Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it

Attached are the patches to support super page with EPT. We only support 2M size. And shadow may still work fine with 4K pages. The patches can be split into 3 parts. Apply order is as attached. tool.diff To allocate 2M physical contiguous memory in guest except the first 2M and the last 2M. The first 2M covers special memory, and Xen use the last few pages in guest memory to do special

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See
