+Subject: [PATCH 1/2] fix(displayport): allow detach when sink is unplugged
+
+The HPD check in dpPreModeset() rejects detach-only requests after unplug. This skips DP library cleanup while NVKMS advances its head bookkeeping, leaving stale attached groups that can block subsequent link training.
+
+Allow detach-only requests when HPD is low. Reject requests with an attachment target on any selected head, preserving the connector/discovery guards and forced-connected and dynamic-mux exceptions.

+# NVIDIA ARM DisplayPort detach fix
+
+ARM-only edge package carrying Martin Stark's pending
+[NVIDIA PR #1359](https://github.com/NVIDIA/open-gpu-kernel-modules/pull/1359)
+to fix DisplayPort disconnect cleanup in 615.71.09. Based on
+[Arch's DKMS recipe](https://gitlab.archlinux.org/archlinux/packaging/packages/nvidia-utils/-/commit/f9ae10b379f8b1d0832ec92bca1c12072aa123e9).
+
+Requires `[omarchy]` before `[extra]` and matching `nvidia-utils=615.71.09`.
+Update both NVIDIA packages together; automatic version tracking is disabled.
+
+Remove this recipe and the published package/database entry once a fixed
+Arch Linux ARM driver is validated. A stale package in the earlier repository
+can block driver updates.
