+## CODE GENERATION INSTRUCTIONS
+
+You are tasked with integrating patches into my kernel to make the tearing protocol work on Wayland with my intel B580. 
+
+## THINGS TO DO:
+
+Plan out how you're going to do the following. I will inspect your plan and then authorize it.
+
+- Custom build this MR: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3797
+
+- Fix KDE tearing on Intel Graphics using kernel patches for libdrm. Use these resources to research:
+    - https://bugs.kde.org/show_bug.cgi?id=520549
+    - https://gitlab.freedesktop.org/drm/xe/kernel/-/work_items/8597#note_3567675
+    - https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/13834 (this one has patches that supposedly fix the problem.)
+
+
+# Plan here:
+
+- [ ] 1. Record the current package and kernel baselines.
+  - Evaluate the locked versions of Mutter, GNOME Shell, libdrm, and the selected CachyOS kernel.
+  - Confirm that the Intel Arc B580 (`8086:e20b`) is using the `xe` driver.
+  - Save the current working kernel and NixOS generation as the rollback baseline.
+
+- [ ] 2. Pin all experimental upstream sources.
+  - Pin Mutter merge request !3797 to a specific commit instead of following its branch.
+  - Record the MR base commit and verify whether it is compatible with the Mutter version in the locked nixpkgs input.
+  - Identify the exact revisions of the Intel async-flip and `IN_FORMATS_ASYNC` kernel patches referenced by the i915 and Xe work items.
+  - Use fixed-output hashes for every fetched patch or source archive.
+
+- [ ] 3. Determine which Intel DRM patches are still required.
+  - Inspect the selected CachyOS kernel source for patches that have already been merged or backported.
+  - Select only the missing patches needed to expose async-capable formats and prevent unchanged or disabled planes from incorrectly rejecting an async atomic commit.
+  - Confirm that the selected changes affect the Intel display code shared by `xe` and `i915`, and therefore apply to the B580 even when the original report is filed under i915.
+  - Document the required patch order and each patch's upstream URL and revision.
+
+- [ ] 4. Add a dedicated, reversible Wayland-tearing overlay or module.
+  - Keep the experimental Mutter and kernel overrides together in a new, clearly named repository file.
+  - Scope the override to `drivebystation-nix` where practical.
+  - Provide a single enable switch or isolated import so the experiment can be disabled without editing generated hardware configuration.
+  - Preserve all unrelated existing worktree changes.
+
+- [ ] 5. Override Mutter with merge request !3797.
+  - Prefer applying the pinned MR commits to the nixpkgs Mutter derivation so nixpkgs build flags and dependency wiring are retained.
+  - If the patch series is incompatible, use the pinned MR source only after confirming its Mutter ABI matches the installed GNOME Shell.
+  - Verify that libdrm is at least version 2.4.120.
+  - Ensure GNOME Shell and the display-manager session reference the overridden Mutter rather than merely installing it alongside the stock package.
+  - Enable the experimental feature with `MUTTER_DEBUG_EXPERIMENTAL_FEATURES=tearing` in the session environment.
+
+- [ ] 6. Override the CachyOS kernel with the selected Intel DRM patches.
+  - Extend the existing `pkgs.cachyosKernels.linuxPackages-cachyos-latest` kernel derivation rather than replacing it with an unrelated kernel package set.
+  - Apply the pinned patches in their upstream dependency order.
+  - Verify that every patch applies cleanly to the exact CachyOS kernel source.
+  - Keep `boot.extraModulePackages` tied to the patched kernel package set so `r8125` and `v4l2loopback` are rebuilt against the correct kernel.
+  - Do not modify the generated `hardware-configuration.nix` beyond any unavoidable existing kernel selection; place the override in a maintained host module.
+
+- [ ] 7. Validate the Nix expressions without activating the system.
+  - Run formatting and syntax checks on every changed Nix file.
+  - Evaluate the complete `drivebystation-nix` configuration.
+  - Run `nix flake check` and resolve evaluation failures attributable to these changes.
+  - Confirm that all sources are pinned and reproducible and that no mutable branch names remain.
+
+- [ ] 8. Build each risky component independently.
+  - Build the overridden Mutter derivation.
+  - Build the patched kernel derivation.
+  - Build the matching `r8125` and `v4l2loopback` modules.
+  - Inspect the build logs for rejected patches, warnings related to async flips, and ABI mismatches.
+
+- [ ] 9. Build the complete NixOS system before switching.
+  - Build the `drivebystation-nix` toplevel without activating it.
+  - Verify that the closure contains the pinned patched Mutter and patched CachyOS kernel.
+  - Confirm that a previous known-good boot generation remains available.
+
+- [ ] 10. Activate the result safely.
+  - Use `nixos-rebuild boot` first so the new system is selected only after reboot.
+  - Reboot into the patched generation and verify the running kernel version and `xe` driver binding.
+  - If the display fails or the system is unstable, boot the previous generation and disable the experimental module.
+
+- [ ] 11. Verify the kernel DRM capabilities.
+  - Run `drm_info` and confirm atomic async-page-flip capability is reported.
+  - Confirm `IN_FORMATS_ASYNC` is populated for supported primary planes.
+  - Confirm its absence on the cursor plane is handled as expected rather than causing the entire commit to fail.
+  - Capture a DRM debug log while submitting tearing-enabled fullscreen frames.
+
+- [ ] 12. Test KDE Plasma tearing.
+  - Enable Plasma's "Allow in fullscreen windows" tearing setting.
+  - Run a fullscreen tearing-aware game or test client with frame rate above the monitor refresh rate.
+  - Confirm that KWin's async atomic commits no longer fail with `-EINVAL`.
+  - Confirm that the previous `cursor A: async flip not supported` and `plane 2A: async flip not supported` errors no longer occur for disabled or unchanged planes.
+  - Check cursor movement, fullscreen entry and exit, direct scanout, VRR enabled and disabled, and all connected monitors.
+
+- [ ] 13. Test GNOME Mutter tearing.
+  - Start a GNOME Wayland session and confirm the tearing-control protocol is advertised.
+  - Run `weston-simple-egl -v -f -t` or an equivalent tearing-aware client.
+  - Confirm that requested asynchronous flips are accepted and visibly tear when the frame rate exceeds the refresh rate.
+  - Confirm unsupported async commits fall back to synchronized presentation without breaking the session.
+  - Test cursor movement, fullscreen transitions, VRR, multiple monitors, and suspend/resume.
+
+- [ ] 14. Document results and removal criteria.
+  - Record the tested hardware, kernel, Mutter, GNOME Shell, Plasma, and libdrm versions.
+  - Record the exact patches used and the outcome of both compositor tests.
+  - Document how to disable the overrides and roll back to the previous generation.
+  - Note which upstream merge or kernel release will allow each local override to be removed.

+# NixOS configuration
+
+The default package set is NixOS 26.05. Home Manager and AAGL use their
+matching 26.05 release branches. `drivebystation-nix` uses the standard
+`pkgs.linuxPackages` kernel from stable, including matching external modules.
+
+## Packages from unstable
+
+`inputs.nixpkgs-unstable` is a separate package set, pinned in `flake.lock`.
+Select individual applications explicitly, as with Trilium and JetBrains
+Toolbox in the desktop host:
+
+```nix
+unstablePkgs.trilium-desktop
+```
+
+The host defines `unstablePkgs` by importing the separate input with
+`allowUnfree = true`. Use `pkgs.<name>` for stable packages. Unstable
+applications retain their own dependencies; the system package set stays on
+stable.
+
+Update the stable inputs and the application exceptions independently:
+
+```sh
+nix flake update nixpkgs home-manager aagl
+nix flake update nixpkgs-unstable
+```
+
+The existing Mutter tearing override remains experimental. Its compatibility
+and B580 graphics behavior require testing when changing the desktop stack.
+
+## Validate and boot
+
+```sh
+nix build .#nixosConfigurations.drivebystation-nix.config.system.build.toplevel --no-link
+sudo nixos-rebuild boot --flake .#drivebystation-nix
+```
+
+Only run the boot command after the build succeeds. Keep the previous working
+generation available in the boot menu, then test networking, graphics, and
+the webcam loopback after reboot. Git restores configuration sources; booting
+the previous generation restores the previous system closure.
+
+Whole-flake checks currently also evaluate an unfinished WSL host referencing
+the disabled `nixos-wsl` input. Validate the desktop target directly until that
+separate host configuration is repaired.
+
+## Migration validation (2026-10-17)
+
+The complete `drivebystation-nix` system built successfully without activation.
+Its closure contains Linux 6.18.56, patched Mutter 50.5, GNOME Shell 50.5,
+libdrm 2.4.133, r8125 9.016.01, and v4l2loopback 0.15.3. The explicit unstable
+applications are Trilium 0.106.0 and JetBrains Toolbox 3.8.1.88030.
+
+Nix syntax and Git whitespace checks pass. `nix flake check --no-build` stops
+at the existing WSL input error described above. The edited Nix files retain
+the repository's existing formatting; `nixpkgs-fmt --check` reports formatting
+differences, including on the original flake before migration.
+
+Boot, networking, B580 graphics, and tearing behavior still require runtime
+testing. The migration does not add Intel tearing kernel patches.
