Subject: [PATCH v4 9/9] tools: arm: increase size of region set aside for guest grant table
Date: Tue, 13 May 2014 12:29:33 +0100 [thread overview]
Message-ID: <1399980574-12515-9-git-send-email-ian.campbell@citrix.com> (raw)
In-Reply-To: <1399980488.21867.19.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.
