2017-01-20hw/intc/arm_gicv3: Implement EL2 traps for CPU i/f regsPeter Maydell1-10/+60
Implement the architecturally required traps from NS EL1 to EL2 for the CPU interface registers. These fall into several different groups: * group-0-only registers all trap if ICH_HRC_EL2.TALL0 is set (exactly the registers covered by gicv3_fiq_access()) * group-1-only registers all trap if ICH_HRC_EL2.TALL1 is set (exactly the registers covered by gicv3_irq_access()) * DIR traps if ICH_HCR_EL2.TC or ICH_HCR_EL2.TDIR are set * PMR, RPR, CTLR trap if ICH_HCR_EL2.TC is set * SGI0R, SGI1R, ASGI1R trap if ICH_HCR_EL2.TC is set or if HCR_EL2.IMO or HCR_EL2.FMO are set We split DIR and the SGI registers out into their own access functions, leaving the existing gicv3_irqfiq_access() just handling PMR, RPR and CTLR. This commit doesn't implement support for trapping on HSTR_EL2.T12 for the 32-bit registers, as we don't implement any of those per-coprocessor trap bits currently and probably will want to do those in some more centralized way.

Augment the GIC's QOM device interface by adding two new sets of sysbus IRQ lines, to signal VIRQ and VFIQ to each CPU. We never use these, but it's helpful to keep the v2-and-earlier GIC's external interface in line with that of the GICv3 to avoid board code having to add extra code conditional on which version of the GIC is in use.

2017-01-16x86: ioapic: fix fail migration when irqchip=splitPeter Xu1-0/+5
Split irqchip works based on the fact that we kept the first 24 gsi routing entries inside KVM for userspace ioapic's use. When system boot, we'll reserve these MSI routing entries before hand. However, after migration, we forgot to re-configure it up in the destination side. The result is, we'll get invalid gsi routing entries after migration (all empty), and we get interrupts with vector=0, then strange things happen, like keyboard hang. The solution is simple - we update them after migration, which is a one line fix.

2016-12-27hw/intc/arm_gicv3: Don't signal Pending+Active interrupts to CPUPeter Maydell1-0/+5
The GICv3 requires that we only signal Pending interrupts to the CPU. This category does not include Pending+Active interrupts, which means we need to check whether the interrupt is Active in the gicr_int_pending() and gicd_int_pending() functions. Interrupts are rarely in the Active+Pending state, but KVM uses this as part of its handling of the virtual timer, so this bug was causing KVM to go into an infinite loop of taking the vtimer interrupt when the guest first triggered it.

2016-12-27hw/intc/arm_gicv3: Remove incorrect usage of fieldoffsetPeter Maydell1-7/+6
In the ARMCPRegInfo definitions for the GICv3 CPU interface registers, we were trying to use .fieldoffset to specify the locations of data fields within the GICv3CPUState struct. This is completely broken, because .fieldoffset is for offsets into the CPUARMState struct. We didn't notice because we were only using this for reads to BPR0, AP0R<n>, IGRPEN0 and CTLR_EL3, and Linux doesn't use these registers. Replace the .fieldoffset uses with explicit read functions.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth1-1/+1
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-10-17apic: add send_msi() to APICCommonClassRadim Krčmář1-2/+6
The MMIO based interface to APIC doesn't work well with MSIs that have upper address bits set (remapped x2APIC MSIs). A specialized interface is a quick and dirty way to avoid the shortcoming.

2016-10-17apic: add global apic_get_class()Radim Krčmář1-0/+1
Every configuration has only up to one APIC class and we'll be extending the class with a function that can be called without an instanced object, so a direct access to the class is convenient. This patch will break compilation if some code uses apic_get_class() with CONFIG_USER_ONLY.

2016-10-14ppc/xics: Split ICS into ics-base and ics classBenjamin Herrenschmidt4-81/+121
The existing implementation remains same and ics-base is introduced. The type name "ics" is retained, and all the related functions renamed as ics_simple_* This will allow different implementations for the source controllers such as the MSI support of PHB3 on Power8 which uses in-memory state tables for example.

2016-10-14ppc/xics: Make the ICSState a listBenjamin Herrenschmidt4-75/+128
Instead of an array of fixed sized blocks, use a list, as we will need to have sources with variable number of interrupts. SPAPR only uses a single entry. Native will create more. If performance becomes an issue we can add some hashed lookup but for now this will do fine.

2016-10-04hw/intc/arm_gicv3_its: Implement support for in-kernel ITS emulationPavel Fedin2-0/+122
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.

2016-10-04hw/intc/arm_gic(v3)_kvm: Initialize gsi routingEric Auger2-0/+25
Advertise gsi routing and set up irqchip routing entries for GIC SPIs. This is not mandated as long as MSI routing is not used (because the kernel sets a default irqchip routing table). However once MSI routing gets used (for VIRTIO-PCI vhost for example), the first call to KVM_SET_GSI_ROUTING overrides the kernel default irqchip table. If no routing entry exists for the GSI, any IRQFD signaling for this GSI will fail.
