[Qemu-devel] [PATCH v2 0/4] preliminaries for GICv3 virt support

[Peter Maydell]

This set of straightforward patches is a preliminary
for adding virtualization support to the GICv3 emulation:
 * add a (nop implementation of) MDCCINT_EL1, since KVM
   will read/write it on worldswitch
 * fix some bugs in the GICv3 trace events
 * add trace events for the generic timers
   (which I have been using for debugging)
 * add trace events for the serial port (again, debug use)

Changes v1->v2:
 * added the missing target-arm/trace-events file to
   patch 2
 * new patch 4 with pl011 trace events

Peter Maydell (4):
  target-arm: Implement dummy MDCCINT_EL1
  target-arm: Add trace events for the generic timers
  hw/intc/arm_gicv3: Fix ICC register tracepoints
  hw/char/pl011: Add trace events
