From bd200384c515bdc84d52f1735c0fea43c8f61e11 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 9 Oct 2019 14:51:54 +0100 Subject: trace: add --group=all to tracing.txt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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") Buglink: https://bugs.launchpad.net/bugs/1844814 Reported-by: Philippe Mathieu-Daudé Reviewed-by: Daniel P.
