Subject: [PATCH V2 0/6] perf tools: Enable AUX area tracing snapshots using a FIFO
Date: Tue,  1 Sep 2020 12:37:52 +0300	[thread overview]
Message-ID: <20200901093758.32293-1-adrian.hunter@intel.com> (raw)

Hi

Here are V2 patches to enable AUX area tracing snapshots using a FIFO.
Presently SIGUSR2 can be used but the advantage of the FIFO is that access
is governed by access to the FIFO.  Refer to the example in patch 5.

The first 4 patches are preparation, including patch 4 which enhances the
--control option to accept file names.

Patch 5 adds snapshot control command.

The final patch updates Intel PT documentation.


Changes in V2:
	Use fifo: prefix in --control option


Adrian Hunter (6):
      perf tools: Consolidate --control option parsing into one function
      perf tools: Handle read errors from ctl_fd
      perf tools: Use AsciiDoc formatting for --control option documentation
      perf tools: Add FIFO file names as alternative options to --control
      perf record: Add 'snapshot' control command
      perf intel-pt: Document snapshot control command
