Subject: [PATCH v4 5/5] trace-cmd: Add initial infrastructure for trace-cmd specific plugins.
Date: Fri, 4 Oct 2019 16:36:47 +0300 [thread overview]
Message-ID: <20191004133647.27759-6-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20191004133647.27759-1-tz.stoyanov@gmail.com>
Create a new directory lib/trace-cmd/plugins, where the libtracecmd
plugins will be placed. Plugins compilation is integrated in
the trace-cmd build process. New plugins are installed in
$(HOME)/.local/lib/trace-cmd/plugins or $(libdir)/trace-cmd/plugins directories.
Current python_plugin.so is part of libtraceevent plugins, so the python
plugins path is changed from
$(HOME)/.trace-cmd/python to $(HOME)/.local/lib/traceevent/python
and
$(libdir)/trace-cmd/python to $(libdir)/traceevent/python
Added an initial set of APIs for working with trace-cmd plugins.
