* arm_gic: Fix GIC pending behaviorChristoffer Dall2014-02-082-18/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing implementation of the pending behavior in gic_set_irq, gic_complete_irq, and the distributor pending set/clear registers does not follow the semantics of the GICv2.0 specs, but may implement the 11MPCore support. Therefore, maintain the existing semantics for 11MPCore and v7M NVIC and change the behavior to be in accordance with the GICv2.0 specs for "generic implementations" (s->revision == 1 || s->revision == 2). Generic implementations distinguish between setting a level-triggered interrupt pending through writes to the GICD_ISPENDR and when hardware raises the interrupt line. Writing to the GICD_ICPENDR will not cause the interrupt to become non-pending if the line is still active, and conversely, if the line is deactivated but the interrupt is marked as pending through a write to GICD_ISPENDR, the interrupt remains pending. Handle this situation in the GIC_TEST_PENDING (which now becomes a static inline named gic_test_pending) and let the 'pending' field correspond only to the latched state of the D-flip flop in the GICv2.0 specs Figure 4-10. The following changes are added: gic_test_pending: Make this a static inline and split out the 11MPCore from the generic behavior. For the generic behavior, consider interrupts pending if: ((s->irq_state[irq].pending & (cm) != 0) || (!GIC_TEST_EDGE_TRIGGER(irq) && GIC_TEST_LEVEL(irq, cm)) gic_set_irq: Split out the 11MPCore from the generic behavior. For the generic behavior, always GIC_SET_LEVEL() on positive level, but only GIC_SET_PENDING for edge-triggered interrupts and always simply GIC_CLEAR_LEVEL() on negative level. gic_complete_irq: Only resample the line for line-triggered interrupts on an 11MPCore. Generic implementations will sample the line directly in gic_test_pending().

This will simplify the kvm_cpu_fill_host() code a little. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> [Remove unparseable comment. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
