From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ian Campbell Subject: [PATCH RFC 0/2] Support for spare physical address space on ARM Date: Thu, 31 Jul 2014 11:59:00 +0100 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xen.org Errors-To: xen-devel-bounces@lists.xen.org To: xen-devel Cc: Stefano Stabellini , Julien Grall , Tim Deegan , Roy Franz , Jan Beulich , Fu Wei List-Id: xen-devel@lists.xenproject.org This series refactors the x86 "pdx" stuff (phys address space compression) into common code and makes use of it on ARM. I'm publishing this early since I'm about to mostly disappear until 19 August (I'm in a couple of days next week and that's it) and I hope this will help unblock Roy and Fu Wei's work on UEFI and grub/multiboot a bit. The refactoring patch should be mostly ok but the ARM one is rather incomplete, although it works for me on a 64-bit fast model and real h/w (with both contiguous and sparse memory maps). Note that it is not expected to work at all on 32-bit yet. The code is also available from git://xenbits.xen.org/people/ianc/xen.git pdx-v1 (the branch also includes some incidental bits of my 48-bit physical address series whic I was using for debug) Ian.
