[Cbe-oss-dev] kernel exception on ps3

[Martin Schreiber]

hi!

i got a kernel exception and hope that this mailing list is the right to send exception:

i used the recent ps3 kernel version (git clone
git://git.kernel.org/pub/scm/linux/kernel/git/geoff/ps3-linux.git) but
the same kernel exception also occures with the original kernel version
2.6.16.

the distribution is fc5

at the end of the email, you'll find the kernel exception.

the exception was produced about 30 percent with the uncommenting of the
following piece of code on spus.

        for (i = 0; i < SPU_NUMS; i++)
        {
                if (spe_data_block.spe_id == i)
                {
                        for (a = i+1; a < SPU_NUMS; a++)
                        {
                                send_to_spu(a, 600+spe_data_block.spe_id);      // send spu_id + 600 to other spu
                                read_from_mbox();                               // read pong from other spu
                        }
                }
                else
                {
                        if (spe_data_block.spe_id > i)
                        {
                                read_from_mbox();
                                send_to_spu(i, 600+spe_data_block.spe_id);      // send pong
                        }
                }
        }


the functions send_to_spu just writes to the according control_area of the other spu (via dma operations).

can i help you in another way?

ciao & thx,
  martin
