Will simple-framebuffer be able to use that reserved region transparently? Or will it require a custom simple-framebuffer driver? Could we make simple-framebuffer support a part of this series? _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
