From 4e1e26f1b09398fad93ba24be816368714bede7c Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Tue, 14 Jul 2015 16:29:13 -0300 Subject: [PATCH] drm/i915: don't disable FBC for pipe A when flipping pipe B Use the appropriate call. I know there's a discussion about whether we need this call here at all, but removing the call means we'll only update FBC after we get the page flip IRQ. So the user may only see the new frame a little after it should. Let's wait just a little bit more before removing this call since we can rely in the HW tracking for accurate flips.
