@@ -51,6 +51,17 @@ For the Framework 13 laptops, there are common configuration modules available u
including some modules specific to AMD- or Intel-based laptops. By preference, there will already be a specialised
module for your model's configuration. Otherwise, it can be added alongside the existing modules.
## OS integration
`hardware.framework.enableKmod` enables the [community-created Framework kernel
module](https://github.com/DHowett/framework-laptop-kmod) which exposes EC functionality like battery charge limit,
privacy switches, and system LEDs as standard driver interfaces. This enables, for example, configuring the charge limit
using the KDE settings GUI. The option is enabled by default when NixOS `>= 24.05` and linux kernel version `>= 6.10`.
On AMD Framework 13 and 16, before kernel 6.10, additional kernel patches are required for the kernel module to function
properly. Manually setting `hardware.framework.enableKmod = true` will apply the patches, requiring a kernel
recompilation.
