[PATCH V6 00/13] Support for generic ACPI based PCI host controller

by Tomasz Nowicki

>From the functionality point of view this series might be split into the following logic parts: 1. Necessary fixes as the preparation for using driver on ARM64. 2. New ECAM API and update for users of the pci-host-common API 3. Use new MCFG interface and implement generic ACPI based PCI host controller driver. 4. Enable above driver on ARM64 Patches has been built on top of 4.6-rc2 and can be found here: git@github.com:semihalf-nowicki-tomasz/linux.git (pci-acpi-v6) This has been tested on Cavium ThunderX server. Any help in reviewing and testing is very appreciated. v5 -> v6 - dropped idea of x86 MMCONFIG code refactoring - integrated JC's patches which introduce new ECAM API: https://lkml.org/lkml/2016/4/11/907 git: https://github.com/jchandra-brcm/linux/ (arm64-acpi-pci-v3) - integrated Sinan's fix for releasing IO resources, see patch [06/13] - added ACPI support for ThunderX ECAM and PEM drivers - rebased to 4.6-rc2 v4 -> v5 - dropped MCFG refactoring group patches 1-6 from series v4 and integrated Jayachandran's patch https://patchwork.ozlabs.org/patch/575525/ - rewrite PCI legacy IRQs allocation - squashed two patches 11 and 12 from series v4, fixed bisection issue - changelog improvements - rebased to 4.5-rc3 v3 -> v4 - dropped Jiang's fix http://lkml.iu.edu/hypermail/linux/kernel/1601.1/04318.html - added Lorenzo's fix patch 19/24 - ACPI PCI bus domain number assigning cleanup - changed resource management, we now claim and reassign resources - improvements for applying quirks - dropped Matthew's http://www.spinics.net/lists/linux-pci/msg45950.html dependency - rebased to 4.5-rc1 v2 -> v3 - fix legacy IRQ assigning and IO ports registration - remove reference to arch specific companion device for ia64 - move ACPI PCI host controller driver to pci_root.c - drop generic domain assignment for x86 and ia64 as I am not able to run all necessary test variants - drop patch which cleaned legacy IRQ assignment since it belongs to Mathew's series: https://patchwork.ozlabs.org/patch/557504/ - extend MCFG quirk code - rebased to 4.4 v1 -> v2 - moved non-arch specific piece of code to dirver/acpi/ directory - fixed IO resource handling - introduced PCI config accessors quirks matching - moved ACPI_COMPANION_SET to generic code v1 - https://lkml.org/lkml/2015/10/27/504 v2 - https://lkml.org/lkml/2015/12/16/246 v3 - http://lkml.iu.edu/hypermail/linux/kernel/1601.1/04308.html v4 - https://lkml.org/lkml/2016/2/4/646 v5 - https://lkml.org/lkml/2016/2/16/426 Jayachandran C (2): PCI: Provide common functions for ECAM mapping PCI: generic, thunder: update to use generic ECAM API Tomasz Nowicki (11): pci, acpi, x86, ia64: Move ACPI host bridge device companion assignment to core code. pci, acpi: Provide generic way to assign bus domain number. x86, ia64: Include acpi_pci_{add|remove}_bus to the default pcibios_{add|remove}_bus implementation. pci, of: Move the PCI I/O space management to PCI core code. acpi, pci: Support IO resources when parsing PCI host bridge resources. arm64, pci, acpi: ACPI support for legacy IRQs parsing and consolidation with DT code. pci, acpi: Support for ACPI based generic PCI host controller arm64, pci, acpi: Start using ACPI based PCI host controller driver for ARM64. pci, acpi: Match PCI config space accessors against platfrom specific quirks. pci, pci-thunder-ecam: Add ACPI support for ThunderX ECAM. pci, pci-thunder-pem: Add ACPI support for ThunderX PEM. arch/arm64/Kconfig | 15 +++ arch/arm64/include/asm/cpufeature.h | 3 +- arch/arm64/kernel/cpu_errata.c | 8 ++ arch/arm64/kernel/pci.c | 35 ++--- arch/ia64/hp/common/sba_iommu.c | 2 +- arch/ia64/include/asm/pci.h | 1 - arch/ia64/pci/pci.c | 26 ---- arch/ia64/sn/kernel/io_acpi_init.c | 4 +- arch/x86/include/asm/pci.h | 3 - arch/x86/pci/acpi.c | 17 --- arch/x86/pci/common.c | 10 -- drivers/acpi/Kconfig | 8 ++ drivers/acpi/Makefile | 1 + drivers/acpi/bus.c | 1 + drivers/acpi/pci_gen_host.c | 259 ++++++++++++++++++++++++++++++++++++ drivers/acpi/pci_root.c | 58 +++++++- drivers/of/address.c | 116 +--------------- drivers/pci/Kconfig | 3 + drivers/pci/Makefile | 2 + drivers/pci/ecam.c | 137 +++++++++++++++++++ drivers/pci/ecam.h | 66 +++++++++ drivers/pci/host/Kconfig | 1 + drivers/pci/host/pci-host-common.c | 119 ++++++++--------- drivers/pci/host/pci-host-common.h | 47 ------- drivers/pci/host/pci-host-generic.c | 52 ++------ drivers/pci/host/pci-thunder-ecam.c | 70 ++++++---- drivers/pci/host/pci-thunder-pem.c | 215 ++++++++++++++++++++++-------- drivers/pci/pci.c | 150 ++++++++++++++++++++- drivers/pci/probe.c | 5 + include/asm-generic/vmlinux.lds.h | 7 + include/linux/of_address.h | 9 -- include/linux/pci-acpi.h | 20 +++ include/linux/pci.h | 12 ++ 33 files changed, 1029 insertions(+), 453 deletions(-) create mode 100644 drivers/acpi/pci_gen_host.c create mode 100644 drivers/pci/ecam.c create mode 100644 drivers/pci/ecam.h delete mode 100644 drivers/pci/host/pci-host-common.h -- 1.9.1
