[PATCH v2 0/5] hvf: arm: add experimental VHE (x-vhe) toggle

Posted by Mohamed Mediouni 3 weeks, 1 day ago

macOS 27.0 has a pre-release VHE implementation. Add support for it in QEMU.

The first patch in the series is an independent bugfix that should be backported to QEMU 11.1 too.

v2:

Add:
hvf: arm: expose E2H0
hvf: arm: ignore accesses to CNTKCTL_EL12

This is to have working KVM under the VHE configuration.

Mohamed Mediouni (5):
  hvf: arm: advertise ID_AA64PFR0_EL1.GIC
  hvf: arm: add experimental VHE toggle
  hvf: arm: advertise EL3 support when VHE is on
  hvf: arm: expose E2H0
  hvf: arm: ignore accesses to CNTKCTL_EL12
