I don't think x86 having USB was a mistake. PIIX4 (the "pc" machine) already had USB 1.0, Q35 (ICH9) had USB 2.0 too. Not emulating those automatically would be a mistake from the faithfulness PoV. If they wanted to have a bare board, the option of just adding a virt board variant with the bare minimum (PCIe and ACPI, like arm64 and riscv64 do) is a fine idea. (the same thing applies to other x86-but-not-the-others things like VGA, etc. worse for VGA, it's more or less required to be there for a PC-compatible board). -- Pedro -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
