Miller" , Jakub Kicinski , Johan Hedberg , Luiz Augusto von Dentz , linux-kernel@vger.kernel.org, netdev@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: netdev@vger.kernel.org From: Archie Pusaka Hi linux-bluetooth, This series of patches manages the hardware offloading part of MSFT extension API. The full documentation can be accessed by this link: https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/microsoft-defined-bluetooth-hci-commands-and-events Only four of the HCI commands are planned to be implemented: HCI_VS_MSFT_Read_Supported_Features (implemented in previous patch), HCI_VS_MSFT_LE_Monitor_Advertisement, HCI_VS_MSFT_LE_Cancel_Monitor_Advertisement, and HCI_VS_MSFT_LE_Set_Advertisement_Filter_Enable. These are the commands which would be used for advertisement monitor feature. Only if the controller supports the MSFT extension would these commands be sent. Otherwise, software-based monitoring would be performed in the user space instead. Thanks in advance for your feedback! Archie Changes in v4: * Change the logic of merging add_adv_patterns_monitor with rssi * Aligning variable declaration on mgmt.h * Replacing the usage of BT_DBG with bt_dev_dbg Changes in v3: * Flips the order of rssi and pattern_count on mgmt struct * Fix return type of msft_remove_monitor Changes in v2: * Add a new opcode instead of modifying an existing one * Also implement the new MGMT opcode and merge the functionality with the old one.
