Different than kms_mmap_write_crc that captures the coherency issues within the scanout mapped buffer, this one is meant for test dma-buf mmap on !llc platforms mostly and provoke coherency bugs so we know where we need the sync ioctls. I tested this with !llc and llc platforms, BTY and IVY respectively.
