From a5beee65241d25ad20dd814668c975ba13a42615 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 5 Jul 2024 17:52:38 +0300 Subject: [PATCH] drm/i915/fbc: Extract intel_fbc_max_plane_size() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Extract intel_fbc_max_plane_size() from intel_fbc_plane_size_valid(). We'll have another use for this soon in determining how much stolen memory we'd like to keep reserved for FBC.
