hexagon architecture system emulation: part 1/3 These patches are also staged in my tree (branch "hex-next" at https://github.com/quic/qemu/). After these three patch series, we're able to run the test suite for minivm [1]. minivm is a hypervisor, an implementation of the Hexagon Virtual Machine Specification.
