Hi Guo, I've just tested with a recent -nightly here and it pass 100%. Could you please retest with latest -nightly?
I tested on byt with nightly latest: d2a1764437d8b4c30948704ff6c64e4bbfd1df7c(2015-01-20) case still failed, but output is a little different. ./kms_rotation_crc --run-subtest sprite-rotation IGT-Version: 1.9-g20d6e0f (x86_64) (Linux: 3.19.0-rc4_drm-intel-nightly_d2a176_20150120+ x86_64) (kms_rotation_crc:4460) CRITICAL: Test assertion failure function test_plane_rotation, file kms_rotation_crc.c:207: (kms_rotation_crc:4460) CRITICAL: Failed assertion: igt_crc_equal(&data->ref_crc, &crc_output) Subtest sprite-rotation: FAIL (0.331s)
