Hello everyone, this is the very first 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

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen.

There''re basically two methods to enter a given C-state: legacy (hlt + I/O read), and native(using mwait). MWAIT is always preferred when both underlying CPU and OS support, which is a more efficient way to conduct C-state transition. Xen PM relies on Dom0 to parse ACPI Cx/Px information, which involves one step to notify BIOS about a set of capabilities supported by OSPM. One capability

Hello, The following patches are a solution to a problem we have encountered when using the Xen hypervisor: - Need Pxx/Cxx states to save on power consumption when using Xen (we do want those datacenters to consume less power!), - Also need to figure out the Turbo mode so that the scheduler can properly boost a core for CPU bound guests. In essence the Xen hypervisor requires that
