It is on my roadmap. But the 64-bit kernel I tried didn't seem to boot. Also it would be nice if CONFIG_COMPAT could be disabled. > Dave Anglin is currently working on adding 64-bit userspace support > to gcc/glibc (dynamic loader), but that takes some time. > In the meantime a 64-bit nolibc would be cool for testing. Nice. Do you have instructions to run the 64-bit kernel in QEMU? Is qemu-user support planned? Thomas
