Hi all, I'm playing with Debian on an Origin 200 (aka ip27 - 64-bit mips). The current setup in the mips64-linux world is 64bit kernel + 32bit userland. So, a mips64-linux kernel can be mostly run a mips32-linux userland out of the box. Unfortunately, this doesn't apply to strace, as this play with the 64bit kernel's stack (eg: struct pt_regs), which is different in mips32 and mips64. So, I guess the solution is to hack (it's ugly as hell already...) strace to detect and understand the 64 bit stack from a 32 bit userland? Cheers, Andrew
