Bluetooth: btusb: Move btusb_recv_event_intel to btintel

2023-08-11T18:51:53+00:00

btusb_recv_event_intel is specific to Intel controllers therefore it shall be placed inside btintel.c so btusb don't have a mix of vendor specific code with the generic parts. Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btintel: Add support to reset bluetooth via ACPI DSM

2023-08-11T18:39:19+00:00

New Intel platforms supports reset of Bluetooth device via ACPI DSM methods. The legacy reset mechanism via GPIO will be deprecated in future. This patch checks the platform support for reset methods and if supported uses the same instead of legacy GPIO toggling method. ACPI firmware supports two types of reset method based on NIC card. (Discrete or Integrated). 1. VSEC Type - Vendor Specific Extended Capability. Here BT_EN and BT_IF_SELECT lines are driven by a register in PCH cluster. This interface is supported on discrete BT solution. 2. WDISABLE2 - In this soluton, W_DISABLE2 pin in M.2 is connected to physical GPIO from PCH. The DSM interface shall toggle this to recover from error. Signed-off-by: Kiran K Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btintel: Add Intel devcoredump support

2023-04-24T04:59:02+00:00

Intercept debug exception events from the controller and put them into a devcoredump using hci devcoredump APIs. The debug exception contains data in a TLV format and it will be parsed in userspace.

Bluetooth: btintel: Set Per Platform Antenna Gain(PPAG)

2023-02-09T22:20:04+00:00

Antenna gain is defined as the antenna’s ability to increase the Tx power in a given direction. Intel is certifying its products with fixed reference antenna peak gain values (3/5dBi). 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. Name (PPAG, Package (0x02) { 0x00000001, Package (0x02) { 0x00000012, /* Bluetooth Domain */ 0x00000001 /* 1 - Enable PPAG, 0 - Disable PPAG */ } }) btmon log: < HCI Command: Intel Configure Per Platform Antenna Gain (0x3f|0x0219) plen 12 Mcc: 0x00000000 Selector: Enable Delta: 0x00000000 > HCI Event: Command Complete (0x0e) plen 4 Intel Configure Per Platform Antenna Gain (0x3f|0x0219) ncmd 1 Status: Success (0x00) Signed-off-by: Kiran K Signed-off-by: Seema Sreemantha Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btintel: Fix broken LED quirk for legacy ROM devices

2022-01-07T07:29:21+00:00

This patch fixes the broken LED quirk for Intel legacy ROM devices. To fix the LED issue that doesn't turn off immediately, the host sends the SW RFKILL command while shutting down the interface and it puts the devices in SW RFKILL state. 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. The affected legacy ROM devices are - 8087:07dc - 8087:0a2a - 8087:0aa7 Fixes: ffcba827c0a1d ("Bluetooth: btintel: Fix the LED is not turning off immediately") Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann
