v6 changes: - Check compiler before using [0] or []. v5 changes: - Fix prototypes in v4v.h for do_v4v_op - Add padding to make sure all the structures are 64 bits aligned - Replace [0] with [] v4 changes: - Stop using ssize_t, use long instead - Return -MSGSIZE for message bigger than 2GB - Fixup size handling - Rename

The guest handle checks should use paging_* predicates, not shadow_*. Also tidy up a few places where p2m definitions were being imported via asm/guest_access.h -> asm/shadow.h -> asm/p2m.h Signed-off-by: Tim Deegan <Tim.Deegan@citrix.com> -- Tim Deegan <Tim.Deegan@citrix.com> Principal Software Engineer, Citrix Systems (R&D) Ltd.

Hi all, this patch series introduces support for runstate_memory_area on ARM. The first patch moves VCPUOP_register_runstate_memory_area to common code, while the second one add VCPUOP_register_runstate_memory_area to the whilelist of vcpu_op hypercalls supported on ARM and properly updates the runstate_memory_area during vcpu context switch.

Hi all, this patch series makes the necessary changes to make sure that the current ARM hypercall ABI can be used as-is on 64 bit ARM platforms: - it defines xen_ulong_t as uint64_t on ARM; - it introduces a new macro to handle guest pointers, called XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to have size 8 bytes on aarch64); - it replaces all the occurrences of

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

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
