|
|
Greetings to all!
I'm just wondering- whats the status on HPPA SMP support?
My K-Class machine is nearing completion now, and sofar I've got 6 200mhz Procs in it w/4GB RAM (still need drives & a power cable though). I was just wondering, will I be able to use SMP on this rig? It is a K570.
Cheers! |

HPPA SMP in general works.
I did not find a success story for a K570, neither did I find someone stating that it does not work. It should be definitely worth it to try out. |

Seems to work just fine over here.
Got the box running, sofar its pretty stable.
My only concern is that SMP doesn't seem as fast as I thought it would be- with 6*200mhz Procs and MAKEOPTS="-j7", GCC took over 7 hours to build. In particular when it runs the configure scripts (checking for <bla bla>...), it is painfully slow.
I'm not sure if its actually working or what- compiling the kernel took about the same time as on a Uniprocessor kernel.
The kernel does indeed find the 6 Procs, /proc/cpuinfo shows 6x 200mhz 899/K570 CPU's, and PDC shows all 6 units as functional. The box is sucking up the amperes and generating some heat, so they are doing something... |

Could you please post your kernel .config file, I have a K260 SMP which gives me kernel panic when using my own kernel, but it works fine with the UP kernel shipped with the Gentoo CD. I guess I must have done something wrong...
Thanks

I will post it as soon as I get the box back up (its down right now, since I'm setting up DistCC to speed things up).
Just out of curiousity- where is it panicing in the bootup? Is it right before the Login appears (Agetty)? |

Hard to see, and I still haven´t figured out how to scroll back on my HP console.
However it is somewhere after scanning the SCSI buses and detectin the disk partitions, I´m afraid that is not to exact but .... |

I built a new kernel, 2.6.15-rc6-pa1, and now it boots up just fine with the same kernel config. |
