Subject: [PATCH v3 8/8] tools: arm: increase size of region set aside for guest grant table
Date: Mon, 28 Apr 2014 14:02:12 +0100 [thread overview]
Message-ID: <1398690132-5651-8-git-send-email-ian.campbell@citrix.com> (raw)
In-Reply-To: <1398690109.29700.82.camel@kazak.uk.xensource.com>
The current size is sufficient for the default maximum grant table size
(32-frames), but increase the reserved region to 16M/4096 pages to allow for
the use of the gnttab_max_nr_frames command line option.
