From 4bc6745df2dbc315dc5a29a8b79020a74bd8fdd9 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 5 Mar 2024 10:47:29 +0200 Subject: [PATCH] drm/i915: Disable planes more atomically during modesets MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Follow in the footsteps of commit c610e841f19d ("drm/i915: Do plane/etc. updates more atomically across pipes") and do the plane disables back to back for all pipes also when we are disabling pipes. This should provide for a potentially more atomic user experience, which might be especially nice when using joiner or tiled displays.
