From f20535ce1dd96003e76c958ffaa9c345483d2dfd Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Wed, 19 Jun 2024 23:45:51 +0200 Subject: [PATCH] drm/xe/vf: Don't apply tile workarounds if VF MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The VF drivers can't apply any workarounds as they don't have access to related registers. Since xe_wa_apply_tile_workarounds() function is not using RTP yet, we have to add early return.
