Subject: [PATCH 00/15] xen: use tracing to replace ad-hoc debug/stats stuff
Date: Mon, 20 Jun 2011 15:14:56 -0700 [thread overview]
Message-ID: <cover.1308607697.git.jeremy.fitzhardinge@citrix.com> (raw)
From: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
Hi all,
This series (RFC for 3.1) introduces a set of trace events to keep
track of what's going on within the Xen code. This allows us to
replace a pile of ad-hoc debug and stats code.
The latter part of the series implements some improvements the better
tracing highlighted, specifically to reduce hypercall overhead by
making multicalls cheaper and to increase the multicall batch size.
Also at git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git upstream/xen-tracing2
Thanks,
J
