… the patches and firmware binaries.

Add MS Surface Kernel patches from github.com/linux-surface/linux-surface

Add MS Surface Firmware from github.com/linux-surface/linux-surface

Add MS Surface Hardware config from github.com/linux-surface/linux-surface

Tie-together the Microsoft Surface .nix files

Set to use explicit version of Linux (5.4.7)

- Add the config for Linux 5.4.7

Add kernel 5.4.11

Add kernel 5.4.13

Remove unsupported patches

Revert to kernel 5.4.7 for now

- Problems initialising touchscreen & pen

Add kernel 5.4.15 and 5.4.16

Build kernel 5.4.16, instead

Add kernel 5.4.22

Update the patches for kernel 5.4

Placeholder for Linux kernel 5.5

Copy the IPTS kernel patch from the 5.5 dir to the 5.4 dir.

Conversation on https://gitter.im/linux-surface/community suggested this would
reenable IPTS on 5.4:

hpfr Blaž Hrastnik (Gitter): thanks for the mention. mexisme (Gitter) finally, someone who actually knows Nix and isn't just a config nerd writing proper NixOS Surface configs! I am stuck on 4.19 at the moment because IPTS is now a proper reverse-engineered kernel driver (https://github.com/linux-surface/intel-precise-touch) instead of just a blob package, and I haven't had time to look at how to package that for Nix. If you're on 5.5, are you just not using IPTS? Would love to help out on packaging that for NixOS
hpfr also, development conversations seem to happen more at #linux-surface on freenode, which you can connect to with matrix via https://matrix.to/#/!OXIGGPCpnzaNVeGtCA:matrix.org if you don't like IRC clients

hpfr Also, I'm not using jakeday's patches, I'm using the more recent ones from the linux-surface/linux-surface repo, but yeah, for 4.19, so they're a bit different from the 5.x patchsets. afaik 4.19 is still supported because it's the last LTS release that supports the "official" IPTS blob before Linux made changes that required reverse engineering a driver that didn't use GuC submission (I'm just quoting here, I have no idea what that is haha)

Blaž > now a proper reverse-engineered kernel driver
Should be similar to before, we just offer it as a patch
Blaž https://github.com/linux-surface/linux-surface/blob/master/patches/5.5/0007-ipts.patch
Blaž Anyway I'm keeping an eye out on your NixOS builds since I'm thinking about giving it a try

@matrixbot Feb 29 19:32
Blaž Currently running Arch but using nix as a way to manage development environments for various projects

@matrixbot Mar 01 10:41
hpfr Blaž: well shoot is that patch all that’s necessary for building in-tree? It does all the things the linux-surface/intel-precise-touch repo does?

Dorian Stoll @StollD Mar 01 12:56
Yes
Just adds all the files from the repo to drivers/input/touchscreen and adds the necessary glue to drivers/input/touchscreen/{Makefile, Kconfig}

@matrixbot Mar 02 09:13
hpfr Dorian Stoll (Gitter): oof. Could’ve been on 5.4+ all this time!

Move kernnel *.nix packages under their respective kernel dirs

Use lib.mkDefault

Update to kernel 5.4.24

Update to kernel 5.5.8

Typo

Drivers are modules by default

Revert to 5.4.24 until can fix the config failures

…ones

- Delete the derivatives for 5.5.8, 5.9.2 and 5.10.4
- Nix build for kernel 5.10.2
- Update the kernel config for 5.10.4

- NOTE: The file is left, due to an incoming PR to fix for ath10k firmware not
  loading correctly on Surface Go range.

…/fetch-patches

- This will be worked on independently, and hopefully added to nixpkgs, instead.
