* [PATCH] USB: UHCI: Split apart the physical and logical framelist arraysAlan Stern2005-10-28
| | | | | | | | | | | This patch (as563) splits the physical and logical framelist arrays in uhci-hcd into two separate pieces. This will allow slightly better memory utilization, since each piece is no larger than a single page whereas before the whole thing was a little bigger than two pages. It also allows the logical array to be allocated in non-DMA-coherent memory. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] USB: UHCI: Remove unused fields and unneeded tests for NULLAlan Stern2005-10-28
| | | | | | | | | | | | | This patch (as562) removes from the uhci-hcd driver a few unused fields and some unnecessary tests against NULL and assignments to NULL. In fact it wasn't until fairly recently that the tests became unnecessary. Before last winter it was possible that the driver's stop() routine would get called even if the start() routine returned an error, but now that can't happen. Hence there's no longer any need to check for partial initialization. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] remove some USB_SUSPEND dependenciesDavid Brownell2005-10-28
| | | | | | | | | | | | | | | | | | | | This simplifies some of the PM-related #ifdeffing by recognizing that USB_SUSPEND depends on PM. Also, OHCI drivers were often testing for USB_SUSPEND when they should have tested just PM.

* [PATCH] remove duplicated resume path codeDavid Brownell2005-10-28
| | | | | | | | | | This gets rid of some inconsistently duplicated logic to resume interfaces. Similar code was in both finish_port_resume() and in usb_generic_resume(). Now there is just one copy of that code, accessed regardless of whether CONFIG_USB_SUSPEND is enabled. Fault handling is also more consistent.

* [PATCH] remove usb_suspend_device() parameterDavid Brownell2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | This patch removes the extra usb_suspend_device() parameter. The original reason to pass that parameter was so that this routine could suspend any active children. A previous patch removed that functionality ... leaving no reason to pass the parameter. A close analogy is pci_set_power_state, which doesn't need a pm_message_t either. On the internal code path that comes through the driver model, the parameter is now used to distinguish cases where USB devices need to "freeze" but not suspend. It also checks for an error case that's accessible through sysfs: attempting to suspend a device before its interfaces (or for hubs, ports).

* [PATCH] remove suspend-path recursionDavid Brownell2005-10-28
| | | | | | | | | | | | | | | | This patch removes some recursion in the CONFIG_USB_SUSPEND logic, which suspended children (of devices or hubs) that weren't already suspended. When it sees such cases, suspend now just fails cleanly. That logic was not needed during system-wide sleep state transitions; and given the current notions of how to manage selective suspend transitions, we don't want it there either. Where it was particularly handy was coping with various limitations of the sysfs "echo -n N > power/state" support. (These include assuming that "N" is always meaningful to the driver; and that drivers can only transition to state N from state zero.)

* [PATCH] usb_interface power stateDavid Brownell2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the handling of power state for USB interfaces. - Formalizes an existing invariant: interface "power state" is a boolean: ON when I/O is allowed, and FREEZE otherwise. It does so by defining some inlined helpers, then using them. - Adds a useful invariant: the only interfaces marked active are those bound to non-suspended drivers. Later patches build on this invariant. - Simplifies the interface driver API (and removes some error paths) by removing the requirement that they record power state changes during suspend and resume callbacks. Now usbcore does that. A few drivers were simplified to address that last change.

* [PATCH] USB: move handoff codeDavid Brownell2005-10-28
| | | | | | | | | | | | | | | | | | | | | This moves the PCI quirk handling for USB host controllers from the PCI directory to the USB directory. Follow-on patches will need to: (a) merge these copies with the originals in the HCD reset methods. they don't wholly agree, despite doing the very same thing; and (b) eventually change it so "usb-handoff" is the default, to help get more robust USB/BIOS/input/... interactions.

| * [PATCH] PCI fixup for Toshiba laptops and ohci1394Jesse Barnes2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a fix for a bug I see on my Toshiba laptop, where the ohci1394 controller gets initialized improperly. The patch adds two PCI fixups to arch/i386/pci/fixup.c, one that happens early on to cache the value of the PCI_CACHE_LINE_SIZE config register, and another that later restores the value, along with a valid IRQ number and some BAR values. I've tested it on my laptop, and it prevents me from running into what I consider to be a major bug: IRQ 11 is disabled by the IRQ debug code, causing my wireless to break. Thanks to Rob for the original patch to ohci1394.c and Stefan for lots of proofreading (and a last minute bug caught in review!) and additional information collection. I think the DMI system list is correct, but we may need to add some more PCI IDs to the PCI_FIXUP macros over time.

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.

| * [PATCH] PCI: Block config access during BISTBrian King2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PCI adapters (eg. ipr scsi adapters) have an exposure today in that they issue BIST to the adapter to reset the card. If, during the time it takes to complete BIST, userspace attempts to access PCI config space, the host bus bridge will master abort the access since the ipr adapter does not respond on the PCI bus for a brief period of time when running BIST. On PPC64 hardware, this master abort results in the host PCI bridge isolating that PCI device from the rest of the system, making the device unusable until Linux is rebooted. This patch is an attempt to close that exposure by introducing some blocking code in the PCI code. When blocked, writes will be humored and reads will return the cached value. Ben Herrenschmidt has also mentioned that he plans to use this in PPC power management.
