Huum, makes sense now.
But I guess would be better to initialize the start coordinate for each data->pos.
Like if running POS_TOP_LEFT, would be better to set initial cur to POS_BOTTOM_RIGHT values.

enabled != active.
Call 'igt_assert(psr_wait_entry(data->debugfs_fd, PSR_MODE_2));' before or even better between each commit moving the plane.
