Re: kernel init exception
Hi, David, Segher, Maybe it was caused by floating exception.I found that,system received a program check exception,the reason for it was REASON_ILLEGAL. I also use show_regs to print the NIP in exception,it seemed that ,this exception was caused by 'vmhaddshs' instruction in user mode of init process . Is vmhaddshs avaliable on e500mc? My cross compile tool is gcc-4.1.2-glibc-2.5.0 ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

My cross compile tool is gcc-4.1.2-glibc-2.5.0 This isn't vmhaddshs (which is an AltiVec instruction), but something else that also uses primary opcode 4. It sounds like your toolchain isn't set up correctly for e500mc. Segher ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

Re: kernel init exception
why there generated a signal 4 in init process? That's SIGILL; sounds like you compiled init with the wrong (sub-)arch or cpu flags. Segher ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
