From cf1fb0f29d83bcc1d8af912e56f2295397372908 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Wed, 15 Jun 2016 19:29:55 +0100 Subject: MIPS: KVM: Emulate RDHWR CPUNum register MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Actually provide the VCPU number when emulating the RDHWR CPUNum register, so that it will match the CPUNum field of CP0_EBase register, rather than always returning 0.
