Subject: [PATCH v3 0/5] trace-cmd: split: Handle splitting files with multiple instances
Date: Tue, 23 Jan 2024 14:42:10 +0100	[thread overview]
Message-ID: <20240123134215.385415-1-pierre.gondois@arm.com> (raw)

V3:
- Add error handling for strdup() calls.
- Fix bug described at [2]: the split command kept generating
  split files forever when the '-r' option was provided.
  A new handle was used in each loop, meaning the input file was
  being parsed again from the beginning.
- Remove the 2 first patch accepted in v2.
V2:
- Add 'trace-cmd split: Enable support for buffer selection' to
  handle instance selection with the 'trace-cmd' split command.
- Rename patches as 'trace-cmd: split' -> 'trace-cmd split'.
- Correctly free allocated memory in different lists.

Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=218357

Splitting trace files having multiple buffer instances discards
side-buffers . I.e., only the main buffer is preserved in the
resulting split trace files. This patch-set intends to fix this.

As a continuation of the bugzilla, support to allow selecting
buffer instances is added to the 'trace-cmd split' command [1].
This support implies adding new '-B/--top' parameters.

Also:
- Fix a side issue preventing to provide start/end timestamps
  along with a time-window parameters.
- Update trace-cmd split usage
