I test the branch above. It still happens on GM45 when run following cases:
igt/kms_flip/blocking-wf_vblank
igt/kms_flip/flip-vs-absolute-wf_vblank
igt/kms_flip/flip-vs-blocking-wf-vblank
igt/kms_flip/flip-vs-wf_vblank
igt/kms_flip/plain-flip-fb-recreate
igt/kms_flip/plain-flip-ts-check
igt/kms_flip/wf_vblank-ts-check
run: ./kms_flip --run-subtest blocking-wf_vblank
Using monotonic timestamps
Beginning blocking-wf_vblank on crtc 3, connector 5
1280x800 60 1280 1296 1344 1415 800 801 804 816 0xa 0x48 69300
..inter-vblank ts jitter: 0s, 16779us</pre>
