** Description changed: [ Impact ] Currently, the built-in NVM is loaded because Qualcomm hasn't released correct NVM files until recently. This results in poor bluetooth performance. Firmware finally landed in upstream linux-firmware: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/commit/?id=77a11ffc5a0aaaadc870793d02f6c6781ee9f598 Required kernel patch: https://lore.kernel.org/all/20241116-x13s_wcn6855_fix-v2-1-c08c298d5...@quicinc.com/ [ Test Plan ] Boot and check that the new firmware is loaded and that bluetooth connections can be established. dmesg: - [ 6.159831] Bluetooth: hci0: QCA Downloading qca/hpbtfw21.tlv + [ 13.306736] Bluetooth: hci0: QCA Downloading qca/hpbtfw21.tlv + [ 13.962393] Bluetooth: hci0: QCA Downloading qca/hpnv21.b8c [ Where Problems Could Occur ] Kernel patch specific to QCA bluetooth driver. New firmware that is only loaded on specific Qualcomm HW. Should not affect any other users.
