Subject: [PATCH v5 00/29] Refine PCI scan interfaces and make generic pci host bridge
Date: Fri, 6 Mar 2015 17:33:17 +0800 [thread overview]
Message-ID: <1425634426-437-1-git-send-email-wangyijing@huawei.com> (raw)
v4-v5:
Fix some code style issues and rename some functions suggested by Bjorn.
Fix some code flaw(Eg. call pci_bus_add_devices() before resources claim
or lack the return checking).
v3->v4:
Fix the rebase issue.
v2->v3:
Rebase this series on v4.0-rc1.
v1->v2:
Split pci_host_bridge_list into a new patch, remove .phb_probe_mode
and rework powerpc .phb_of_scan_bus() for simpilicty suggested by
Arnd. Refresh some patch description log, and add a new patch to fix
build warning in ia64.
This series is based on Bjorn's pci-next branch.
Patch 1-4 ripped out pci_bus_add_devices() from pci scan interfaces
for better pci scan flow.
Patch 5-11 make a generic pci_host_bridge to hold pci_host_bridge
related informations, and introduce a pci_host_bridge_ops to
support platform host drivers provide its own pci_host_bridge
related operations to setup pci_host_bridge during pci enumeration.
Patch 12-28 apply the new pci scan interfaces to platform pci host
bridge drivers.
Now in kernel, we scan pci bus use the following ways:
1. pci_scan_bus.
parent = NULL, default io/mem/bus resources
call pci_bus_add_devices()
2. pci_scan_bus_parented() + pci_bus_add_devices()
default io/mem/bus resources, only used by xen
3. pci_scan_root_bus() + pci_bus_add_devices()
4. pci_create_root_bus() + pci_scan_child_bus() + pci_bus_add_devices()
5. pci_create_root_bus() + xx_of_scan_bus() + pci_bus_add_devices()
And we have a lot of arch specific pci_domain_nr() and other platform
specific weak function like pcibios_root_bridge_prepare().
After applied this series, we have following scan interfaces:
1. pci_scan_bus()
parent = NULL, default io/mem/bus resources.
for legacy pci scan
2. pci_scan_root_bus()
for callers provide its own parent and io/mem/bus resources
but no platform specific pci_host_bridge operations
3. pci_scan_root_bridge()
for callers provide its own parent and io/mem/bus resources
