[Intel-gfx] [PATCH igt] kms_plane_crc: Add a basic CRC based planes test ala. ksm_cursor_crc
ville.syrjala at linux.intel.com

Mon Jan 13 16:10:51 CET 2014
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
The test uses a 64x64 plane and moves it aroudn the screen corners
like kms_cursor_crc does with cursors. We alternate between black
and white framebuffers on both the crtc and plane in question.
On platforms that have scalable sprites, we also test if the crc
behaves as expected when we scale up the 64x64 image to cover the
entire screen.
