I've expanded the set of working tests so: x86 host, Intel GPU x86/kvm Trixie guest + latest mesa - works aarch64/tcg buildroot guest - works Aarch64 host, AMD GPU x86/tcg Trixies guest + latest mesa - works aarch64/kvm buildroot guest - works As the Aarch64 HW I'm testing on (AVA Devbox) needs additional patches on top of Sean's series to deal with the busted Altra PCI which I provide here: https://git.linaro.org/people/alex.bennee/linux.git/log/?h=review/pfn-references-v12-with-altra-tweaks Anyway I'll re-state: Tested-by: Alex Bennée <alex.ben...@linaro.org> And I think this series is ready to merge once the tree re-opens. -- Alex Bennée Virtualisation Tech Lead @ Linaro
