From 3f010cf197324b6c1e87f472e64b87c5f909735e Mon Sep 17 00:00:00 2001 From: Tomasz Nowicki Date: Mon, 12 Sep 2016 20:32:25 +0200 Subject: irqchip/gicv3-its: Probe ITS in the ACPI way ITS is prepared for being initialized different than DT, therefore we can initialize it in ACPI way. We collect register base address from MADT table and pass mandatory info to firmware-agnostic ITS init call. Use here IORT lib to register ITS domain which then can be found and used on to build another PCI MSI domain in hierarchical stack domain. NOTE: Waiting for proper ITS and NUMA node relation description in IORT table, we pass around NUMA_NO_NODE to the its_probe_one init call. This means that Cavium ThunderX erratum 23144 (pass1.1 only) is not supported for ACPI boot method yet.
