Make MMCONFIG code arch-agnostic which allows all architectures to collect PCI config regions and used when necessary. 2. Move non-arch specific bits to the core code. 3. Use MMCONFIG code and implement generic ACPI based PCI host controller driver. 4. Enable above driver on ARM64 Patches has been built on top of 4.4 and can be found here: git@xxxxxxxxxx:semihalf-nowicki-tomasz/linux.git (pci-acpi-v3) NOTE, this patch set depends on Matthew's patches: http://www.spinics.net/lists/linux-pci/msg45950.html https://github.com/Vality/linux/tree/pci-fixes This has been tested on Cavium ThunderX server and QEMU. Any help in reviewing and testing is very appreciated. 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 4.4Tested this patch set (and Matthew's) on a HP RX2660 IA64 machine, with the CONFIG_ACPI_PCI_HOST_GENERIC disabled on IA64 ( it's a minor comment needs to be addressed in my previous email), it can boot the system ok with NIC working properly, with the /pro/ioports [1] and the boot log [2] if anyone needs refer to it. For this patch set, on IA64 machine, Tested-by: Hanjun Guo <hanjun.guo@xxxxxxxxxx>
I tested this patch set on x86 server with CONFIG_ACPI_PCI_HOST_GENERIC disabled today, also booted ok with NIC working properly.
