Assembles a ready-to-write disk image via Gitea Actions. Mainline has carried sdm850-lenovo-yoga-c630.dts since 5.5 and Fedora ships it in kernel-core, so unlike aarch64-laptops/build there is no kernel or GRUB to compile — what is left is producing an image that boots on firmware which hands Linux no device tree. The build runs in an aarch64 container under qemu-user and builds filesystems from directory trees with mke2fs -d and mcopy rather than mounting loop devices, so it works on runners that will not hand out /dev/loop-control. A kernel-install hook writes the devicetree line into each BLS entry; without it the first `dnf update kernel` would produce an unbootable system.

# Pull the model-specific Qualcomm blobs off this machine's Windows partition.

# Fedora ships everything for the C630 that Qualcomm allows to be redistributed
|
|
# — Adreno 630 (graphics) and ath10k WCN3990 (WiFi/Bluetooth) both work out of
|
|
# the box. What it cannot ship is the per-model signed firmware: the ADSP, the
|
|
# compute DSP, and the display/UEFI blob. Those are signed against this
|
|
# machine's own keys and live only in its Windows install.
|
|
#
|
|
# Without them you lose audio, the sensor hub (lid switch, accelerometer,
|
|
# auto-rotate) and hardware video decode. Everything else still works.

Done. Reboot to pick up the new firmware.

If qcom-firmware-extract could not find the Windows partition, mount it by hand
|
|
and point the tool at it:
|
|
|
|
sudo mkdir -p /mnt/windows
|
|
sudo mount /dev/disk/by-partlabel/Windows /mnt/windows # adjust as needed
|
|
sudo qcom-firmware-extract --windows-dir /mnt/windows
|
|
|
|
See docs/firmware.md in the c630 repo for the full file list and the manual
|
|
fallback if the tool does not recognise this model.
