Peter Maydell d87576e38d arm_gicv3: Fix broken logic in ELRSR calculation
Fix a broken expression in the calculation of ELRSR
register bits: instead of "(lr & ICH_LR_EL2_HW) == 1"
we want to check for != 0, because the HW bit is not
bit 0 so a test for == 1 is always false.

Michael Davidsaver d713ea6c46 armv7m_nvic: keep a pointer to the CPU
Many NVIC operations access the CPU state, so store a pointer in
struct nvic_state rather than fetching it via qemu_get_cpu() every
time we need it.

As with the arm_gicv3_common code, we currently just call
qemu_get_cpu() in the NVIC's realize method, but in future we might
want to use a QOM property to pass the CPU to the NVIC.

This imposes an ordering requirement that the CPU is
realized before the NVIC, but that is always true since
both are dealt with in armv7m_init().

Peter Maydell 86830554db hw/intc/arm_gicv3: Implement EL2 traps for CPU i/f regs
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.

 * add the necessary data fields to the state structures
 * add the fields to the migration state, as a subsection

The use of a subsection means we retain migration
compatibility as EL2 is not enabled on any CPUs currently.

Peter Maydell 6a22895908 hw/intc/arm_gic: Add external IRQ lines for VIRQ and VFIQ
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.

Peter Xu 0f254b1ae0 x86: ioapic: fix fail migration when irqchip=split
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.

Peter Maydell 0bfa02595a hw/intc/arm_gicv3: Don't signal Pending+Active interrupts to CPU
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.

Peter Maydell e971fa0422 hw/intc/arm_gicv3: Remove incorrect usage of fieldoffset
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.

Thomas Huth fcf5ef2ab5 Move target-* CPU file into a target/ folder
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.

Pavel Fedin 0c9f302ea2 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.
