Currently, KVM/ARM is limited to 4 A7 or A15 per VM. This is due to the fact that KVM doesn't know about clusters, and puts all CPUs at affinity level 0. This patch series removes this limitation by allowing additionnal CPUs to be part of a separate cluster (affinity level 1). This also requires a patch to kvmtool so the generated DT matches the expectations of the guest (posted separately). Tested on TC2 and arm64 model. Patches based on Christoffer's next tree as of today. Marc Zyngier (4): arm/arm64: KVM: PSCI: use MPIDR to identify a target CPU ARM: KVM: Fix MPIDR computing to support virtual clusters ARM: KVM: fix L2CTLR to be per-cluster ARM: KVM: drop limitation to 4 CPU VMs arch/arm/include/asm/kvm_emulate.h | 5 +++++ arch/arm/kvm/coproc.c | 14 ++++++++++---- arch/arm/kvm/psci.c | 17 +++++++++++++---- arch/arm/kvm/reset.c | 4 ---- arch/arm64/include/asm/kvm_emulate.h | 5 +++++ 5 files changed, 33 insertions(+), 12 deletions(-) -- 1.8.2.3 _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
