Subject: [PATCH 00/20] Trace file version 7 - compression
Date: Mon, 13 Sep 2021 15:41:43 +0300 [thread overview]
Message-ID: <20210913124203.3677760-1-tz.stoyanov@gmail.com> (raw)
Introduced compression of the metadata and trace data in trace files version
7. The compression is optional and disabled by default. A new parameter of
"trace-cmd record" is introduced, which can be used to configure the trace
file compression:
--compression < none / any / name of the desired algorithm >
This patch-set depends on "[PATCH v2 00/25] Trace file version 7 - sections",
should be applied on top of it:
