From c992a4f6a9b0a37c8bd7dfc727ecc3fed125c16b Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 14 Mar 2017 10:15:31 +0000 Subject: KVM: MIPS: Implement VZ support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the main support for the MIPS Virtualization ASE (A.K.A. VZ) to MIPS KVM. The bulk of this work is in vz.c, with various new state and definitions elsewhere. Enough is implemented to be able to run on a minimal VZ core. Further patches will fill out support for guest features which are optional or can be disabled.
