From 85a040bc9049dd168d5e79a1fa9d2da87e6e52dc Mon Sep 17 00:00:00 2001 From: Ashutosh Dixit Date: Thu, 19 May 2022 09:57:30 +0100 Subject: drm/i915: Introduce has_media_ratio_mode Media ratio mode (the ability for media IP to work at a different frequency from the GT) is available for a subset of dGfx platforms supporting GuC/SLPC. Introduce 'has_media_ratio_mode' flag in intel_device_info to identify these platforms and set it for XEHPSDV and DG2/ATS-M.
