Subject: [PATCH v6 00/23] Trace file version 7 - sections
Date: Thu, 2 Dec 2021 14:21:29 +0200 [thread overview]
Message-ID: <20211202122152.43275-1-tz.stoyanov@gmail.com> (raw)
Introduce the next version of the trace-cmd trace file - 7. Major changes
since version 6 is more flexible extendable structure of the file, based on
independent sections.
Known issues:
- Only trace-cmd record and report subcommands work with trace file v7.
This patch-set depends on:
"[PATCH 0/5] Cleanups of tracecmd_output_ APIs"
https://lore.kernel.org/linux-trace-devel/20211202121949.43084-1-tz.stoyanov@gmail.com/
v6 changes:
- Rebased on top of the latest master.
- On trace file v7 close, write any unsaved options in the file - as
a last section.
- Removed the patch "Do not write CPUs with empty trace data" from the
patch set. Empty CPUs are written in v7 trace files, the same way as in
v6.
v5 changes:
- Rebased on top of the latest master.
v4 changes:
- Rebased on top of the latest master.
v3 changes:
- Fixed issues of split and convert commands with some corner cases.
v2 changes:
- Code cleanups.
