ARM64, ACPI, PCI: I/O Remapping Table (IORT) initial support. irqchip, gicv3, its: Probe ITS in the ACPI way. acpi, gicv3, msi: Factor out code that might be reused for ACPI equivalent. acpi, gicv3, its: Use MADT ITS subtable to do PCI/MSI domain initialization. drivers/acpi/Kconfig | 3 + drivers/acpi/Makefile | 1 + drivers/acpi/iort.c | 326 +++++++++++++++++++++++++++++ drivers/irqchip/Kconfig | 1 + drivers/irqchip/irq-gic-v3-its-pci-msi.c | 85 ++++++-- drivers/irqchip/irq-gic-v3-its.c | 143 +++++++++---- drivers/irqchip/irq-gic-v3.c | 344 ++++++++++++++++++++++++++----- drivers/pci/msi.c | 3 + include/linux/iort.h | 38 ++++ include/linux/irqchip/arm-gic-v3.h | 2 +- 10 files changed, 845 insertions(+), 101 deletions(-) create mode 100644 drivers/acpi/iort.c create mode 100644 include/linux/iort.h -- 1.9.1
