perf evsel: Rename perf_evselenv() to evselenv()

2020-05-05T19:35:31+00:00

As it is a 'struct evsel' method, not part of tools/lib/perf/, aka
libperf, to whom the perf_ prefix belongs.

perf annotate: Add basic support for bpf_image

2020-04-16T15:19:06+00:00

Add the DSO_BINARY_TYPE__BPF_IMAGE dso binary type to recognize BPF
images that carry trampoline or dispatcher.

Upcoming patches will add support to read the image data, store it
within the BPF feature in perf.data and display it for annotation
purposes.

Currently we only display following message:

  # ./perf annotate bpf_trampoline_24456 --stdio
   Percent |      Source code & Disassembly of . for cycles (504  ...
  --------------------------------------------------------------- ...
           :       to be implemented

2020-03-04T13:34:10+00:00

The 'nr_jumps' field in 'struct annotation' is not used since it's
inception in commit 2402e4a936a0 ("perf annotate browser: Show 'jumpy'
functions").  Get rid of it.

perf annotate: Fix segfault with source toggle

2020-02-27T14:47:23+00:00

While rendering annotate browser from perf report tui, we keep track
of total number of lines(asm + source) in annotation->nr_entries and
total number of asm lines in annotation->nr_asm_entries. But we don't
reset them before starting. Thus if user annotates same function
multiple times, we restart incrementing these fields with old values.

This causes a segfault when user tries to toggle source code after
annotating same function multiple times. Fix it.
