BugLink: https://bugs.launchpad.net/bugs/1954938 [Impact] WCN685x hw2.1 takes additional/updated firmware for both WiFi and Bluetooth function. ath11k_pci 0000:71:00.0: BAR 0: assigned [mem 0xa6000000-0xa61fffff 64bit] ath11k_pci 0000:71:00.0: enabling device (0000 -> 0002) ath11k_pci 0000:71:00.0: Unsupported WCN6855 SOC hardware version: 18 17 ath11k_pci: probe of 0000:71:00.0 failed with error -95 [Fix] WCN685x hw2.1 currently shares most WiFi firmware with hw2.0 except for the directory path and a board-2.bin. For Bluetooth, updated revision of qca/nvm_usb_00130201_gf* from mainline are neccessary for Focal. Jammy has all of them already. For kernel, many of the prerequisite works have been committed for hw2.0 in bug 1945154, 1952215 and 1958850. Currently, while WiFi 6G will be turned off for the lack of userspace support, the only fix necessary is to correct read mask of version info register. ath11k 6G band lives in mainline v5.16 and was backported to oem-5.14 in bug 1939528, so only oem-5.14 has to be reverted. [Test Case] WiFi and Bluetooth devices should be up and running, pass basic operations. $ lspci -nnk|grep -A3 Network 0000:71:00.0 Network controller [0280]: Qualcomm Device [17cb:1103] (rev 01) Subsystem: Foxconn International, Inc. Device [105b:e0ce] Kernel driver in use: ath11k_pci Kernel modules: ath11k_pci $ lsusb Bus 003 Device 004: ID 0489:e0e3 Foxconn / Hon Hai [Where problems could occur] At the time being, WCN685x WiFi 6G support will be turnef off deliberately due to the lack of full support in the userspace management tools. [Other Info] While this is a new hardware model from OEM program, it's only nominated for Focal oem-5.14 kernel and the coming LTS Jammy.
