Even though I haven't got the chance to test it on an GICv3 machine (will update later), I think you can add my name as Tested-by if needed. -Wei > > See the changes since v1 in the different patches. > > Regards, > > [1] https://lists.cs.columbia.edu/pipermail/kvmarm/2016-February/018482.html > [2] https://lists.cs.columbia.edu/pipermail/kvmarm/2016-February/018355.html > > Julien Grall (6): > KVM: arm/arm64: arch_timer: Gather KVM specific information in a > structure > KVM: arm/arm64: arch_timer: Rely on the arch timer to parse the > firmware tables > irqchip/gic-v2: Gather ACPI specific data in a single structure > irqchip/gic-v2: Parse and export virtual GIC information > irqchip/gic-v3: Parse and export virtual GIC information > KVM: arm/arm64: vgic: Rely on the GIC driver to parse the firmware > tables > > drivers/clocksource/arm_arch_timer.c | 11 ++-- > drivers/irqchip/irq-gic-common.c | 13 +++++ > drivers/irqchip/irq-gic-common.h | 3 ++ > drivers/irqchip/irq-gic-v3.c | 36 ++++++++++++++ > drivers/irqchip/irq-gic.c | 91 ++++++++++++++++++++++++++++++++-- > include/clocksource/arm_arch_timer.h | 13 ++--- > include/kvm/arm_vgic.h | 7 +-- > include/linux/irqchip/arm-gic-common.h | 34 +++++++++++++ > virt/kvm/arm/arch_timer.c | 39 ++++----------- > virt/kvm/arm/vgic-v2.c | 67 +++++++++---------------- > virt/kvm/arm/vgic-v3.c | 45 +++++------------ > virt/kvm/arm/vgic.c | 50 ++++++++++--------- > 12 files changed, 264 insertions(+), 145 deletions(-) > create mode 100644 include/linux/irqchip/arm-gic-common.h > -- 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
