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

From: [email-masked] (liudongdong (C))
Date: Tue, 26 Apr 2016 17:07:41 +0800

Based on the patchset and add the patch(Add ACPI support for HiSilicon PCIe Host Controllers).
Tested on the HiSilicon ARM64 D02 board.
it can work ok with Intel 82599 networking card.
This is the bootup log which contains PCIe host and Intel 82599 networking card part.

Tested-by: Dongdong Liu <[email-masked]>

? 2016/4/16 1:06, 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 at 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
