Subject: [PATCH 03/17] xenpaging: print DPRINTF ouput if XENPAGING_DEBUG is in environment
Date: Mon, 06 Dec 2010 21:59:10 +0100 [thread overview]
Message-ID: <20101206205908.989247205@aepfle.de> (raw)
In-Reply-To: 20101206205907.848643876@aepfle.de
[-- Attachment #1: xen-unstable.xenpaging.xenpaging_init.xentoollog_logger.patch --]
[-- Type: text/plain, Size: 1082 bytes --]
No DPRINTF output is logged because the default loglevel is to low in
libxc. Recognize the XENPAGING_DEBUG environment variable to change the
default loglevel at runtime.
