Subject: [PATCH 01/10] drm/i915/vrr: Use crtc_vsync_start/end for computing vrr.vsync_start/end
Date: Thu, 16 Oct 2025 11:24:05 +0530	[thread overview]
Message-ID: <20251016055415.2101347-2-ankit.k.nautiyal@intel.com> (raw)
In-Reply-To: <20251016055415.2101347-1-ankit.k.nautiyal@intel.com>

Use adjusted_mode->crtc_vsync_start/end instead of
adjusted_mode->vsync_start while computing vrr.vsync_start/end.
For most modes, these are same but for 3D/stereo modes the
crtc_vsync_start is different than vsync_start.
