Interesting. 'target' does not play any role in the test other than
serving as the baseline for comparison at the very end of an iteration.

The only thing that comes to my mind is that cursor gets progressively
slower. Can you check that, as I don't have ICL at hands?

We do nloops=50 of iterations for cursor-vs-flip. You can turn the
igt_assert_f() to an igt_debug() and see how the shared[0], which
has the number of performed updates, changes over the course
of execution.

Thanks!
