From 3107fc63078bf1c3df235eabf6609155fd1c239c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 7 Nov 2025 20:11:24 +0200 Subject: [PATCH] drm/i915: Use mode_config->cursor_width for cursor DDB allocation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Replace the hardcoded 256 with mode_config->cursor_width when doing the cursor DDB allocation. Currently 256 is correct for all SKL+, but this might change in the future. One less place to change should that happen.
