From 0c9f302ea2906eb763cd175134e34d23ed4fea6a Mon Sep 17 00:00:00 2001 From: Pavel Fedin Date: Tue, 4 Oct 2016 13:28:09 +0100 Subject: hw/intc/arm_gicv3_its: Implement support for in-kernel ITS emulation The ITS control frame is in-kernel emulated while accesses to the GITS_TRANSLATER are mediated through the KVM_SIGNAL_MSI ioctl (MSI direct MSI injection advertised by the CAP_SIGNAL_MSI capability) the kvm_gsi_direct_mapping is explicitly set to false to emphasize the difference with GICv2M. Direct mapping cannot work with ITS since the content of the MSI data is not the target interrupt ID but an eventd id. GSI routing is advertised (kvm_gsi_routing_allowed) as well as msi/irqfd signaling (kvm_msi_via_irqfd_allowed). The MSI frame (GITS_TRANSLATER) absolute GPA is computed on first kvm_its_send_msi() call. It is then passed through KVM_SIGNAL_MSI ioctl.
