Date: Thu, 13 Oct 2011 15:32:15 -0400 Message-ID: <20111013193214.GC16336@phenom.oracle.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Sender: xen-devel-bounces@lists.xensource.com Errors-To: xen-devel-bounces@lists.xensource.com To: xen-devel@lists.xensource.com, xen-users@lists.xensource.com List-Id: xen-devel@lists.xenproject.org This is what is being currently developed and reviewed. Some of it might be done before 3.2 merge windows opens so it could become part of 3.2: - PV spinlocks. Jeremy has been tirelessly working on this and every time it looks like it is ready somebody comes out and points out a bug in generic code that impacts his work. So this has mushroomed to now include jump_label support (for tracing), compare and exchange atomic operations (for everything), and then the PV spinlocks patches. - ACPI S3 support. The code is going through a review and we need some eyes from the ACPI folks to make sure nothing is wrong. - Graphic support for radeon/nouveau for 32-bit cards (enterprise type). Also known as "TTM DMA pool" code. - Blkback/blkfront features. Expanding the blkback to do amazing things. Like make the code easier to read, expanding the discard support to support REQ_DISCARD_SECURE and also do multipage rings (to allow more I/Os). - microcode update. Well, this one is complex. The x86 maintainers want to re-write how it is done, so the Xen microcode is shelved for right now until that is complete. - cleancache. This is the last piece of tmem - it allows the swap disk to use the temporary memory pool that tmem provides to make the guest run even faster. - Xen ACPI cpufreq patches. They are not yet ready to be posted, but they are slowly taking shape. If I missed somebody's current work, please point me out to it.
