Bluetooth: btintel: Fixe build regression

2024-03-06T22:26:10Z

This fixes the following build regression: drivers-bluetooth-btintel.c-btintel_read_version()-warn: passing-zero-to-PTR_ERR Fixes: b79e04091010 ("Bluetooth: btintel: Fix null ptr deref in btintel_read_version") Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btintel: Print Firmware Sequencer information

2024-03-06T22:25:33Z

Firmware sequencer (FSEQ) is a common code shared across Bluetooth and Wifi. Printing FSEQ will help to debug if there is any mismatch between Bluetooth and Wifi FSEQ. Signed-off-by: Kiran K Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btintel: Fix null ptr deref in btintel_read_version

2024-03-06T22:22:39Z

If hci_cmd_sync_complete() is triggered and skb is NULL, then hdev->req_skb is NULL, which will cause this issue. Reported-and-tested-by: syzbot+830d9e3fa61968246abd@syzkaller.appspotmail.com Signed-off-by: Edward Adam Davis Signed-off-by: Luiz Augusto von Dentz

Bluetooth: HCI: Introduce HCI_QUIRK_BROKEN_LE_CODED

2023-08-24T19:23:46Z

This introduces HCI_QUIRK_BROKEN_LE_CODED which is used to indicate that LE Coded PHY shall not be used, it is then set for some Intel models that claim to support it but when used causes many problems.

Added support for the new command opcode FE0B (HCI Intel PPAG Enable). btmon log: < HCI Command: Intel PPAG Enable (0x3f|0x020b) plen 4 Enable: 0x00000002 > HCI Event: Command Complete (0x0e) plen 4 Intel PPAG Enable (0x3f|0x020b) ncmd 1 Status: Success (0x00) Signed-off-by: Seema Sreemantha Signed-off-by: Lokendra Singh Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btusb: Move btusb_recv_event_intel to btintel

2023-08-11T18:51:53Z

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

2023-08-11T18:39:19Z

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

2023-04-24T04:59:02Z

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.
