Bluetooth: btintel: Remove redundant (hdr->plen > 0) in btintel_recv_event()

2026-08-07T19:40:26+00:00

Drop the check since: - it is already implied by the existing (skb->len > HCI_EVENT_HDR_SIZE) - hdr->plen is then not used by the function at all Signed-off-by: Zijun Hu Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btintel: Fix diagnostics event detection

2026-08-07T19:40:26+00:00

For a diagnostics VSE, diagnostics_hdr[] sits at the start of the event payload, skb->data[2], but btintel_recv_event() wrongly guards its memcmp with @len, which is measured from skb->data[3] for the earlier INTEL_BOOTLOADER check. Fix by using (@len + 1) instead, which == (skb->len - HCI_EVENT_HDR_SIZE) exactly.

Bluetooth: btintel: Add Bluetooth SAR revision 2 support

2026-08-07T19:38:32+00:00

BRDS revision 2 introduces per-chain (Chain A and Chain B) TX power limits across five sub-bands (2.4G, 5.2G, 5.8/5.9G, 6G-low, 6G-high), replacing the single-chain per-modulation model of revisions 0 and 1. - Add btintel_set_sar_rev2() which sends the full Rev2 DDC sequence: 0x019e inc-power-mode enable flag (1 byte) 0x0311 2.4 GHz sub-band limits (2 bytes) 0x0312 5.2 GHz sub-band limits (2 bytes) 0x0313 5.8/5.9 GHz sub-band limits (2 bytes) 0x0314 5.8/5.9 GHz sub-band limits again (2 bytes, duplicate FW reg) 0x0315 6 GHz low sub-band limits (2 bytes) 0x0316 6 GHz high sub-band limits (2 bytes) followed by the SAR-init-complete command (0xfe25). logs from dmesg when BTSAR2 is enabled in Coreboot/BIOS: Bluetooth: hci0: BT SAR Rev2: revision=2 bt_sar_bios=1 inc_power_mode=1 Bluetooth: hci0: BT SAR Rev2 Chain A: 2g4=76 5g2=0 5g8_5g9=0 6g1=0 6g3=0 Bluetooth: hci0: BT SAR Rev2 Chain B: 2g4=102 5g2=0 5g8_5g9=0 6g1=0 6g3=0 Signed-off-by: Ravindra Signed-off-by: Kiran K Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btintel: Validate length before parsing diagnostics TLV

2026-07-28T20:13:12+00:00

btintel_diagnostics() accesses tlv->val[0] without first validating that the diagnostics VSE is long enough to contain that field, so may cause reading data beyond the received frame. Fix by validating the length before access. Fixes: af395330abed ("Bluetooth: btintel: Add Intel devcoredump support") Signed-off-by: Zijun Hu Signed-off-by: Luiz Augusto von Dentz

Bluetooth: btintel_pcie: Support Product level reset

2026-06-11T18:24:37+00:00

When driver encounters a TOP exception, ACPI methods will be called for Product level reset since Wifi and BT share the same TOP. BT driver will first reprobe the wifi driver and then reprobe BT.
