# Changes to the microsoft/surface top-level
 | 
						|
 | 
						|
## Overview
 | 
						|
 | 
						|
When I (@mexisme) created the microsoft/surface profile, there weren't that many differences between
 | 
						|
the various models of Surface.
 | 
						|
 | 
						|
I had just acquired a Surface Go 1, and it was mostly safe to enable all the options for all the
 | 
						|
models, and they would fail gracefully enough that we could mostly ignore warnings or errors.
 | 
						|
 | 
						|
Now, however --- as-of 2023-01-10 --- we have a much wider variety of chipsets, incl. models with
 | 
						|
some of the newer AMD CPUs, and this is breaking small things in annoying ways for more people.
 | 
						|
 | 
						|
## Changes
 | 
						|
 | 
						|
### Model Specialisations
 | 
						|
 | 
						|
In keeping with the broader structure of "nixos-hardware", I've also changed the structure of the
 | 
						|
microsoft/surface profile to make it easier for people to specialise for their hardware.
 | 
						|
 | 
						|
Any code or modules that are specialised for a Surface model now have their own directory under this
 | 
						|
top-level.
 | 
						|
 | 
						|
E.g. I am moving the Surface Go specialisations into `surface-go/`, and there may be further
 | 
						|
specialisations like `surface-go-3/`.
 | 
						|
 | 
						|
### "Common" modules
 | 
						|
 | 
						|
All the "common" modules that were once in the top-level of the microsoft/surface profile have moved
 | 
						|
under the `common/` directory.
 | 
						|
 | 
						|
Tools / services that are shared among several models are now extracted to their own module under
 | 
						|
`common/` and imported by `common/default.nix`.
 | 
						|
These new "common" modules now have an `enable` option, which is `false` by default.
 | 
						|
 | 
						|
### "Deprecated Behaviour" module
 | 
						|
 | 
						|
The original `./default.nix` module has been replaced by a new `deprecated/` module, which replicates the
 | 
						|
original behaviour.
 | 
						|
 | 
						|
The new `./default.nix` will load the new `deprecated/` module, but will also pop-up a warning asking users
 | 
						|
to update how they use the microsoft/surface profile from now on.
 | 
						|
This warning will probably change to a fail assertion at some point in the future.
 | 
						|
 | 
						|
## Adding a new Model Specialisation
 | 
						|
 | 
						|
This hasn't been finalised, partly as I now only have access to a Surface Go 1, these days, so I'm
 | 
						|
maybe not the best custodian of this code any longer.
 | 
						|
 | 
						|
However, hopefully the (imminent) `surface-go/` module is a reasonable exmample, and we should be
 | 
						|
able to gather more examples for more model specialisations over time.
