The series builds the PCI/MSI domain stack based on initial IORT driver which is added in first place. As a reference please see IORT spec: http://infocenter.arm.com/help/topic/com.arm.doc.den0049b/DEN0049B_IO_Remapping_Table.pdf Patches were built on top of accepted ARM64 ACPI PCI support and can be found all together here: https://github.com/semihalf-nowicki-tomasz/linux.git (its-acpi-v6) Tested on Cavium ThunderX server. v5 -> v6 - added locking mechanism for IORT list with domain token - IORT function name improvements - extended IORT RID mapping helper - reworked IORT to be more SMMU friendly - IORT functions which map RID and find corresponding domain are not PCI specific any more (struct pci_dev -> struct device) - bug fixes v4 -> v5 - rebased against v4.7-rc1 - drop generic layer and call IORT functions directly - improve resource abstraction and string formatting v3 -> v4 - rebased against v4.5 - add ACPI support for IRQ domain handling on a per-device basis - reorder domain setup step - improve error handling - code style improvements v2 -> v3 - rebased on top of 4.4 - fixes and improvements for redistributor init via GICC structures - fixes as per kbuild reports v1 -> v2 - rebased on top of 4.4-rc4 - use pci_msi_domain_get_msi_rid for requester ID to device ID translation Tomasz Nowicki (7): ACPI: I/O Remapping Table (IORT) initial support PCI/MSI: Setup MSI domain on a per-devices basis using IORT ACPI table irqchip/gicv3-its: Cleanup for ITS domain initialization irqchip/gicv3-its: Refator ITS DT init code to prepare for ACPI irqchip/gicv3-its: Probe ITS in the ACPI way irqchip/gicv3-its: Factor out code that might be reused for ACPI irqchip/gicv3-its: Use MADT ITS subtable to do PCI/MSI domain initialization drivers/acpi/Kconfig | 3 + drivers/acpi/Makefile | 1 + drivers/acpi/iort.c | 386 +++++++++++++++++++++++++++++++ drivers/irqchip/Kconfig | 1 + drivers/irqchip/irq-gic-v3-its-pci-msi.c | 88 +++++-- drivers/irqchip/irq-gic-v3-its.c | 185 ++++++++++----- drivers/irqchip/irq-gic-v3.c | 7 +- drivers/pci/msi.c | 11 +- include/linux/iort.h | 38 +++ include/linux/irqchip/arm-gic-v3.h | 4 +- 10 files changed, 646 insertions(+), 78 deletions(-) create mode 100644 drivers/acpi/iort.c create mode 100644 include/linux/iort.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
