Hi, Sorry for the noise but I am having trouble getting the latest kernel built for a PowerMac8600 with a 750GX processor card. If this is not an appropriate topic for the list please tell me (and hopefully point me in the correct direction).
I have narrowed the problem down to the compiler. YDL 4.0 is installed on the machine. The stock compiler is 3.3.3. That version can NOT build past 2.6.28. I built 3.4.6, (the latest 3 series I could find). It can NOT build later kernel versions either. It can build Firefox 2.0.0.15pre, including powerpc thin lock support. Running it now. I then tried 4.3.5. This will build the kernel. But the resulting kernel will NOT run. A firefox built with 4.3.5 also will not run. Or if it runs it crashes often (http://abcnews.com). What really puzzles me is I used the same basic compiler boot strapping (3.3.3 to build 3.4.6, 3.4.6 to build 4.3.5) on a GiGE. That machine is now running 2.6.36. The CFLAGS used were: "-O2 -mcpu=7450 -mmultiple -mstring" for the GiGE (dual 7455s). Substitute 750 for the 8600. Any suggestions would be appreciated. Thanks! kevin P.S.: Why does this program work: int main(int argc, char *argv[]) { unsigned int pvr; // asm("mfspr %0,22\n" asm("mfspr %0,287\n" :"=r" (pvr) ); printf("pvr is 0x%x\n",pvr); } >From what I have read, access to the pvr is restricted? strace does not show an illegal instruction trap for SPRN_PVR. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
