aarch64-laptops' support table ticks WiFi for this machine, so the path exists. Following their WiFi README got considerably further and then stopped somewhere useful to have documented. Two of the four services they list are in the kernel now (pd-mapper, qrtr-ns). The other two, rmtfs and tqftpserv, are packaged in Fedora and shipped disabled — tqftpserv was not even installed. Both are now in base.pkgs and enabled by stage2. Enabling them took qrtr-lookup from 19 registered services to 25; a working setup is said to show around 40. The step worth having written down: the modem does not read wlanmdsp.mbn from /lib/firmware. It asks tqftpserv for it over TFTP, from /lib/firmware/readonly/firmware/image/. Nothing reports this as an error — ath10k_snoc binds, registers a QMI client, and waits forever for a service that never registers. c630-firmware now places the file there, and creates the writable area the modem asks tqftpserv for. Where it stops: the modem boots and dies at "RF stuck in QLINK start state", about every 42 seconds, never reaching the point of requesting wlanmdsp. Three firmware pairings give three distinct failures, recorded in the doc — the _nm "no modem" variants, which are the obvious idea and would skip cellular RF entirely, turn out not to be signed for this device. The result that narrows it: aarch64-laptops' own wifi directory carries the qcdsp1v2850.mbn, qcdsp2850.mbn and wlanmdsp.mbn from the setup whose table ticks WiFi. All three differ from the WOA-Project copies. Installed here with the services running and wlanmdsp in the TFTP path, they produce the identical QLINK failure — so it is neither the firmware nor the userspace. What is left is the kernel: 5.x from 2019 there against 7.1.5 here, with both of their ath10k patches long since upstream. That points at a regression, and confirming it means a bisect rather than another file. Also record what is untried: the other eight driver versions (this machine's UEFI is from 2019 and the newest package may be the wrong vintage), mcfg_subsys_ext850.cab, and building board-2.bin from the C630's own bdwlan.* files.
