[Intel-gfx] DP compliance failure due to dithering for 18bpp video pattern

2017-01-09 Thread Manasi Navare
Hi All, We are seeing CRC check failures in some of the 18bpp video pattern DP Compliance tests causing the tests to fail. On further investigation, it is rootcaused to dithering that the i915 driver enables in case of 18bpp pipe configuration that messes up the CRC and causes the test to fail. S
