8.igt/kms_cursor_crc/cursor-64x64-random
9.igt/kms_cursor_crc/cursor-64x64-sliding
Result:
Above 9 cases pass on both BSW and BYT.

---------------------------- 
1. igt/kms_cursor_crc/cursor-256x256-onscreen
2. igt/kms_cursor_crc/cursor-256x256-random
3. igt/kms_cursor_crc/cursor-256x256-sliding2.

Result:
These three tests fail on the BSW, but pass on BYT.
