Subject: [PATCH 0/5] Add support for opening trace.dat files with multuiple buffers
Date: Mon, 27 Jul 2020 10:18:18 +0300 [thread overview]
Message-ID: <20200727071823.169962-1-tz.stoyanov@gmail.com> (raw)
From: "Tzvetomir (VMware) Stoyanov" <tz.stoyanov@gmail.com>
Ftrace supports parallel tracing in isolated ring buffers. Trace-cmd
also supprts this ftrace functionality, it saves the data from all
buffers into single trace.dat file. When such file is opened by
KernelShark, it loads the tracing data only from the top biffer.
Support for loading data from all buffers, located in a single trace.dat
file, is added. Each buffer is loaded as different KernelShark session.
Tzvetomir (VMware) Stoyanov (5):
KernelShark: Add stream name
KernelShark: Fix compilation issues on Fedora 32
KernelShark: Fix combo plot plugin crash in case of multiple streams
KernelShark: Load trace.dat file with ftrace sub-buffers
KernelShark: New libkshark API for loading all entries from given file
