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 Tested on Cavium ThunderX server and Qualcomm Technologies server platform QDF2XXX. The patches can be found here: https://github.com/semihalf-nowicki-tomasz/linux.git (its-acpi-v11) v10 -> v11 - rebased against v4.8-rc6 - bug fix for iort_match_node_callback() error handling - patch 1-2 changelog updates v9 -> v10 - error handling improvements for iort_match_node_callback() but no functional changes - iort.h -> acpi_iort.h header name change - style improvements v8 -> v9 - rebased against v4.8-rc4 - move root IORT pointer validation to one place iort_scan_node() - function names & Kconfig option name improvements - remove annoying dev_err() appearances for non-IORT users - for debug purpose print full ITS resource range v7 -> v8 - rebased against v4.8-rc1 - move IORT support under new drivers/acpi/arm64 directory - memory leak fix for iort_match_node_callback() - iort_node_map_rid() algorithm improvements - fix RID match check in iort_id_map() - fix typos and white spaces v6 -> v7 - rebased against irq/irqchip-4.8 - improvements for IORT ID mapping - call IORT init call from acpi_init() instead of arch_initcall() - split IORT driver in to two parts: core and ITS/MSI 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 (8): ACPI: I/O Remapping Table (IORT) initial support ACPI: Add new IORT functions to support MSI domain handling PCI/MSI: Setup MSI domain on a per-device basis using IORT ACPI table irqchip/gicv3-its: Cleanup for ITS domain initialization irqchip/gicv3-its: Refactor ITS DT init code to prepare for ACPI irqchip/gicv3-its: Probe ITS in the ACPI way irqchip/gicv3-its: Factor out PCI-MSI part that might be reused for ACPI irqchip/gicv3-its: Use MADT ITS subtable to do PCI/MSI domain initialization drivers/acpi/Kconfig | 4 + drivers/acpi/Makefile | 2 + drivers/acpi/arm64/Kconfig | 6 + drivers/acpi/arm64/Makefile | 1 + drivers/acpi/arm64/iort.c | 366 +++++++++++++++++++++++++++++++ drivers/acpi/bus.c | 2 + drivers/irqchip/Kconfig | 1 + drivers/irqchip/irq-gic-v3-its-pci-msi.c | 88 ++++++-- drivers/irqchip/irq-gic-v3-its.c | 171 +++++++++++---- drivers/irqchip/irq-gic-v3.c | 7 +- drivers/pci/msi.c | 11 +- include/linux/acpi_iort.h | 42 ++++ include/linux/irqchip/arm-gic-v3.h | 4 +- 13 files changed, 635 insertions(+), 70 deletions(-) create mode 100644 drivers/acpi/arm64/Kconfig create mode 100644 drivers/acpi/arm64/Makefile create mode 100644 drivers/acpi/arm64/iort.c create mode 100644 include/linux/acpi_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
