-Subject: xen: use maximum reservation to limit amount of usable RAM
-
-From: David Vrabel <david.vrabel@citrix.com>
-
-commit d312ae878b6aed3912e1acaaf5d0b2a9d08a4f11 upstream.
-
-Use the domain's maximum reservation to limit the amount of extra RAM
-for the memory balloon. This reduces the size of the pages tables and
-the amount of reserved low memory (which defaults to about 1/32 of the
-total RAM).
-
-On a system with 8 GiB of RAM with the domain limited to 1 GiB the
-kernel reports:
-
-Before:
-
-Memory: 627792k/4472000k available
-
-After:
-
-Memory: 549740k/11132224k available
-
-A increase of about 76 MiB (~1.5% of the unused 7 GiB).  The reserved
-low memory is also reduced from 253 MiB to 32 MiB.  The total
-additional usable RAM is 329 MiB.
-
-For dom0, this requires at patch to Xen ('x86: use 'dom0_mem' to limit
-the number of pages for dom0') (c/s 23790)
