irqchip/gic-v2: Parse and export virtual GIC information For now, the firmware tables are parsed 2 times: once in the GIC drivers, the other timer when initializing the vGIC. It means code duplication and make more tedious to add the support for another firmware table (like ACPI). Introduce a new structure and set of helpers to get/set the virtual GIC information. Also fill up the structure for GICv2. Signed-off-by: Julien Grall <julien.grall@arm.com> Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>

irqchip/gic: Split vGIC probing information from the GIC code The vGIC advertising code is unsurprisingly very much tied to the GIC implementations. However, we are about to extend the support to lesser implementations. Let's dissociate the vgic registration from the GIC code and move it into KVM, where it makes a bit more sense. This also allows us to mark the gic_kvm_info structures as __initdata. Reviewed-by: Alexandru Elisei <alexandru.elisei@arm.com> Signed-off-by: Marc Zyngier <maz@kernel.org>

irqchip/gic: Unify GIC priority definitions LPIs use the same priority value as other GIC interrupts. Make the GIC default priority definition visible to ITS implementation and use this same definition for LPI priorities.

irqchip/gic-v2m: Add support for Amazon Graviton variant of GICv3+GICv2m Add support for Amazon Graviton custom variant of GICv2m, where the message is encoded using the MSI message address, as opposed to standard GICv2m, where the SPI number is encoded in the MSI message data. In addition, the Graviton flavor of GICv2m is used along GICv3 (and not GICv2).
