Subject: [Qemu-devel] [RFC] Add a stp file for usage from build directory
Date: Sun, 26 May 2013 22:19:06 -0400	[thread overview]
Message-ID: <1369621146-17095-1-git-send-email-alevy@redhat.com> (raw)

For systemtap the location of the process being tapped is crucial, so
the existing stp file requires installation to use. A new file providing
qemu.local prefixed probes lets scripts run without an install step.
