    Question Compiling error when compiling link kernel 3.3 for MPC83XX


    Hi,

    I am trying to build kernel for my powerpc MPC83XX board.
    Starting linux kernel version 3.3.0, I am getting this build error;

    AS arch/powerpc/kernel/idle_6xx.o
    arch/powerpc/kernel/idle_6xx.S: Assembler messages:
    arch/powerpc/kernel/idle_6xx.S:135: Error: Unrecognized opcode: `dssall'
    make[1]: *** [arch/powerpc/kernel/idle_6xx.o] Error 1

    I am not sure if it sources isuue or bintools issue
    what was changed in this version?

    Thanks

    This stuff is over my skill set in Linux. I don't build kernels or use Mac computers, so just posting the info in case it helps you.

    Thanks

    It turned out that this issue still exist in binutils 2.22


    If it is such a known bug (since 2004) how come nobody fixed it? How come since version 3.3, kernel can't be compiled for powerpc?

    My guess is that ppc is not a priority with developers in the fact that they are not prolific through out the population that is linux users. Like I say. Just a guess on my part. Even at Puppy Forums. Which has a bunch of free lance developers. People have tried to port Puppy linux to ppc but soon lost interest due to lack of interest from the rest of the members at Murga.

    I guess it is kinda like trying to shoe horn a harley motor into a moped. Not a big demand for it. Most Mac owners are happy to just run a out dated version of Mac OS on their old PPCs. Just my take on proprietary hardware though.

    Hi,

    I found the problem
    it concern to "Altivec" commands, the solution is simple just check in "altivec" in menu config.
    But there is another issue - they added support to "currituck" board which is based powerpc 44x, that has diffrenet instructions set
    and It fails also on unknown op code.
    Is there is standard way to cause kernel to compile code only to desirable board?
    How can apply a bug to "kernel.org" or to denx ?

    Thanks
