This is a new version of the series previously posted at [2], reworking the vGIC and timer code to cope with the M1 braindead^Wamusing nature. 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@xxxxxxxxx [1] https://lore.kernel.org/r/20210316174617.173033-1-maz@xxxxxxxxxx [2] https://lore.kernel.org/r/20210403112931.1043452-1-maz@xxxxxxxxxx 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
