2009-08-24Bluetooth: Add USB autosuspend support to btusb driverOliver Neukum1-20/+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. Add #ifdefs for CONFIG_PM as necessary. Signed-off-by: Oliver Neukum <oliver@neukum.org> Tested-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-08-24Bluetooth: Fix false errors from bcsp_pkt_cull functionWending Weng1-1/+2
The error message "Removed only %u out of %u pkts" is printed when multiple to be acked packets are queued. if (i++ >= pkts_to_be_removed) break; This will break out of the loop and increase the counter i when i==pkts_to_be_removed and the loop ends up with i=pkts_to_be_removed+1. The following line if (i != pkts_to_be_removed) { BT_ERR("Removed only %u out of %u pkts", i, pkts_to_be_removed); } will then display the false message. The counter i must not increase on the same statement. Signed-off-by: Wending Weng <wweng@rheinmetall.ca> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2009-08-22Bluetooth: Remove Enter/Leave debug statements from Marvell driverMarcel Holtmann2-219/+23
The Marvell Bluetooth driver is full of Enter/Leave debug statements and all of them are really pointless and only clutter the code. Seems to be some left-overs when they ported the driver from Windows. For the Linux driver lets remove these. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2009-08-22Bluetooth: Remove private device name of Marvell SDIO driverMarcel Holtmann2-5/+0
For some reason the btmrvl_device struct has a name field that the SDIO fills in, but then never ever uses again. That is totally pointless and so just remove it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2009-08-22Bluetooth: Remove pointless ifdef protection for Marvell header filesMarcel Holtmann2-10/+0

2009-08-22Bluetooth: Fix compilation of Marvell driver without debugfsMarcel Holtmann1-1/+3
The Makefile entry for the Marvell driver is broken when it comes to handling the optional DEBUG_FS correctly. That must have been the reason why they were using select in Kconfig in the first place. Fix this and make it really optional. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2009-08-22Bluetooth: Fix Kconfig for Marvell Bluetooth driverMarcel Holtmann1-2/+1
The Marvell driver selects DEBUG_FS and FW_LOADER for its core driver and that is pointless. Don't select DEBUG_FS since it is either enabled or not and it is not for the driver to enable it. Also FW_LOADER is only used within the SDIO driver and so just have that one select the FW_LOADER option. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2009-06-11tty: fix bluetooth scribbling on low latency flagsAlan Cox1-1/+0

2009-06-11tty: rewrite the ldisc lockingAlan Cox1-2/+2
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>
2009-06-08Bluetooth: Remove unused and unneeded support in virtual driverMarcel Holtmann1-31/+0

2009-06-08Bluetooth: Remove BKL from open callback of virtual driverMarcel Holtmann1-4/+0

2009-06-08Bluetooth: Use wait_event_interruptible for virtual driverMarcel Holtmann1-28/+15

2009-02-27Bluetooth: Submit bulk URBs along with interrupt URBsMarcel Holtmann1-17/+23
Submitting the bulk URBs for ACL data transfers only on demand has no real benefit compared to just submit them when a Bluetooth device gets opened. So when submitting the interrupt URBs for HCI events, just submit the bulk URBs, too. This solves a problem with some Bluetooth USB dongles that has been reported over the last few month. These devices require that the bulk URBs are actually present. These devices are really broken, but there is nothing we can do about it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2008-11-30Bluetooth: Send HCI Reset command by default on device initializationMarcel Holtmann3-54/+51
The Bluetooth subsystem was not using the HCI Reset command when doing device initialization. The Bluetooth 1.0b specification was ambiguous on how the device firmware was suppose to handle it. Almost every device was triggering a transport reset at the same time. In case of USB this ended up in disconnects from the bus. All modern Bluetooth dongles handle this perfectly fine and a lot of them actually require that HCI Reset is sent. If not then they are either stuck in their HID Proxy mode or their internal structures for inquiry and paging are not correctly setup. To handle old and new devices smoothly the Bluetooth subsystem contains a quirk to force the HCI Reset on initialization. However maintaining such a quirk becomes more and more complicated. This patch turns the logic around and lets the old devices disable the HCI Reset command. The only device where the HCI_QUIRK_NO_RESET is still needed are the original Digianswer devices and dongles with an early CSR firmware. CSR reported that they fixed this for version 12 firmware. The last official release of version 11 firmware is build ID 115. The first version 12 candidate was build ID 117. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
