Subject: [PATCH] Use ballooned pages for gntdev
Date: Mon, 7 Mar 2011 13:06:45 -0500 [thread overview]
Message-ID: <1299521208-8531-1-git-send-email-dgdegra@tycho.nsa.gov> (raw)
Split up the balloon module, similar to how grants and events are
handled. This allow gntdev to use ballooned pages without adding a
dependency on the balloon module.
The interface is slightly different from that exposed in 2.6.32; the
page vector is allocated by the caller, not by the balloon driver. This
allows more freedom in how the returned pages are used, since they do
not all have to be returned to the balloon driver at the same time. It
also tries to reuse already ballooned pages rather than always
ballooning new pages to ensure they are in low memory as the 2.6.32
version did.

[PATCH 2/3] xen-balloon: Add interface to retrieve ballooned pages
