| | | | | | | | | | I don't have this hardware but it looks like we weren't adding bridge devices as intended. Maybe the bridge is always the last device?

* | PCI: Remove unnecessary __ref annotationsBjorn Helgaas2014-04-291-1/+1
|/ | | | | | | | | | | | | | | | Some PCI functions used to be marked __devinit. When CONFIG_HOTPLUG was not set, these functions were discarded after boot. A few callers of these __devinit functions were marked __ref to indicate that they could safely call the __devinit functions even though the callers were not __devinit. But CONFIG_HOTPLUG and __devinit are now gone, and the need for the __ref annotations is also gone, so remove them.

* PCI: cpcihp: Iterate over all devices in slot, not functions 0-7Yijing Wang2013-01-251-18/+11
| | | | | | | | | | | | | | Iterate through devices in a slot by using the upstream bridge's "bus->devices" list instead of assuming they are functions 0-7. It's possible there are several slots on the same pci_bus, so restrict it to only devices matching this slot's device number. ARI (which allows functions 0-255) is a PCIe-only feature, and this is a PCI hotplug driver, so we shouldn't find anything other than functions 0-7, but it's better to iterate the same way as other hotplug drivers.

Now, we simply advise the PCI core of the name that we would like, and let the core take care of the rest.

* [PATCH] CPCI hotplug: fix resource assignmentScott Murray2006-08-261-12/+42
| | | | | | | | | | | | | | Here is a patch against the CPCI hotplug core to fix up PCI resource assignment such that things will actually work when a hot inserted device is enabled. I mentioned this patch to you way back in April at ELC, but am only now out from under things enough to clean it up and submit it. I've basically cribbed the corresponding code from shpchp_pci.c, so there are no big surprises. If it's still possible, I wouldn't mind this going into 2.6.18, but it wouldn't be the end of the world if it went into 2.6.19.

* [PATCH] PCI Hotplug: more CPCI updatesScott Murray2005-05-311-90/+54
| | | | | | | | | | | | | | | | | | | | | | | | | Here is my third attempt at a patch to further update the CompactPCI hotplug driver infrastructure to address the pci_enable_device issue discussed on the list as well as a few other issues I discovered during some more testing. This version addresses a few more issues pointed out by Prarit Bhargava. Changes include: - cpci_enable_device and its recursive calling of pci_enable_device on new devices removed. - Use list_rwsem to avoid slot status change races between disable_slot and check_slots. - Fixed oopsing in cpci_hp_unregister_bus caused by calling list_del on a slot after calling pci_hp_deregister. - Removed kfree calls in cleanup_slots since release_slot will have done it already. - Reworked init_slots a bit to fix latch and adapter file updating on subsequent calls to cpci_hp_start. - Improved sanity checking in cpci_hp_register_controller. - Now shut things down correctly in cpci_hotplug_exit. - Switch to pci_get_slot instead of deprecated pci_find_slot. - A bunch of CodingStyle fixes.

* [PATCH] PCI Hotplug: CPCI updateScott Murray2005-05-171-327/+25
| | | | | | | | | | | | | | | | | | | | | | [PATCH] CPCI: update I have finally done some work to update the CompactPCI hotplug driver to fix some of the outstanding issues in 2.6: - Added adapter and latch status ops so that those files will get created by the current PCI hotplug core. This used to not be required, but seems to be now after some of the sysfs rework in the core. - Replaced slot list spinlock with a r/w semaphore to avoid any potential issues with sleeping. This quiets all of the runtime warnings. - Reworked interrupt driven hot extraction handling to remove need for a polling operator for ENUM# status. There are a lot of boards that only have an interrupt driven by ENUM#, so this lowers the bar to entry. - Replaced pci_visit_dev usage with better use of the PCI core functions. The new code is functionally equivalent to the previous code, but the use of pci_enable_device on insert needs to be investigated further, as I need to do some more testing to see if it is still necessary.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+661
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!
