From 93f724675d9c47d48ea56d82843e162a12ac41b4 Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Mon, 30 Nov 2020 19:17:29 -0500 Subject: meta-agl-profile-graphical: add device dependency hook in weston-init Add a mechanism in the weston-init recipe to allow machine templates to trigger installation of a systemd drop-in that adds a DRM device dependency for the weston@.service unit. Also, tweak the qemux86-64 configuration to enable doing so against dev-dri-card0.device to avoid startup failures due to the slow i915 initialization on e.g. the UpSquared. This approach has been taken since it seems safer for now to only apply it for qemux86-64 than doing a blanket default that might then need to be over-ridden for vendor BSPs.
