* [PATCH] shpchp: remove redundant data structuresrajesh.shah@intel.com2005-10-28
| | | | | | | | | | | | | State information is currently stored in per-slot as well as per-pci-function data structures in shpchp. There's a lot of overlap in the information kept, and some of it is never used. This patch consolidates the state information to per-slot and eliminates unused data structures. The biggest change is to eliminate the pci_func structure and the code around managing its lists. Signed-off-by: Rajesh Shah <rajesh.shah@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] shpchp: detect SHPC capability before doing a lot of workrajesh.shah@intel.com2005-10-28
| | | | | | | | | | | | | The shpc driver registers its probe function for all pci-pci bridges in the system. Not all of them will be shpc capable, so look for this capability early in the probe function and return if there's no work to do on this bridge. The old shpc driver did some initialization work on all bridges before detecting that shpc is not supported and unwinds the work it's already done in that case.

* [PATCH] shpchp: reduce dependence on ACPIrajesh.shah@intel.com2005-10-28
| | | | | | | | | | | | | | | | | | | Reduce the SHPC hotplug driver's dependence on ACPI. We don't walk the acpi namespace anymore to build a list of bridges and devices. The remaining interaction with ACPI is to run the _OSHP method to transition control of hotplug hardware from system BIOS to the shpc hotplug driver, and to run the _HPP method to get hotplug device parameters like cache line size, latency timer and SERR/PERR enable from BIOS. Note that one of the side effects of this patch is that shpchp does not enable the hot-added device or its DMA bus mastering automatically now. It expects the device driver to do that. This may break some drivers and we will have to fix them as they are reported. Signed-off-by: Rajesh Shah <rajesh.shah@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] ppc64 PCI Hotplug: cleanup unsymmetric API routineslinas2005-10-28
| | | | | | | | | | | | | | | | | This is a minor patch to the ppc64 PCI hotplug code; it makes the call to rpaphp_unconfig_pci_adapter() symmetric with respect to the call to rpaphp_config_pci_adapter(). I discussed this with John Rose, who had provided the last round of changes for these functions; he appearently had this patch but somehow failed to mail it out. Tested. (added/removed device).

* [PATCH] PCI Hotplug: rpaphp: Purify hotplugJohn Rose2005-09-08
| | | | | | | | | | | | | | | | | | Currently rpaphp registers the following bus types as hotplug slots: 1) Actual PCI Hotplug slots 2) Embedded/Internal PCI slots 3) PCI Host Bridges The second and third bus types are not actually direct parents of removable adapters. As such, the rpaphp has special case code to fake results for attributes like power, adapter status, etc. This patch removes types 2 and 3 from the rpaphp module. This patch also changes the DLPAR module so that slots can be DLPAR-added/removed without having been designated as hotplug-capable.

* [PATCH] PCI Hotplug: rpaphp: Change slot pci referenceJohn Rose2005-09-08
| | | | | | | | | | | | | | | | The slot structure in the rpaphp module currently references the PCI contents of the slot using the PCI device of the parent bridge. This is unnecessary, since the module is actually interested in the subordinate bus of the bridge. The dependency on a PCI bridge device also prohibits the module from registering hotplug slots that have a root bridge as a parent, since root bridges on PPC64 don't have PCI devices. This patch changes struct slot to reference the PCI subsystem using a pci_bus rather than a pci_dev.

* [PATCH] PCI Hotplug: rpaphp: Move VIO registrationJohn Rose2005-09-08
| | | | | | | | | | | | | | | | Currently, rpaphp registers Virtual I/O slots as hotplug slots. The only purpose of this registration is to ensure that the VIO subsystem is notified of new VIO buses during DLPAR adds. Similarly, rpaphp notifies the VIO subsystem when a VIO bus is DLPAR-removed. The rpaphp module has special case code to fake results for attributes like power, adapter status, etc. The VIO register/unregister functions could just as easily be made from the DLPAR module. This patch moves the VIO registration calls to the DLPAR module, and removes the VIO fluff from rpaphp altogether.

| | | | | | | | | | | | | | | | | | | | | | [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.
