It also adds macros to set/test/get the flags. Signed-off-by: Hilda Wu --- Changes in v4: - Since the original 0002 patch has no dependency with this 0001 patch. So let the 0002 patch submit another. Changes in v3: - Update private flag. Changes in v2: - Set the proper priv_size to hci_alloc_dev_priv(). - Separate commits for functions. --- --- drivers/bluetooth/btrtl.h | 21 +++++++++++++++++++++ drivers/bluetooth/btusb.c | 3 +++ 2 files changed, 24 insertions(+) diff --git a/drivers/bluetooth/btrtl.h b/drivers/bluetooth/btrtl.h index 2c441bda390a..ebf0101c959b 100644 --- a/drivers/bluetooth/btrtl.h +++ b/drivers/bluetooth/btrtl.h @@ -47,6 +47,27 @@ struct rtl_vendor_config { struct rtl_vendor_config_entry entry[]; } __packed; +enum { + REALTEK_ALT6_CONTINUOUS_TX_CHIP, + + __REALTEK_NUM_FLAGS, +}; + +struct btrealtek_data { + DECLARE_BITMAP(flags, __REALTEK_NUM_FLAGS); +}; + +#define btrealtek_set_flag(hdev, nr) \ + do { \ + struct btrealtek_data *realtek = hci_get_priv((hdev)); \ + set_bit((nr), realtek->flags); \ + } while (0) + +#define btrealtek_get_flag(hdev) \ + (((struct btrealtek_data *)hci_get_priv(hdev))->flags) + +#define btrealtek_test_flag(hdev, nr) test_bit((nr), btrealtek_get_flag(hdev)) + #if IS_ENABLED(CONFIG_BT_RTL) struct btrtl_device_info *btrtl_initialize(struct hci_dev *hdev, diff --git a/drivers/bluetooth/btusb.c b/drivers/bluetooth/btusb.c index 271963805a38..4243936c0583 100644 --- a/drivers/bluetooth/btusb.c +++ b/drivers/bluetooth/btusb.c @@ -3755,6 +3755,9 @@ static int btusb_probe(struct usb_interface *intf, /* Override the rx handlers */ data->recv_event = btusb_recv_event_intel; data->recv_bulk = btusb_recv_bulk_intel; + } else if (id->driver_info & BTUSB_REALTEK) { + /* Allocate extra space for Realtek device */ + priv_size += sizeof(struct btrealtek_data); } data->recv_acl = hci_recv_frame;
