Hi All,
as exclaimed in the Subject, I have now a 64bit Kernel booting
into /bin/sash on my IP28. Unfortunately, it crashes immediately
at the first keystroke.
In Detail, I used the following software:
- Current binutils CVS with my patch to partially support
mips64-linux (It's barely enough to build a Kernel).
- An GCC CVS snapshot of 2001-05-01 (later ones do not work)
with a patch from Ralf to support R10000 and an patch to
make it bootstrap for mips64-linux.
- Current linux oss CVS with a large patch for mips64 support.
I got with this:
- A real 64bit Kernel image without linker crashes etc.
No objcopy tricks, the Kernel is loaded at 0xa800000000000000.
- The Kernel uses new-style interrupts (the old ones were confusing
and crashed on my first attempts to use the serial console).
- The sgiseeq ethernet works, it gets the bootp parameters and
allows nfs-mounting the rootfs.
- The serial console seems to work also, as good as it can be
predicted with an immediatly crashing init-shell.
