Subject: [PULL 1/2] trace: add --group=all to tracing.txt
Date: Mon, 14 Oct 2019 09:57:08 +0100 [thread overview]
Message-ID: <20191014085709.26812-2-stefanha@redhat.com> (raw)
In-Reply-To: <20191014085709.26812-1-stefanha@redhat.com>
tracetool needs to know the group name ("all", "root", or a specific
subdirectory). Also remove the stdin redirection because tracetool.py
needs the path to the trace-events file. Update the documentation.
Fixes: 2098c56a9bc5901e145fa5d4759f075808811685
("trace: move setting of group name into Makefiles")

To facilitate simple usage of systemtap where there merely needs to be printf
logging of certain probes, a helper script "qemu-trace-stap" is provided.
