* wusb: add link wusb-usb deviceInaky Perez-Gonzalez2008-04-241-0/+2
| | | | | | | | | | | | | | | | | | | | We need to tie the WUSB and USB devices; the USB stack doesn't need to know the details about the WUSB device, but needs to have a link to it. This is needed so that the notify call back for Remove Device can tie both and undo the device setup (sysfs files). We connect the devices together at the Add Device notifier callback (the wusb_dev references the usb_dev and stores it, the usb_dev references the wusb_dev and stores it); then we do create the WUSB sysfs files at the usb_dev sysfs directory. At Remove Device, we undo that (thus we need the usb_dev reference). Cross reference to functions in the WUSB substack: wusb_dev_{add,rm}_ncb().

* USB: Export suspend statisticsSarah Sharp2008-02-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | This patch exports two statistics to userspace: /sys/bus/usb/device/.../power/connected_duration /sys/bus/usb/device/.../power/active_duration connected_duration is the total time (in msec) that the device has been connected. active_duration is the total time the device has not been suspended. With these two statistics, tools like PowerTOP can calculate the percentage time that a device is active, i.e. not suspended or auto-suspended. Users can also use the active_duration to check if a device is actually autosuspended. Currently, they can set power/level to auto and power/autosuspend to a positive timeout, but there's no way to know from userspace if a device was actually autosuspended without looking at the dmesg output. These statistics will be useful in creating an automated userspace script to test autosuspend for USB devices.

* USB: keep track of whether interface sysfs files existAlan Stern2007-11-281-0/+1
| | | | | | | | | | This patch (as1009) solves the problem of multiple registrations for USB sysfs files in a more satisfying way than the existing code. It simply adds a flag to keep track of whether or not the files have been created; that way the files can be created or removed as needed. Signed-off-by: Alan Stern <stern@rowland.harvard.edu>
* USB: skip autosuspended devices during system resumeAlan Stern2007-10-121-0/+1
| | | | | | | | | | | | | | | System suspends and hibernation are supposed to be as transparent as possible. By this reasoning, if a USB device is already autosuspended before the system sleep begins then it should remain autosuspended after the system wakes up. This patch (as1001) adds a skip_sys_resume flag to the usb_device structure and uses it to avoid waking up devices which were suspended when a system sleep began.

* USB: flush outstanding URBs when suspendingAlan Stern2007-10-121-0/+1
| | | | | | | | | | | | | | | | | | | | This patch (as989) makes usbcore flush all outstanding URBs for each device as the device is suspended. This will be true even when CONFIG_USB_SUSPEND is not enabled. In addition, an extra can_submit flag is added to the usb_device structure. That flag will be turned off whenever a suspend request has been received for the device, even if the device isn't actually suspended because CONFIG_USB_SUSPEND isn't set. It's no longer necessary to check for the device state being equal to USB_STATE_SUSPENDED during URB submission; that check can be replaced by a check of the can_submit flag. This also permits us to remove some questionable references to the deprecated power.power_state field.

To help simplify the HCDs, usbcore will check urb->unlinked before calling the completion handler; if the value is set it will automatically override the status reported by the HCD.

* usb: introduce usb_device authorization bitsInaky Perez-Gonzalez2007-10-121-0/+7
| | | | | | | | | | | | This just modifies 'struct usb_device' to contain the 'authorized' bit. It also adds a 'wusb' bit. This is needed because nonauthorized (and thus non-authenticated) wusb devices will fail certain kind of simple requests (such as string descriptors).

* USB: cleanup for previous patchesAlan Stern2007-10-121-1/+1
| | | | | | | | | | | | | | | This patch (as951) cleans up a few loose ends from earlier patches. Redundant checks for non-NULL urb->dev are removed, as are checks of urb->dev->bus (which can never be NULL). Conversely, a check for non-NULL urb->ep is added to the unlink paths. A homegrown round-down-to-power-of-2 loop is simplified by using the ilog2 routine. The comparison in usb_urb_dir_in() is made more transparent.

* USB: avoid using urb->pipe in usbcoreAlan Stern2007-10-121-3/+3
| | | | | | | | | | | | | | This patch (as946) eliminates many of the uses of urb->pipe in usbcore. Unfortunately there will have to be a significant API change, affecting all USB drivers, before we can remove it entirely. This patch contents itself with changing only the interface to usb_buffer_map_sg() and friends: The pipe argument is replaced with a direction flag. That can be done easily because those routines get used in only one place. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: add direction bit to urb->transfer_flagsAlan Stern2007-10-121-0/+30
| | | | | | | | | | | | | | | | | | This patch (as945) adds a bit to urb->transfer_flags for recording the direction of the URB. The bit is set/cleared automatically in usb_submit_urb() so drivers don't have to worry about it (although as a result, it isn't valid until the URB has been submitted). Inline routines are added for easily checking an URB's direction. They replace calls to usb_pipein in the DMA-mapping parts of hcd.c. For non-control endpoints, the direction is determined directly from the endpoint descriptor. However control endpoints are bi-directional; for them the direction is determined from the bRequestType byte and the wLength value in the setup packet.

* USB: add ep->enableAlan Stern2007-10-121-0/+2
| | | | | | | | | | | | | | | | | | This patch (as944) adds an explicit "enabled" field to the usb_host_endpoint structure and uses it in place of the current mechanism. This is merely a time-space tradeoff; it makes checking whether URBs may be submitted to an endpoint simpler. The existing mechanism is efficient when converting urb->pipe to an endpoint pointer, but it's not so efficient when urb->ep is used instead. As a side effect, the procedure for enabling an endpoint is now a little more complicated. The ad-hoc inline code in usb.c and hub.c for enabling ep0 is now replaced with calls to usb_enable_endpoint, which is no longer static.

* USB: add urb->epAlan Stern2007-10-121-0/+26
| | | | | | | | | | | | | | | | | | | This patch (as943) prepares the way for eliminating urb->pipe by introducing an endpoint pointer into struct urb. For now urb->ep is set by usb_submit_urb() from the pipe value; eventually drivers will set it themselves and we will remove urb->pipe completely. The patch also adds new inline routines to retrieve an endpoint descriptor's number and transfer type, essentially as replacements for usb_pipeendpoint and usb_pipetype. usb_submit_urb(), usb_hcd_submit_urb(), and usb_hcd_unlink_urb() are converted to use the new field and new routines. Other parts of usbcore will be converted in later patches. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: add power/persist device attributeAlan Stern2007-07-121-0/+1
| | | | | | | | | | | | | | | | | | | | | This patch (as920) adds an extra level of protection to the USB-Persist facility. Now it will apply by default only to hubs; for all other devices the user must enable it explicitly by setting the power/persist device attribute. The disconnect_all_children() routine in hub.c has been removed and its code placed inline. This is the way it was originally as part of hub_pre_reset(); the revised usage in hub_reset_resume() is sufficiently different that the code can no longer be shared. Likewise, mark_children_for_reset() is now inline as part of hub_reset_resume(). The end result looks much cleaner than before. The sysfs interface is updated to add the new attribute file, and there are corresponding documentation updates.

* USB: add reset_resume methodAlan Stern2007-07-121-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as918) introduces a new USB driver method: reset_resume. It is called when a device needs to be reset as part of a resume procedure (whether because of a device quirk or because of the USB-Persist facility), thereby taking over a role formerly assigned to the post_reset method. As a consequence, post_reset no longer needs an argument indicating whether it is being called as part of a reset-resume. This separation of functions makes the code clearer. In addition, the pre_reset and post_reset method return types are changed; they now must return an error code. The return value is unused at present, but at some later time we may unbind drivers and re-probe if they encounter an error during reset handling. The existing pre_reset and post_reset methods in the usbhid, usb-storage, and hub drivers are updated to match the new requirements. For usbhid the post_reset routine is also used for reset_resume (duplicate method pointers); for the other drivers a new reset_resume routine is added. The change to hub.c looks bigger than it really is, because mark_children_for_reset_resume() gets moved down next to the new hub_reset_resume() routine. A minor change to usb-storage makes the usb_stor_report_bus_reset() routine acquire the host lock instead of requiring the caller to hold it already.

| | | | | | | | | | | | | | Recently, the USB device matching code stopped matching generic interface matches against devices with vendor-specific device class values.

* USB: add USB-Persist facilityAlan Stern2007-07-121-2/+6
| | | | | | | | | | | | | | | | | This patch (as886) adds the controversial USB-persist facility, allowing USB devices to persist across a power loss during system suspend. The facility is controlled by a new Kconfig option (with appropriate warnings about the potential dangers); when the option is off the behavior will remain the same as it is now. But when the option is on, people will be able to use suspend-to-disk and keep their USB filesystems intact -- something particularly valuable for small machines where the root filesystem is on a USB device!

* USB: add "last_busy" field for use in autosuspendAlan Stern2007-04-271-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as877) adds a "last_busy" field to struct usb_device, for use by the autosuspend framework. Now if an autosuspend call comes at a time when the device isn't busy but hasn't yet been idle for long enough, the timer can be set to exactly the desired value. And we will be ready to handle things like HID drivers, which can't maintain a useful usage count and must rely on the time-of-last-use to decide when to autosuspend. The patch also makes some related minor improvements: Move the calls to the autosuspend condition-checking routine into usb_suspend_both(), which is the only place where it really matters. If the autosuspend timer is already running, don't stop and restart it. Replace immediate returns with gotos so that the optional debugging ouput won't be bypassed. If autoresume is disabled but the device is already awake, don't return an error for an autoresume call. Don't try to autoresume a device if it isn't suspended. (Yes, this undercuts the previous change -- so sue me.) Don't duplicate existing code in the autosuspend work routine. Fix the kerneldoc in usb_autopm_put_interface(): If an autoresume call fails, the usage counter is left unchanged.

* USB: make usbdevices export their device nodes instead of using a separate classKay Sievers2007-04-271-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o The "real" usb-devices export now a device node which can populate /dev/bus/usb. o The usb_device class is optional now and can be disabled in the kernel config. Major/minor of the "real" devices and class devices are the same. o The environment of the usb-device event contains DEVNUM and BUSNUM to help udev and get rid of the ugly udev rule we need for the class devices. o The usb-devices and usb-interfaces share the same bus, so I used the new "struct device_type" to let these devices identify themselves. This also removes the current logic of using a magic platform-pointer. The name of the device_type is also added to the environment which makes it easier to distinguish the different kinds of devices on the same subsystem. It looks like this: add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1 ACTION=add DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1 SUBSYSTEM=usb SEQNUM=1533 MAJOR=189 MINOR=131 DEVTYPE=usb_device PRODUCT=46d/c03e/2000 TYPE=0/0/0 BUSNUM=002 DEVNUM=004 This udev rule works as a replacement for usb_device class devices: SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \ NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644" Updated patch, which needs the device_type patches in Greg's tree.

| * usbcore: remove unused bandwith-related codeAlan Stern2007-02-071-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as841) removes from usbcore a couple of support routines meant to help with bandwidth allocation. With the changes to uhci-hcd in the previous patch, these routines are no longer used anywhere. Also removed is the CONFIG_USB_BANDWIDTH option; it no longer does anything and is no longer needed since the HCDs now handle bandwidth issues correctly.

| * USB serial: add dynamic id support to usb-serial coreGreg Kroah-Hartman2007-02-071-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to Johannes Hölzl <johannes.hoelzl@gmx.de> for fixing a few things and getting it all working properly. This adds support for dynamic usb ids to the usb serial core. The file "new_id" will show up under the usb serial driver, not the usb driver associated with the usb-serial driver (yeah, it can be a bit confusing at first glance...) This patch also modifies the USB core to allow the usb-serial core to reuse much of the dynamic id logic.
