Message-Id: <1409834326-29287-1-git-send-email-jgross@suse.com> Date: Thu, 4 Sep 2014 14:38:43 +0200 From: Juergen Gross <jgross@...e.com> To: linux-kernel@...r.kernel.org, xen-devel@...ts.xensource.com, konrad.wilk@...cle.com, boris.ostrovsky@...cle.com, david.vrabel@...rix.com, jbeulich@...e.com Cc: Juergen Gross <jgross@...e.com> Subject: [PATCH 0/3] xen: remove memory limits from pv-domains When a Xen pv-domain is booted the initial memory map contains multiple objects in the top 2 GB including the initrd and the p2m list. This limits the supported maximum size of the initrd and the maximum initial memory size is limited to about 500 GB. Xen however supports loading the initrd without mapping it and the initial p2m list can be mapped by Xen to an arbitrary selected virtual address. The following patches activate those options and thus remove the limitations.
