* crosvm: aarch64: get kernel's preferred target type for vcpusSonny Rao2018-04-03
| | | | | | | | | | | | | | | | | | | | This fixes an issue on kevin where if we start on a little core, the kernel doesn't like the generic ARMv8 target cpu type for some reason. To fix this we must query the preferred type from the vm device first and supply that to the vcpu init ioctl. We need to change the signature of the configure_vcpu method to pass in the vm object even though we aren't using it on x86.

* kvm: fix fetching irqchip state for PICs other than the first oneDmitry Torokhov2018-03-30
| | | | | | | | | | | | | | | | The KVM API to fetch interrupt controller state expects caller to supply number (id) of the interrupt controller number in which state the caller is interested. To allow crosvm to fetch the correct state and to improve type safety we split the API into one that handles the PIC (primary and secondary) and the one that handles IOAPIC.

* sys_util: Add guest_memoryDylan Reid2017-05-25
| | | | | | | | | | | | | | Add a module for accessing guest memory. This module will replace all the slices that are used to access it currently as those slices aren't valid because the memory is volatile and a volatile slice doesn't exist in rust. Modify the existing users so they no longer depend on the deprecated slice access.
