From 11f813227295b884b263e266c8efa5b7b139bba5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ma=C3=ADra=20Canal?= Date: Sat, 30 May 2026 16:58:20 -0300 Subject: [PATCH] Revert "drm/v3d: Increase the autosuspend delay" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit 3341dd2bc43865b6424d95623065aff51470c15d. After #7400, this commit is no longer needed. After further analysis, the 100ms autosuspend delay was only ever a workaround: shorter delays caused more frequent runtime suspend/resume cycles on the BCM2711, which exposed the cache and MMU coherency bugs as random GPU hangs. With those hangs resolved, the inflated delay is no longer necessary. Reduce it from 100ms to 50ms so the GPU power domain can be released sooner once the GPU goes idle.
