From 12ed1faece3f141c2604b5b3a8377ba71d23ec9d Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 13 Dec 2016 22:39:39 +0000 Subject: KVM: MIPS: Allow multiple VCPUs to be created MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Increase the maximum number of MIPS KVM VCPUs to 8, and implement the KVM_CAP_NR_VCPUS and KVM_CAP_MAX_CPUS capabilities which expose the recommended and maximum number of VCPUs to userland. The previous maximum of 1 didn't allow for any form of SMP guests. We calculate the values similarly to ARM, recommending as many VCPUs as there are CPUs online in the system. This will allow userland to know how many VCPUs it is possible to create.
