Christoffer Dall 342cd0ab0e KVM: ARM: Hypervisor initialization ... Sets up KVM code to handle all exceptions taken to Hyp mode. When the kernel is booted in Hyp mode, calling an hvc instruction with r0 pointing to the new vectors, the HVBAR is changed to the the vector pointers. This allows subsystems (like KVM here) to execute code in Hyp-mode with the MMU disabled. We initialize other Hyp-mode registers and enables the MMU for Hyp-mode from the id-mapped hyp initialization code. Afterwards, the HVBAR is changed to point to KVM Hyp vectors used to catch guest faults and to switch to Hyp mode to perform a world-switch into a KVM guest. Also provides memory mapping code to map required code pages, data structures, and I/O regions accessed in Hyp mode at the same virtual address as the host kernel virtual addresses, but which conforms to the architectural requirements for translations in Hyp mode. This interface is added in arch/arm/kvm/arm_mmu.c and comprises: - create_hyp_mappings(from, to); - create_hyp_io_mappings(from, to, phys_addr); - free_hyp_pmds(); Reviewed-by: Will Deacon <will.deacon@arm.com> Reviewed-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Christoffer Dall <c.dall@virtualopensystems.com>		2013-01-23 13:29:10 -05:00
