[Xen-devel] [PATCH] xen/arm: implement GICD_ICACTIVER read/write

2015-11-25 Thread Stefano Stabellini
Implement GICD_ICACTIVER and GICD_ISACTIVER reads by looking for the GIC_IRQ_GUEST_ACTIVE bit in the relevant struct pending_irq. However given that the pending to active transaction for irqs in LRs in done in hardware, the GIC_IRQ_GUEST_ACTIVE bit might be out of date. We'll have to live with that
