2005-10-28[PATCH] USB: usb_bulk_message() handles interrupts endpointsAlan Stern
Because there is no bulk_interrupt_message() routine and no USBDEVFS_INTERRUPT ioctl, people have been forced to abuse the usb_bulk_message() routine and USBDEVFS_BULK by using them for interrupt transfers as well as bulk transfers. This patch (as567) formalizes this practice and adds code to usb_bulk_message() for detecting when the target is really an interrupt endpoint. If it is, the routine submits an interrupt URB (using the default interval) instead of a bulk URB. In theory this should help HCDs that don't like it when people try to mix transfer types, queuing both periodic and non-periodic types for the same endpoint. Not fully tested -- I don't have any programs that use USBDEVFS_BULK for interrupt transfers -- but it compiles okay and normal bulk messages work as well as before.

2005-10-28[PATCH] updates for "controller suspended" handlingDavid Brownell
Reject URBs to _all_ devices when their host controllers are suspended; even root hub registers will be unavailable. Also, don't reject urbs to root hubs in other cases; the only upstream link is through that controller (on PCI or whatever SOC bus is in use).

2005-10-28[PATCH] stop exporting two functionsDavid Brownell

2005-10-28[PATCH] update PCI early-handoff handling for OHCIDavid Brownell
The PCI "early usb handoff" quirk logic didn't work like "ohci-hcd" ... This patch makes it do so by: - Resetting the controller after kicking BIOS off, matching the normal "chip in hardware reset" startup mode; - Reporting any BIOS that borks this simple handoff; it's likely got a few other surprises for us too. - Ignoring that handoff on HPPA; The diagnostic string is mostly shared with EHCI, saving a few bytes.

2005-10-28[PATCH] OHCI PM updatesDavid Brownell
This simplifies the OHCI root hub suspend logic: - Uses new usbcore root hub calls to make autosuspend work again: * Uses a newish usbcore root hub wakeup mechanism, making requests to khubd not keventd. * Uses an even newer sibling suspend hook. - Expect someone always made usbcore call ohci_hub_suspend() before bus glue fires; and that ohci_hub_resume() is only called after that bus glue ran. Previously, only CONFIG_USB_SUSPEND promised those things. (Includes updates to PCI and OMAP bus glue.) - Handle a not-noticed-before special case during resume from one of the swsusp snapshots when using "usb-handoff": the controller isn't left in RESET state. (A bug to fix in the usb-handoff code...) Also cleans up a minor debug printk glitch, and switches an mdelay over to an msleep (how did that stick around for so long?).

2005-10-28[PATCH] usbcore PCI glue updates for PMDavid Brownell
This updates the PCI glue to address the new and simplified usbcore suspend semantics, where CONFIG_USB_SUSPEND becomes irrelevant to HCDs because hcd->hub_suspend() will always be called. - Removes now-unneeded recursion support - Go back to ignoring faults reported by the wakeup calls; we expect them to fail sometimes, and that's just fine. The PCI HCDs will need simple changes to catch up to this, like being able to ignore the setting of CONFIG_USB_SUSPEND.

2005-10-28[PATCH] root hub updates (greater half)David Brownell
This patch associates hub suspend and resume logic (including for root hubs) with CONFIG_PM -- instead of CONFIG_USB_SUSPEND as before -- thereby unifying two troublesome versions of suspend logic into just one. It'll be easier to keep things right from now on. - Now usbcore _always_ calls hcd->hub_suspend as needed, instead of only when USB_SUSPEND is enabled: * Those root hub methods are now called from hub suspend/resume; no more skipping between layers during device suspend/resume; * It now handles cases allowed by sysfs or autosuspended root hubs, by forcing the hub interface to resume too. - All devices, including virtual root hubs, now get the same treatment on their resume paths ... including re-activating all their interfaces. Plus it gets rid of those stub copies of usb_{suspend,resume}_device(), and updates the Kconfig to match the new definition of USB_SUSPEND: it provides (a) selective suspend, downstream from hubs; and (b) remote wakeup, upstream from any device configuration which supports it. This calls for minor followup patches for most HCDs (and their PCI glue).

2005-10-28[PATCH] root hub changes (lesser half)David Brownell
This patch collects various small updates related to root hubs, to shrink later patches which build on them. - For root hub suspend/resume support: * Make the existing usb_hcd_resume_root_hub() routine respect pmcore locking, exporting and using the dpm_runtime_resume() method. * Add a new usb_hcd_suspend_root_hub() to pair with that routine. (Essential to make OHCI autosuspend behave again...) * HC_SUSPENDED by itself only refers to the root hub's downstream ports. So let HCDs see root hub URBs unless the parent device is suspended. - Remove an assertion we no longer need (and now, also don't want). - Generic suspend/resume updates to work better with swsusp. * Ignore the FREEZE vs SUSPEND distinction for hardware; trying to use it breaks the swsusp snapshots it's supposed to help (sigh). * On resume, mark devices as resumed right away, but then do nothing else if the device is marked NOTATTACHED. These changes shouldn't be very noticable by themselves.

This cleans up a small recent FIXME, ensuring that all the HCDs provide root hub suspend/resume methods. It also wraps the calls to those root suspend routines just like on the PCI "USB_SUSPEND not defined" cases, so non-PCI bus glue won't be as tempted to behave very differently.

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.

2005-10-28[PATCH] remove duplicated resume path codeDavid Brownell
This gets rid of some inconsistently duplicated logic to resume interfaces. Similar code was in both finish_port_resume() and in usb_generic_resume().

2005-10-28[PATCH] remove usb_suspend_device() parameterDavid Brownell
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).

2005-10-28[PATCH] remove suspend-path recursionDavid Brownell
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.)

2005-10-28[PATCH] usb_interface power stateDavid Brownell
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.

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.

Info about resources assigned to PCI devices is already available through sysfs and pci utilities. There's no need for shpchp to create another sysfs file to display the same information. Signed-off-by: Rajesh Shah <rajesh.shah@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2005-10-28[PATCH] shpchp: use the PCI core for hotplug resource managementrajesh.shah@intel.com
This patch converts the standard hotplug controller driver to use the PCI core for resource management. This eliminates a whole lot of duplicated code, and integrates shpchp in the system's normal PCI handling code.

2005-10-28[PATCH] ppc64 PCI Hotplug: cleanup unsymmetric API routineslinas
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).
