* driver core: Change function call order in device_bind_driver().Cornelia Huck2007-02-07
| | | | | | | | | | | Change function call order in device_bind_driver(). If we create symlinks (which might fail) before adding the device to the list we don't have to clean up afterwards (which we didn't).

* driver core: Don't stop probing on ->probe errors.Cornelia Huck2007-02-07
| | | | | | | | | | | | Don't stop on the first ->probe error that is not -ENODEV/-ENXIO. There might be a driver registered returning an unresonable return code, and this stops probing completely even though it may make sense to try the next possible driver. At worst, we may end up with an unbound device. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* driver core: Allow device_move(dev, NULL).Cornelia Huck2007-02-07
| | | | | | | | | | | | | | | | If we allow NULL as the new parent in device_move(), we need to make sure that the device is placed into the same place as it would if it was newly registered: - Consider the device virtual tree. In order to be able to reuse code, setup_parent() has been tweaked a bit. - kobject_move() can fall back to the kset's kobject. - sysfs_move_dir() uses the sysfs root dir as fallback.

| * USB HID: handle multi-interface devices for Apple macbook pro properlySoeren Sonnenburg2007-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | Some HID devices by Apple have both keyboard and mouse interfaces; the keyboard interface is handled by usbhid, but the mouse (really touchpad) interface must be handled by the separate 'appletouch' driver. Using HID_QUIRK_IGNORE will make hiddev ignore both interfaces, therefore a new quirk flag to ignore only the mouse interface is required.

| | | | | | | | | | | | | | | | | | | | | | | | CONFIG_INPUT_DEBUG is non-existent option, so remove anything depending on it.

| | | | | | | | | | | | | | | | | | hidinput_{open,close}() functions do not belong to usbhid, but to the generic HID layer.

| | | | | | | | | | | | | | | | | | | | | | hid-debug.h contains a lot of code, and should not therefore be a header. This patch moves the code to generic hid layer as .c source, and introduces CONFIG_HID_DEBUG to conditionally compile it, instead of playing with #define DEBUG and including hid-debug.h.

| * hid: quirk for multi-input devices with unneeded output reportsAnssi Hannula2007-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new quirk HID_QUIRK_SKIP_OUTPUT_REPORTS to skip output reports when enumerating reports on a hid-input device. Add this quirk and HID_QUIRK_MULTI_INPUT to 0810:0001. PantherLord Twin USB Joystick, 0810:0001 has separate input reports for 2 distinct game controllers in the same interface, so it needs HID_QUIRK_MULTI_INPUT. However, the device also contains one output report per controller which is used to control the force feedback function, and we do not want those to appear as separate input devices as well. The simplest approach seems to be to add a quirk to skip output reports on 0810:0001, and allow the force feedback driver to handle those.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iWARP connection manager uses the ib_addr services to do route resolution (neighbour discovery in the IP world). The ib_addr netevent callback routine, however, currently only acts on InfiniBand neighbour updates. It needs to act on ethernet neighbour updates as well. This patch just removes filtering on device type altogether and will trigger on any neighour updates where the nud_type is valid. This simplifies the code some.

| * | IB/srp: Don't wait for response when QP is in error state.Ishai Rabinovitz2007-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there is a call to send_tsk_mgmt SRP posts a send and waits for 5 seconds to get a response. When the QP is in the error state it is obvious that there will be no response so it is quite useless to wait. In fact, the timeout causes SRP to wait a long time to reconnect when a QP error occurs. (Each abort and each reset_device calls send_tsk_mgmt, which waits for the timeout). The following patch solves this problem by identifying the failure and returning an immediate error code.

| * | IB: Return qp pointer as part of ib_wcMichael S. Tsirkin2007-02-04
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | struct ib_wc currently only includes the local QP number: this matches the IB spec, but seems mostly useless. The following patch replaces this with the pointer to qp itself, and updates all low level drivers and all users. This has the following advantages: - Ability to get a per-qp context through wc->qp->qp_context - Existing drivers already have the qp pointer ready in poll cq, so this change actually saves a tiny bit (extra memory read) on data path (for ehca it would actually be expensive to find the QP pointer when polling a CQ, but ehca does not support SRQ so we can leave wc->qp as NULL for ehca) - Users that need the QP number can still get it through wc->qp->qp_num Use case: In IPoIB connected mode code, I have a common CQ shared by multiple QPs. To track connection usage, I need a way to get at some per-QP context upon the completion, and I would like to avoid allocating context object per work request just to stick a QP pointer into it. With this code, I can just use wc->qp->qp_context. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Allow the host drivers to specify this and make sure we avoid hitting this limit. Also change the max_sectors field to avoid confusion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware does not say whether card was inserted or removed when reporting socket events. Moreover, during suspend, media can be removed or switched to some other card type without notification. Therefore, for each socket in the change set the following is performed: 1. If there's active device in the socket it's unregistered 2. Media detection is performed 3.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support correct suspend and resume several changes were needed: 1. Switch from work_struct to tasklet for command handling. When device suspend is called workqueues are already frozen and can not be used. 2. Separate host initialization code from driver's probe and don't rely on interrupts for host initialization. This, in turn, addresses two problems: a) Resume needs to re-initialize the host, but can not assume that device interrupts were already re-armed. b) Previously, probe will return successfully before really knowing the state of the host, as host interrupts were not armed in time. Now it uses polling to determine the real host state before returning. 3. Separate termination code from driver's remove. Termination may be caused by resume, if media changed type or became unavailable during suspend. Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
