Ahh - looks totally unrelated to the Altera platform so hopefully that isn't an issue. Apparently a lot of the PCIe implementations are based off the same underlying IP but without details its hard to check. I assume everything runs fine directly when not virtualised? Without a patched kernel on the AVA you would see corruption for X11 systems (although not Wayland). e.g.: https://gitlab.freedesktop.org/mesa/mesa/-/issues/9100 If you are happy your Arm can drive the AMD GPU ok from the host system you should focus on verifying the page locking is working as intended for the guests. -- Alex Bennée Virtualisation Tech Lead @ Linaro
