From 6ccf996a0dec1852dab94ad865f27b4904750e12 Mon Sep 17 00:00:00 2001 From: Mary Guillemard Date: Wed, 7 Oct 2026 16:30:15 +0200 Subject: [PATCH] drm/nouveau: Skip the Turing CE workaround object for non-GR channels This workaround is here for the old Gallium driver and predate async CE and NVDEC. Instead of only skipping it for NVDEC, let's only apply it in case of GR channels. This should make async CE work properly on Turing by stopping the assign of a GRCE.
