No, but since it's 1/3 of a complete patch set, I don't care to investigate the
intermediate result either.


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 qemu-i386. That's not so good.

Did I test the correct branch? If yes, I could try the same test on amd64 and arm64 hosts.
