From 2eda66f4a0b9803c6a85d5e5ccd8e802bd23b998 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 30 Nov 2008 12:17:10 +0100 Subject: Bluetooth: Add fine grained mem_flags usage to btusb driver The URB submission routines need more fine grained control for the mem_flags used by kmalloc(), usb_alloc_urb() and usb_submit_urb() to better support different caller situations. Add a mem_flags parameter and give the caller full control.

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.
