From 3e4ea7421f45966c93c8cbe81569e8dc93a58b87 Mon Sep 17 00:00:00 2001 From: Mario Kleiner Date: Sun, 21 Nov 2010 10:59:02 -0500 Subject: drm/kms/radeon: Reorder vblank and pageflip interrupt handling. In the vblank irq handler, calls to actual vblank handling, or at least drm_handle_vblank(), need to happen before calls to radeon_crtc_handle_flip(). Reason: The high precision pageflip timestamping and some other pageflip optimizations will need the updated vblank count and timestamps for the current vblank interval. These are calculated in drm_handle_vblank(), therefore it must go first.
