If the vgic needs to inject a virtual irq into the guest, but no free LR registers are available, add the irq to a list and return. Whenever an LR register becomes available we add the queued irq to it and remove it from the list. We use the gic lock to protect the list and the bitmask.

Hi all, this small patch series implement guest SMP support for ARM, using the ARM PSCI interface for secondary cpu bringup. Stefano Stabellini (4): xen/arm: basic PSCI support, implement cpu_on xen/arm: support for guest SGI xen/arm: support vcpu_op hypercalls xen: move VCPUOP_register_vcpu_info to common code xen/arch/arm/domain.c | 66 ++++++++++++++++++++++++

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
