Initial ACPI support for ARM64 has been accepted into Linux kernel recently. Now it is a good time to re-visit ACPI support for KVM. This patchset enables ACPI for both arch_timer and vGIC by probing related ACPI tables and does necessary initialization. Note that Alexander Spyridaki submitted similar patches before. Some of his ideas were borrowed in this patchset, but with substancial changes. In addition we extend support for both GICv2 and GICv3. This patchset would work better on top of recent GIC/IRQCHIP patches by Hanjun Guo, who added support for gic_version in ACPI struct of GIC distributor (search "ACPICA: Introduce GIC version for arm based system"). This patchset can be applied cleanly on top of kvmarm.git queue branch. -Wei V1->V2: * Initialize vgic->max_gic_vcpus field in GICv2 code (found by Andrew Jones) * Rewrite arch_timer ACPI PPI parsing code * Verified patches on APM Mustang machine, which has arch_timer & GICv2 V1: * Initial patchset Wei Huang (5): kvm: arm64: Enable ACPI support for virt arch timer kvm: arm64: Dispatch virt GIC probing to device tree and ACPI kvm: arm64: Detect GIC version for proper ACPI vGIC probing kvm: arm64: Implement ACPI probing code for GICv2 kvm: arm64: Implement ACPI probing code for GICv3 include/kvm/arm_vgic.h | 36 +++++++++--- virt/kvm/arm/arch_timer.c | 75 ++++++++++++++++++++----- virt/kvm/arm/vgic-v2.c | 66 ++++++++++++++++++++-- virt/kvm/arm/vgic-v3.c | 56 +++++++++++++++++-- virt/kvm/arm/vgic.c | 140 ++++++++++++++++++++++++++++++++++++++++++---- 5 files changed, 332 insertions(+), 41 deletions(-) -- 1.8.3.1 -- 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
