* [PATCH] PCI: fix race with pci_walk_bus and pci_destroy_devZhang Yanmin2006-06-21
| | | | | | | | | | | | | pci_walk_bus has a race with pci_destroy_dev. When cb is called in pci_walk_bus, pci_destroy_dev might unlink the dev pointed by next. Later on in the next loop, pointer next becomes NULL and cause kernel panic. Below patch against 2.6.17-rc4 fixes it by changing pci_bus_lock (spin_lock) to pci_bus_sem (rw_semaphore).

* [PATCH] PCI: Add pci_walk_bus function to PCI core (nonrecursive)Paul Mackerras2005-09-08
| | | | | | | | | | | | | | | | | | | | The PCI error recovery infrastructure needs to be able to contact all the drivers affected by a PCI error event, which may mean traversing all the devices under a given PCI-PCI bridge. This patch adds a function to the PCI core that traverses all the PCI devices on a PCI bus and under any PCI-PCI bridges on that bus (and so on), calling a given function for each device. This provides a way for the error recovery code to iterate through all devices that are affected by an error event. This version is not implemented as a recursive function. Instead, when we reach a PCI-PCI bridge, we set the pointers to start doing the devices on the bus under the bridge, and when we reach the end of a bus's devices, we use the bus->self pointer to go back up to the next higher bus and continue doing its devices.

* pci: make bus resource start address override minimum IO addressLinus Torvalds2005-08-02
| | | | | | | | | | | | | | The reason we have PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO is because we want to protect badly documented motherboard PCI resources and thus don't want to allocate new resources in low IO/MEM space. However, if we have already discovered a PCI bridge with a specified resource base, that should override that decision. This change will allow us to move the "careful" region upwards without resulting in problems allocating resources in low mappings. This was brought on by us having allocated a bus resource at 0x1000, conflicting with a undocumented VAIO Sony PI resources.
* [PATCH] acpi bridge hotadd: Link newly created pci child bus to its parent ↵Rajesh Shah2005-06-28
| | | | | | | | | | | | | | on creation When a pci child bus is created, add it to the parent's children list immediately rather than waiting till pci_bus_add_devices(). For hot-plug bridges/devices, pci_bus_add_devices() may be called much later, after they have been properly configured. In the meantime, this allows us to use the normal pci bus search functions for the hot-plug bridges/buses.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
