* x86/mm/shadow: remove dead code for avoiding Xen entries on 32-bit tables.Tim Deegan2013-05-091-28/+21
| | | | | | | | | | | | | | | All non-external-mode (==PV) guests have 4-level pagetables now that the PAE build of Xen is gone. This patch should have no effect, since the condition it removes could never be true anyway: the l2 offset of HYPERVISOR_VIRT_START on 64-bit Xen is much higher than any l2 offset we could have seen in the tables (and indeed bigger than the 'int' type, which clang was complaining about). Actual compat PV guest xen entries are handled by the equivalent test in the 64-bit SHADOW_FOREACH_L2E() below.

| | | | | | | | | | | Don't inject irqs to vcpus that are down.

| | | | | | | | | | | | | Introduce a domain wide vtimer initialization function to initialize the phys_timer and the virt_timer offsets.

* xen/arm: run the vtimer Xen timers on the pcpu the vcpu is running onStefano Stabellini2013-05-081-2/+4
| | | | | | | | | | | | The Xen physical timer emulator and virtual timer driver use two internal Xen timers: initialize them on the pcpu the vcpu is running on, rather than the processor that it's creating the vcpu.

* xen/arm: send IPIs to inject irqs into guest vcpus running on different pcpusStefano Stabellini2013-05-081-0/+4
| | | | | | | | | | | If we need to inject an irq into a VCPU that is running on a different processor, we shouldn't just enqueue the irq into the lr_pending and inflight lists and wait for something to interrupt the guest execution. Send an IPI to the target pcpu so that Xen can inject the new interrupt returning to guest.

* xen/gic: EOI irqs on the right pcpuStefano Stabellini2013-05-083-1/+24
| | | | | | | | | | | | | | We need to write the irq number to GICC_DIR on the physical cpu that previously received the interrupt, but currently we are doing it on the pcpu that received the maintenance interrupt. As a consequence if a vcpu is migrated to a different pcpu, the irq is going to be EOI'ed on the wrong pcpu. This covers the case where dom0 vcpu0 is running on pcpu1 for example (you can test this scenario by using xl vcpu-pin).

| | | | | | | | | | | | | | | | | | | | | | | | | | | Trap guest WFI, block the guest VCPU unless it has pending interrupts (WFI should return if any interrupts arrive even if interrupts are disabled). Awake the guest vcpu when a new interrupt for it arrives. Introduce gic_events_need_delivery: it checks whether the current vcpu has any interrupts that need to be delivered either on the lrs or in lr_pending. Properly implement local_events_need_delivery: check if the guest disabled interrupts, if they aren't disabled, return positive if gic_events_need_delivery returns positive. Otherwise we still need to check whether evtchn_upcall_pending is set but no VGIC_IRQ_EVTCHN_CALLBACK irqs are in flight: it could be the race described by commit db453468d92369e7182663fb13e14d83ec4ce456 "arm: vgic: fix race between evtchn upcall and evtchnop_send". If that is the case it means that an event needs to be injected. If all these tests are negative then no events need to be delivered. Implement local_event_delivery_enable by clearing PSR_IRQ_MASK.
