Installation
Make the following changes in the EFI setup application:
| EFI Config Option | Value |
|---|---|
| Secure Boot | Disabled |
| Linux Boot | Enabled |
 |
The Linux Boot option (In EFI BIOS: Config -> Linux -> Linux Boot) must be enabled, see pmaports!5027 for more info. |
Use pmbootstrap to build your own installation image, the regular procedure is:
$ pmbootstrap init
$ pmbootstrap install --fde
For this device, the most straight forward way to install pmOS to the local nvme disk, at least until ondev2 is ready, is to build a USB drive with a pmOS install, boot it, then use pmbootstrap to build/flash an image to the nvme disk. The process then looks something like this:
$ pmbootstrap install --disk /dev/<usb disk> --add pmbootstrap
# Boot the usb disk on the laptop
$ pmbootstrap init && pmbootstrap install --fde --disk /dev/nvme0n1
WWAN / Mobile Data
With pmaports!4718, mobile data should be working after you enable the FCC unlock script for the modem. The most straight forward way to do this is by just enabling all scripts by:
$ sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*
GPS
Some initial support for GPS seems to be working, though I haven't been able to get geoclue to use it as a source yet:
$ mmcli -m 0 --location-enable-gps-raw --location-enable-gps-nmea
successfully setup location gathering
$ watch mmcli -m 0 --location-get
It might be working fine on UIs that configure/start geoclue by default, that's TBD.
Camera
Camera is now supported with custom kernel branch with camss patches and custom libcamera. The Spectra DSP is not supported so the RAW images have to be processed on the CPU using soft IPA.
$ cam -l

Available cameras:
1: Internal front camera (/base/soc@0/cci@ac4c000/i2c-bus@1/camera@10)
$ qcam
The Black and White camera used for Facial Authentication (Windows Hello) is not yet supported.
Audio
Audio works out-of-the-box with the combination pipewire, pipewire-pulse and wireplumber.
There may be some audio artifacts, especially whilst pavucontrol is running.
Known issues
A list of known issues can be found in the pmaports repository
