The name "domain" is quite confusion in Xen. Hope I didn''t miss anything... -- regards Yang, Sheng _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, This is the fifth version of this patch series. With the Versatile Express TC2, it''s possible to boot only with A7 or A15. If the user choose to boot with only A7, the CPU ID will start at 0x100. As Xen relies on it to set the logical ID and the GIC, it won''t be possible to use Xen with this use case. This patch series is divided in 3 parts: - Patch 1: prepare Xen

We used to have use a single parent for all DMA operations. This tends to complicate the mdev based hardware virtio datapath offloading which may not implement the control path over datapath like ctrl vq in the case of virtio-net. So this series tries to intorduce per DMA domain by allowing trasnport to specify the parent device for each virtqueue. Then for the case of virtio-mdev device, it can

Hi Andi, This series of patches updates paravirt_ops in various ways. Some of the changes are plain cleanups and improvements, and some add some interfaces necessary for Xen. The brief overview: add-MAINTAINERS.patch - obvious remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed paravirt-nop.patch - mark nop operations consistently paravirt-pte-accessors.patch - operations to pack/unpack
