Hi Lucas, we tested your patch on PHYTEC i.MX6Q phyCORE with 1GiB and 2GiB RAM variants. I can happily report that the previous issues with "command buffer outside valid memory window" are gone when using kernel's cmdline parameter cma=256M for example! If you want you can add: Tested-by: Primoz Fiser <primoz.fiser@xxxxxxxxx> Otherwise, thank you for prompt response and implemented fix. BR, Primoz _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
