PineNote Development/Building Kernel

WIP!!!

What I'm Doing

1. Clone mw's stuff and parse out his scripts
   1. Start clone_and_prepare_git.sh
      1. We can just run this as is. Note whatever dir we run it in will have smaeul's linux kernel cloned into it (as well as patches. aka make this a clean directory to work in)
      2. I recommend looking through the patches to see what they do. Worth noting that the patch mentioned in Dorian's notes for GPU is already here, in `rk3566-pinenote_dtsi.patch`
   2. compile.sh
      1. Run this in the same directory. I started at 12:32 (finished within 15 mins)
   3. install_to_pn.sh
      1. send dtb into `/boot/dtbs/rockchip/` (note that I don't have v1.2 yet this is new) `scp rk3566-pinenote-v1.2.dtb root@pinenote:/boot/dtbs/rockchip/`
      2. update extlinux.conf to point to this new dtb
      3. send over image to /boot
      4. send modules to overwrite what's in /lib/modules : `rsync --delete -avh --progress lib/modules/5.17.0-rc6-next-20220304-* root@pinenote:/lib/modules/`
         1. I didn't have rsync installed on pinenote (it needs to be on client and server). Installation failed because i had new dtb "existing in filesystem" so I moved it to /root for now.
   4. compile mesa
      1. get mesa from here: https://github.com/0cc4m/pinenote-misc/releases (I can't install since I am deving on debian, not arch).
      2. Try to run dpkg-buildpackage gives me an error saying it can't open debian/changelog. This is because I don't have the debian package, which can be obtained here (I think) : https://salsa.debian.org/xorg-team/lib/mesa/-/tree/mesa-22.1.3-1.
      3. Install devscripts, run `mk-build-deps --install --root-cmd sudo --remove` to install build dependencies, then run dpkg-buildpackage.
      4. This spat out a ton of files into ../ (but not libmutter-9-0_41.4-1_arm64.deb as indicated in the install script. Worse, I didn't cross compile, it's all amd64 deb! I'm so dumb because it comes prebuilt in 0cc4m's stuff: https://github.com/0cc4m/pinenote-misc/releases lol
      5. Send that stuff over to the pinenote!!
      6. Untar it and install the packages like this: https://wiki.archlinux.org/title/offline_installation_of_packages
2. At this point everything should be installed. Let's restart and see what happens.
   1. Kernel panic: https://pastebin.com/4Z0aJgHz
   2. Looking back to see if I missed anything. Mutter? Similar to mesa, but I actually have to build it. Build script has commands needed. Ah shit but I'm on debian, meaning I can only build for debian. I could do a chroot thing...but it's probably not mutter.
   3. Somehow I was booting the wrong kernel. I re-scp'd smaeul's kernel, confirmed md5's, and could boot.
3. But now networking is busted. Looking trhough `journalctl` for hints.
   1. https://matrix.to/#/!QtTzSRYMuozjbOQkzJ:matrix.org/$HdLaPUKxQr3F690EFNa0Qk0tm_k-72p8cX6ngObk_XQ?via=matrix.org&via=kde.org&via=tchncs.de
   2. Just rename those files and we'll boot, but still not display -- do I need modified mutter? It's X that's failing to start
4. Display doesn't work either
   1. Need to change lib/firmware/waveform.bin to lib/firmware/rockchip/ebc.wbf. This whole conversation is a lot of the same stuff i ran into: https://matrix.to/#/!QtTzSRYMuozjbOQkzJ:matrix.org/$hnt-F-5YkDfb5I4Ky_ENI7s2jqq4O5Aeo-y4dFCsp_0?via=matrix.org&via=kde.org&via=tchncs.de

1. Going to try switching to gnome?

https://wiki.ubuntu.com/LightDM#Changing_the_Default_Session

1. Try switching to wayland? Idk the other guy was getting this error with wayland and sway, I'm getting with X and kde. Maybe something else.

1. Look for sddm logs

Occam rescued me again!
