux] 0.09% [libahci] 0.05% [iwlwifi] ...

perf tools: Make binary data printer code in trace_event public available

2016-02-24T14:38:01+00:00

Move code printing binray data from trace_event() to utils.c and allows passing different printer. Further commits will use this logic to print bpf output event.

tools lib api fs: Adopt filename__read_str from perf

2016-02-16T20:12:56+00:00

We already moved similar functions in here, also it'll be useful for sysfs__read_str addition in following patch.

perf tools: Move timestamp creation to util

2016-01-29T20:30:06+00:00

Timestamp generation becomes a public available helper. Which will be used by 'perf record', help it output to split output file based on time. For example: perf.data.2015122620363710 perf.data.2015122620364092 perf.data.2015122620365423 ...

perf symbols: Do not read symbols/data from device files

2016-01-26T14:52:43+00:00

With mem sampling we could get data source within mapped device file. Processing such sample would block during report phase on trying to read the device file. Chacking for device files and skip the processing if it's detected.
