Subject: [RFC PATCH 00/16] Refine PCI host bridge scan interfaces
Date: Mon, 17 Nov 2014 18:21:34 +0800 [thread overview]
Message-ID: <1416219710-26088-1-git-send-email-wangyijing@huawei.com> (raw)
This series is based Linux 3.18-rc1 and Lorenzo Pieralisi's
arm PCI domain cleanup patches, link:
https://patchwork.ozlabs.org/patch/407585/
Current pci scan interfaces like pci_scan_root_bus() and directly
call pci_create_root_bus()/pci_scan_child_bus() lack flexiblity.
Some platform infos like PCI domain and msi_chip have to be
associated to PCI bus by some arch specific function.
We want to make a generic pci_host_bridge, and make it hold
the platform infos or hook. Then we could eliminate the lots
of arch pci_domain_nr, also we could associate some platform
ops something like pci_get_msi_chip(struct pci_dev *dev)
with pci_host_bridge to avoid introduce arch weak functions.
This RFC version not for all platforms, just applied the new
scan interface in x86/arm/powerpc/ia64, I will refresh other
platforms after the core pci scan interfaces are ok.
Only test in x86.
Thanks!
Yijing.
Yijing Wang (16):
PCI: Enhance pci_scan_root_bus() to support default IO/MEM resources
PCI: Use pci_scan_root_bus() instead of pci_scan_bus()
PCI: Clean up pci_scan_bus()
PCI: Rip out pci_bus_add_devices() from pci_scan_root_bus()
PCI: Use pci_scan_root_bus() instead of pci_scan_bus_parented()
PCI: Use u32 type to combine PCI domain and bus number
PCI: Separate pci_host_bridge creation out of pci_create_root_bus()
PCI: Introduce pci_scan_host_bridge() and pci_host_info
PCI: Associate .get_msi_ctrl() with pci_host_bridge
PCI: Add of_scan_bus() to pci_host_info
x86/PCI: Use pci_scan_host_bridge() instead of pci_create_root_bus()
ia64/PCI: Remove the redundant bus variable
