Yoga ALARM

Arch Linux ARM package build files for the Lenovo Yoga C630 / Snapdragon 850 (sdm845) platform.

The repository builds a small local pacman repository under packages/repo. It includes the Yoga kernel package, firmware package, and userspace Qualcomm services used by this device.

Packages

Package sources live under packages/:

• linux-yoga - Yoga C630 kernel package.
• firmware-lenovo-yoga-c630 - device firmware package.
• alsa-ucm-conf-yoga-c630 - Yoga C630 ALSA UCM routing and WirePlumber format fixes.
• pd-mapper-git - Qualcomm protection-domain mapper.
• qmic-git - Qualcomm IPC helper tooling.
• qrtr-git - Qualcomm QRTR tooling.
• tqftpserv-git - Qualcomm TFTP server.

Built packages and the pacman repository database are placed in:

packages/repo

Build

Build packages from the host using Docker:

scripts/run-docker-build.sh

The Docker build runs an ARM64 Arch Linux environment and writes package artifacts into packages/repo.

The build script currently controls which packages are built in:

scripts/build-packages.sh

Use The Repository

The package repository is consumed from the packages-latest GitHub release. Import and locally trust the package signing key on the target system:

curl -LO https://github.com/rigoorozco/yoga-alarm/releases/download/packages-latest/yoga-alarm-packaging.pub
sudo pacman-key --add yoga-alarm-packaging.pub
sudo pacman-key --lsign-key 041A82E390EAD451

Then add this to /etc/pacman.conf:

[yoga-alarm]
SigLevel = Required DatabaseOptional
Server = https://github.com/rigoorozco/yoga-alarm/releases/download/packages-latest

Then sync and install packages:

sudo pacman -Sy
sudo pacman -S linux-yoga firmware-lenovo-yoga-c630 alsa-ucm-conf-yoga-c630

After installing the audio fix, log out and back in or restart the user audio services:

systemctl --user restart wireplumber pipewire pipewire-pulse

Package Signing

Package archives in packages/repo can be signed after they are built:

scripts/sign-packages.sh --key 041A82E390EAD451

Export the public key file that users import with pacman-key:

gpg --armor --export 041A82E390EAD451 > yoga-alarm-packaging.pub

Only publish the exported public key. Do not publish ~/.gnupg, secret-key exports, or files created with gpg --export-secret-keys.

Notes

• Packages are built for aarch64.
• The repository database is named yoga-alarm.
• Repository database signatures are optional; package signatures are required by the documented pacman configuration.
