2026-06-11Bluetooth: btintel_pcie: Load IOSF debug regs by controller variantSai Teja Aluvala
Load the IOSF DBGC base address based on the controller hardware variant when reading DRAM buffers during a trace dump. Scorpius Peak family controllers (SCP/SCP2/SCP2F) use a different DBGC base address (0xf0d5d500) than Blazar family controllers (BZRI/BZRIW, 0xf3800300).

2026-06-11Bluetooth: btintel_pcie: Add support for smart trigger dumpKiran K
Based on the debug configuration, firmware can raise MSI-X interrupt with firmware trigger cause bit set on specific events like Disconnection, Connection Timeout, Page Timeout etc. Upon receiving an MSI-X interrupt with the firmware trigger cause bit set, the driver performs the following actions: 1. Reads Device Memory: Retrieves data from the device memory, constructs an HCI diagnostic event, and sends it to the monitor. This event includes details about the trigger, such as connection timeout or page timeout. 2. Dumps Device Coredump: Generates a coredump containing firmware traces for further analysis. The coredump can be retrieved using: $ cat /sys/class/devcoredump/devcd*/data > /tmp/btintel_coredump.bin HCI traces: = Vendor Diagnostic (len 12) a5 a5 a5 a5 01 03 00 23 00 01 00 00 Signed-off-by: Kiran K <kiran.k@intel.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

2024-11-14Bluetooth: btintel_pcie: Add handshake between driver and firmwareKiran K
The following handshake mechanism needs be followed after firmware download is completed to bring the firmware to running state. After firmware fragments of Operational image are downloaded and secure sends result of the image succeeds, 1. Driver sends HCI Intel reset with boot option #1 to switch FW image. 2. FW sends Alive GP[0] MSIx 3. Driver enables data path (doorbell 0x460 for RBDs, etc...) 4. Driver gets Bootup event from firmware 5. Driver performs D0 entry to device (WRITE to IPC_Sleep_Control =0x0) 6. FW sends Alive GP[0] MSIx 7. Device host interface is fully set for BT protocol stack operation. 8. Driver may optionally get debug event with ID 0x97 which can be dropped For Intermediate loadger image, all the above steps are applicable expcept #5 and #6. On HCI_OP_RESET, firmware raises alive interrupt. Driver needs to wait for it before passing control over to bluetooth stack.

The feature takes into account the actual antenna gain, and increases output power values, which results in a performance improvement. After firmware download is completed, driver reads from ACPI table and configures PPAG as required. ACPI table entry for PPAG is defined as below.

Once the device is in SW RFKILL state, it can only accept HCI_Reset to exit from the SW RFKILL state. This patch checks the quirk for broken LED and sends the HCI_Reset before sending the HCI_Intel_Read_Version command.

2021-08-05Bluetooth: btintel: Fix the LED is not turning off immediatelyTedd Ho-Jeong An
Some platforms have an issue with BT LED when the interface is down or BT radio is turned off, which takes 5 seconds to BT LED goes off. This command turns off the BT LED immediately. This patch sends the Intel vendor command to turn off the LED. Signed-off-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2021-08-05Bluetooth: btintel: Fix the first HCI command not work with ROM deviceTedd Ho-Jeong An
The some legacy ROM controllers have a bug with the first HCI command sent to it returning number of completed commands as zero, which would stall the command processing in the Bluetooth core. As a workaround, send HCI Rest command first which will reset the controller to fix the issue. Signed-off-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2021-08-05Bluetooth: btintel: Add combined setup and shutdown functionsTedd Ho-Jeong An
There are multiple setup and shutdown functions for Intel device and the setup function to be used is depends on the USB PID/VID, which makes difficult to maintain the code and increases the code size. This patch adds combined setup and shutdown functions to provide a single entry point for all Intel devices and choose the setup functions based on the information read with HCI_Intel_Read_Version command. Starting from TyP device, the command and response parameters for HCI_Intel_Read_Version command are changed even though OCF remains same. However, the legacy devices still can handle the command without error even if it has a extra parameter, so to simplify the flow, the new command format is used to read the version information for both legacy and new (tlv based) format. Also, it also adds a routine to setup the hdev callbacks in btintel. Signed-off-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2020-10-30Bluetooth: btintel: Replace zero-length array with flexible-array memberGustavo A. R. Silva
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].
