[Intel-gfx] [PATCH 01/15] drm/i915: Check pipe source size when using skl+ scalers

2023-04-18 Thread Ville Syrjala
From: Ville Syrjälä The skl+ scalers only sample 12 bits of PIPESRC so we can't do any plane scaling at all when the pipe source size is >4k. Make sure the pipe source size is also below the scaler's src size limits. Might not be 100% accurate, but should at least be safe. We can refine the limi
