class ArmDevicetreeGicItem

Defined at line 202 of file ../../zircon/kernel/phys/lib/boot-shim/include/lib/boot-shim/devicetree.h

Parses either GIC v2 or GIC v3 device node into proper ZBI item.

This item will scan the devicetree for either a node compatible with GIC v2 bindings or GIC v3

bindings. Upon finding such node it will generate either a |zbi_dcfg_arm_gic_v2_driver_t| for

GIC v2 or a |zbi_dcfg_arm_gic_v3_driver_t| for GIC v3.

In case of GIC v2, it will determine whether the MSI extension is supported or not by looking

at the children of the GIC v2 node.

Each interrupt controller contains uses a custom format for their 'reg' property, which defines

the different address ranges required for the driver.

See for GIC v2:

See for GIC v3:
