Thanks to kernel patches, pushed onto Linux 7.2 mainstream and [Gentoo overlay](https://github.com/miasvanklei/Gentoo-overlay), most of the previous features which this release lacked (stable suspend on GNOME, accelerometer sensor, dedicated video output, cameras) are now implemented. The project has diverged into [patched kernel](https://sayag.it/fedora-linux-surface-pro-12in/kernel-surface.git) + [libcamera](https://sayag.it/fedora-linux-surface-pro-12in/libcamera.git) builds with an [RPM repo](https://rpm.sayag.it/kernel-sp12in/) publicly available.

Trying a stable version (the latest is Fedora 44 at the time of writing this) is possible, but not tested for now. If you want to compile this image manually, **the build arch must be `aarch64`**. It means that if you are on an `amd64` machine, you would have to use aarch64 instructions emulation tools like `binfmt`. Unfortunately, such a tool will drastically increase the compilation time. @@ -34,29 +30,7 @@ To build this on Fedora Linux: []$ sudo ./kiwi-build --kiwi-file=Fedora.kiwi --image-type=iso --image-profile=Workstation-Live --output-dir ./outdir ``` -## Feature matrix - -| Hardware | State | Nuances | -| --- | --- | --- | -| Keyboard | ✓ | | -| Touchpad | ✓ | | -| Tablet Mode | ✓ | | -| Touchscreen | ✓ | | -| Pen | ✓ | Tested with Surface Slim Pen | -| WiFi | ✓ | 2.4/5 GHz networks | -| Bluetooth | ✓ | | -| Speakers | ✓ | | -| Buttons | ✓ | | -| Suspend | ✓ | `s2idle` tested | -| Hibernate | ? | | -| Sensors | ✓ | Accelerometer works, but light sensor outputs garbage, so adaptive brightness is disabled | -| Battery Status | ✓ | | -| Cameras | ✓ | Front camera -- overexposured areas tend to get green; back camera -- uncalibrated | -| GPU acceleration | ✓ | Video encoding/decoding driver is taken dynamically from a Windows partition | -| USB 3 | ✓ | Video passthrough on hubs (via HDMI) also tested and works | -| DisplayPort out | ✓ | Found issues with suspending while an external monitor is active, where the system freezes | - -## Compromises +## What is left out (for now) * Live CD has to run in RAM, so `rd.live.ram=1` is set for cmdline.
