** Description changed: [Impact] BRI (Bluetooth Radio Interface) traffic from CNVr to CNVi was found causing cross talk step errors to WiFi. Therefore, when WiFi/Bluetooth is turned on, the Bluetooth/WiFi may not work reliably. [Fix] Apply the patch https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/bluetooth/btintel.c?id=c707097a446ce3d284bc9f05736dc4701d2b8168 on noble-oem-6.11 [Test Plan] 1. Compile noble-oem-6.11 with config BT_INTEL_PCIE on - 2. Include ibt-0190-0291-iml.sfi, ibt-0190-0291.ddc, ibt-0190-0291.sfi in /lib/firmware/intel/ + 2. Include Bluetooth FWs ibt-0190-0291-iml.sfi, ibt-0190-0291.ddc, ibt-0190-0291.sfi in /lib/firmware/intel/ ( These FWs are not public yet. We're going to do SRU in the future once the FWs are landed on the upstream linux-firmrware) - 3. Boot the noble-oem-6.11 kernel - 4. Run "hcitool scan" + 3. Include WiFi FWs bz-b0-fm-c0-92.ucode in /lib/firmware/ + ( The same. These FWs are not public yet ) + 4. Boot the noble-oem-6.11 kernel + 5. Test WiFi functionality. [Where problems could occur] The patch makes use of UEFI variable. If the variable is somehow not shown in the ROM, there might be some error.
