See https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/ microsoft-defined-bluetooth-hci-commands-and-events for more information about the extension. This was verified with Intel ThunderPeak BT controller where msft_vnd_ext_opcode is 0xFC1E. Signed-off-by: Miao-chen Chou --- Changes in v1: - Add a bit mask of driver_info for Microsoft vendor extension. - Indicates the support of Microsoft vendor extension for Intel 9460/9560 and 9160/9260. - Add fields to struct hci_dev to facilitate the support of Microsoft vendor extension. drivers/bluetooth/btusb.c | 18 ++++++++++++++++-- include/net/bluetooth/hci.h | 2 ++ include/net/bluetooth/hci_core.h | 4 ++++ 3 files changed, 22 insertions(+), 2 deletions(-) diff --git a/drivers/bluetooth/btusb.c b/drivers/bluetooth/btusb.c index 3bdec42c9612..5eb27d1c4ac7 100644 --- a/drivers/bluetooth/btusb.c +++ b/drivers/bluetooth/btusb.c @@ -58,6 +58,7 @@ static struct usb_driver btusb_driver; #define BTUSB_CW6622 0x100000 #define BTUSB_MEDIATEK 0x200000 #define BTUSB_WIDEBAND_SPEECH 0x400000 +#define BTUSB_MSFT_VND_EXT 0x800000 static const struct usb_device_id btusb_table[] = { /* Generic Bluetooth USB device */ @@ -335,7 +336,8 @@ static const struct usb_device_id blacklist_table[] = { /* Intel Bluetooth devices */ { USB_DEVICE(0x8087, 0x0025), .driver_info = BTUSB_INTEL_NEW | - BTUSB_WIDEBAND_SPEECH }, + BTUSB_WIDEBAND_SPEECH | + BTUSB_MSFT_VND_EXT }, { USB_DEVICE(0x8087, 0x0026), .driver_info = BTUSB_INTEL_NEW | BTUSB_WIDEBAND_SPEECH }, { USB_DEVICE(0x8087, 0x0029), .driver_info = BTUSB_INTEL_NEW | @@ -348,7 +350,8 @@ static const struct usb_device_id blacklist_table[] = { { USB_DEVICE(0x8087, 0x0aa7), .driver_info = BTUSB_INTEL | BTUSB_WIDEBAND_SPEECH }, { USB_DEVICE(0x8087, 0x0aaa), .driver_info = BTUSB_INTEL_NEW | - BTUSB_WIDEBAND_SPEECH }, + BTUSB_WIDEBAND_SPEECH | + BTUSB_MSFT_VND_EXT }, /* Other Intel Bluetooth devices */ { USB_VENDOR_AND_INTERFACE_INFO(0x8087, 0xe0, 0x01, 0x01), @@ -3734,6 +3737,11 @@ static int btusb_probe(struct usb_interface *intf, hdev->send = btusb_send_frame; hdev->notify = btusb_notify; + hdev->msft_vnd_ext_opcode = HCI_OP_NOP; + hdev->msft_vnd_ext_features = 0; + hdev->msft_vnd_ext_evt_prefix_len = 0; + hdev->msft_vnd_ext_evt_prefix = NULL; + #ifdef CONFIG_PM err = btusb_config_oob_wake(hdev); if (err) @@ -3800,6 +3808,12 @@ static int btusb_probe(struct usb_interface *intf, set_bit(HCI_QUIRK_STRICT_DUPLICATE_FILTER, &hdev->quirks); set_bit(HCI_QUIRK_SIMULTANEOUS_DISCOVERY, &hdev->quirks); set_bit(HCI_QUIRK_NON_PERSISTENT_DIAG, &hdev->quirks); + + if (id->driver_info & BTUSB_MSFT_VND_EXT && + (id->idProduct == 0x0025 || id->idProduct == 0x0aaa)) { + hdev->msft_vnd_ext_opcode = + hci_opcode_pack(HCI_VND_DEBUG_CMD_OGF, 0x001E); + } } if (id->driver_info & BTUSB_MARVELL) diff --git a/include/net/bluetooth/hci.h b/include/net/bluetooth/hci.h index 5f60e135aeb6..b85e95454367 100644 --- a/include/net/bluetooth/hci.h +++ b/include/net/bluetooth/hci.h @@ -38,6 +38,8 @@ #define HCI_MAX_CSB_DATA_SIZE 252 +#define HCI_VND_DEBUG_CMD_OGF 0x3f + /* HCI dev events */ #define HCI_DEV_REG 1 #define HCI_DEV_UNREG 2 diff --git a/include/net/bluetooth/hci_core.h b/include/net/bluetooth/hci_core.h index d4e28773d378..15daf3b2d4f0 100644 --- a/include/net/bluetooth/hci_core.h +++ b/include/net/bluetooth/hci_core.h @@ -315,6 +315,10 @@ struct hci_dev { __u8 ssp_debug_mode; __u8 hw_error_code; __u32 clock; + __u16 msft_vnd_ext_opcode; + __u64 msft_vnd_ext_features; + __u8 msft_vnd_ext_evt_prefix_len; + void *msft_vnd_ext_evt_prefix; __u16 devid_source; __u16 devid_vendor;
