From 3d25802e3ba7c82457b5c12bbfeefe391d8a333e Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Tue, 1 Jul 2008 12:32:52 -0700 Subject: DRM/i915: only use tiled blits on 965+ When scheduled swaps occur, we need to blit between front & back buffers. If the buffers are tiled, we need to set the appropriate XY_SRC_COPY tile bit, but only on 965 chips, since it will cause corruption on pre-965 (e.g. 945). Bug reported by and fix tested by Tomas Janousek .

Newer hardware that has HPET to emulate the legacy RTC device gets this value wrong since after it sets the rate, it returns before setting the variable used to report the IRQ rate back to users of the device -- so the set rate and the reported rate get out of sync.
