It seems like instead of comparing two vma, you just need to compare the vma->pages against the parent obj->pages. Don't we already do that? We do check we can write through the vma and read it via the obj. That should be checking the pages do map correctly, and are also tiled correctly. And we do check partial vs object dma addresses. Adding this pass to igt_vma_partial() looks redundant as you have already established both vma point to the same obj->pages. -Chris _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
