Hardly any change this time around, mostly rebased on top of upstream now that the dependencies have made it in. Tested with multiple concurrent VMs running from an initramfs. * From v2: - Rebased on 5.13-rc1 - Fixed a couple of nits in the GIC registration code * From v1 [1]: - Rebased on Hector's v4 posting[0] - Dropped a couple of patches that have been merged in the above series - Fixed irq_ack callback on the timer path [0] https://lore.kernel.org/r/20210402090542.131194-1-marcan@marcan.st [1] https://lore.kernel.org/r/20210316174617.173033-1-maz@kernel.org [2] https://lore.kernel.org/r/20210403112931.1043452-1-maz@kernel.org Marc Zyngier (9): irqchip/gic: Split vGIC probing information from the GIC code KVM: arm64: Handle physical FIQ as an IRQ while running a guest KVM: arm64: vgic: Be tolerant to the lack of maintenance interrupt KVM: arm64: vgic: Let an interrupt controller advertise lack of HW deactivation KVM: arm64: vgic: move irq->get_input_level into an ops structure KVM: arm64: vgic: Implement SW-driven deactivation KVM: arm64: timer: Refactor IRQ configuration KVM: arm64: timer: Add support for SW-based deactivation irqchip/apple-aic: Advertise some level of vGICv3 compatibility arch/arm64/kvm/arch_timer.c | 161 +++++++++++++++++++++---- arch/arm64/kvm/hyp/hyp-entry.S | 6 +- arch/arm64/kvm/vgic/vgic-init.c | 34 +++++- arch/arm64/kvm/vgic/vgic-v2.c | 19 ++- arch/arm64/kvm/vgic/vgic-v3.c | 19 ++- arch/arm64/kvm/vgic/vgic.c | 14 +-- drivers/irqchip/irq-apple-aic.c | 8 ++ drivers/irqchip/irq-gic-common.c | 13 -- drivers/irqchip/irq-gic-common.h | 2 - drivers/irqchip/irq-gic-v3.c | 6 +- drivers/irqchip/irq-gic.c | 6 +- include/kvm/arm_vgic.h | 41 +++++-- include/linux/irqchip/arm-gic-common.h | 25 +--- include/linux/irqchip/arm-vgic-info.h | 43 +++++++ 14 files changed, 291 insertions(+), 106 deletions(-) create mode 100644 include/linux/irqchip/arm-vgic-info.h -- 2.29.2
