Subject: [PATCH v7 00/31] Refine PCI scan interfaces and make generic pci host bridge
Date: Mon, 23 Mar 2015 20:40:26 +0800 [thread overview]
Message-ID: <1427114457-16687-1-git-send-email-wangyijing__23338.7319990017$1427114946$gmane$org@huawei.com> (raw)
v6->v7:
Drop previous patch which combined the domain and bus in one argument.
Make the pci_host_bridge hold the default busn resource, so we could
check whether new host busn resource is conflict with existing ones.
Move pci_host_assign_domain_nr() to drivers/pci/host-bridge.c
Other changes suggested by Bjorn and Suravee.
v5->v6:
Fix cross building errors found by kbuild test.
Export busn_resource to Xen pcifront driver.
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/enumeration branch.
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_host_bridge()
for callers provide its own parent and io/mem/bus resources
Arnd Bergmann (1):
