IML gives flexibility to fix issues as its not possible to fix issue in Primary bootloader once flashed to ROM. This patch adds the support to download IML before downloading operational firmware image. dmesg logs: [13.399003] Bluetooth: Core ver 2.22 [13.399006] Bluetooth: Starting self testing [13.401194] Bluetooth: ECDH test passed in 2135 usecs [13.421175] Bluetooth: SMP test passed in 597 usecs [13.421184] Bluetooth: Finished self testing [13.422919] Bluetooth: HCI device and connection manager initialized [13.422923] Bluetooth: HCI socket layer initialized [13.422925] Bluetooth: L2CAP socket layer initialized [13.422930] Bluetooth: SCO socket layer initialized [13.458065] Bluetooth: hci0: Device revision is 0 [13.458071] Bluetooth: hci0: Secure boot is disabled [13.458072] Bluetooth: hci0: OTP lock is disabled [13.458072] Bluetooth: hci0: API lock is enabled [13.458073] Bluetooth: hci0: Debug lock is disabled [13.458073] Bluetooth: hci0: Minimum firmware build 1 week 10 2014 [13.458075] Bluetooth: hci0: Bootloader timestamp 2022.46 buildtype 1 build 26590 [13.458324] Bluetooth: hci0: DSM reset method type: 0x00 [13.460678] Bluetooth: hci0: Found device firmware: intel/ibt-0090-0291-iml.sfi [13.460684] Bluetooth: hci0: Boot Address: 0x30099000 [13.460685] Bluetooth: hci0: Firmware Version: 227-11.24 [13.562554] Bluetooth: hci0: Waiting for firmware download to complete [13.563023] Bluetooth: hci0: Firmware loaded in 99941 usecs [13.563057] Bluetooth: hci0: Waiting for device to boot [13.565029] Bluetooth: hci0: Malformed MSFT vendor event: 0x02 [13.565148] Bluetooth: hci0: Device booted in 2064 usecs [13.567065] Bluetooth: hci0: No device address configured [13.569010] Bluetooth: hci0: Found device firmware: intel/ibt-0090-0291.sfi [13.569061] Bluetooth: hci0: Boot Address: 0x10000800 [13.569062] Bluetooth: hci0: Firmware Version: 227-11.24 [13.788891] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [13.788897] Bluetooth: BNEP filters: protocol multicast [13.788902] Bluetooth: BNEP socket layer initialized [15.435905] Bluetooth: hci0: Waiting for firmware download to complete [15.436016] Bluetooth: hci0: Firmware loaded in 1823233 usecs [15.436258] Bluetooth: hci0: Waiting for device to boot [15.471140] Bluetooth: hci0: Device booted in 34277 usecs [15.471201] Bluetooth: hci0: Malformed MSFT vendor event: 0x02 [15.471487] Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-0090-0291.ddc [15.474353] Bluetooth: hci0: Applying Intel DDC parameters completed [15.474486] Bluetooth: hci0: Found Intel DDC parameters: intel/bdaddress.cfg [15.475299] Bluetooth: hci0: Applying Intel DDC parameters completed [15.479381] Bluetooth: hci0: Firmware timestamp 2024.10 buildtype 3 build 58595 [15.479385] Bluetooth: hci0: Firmware SHA1: 0xb4f3cc46 [15.483243] Bluetooth: hci0: Fseq status: Success (0x00) [15.483246] Bluetooth: hci0: Fseq executed: 00.00.00.00 [15.483247] Bluetooth: hci0: Fseq BT Top: 00.00.00.00 [15.578712] Bluetooth: MGMT ver 1.22 [15.822682] Bluetooth: RFCOMM TTY layer initialized [15.822690] Bluetooth: RFCOMM socket layer initialized [15.822695] Bluetooth: RFCOMM ver 1.11 Signed-off-by: Kiran K --- drivers/bluetooth/btintel.c | 38 ++++++++++++++++++++++++++++++++++++- drivers/bluetooth/btintel.h | 3 +++ 2 files changed, 40 insertions(+), 1 deletion(-) diff --git a/drivers/bluetooth/btintel.c b/drivers/bluetooth/btintel.c index ed98bb867cff..00e98606cf02 100644 --- a/drivers/bluetooth/btintel.c +++ b/drivers/bluetooth/btintel.c @@ -521,6 +521,9 @@ static int btintel_version_info_tlv(struct hci_dev *hdev, version->min_fw_build_nn, version->min_fw_build_cw, 2000 + version->min_fw_build_yy);
