Subject: [PATCH 00/25] Trace file version 7 - sections
Date: Fri, 10 Sep 2021 16:50:36 +0300 [thread overview]
Message-ID: <20210910135101.2865226-1-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 00/21] trace-cmd fixes and clean-ups",
should be applied on top of it:
