From 220915857e29795ae5ba4222806268b4a99c19c1 Mon Sep 17 00:00:00 2001 From: Alain Michaud Date: Thu, 23 Apr 2020 14:43:27 +0000 Subject: Bluetooth: Adding driver and quirk defs for multi-role LE This change adds the relevant driver and quirk to allow drivers to report the le_states as being trustworthy. This has historically been disabled as controllers did not reliably support this. In particular, this will be used to relax this condition for controllers that have been well tested and reliable. /* Most controller will fail if we try to create new connections * while we have an existing one in slave role. */ if (hdev->conn_hash.le_num_slave > 0) return NULL; Signed-off-by: Alain Michaud Signed-off-by: Marcel Holtmann --- include/net/bluetooth/hci.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'include/net') diff --git a/include/net/bluetooth/hci.h b/include/net/bluetooth/hci.h index 1da8cec8e210..e5bc1dfe809a 100644 --- a/include/net/bluetooth/hci.h +++ b/include/net/bluetooth/hci.h @@ -218,6 +218,15 @@ enum { * This quirk must be set before hci_register_dev is called. */ HCI_QUIRK_WIDEBAND_SPEECH_SUPPORTED, + + /* When this quirk is set, the controller has validated that + * LE states reported through the HCI_LE_READ_SUPPORTED_STATES are + * valid.
