[Xen-devel] [PATCH 0/3] xen/arm: Inject an exception to the guest rather than crashing it

Hi all,

This small series replaces all call to domain_crash_synchronous by injecting
an exception to the guest.

This will result to a nicer trace from the guest (no need to manually walk
the stack) and give a chance to the guest to give a bit more information on
what it was doing.


Julien Grall (3):
  xen/arm: io: Distinguish unhandled IO from aborted one
  xen/arm: Don't crash domain on bad MMIO emulation
  xen/arm: Don't crash the domain on invalid HVC immediate
