* Bluetooth: Convert Marvell driver to use per adapter debugfsMarcel Holtmann2010-02-271-7/+7
| | | | | | | | The debugfs support of the Marvell driver is buggy. It is limited to one controller per system. Fix this by using the controller specific debugfs directory as parent. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Convert controller hdev->type to hdev->busMarcel Holtmann2010-02-2711-11/+11
| | | | | | | The hdev->type is misnamed and should be actually hdev->bus instead. So convert it now. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* Bluetooth: Redo checks in IRQ handler for shared IRQ supportMike Frysinger2010-01-304-4/+12
| | | | | | | | | | | | | | Commit ac019360fe3 changed the irq handler logic to BUG_ON rather than returning IRQ_NONE when the incoming argument is invalid. While this works in most cases, it doesn't work when the IRQ is shared with other devices (or when DEBUG_SHIRQ is enabled). So revert the previous change and replace the warning message with a comment explaining that we want this behavior.

(2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.

|/ | | | | | | | | | | | | | | | | | | | | Rafael debugged a resume-time hang (with oopses in workqueue handling) on his laptop that was due to the 'waker' workqueue entry being disconnected and then released without the workqueue entry having been synchronized. Several people were involved, with Oleg Nesterov doing a debugging patch showing what workqueue entry was corrupt etc. This was a regression introduced by commit 7bee549e19 ("Bluetooth: Add USB autosuspend support to btusb driver") as Rafael points out (not actually bisected, but it became clear once the bug was found).

* Bluetooth: Add USB autosuspend support to btusb driverOliver Neukum2009-08-251-20/+174
| | | | | | | | | | | | | | | | | | | | This patch adds support of USB autosuspend to the btusb driver. If the device doesn't support remote wakeup, simple support based on up/down is provided. If the device supports remote wakeup, additional support for autosuspend while the interface is up is provided. This is done by queueing URBs in an anchor structure and waking the device up from a work queue on sending. Reception triggers remote wakeup. The last busy facility of the USB autosuspend code is used. To close a race between autosuspend and transmission, a counter of ongoing transmissions is maintained.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several pretty much unfixable races in the old ldisc code, especially with respect to pty behaviour and also to hangup. It's easier to rewrite the code than simply try and patch it up. This patch - splits the ldisc from the tty (so we will be able to refcount it more cleanly later) - introduces a mutex lock for ldisc changing on an active device - fixes the complete mess that hangup caused - implements hopefully correct setldisc/close/hangup locking There are still some problems around pty pairs that have always been there but at least it is now possible to understand the code and fix further problems. This fixes the following known bugs - hang up can leak ldisc references - hang up may not call open/close on ldisc in a matched way - pty/tty pairs can deadlock during an ldisc change - reading the ldisc proc files can cause every ldisc to be loaded and probably a few other of the mysterious ldisc race reports. I'm sure it also adds the odd new one. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
