This is an implementation of the Power State Coordination Interface, as described there (registration required): http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.den0022a/index.html It allows CPUs to be powered on, off, suspended or migrated. This series is only concerned with power-{on,off}. KVM Tool uses it to boot SMP VMs. This is also supported by the mach-virt platform: git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git virt/mach Tested on the arm64 model, based on kvm-arm-master as of today. >From v1: - Documentation - Move the one-time init to a separate function - "One mask fits all" - Use wait_event_interruptible instead of the open coded version Marc Zyngier (2): ARM: KVM: move one-time init to its own function ARM: KVM: Power State Coordination Interface implementation Documentation/virtual/kvm/api.txt | 4 ++ arch/arm/include/asm/kvm_emulate.h | 5 +++ arch/arm/include/asm/kvm_host.h | 5 ++- arch/arm/include/asm/kvm_psci.h | 23 ++++++++++ arch/arm/include/uapi/asm/kvm.h | 16 +++++++ arch/arm/kvm/Makefile | 2 +- arch/arm/kvm/arm.c | 59 +++++++++++++++++-------- arch/arm/kvm/psci.c | 90 ++++++++++++++++++++++++++++++++++++++ include/uapi/linux/kvm.h | 1 + 9 files changed, 184 insertions(+), 21 deletions(-) create mode 100644 arch/arm/include/asm/kvm_psci.h create mode 100644 arch/arm/kvm/psci.c -- 1.8.1 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
