kvm_set_routing_entry is changing in -next, and causes things to explode. Add a temporary workaround that should be dropped when we hit 4.8-rc1 Signed-off-by: NMarc Zyngier <marc.zyngier@arm.com>

Up to now, only irqchip routing entries could be set. This patch adds the capability to insert MSI routing entries. For ARM64, let's also increase KVM_MAX_IRQ_ROUTES to 4096: this include SPI irqchip routes plus MSI routes. In the future this might be extended.

This patch adds compilation and link against irqchip. Main motivation behind using irqchip code is to enable MSI routing code. In the future irqchip routing may also be useful when targeting multiple irqchips. Routing standard callbacks now are implemented in vgic-irqfd: - kvm_set_routing_entry - kvm_set_irq - kvm_set_msi They only are supported with new_vgic code. Both HAVE_KVM_IRQCHIP and HAVE_KVM_IRQ_ROUTING are defined. KVM_CAP_IRQ_ROUTING is advertised and KVM_SET_GSI_ROUTING is allowed. So from now on IRQCHIP routing is enabled and a routing table entry must exist for irqfd injection to succeed for a given SPI. This patch builds a default flat irqchip routing table (gsi=irqchip.pin) covering all the VGIC SPI indexes. This routing table is overwritten by the first first user-space call to KVM_SET_GSI_ROUTING ioctl. MSI routing setup is not yet allowed.

Connect to the new VGIC to the irqfd framework, so that we can inject IRQs. GSI routing and MSI routing is not yet implemented. Signed-off-by: NAndre Przywara <andre.przywara@arm.com> Reviewed-by: NChristoffer Dall <christoffer.dall@linaro.org>
