hello all! linux now works quite nicely, also uclibc port has been improved. i am now able to compile busybox with many userspace applications. due to improved toolchain (Scott patches) i was also able to remove all workarounds for toolchain bugs from linux kernel. right now i'm working on making more linux userspace applications work and ironing any kernel/toolchain/uclibc/simulator bugs. what follows is capture of linux running in a simulator. it took ~150 milion instructions to get this far (now i know i really need more powerful computer). linux is also beeing tested in silicon implementation of OpenRISC processor http://www.opencores.org/projects/or1k/Silicon and it works as expected. (simulator is constantly updated to be as accurate as possible). i will update you on any new/interesting developments. best regards, p. Copying Linux... Ok, booting the kernel.

Hi Matjaz!



Are these new version (linux, uclib and gcc) already updated in the cvs?

Greetings,
alex

no not yet. i'm going to import everything once we have agreed
on new compiler. (there are some workarounds needed in linux to work
with present compilers and i just want to make everything clean in cvs)

before we ci the new cvs i'd just want to remove the need to have 64-bit
values in aligned registers. i don't want any confusion so i'll do it all
at once.
