Your latest code from the rth7680/tci-next branch is twice as fast as my = code with BIOS boot and qemu-x86_64 on sparc64. That's great. With that code I don't get any BIOS output at all when running=20 qemu-i386. That's not so good. Did I test the correct branch? If yes, I could try the same test on=20 amd64 and arm64 hosts. Stefan
