[Qemu-devel] [PATCH 0/3] preliminaries for GICv3 virt support

[Peter Maydell <peter.maydell@linaro.org>]

This set of three 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)

I actually have almost all of the GICv3 virt code written,
but it currently has bugs which mean that a guest kernel
under KVM won't boot. Debugging in progress...

thanks
