Derivatives for Microsoft Surface notebooks
These derivatives use the patches from the linux-surface repo.
Kernel
The kernel needs several patches to make it work correctly with some of the hardware on various Surface models, e.g. keyboard/trackpad, camera, wifi.
Not all hardware is fully supported, but the linux-surface feature matrix provides details on which devices are supported on which types of machine.
The kernel-specific derivations are under the kernel/
sub-directory.
In order to simplify maintenance of the Nix code, only the most-recent kernel patch-set is expected
to be maintained in this repo.
_NOTE:_Some built-in Kernel config items need to be set, that aren't set by default:
Firmware, Drivers and Support Tools
WiFi
For the Surface Go, please see the "Issues" sections below.
IPTS
IPTS is used on most of the Surface range, except for Surface Go and Surface Laptop 3 (AMD version).
Older kernels used specialised firmware which used a method that's no longer supported by the more-recent kernels.
Newer kernels use the kernel-space intel-precise-touch
driver and user-space ipstd
daemon.
The iptsd
daemon works with the intel-precise-touch
driver to convert raw touch data from the
kernel-space driver into events for the HID / input sub-system.

TLP daemon
TLP is known to cause problems on Surface unless correctly configured. See: https://github.com/linux-surface/linux-surface/blob/master/README.md
Wifi Firmware for Surface Go
On the Surface Go, the standard firmware from the official Linux Firmware repo has issues with the
ath10k
QCA6174 Wifi device.
You will see messages like "Can't ping firmware" TODO - Copy messages from console
The most effective fix to-date is to remove the board-2.bin
file or replace it with a copy of the
board.bin
file.
