Re: [9fans] Intel ICH7 AHCI
assuming my code isn't totally broken on your machine, it looks as if you have no mp table at all. so either your machine has no mp table or we are looking in the wrong place. since i'm a little unsure how this could be, my next step would be to boot linux with mp interrupts to troll dmesg for clues and compare with where we're looking. perhaps someone else has a better idea. in looking at the mp spec 1.4 again http://download.intel.com/design/archives/processors/pro/docs/24201606.pdf plan 9 seems to cover the cases on p. 38 in pc/archmp.c:/^mpsearch. i wonder if that else shouldn't be elided. another way for bios to go wrong here is to report the wrong amount of base memory. - erik

What we see, all the time, is that the mobo makers just barely understand these tables, and usually get them quite wrong. We've also seen cases where the MP table for one board was used, verbatim, on a very different board. Finally, the vendors are always willing to rewire bits of the board, but don't quite get around to updating the table. Short form: PC hardware is crap. ron

[9fans] Intel ICH7 AHCI
Have tried Plan9 on Intel D945PLrn mainboard P4 Dualcore and MP, Network and AHCI doesnt work out of the box. ok, i try to resolve AHCI first... the pci ids are 0x8086/0x27c0 for the SATA controller (82801GB) and i tried to add this to the match function as Tich in sdiahci.c, but this fails on: if (p->mem[Abar].bar == 0) continue; SATA mode is on [Enhanced] not [Legacy]. any ideas to progress further here? This machine also fails MP. I get mpintrenable() errors for any devices including the keyboard and then i end up on the boot prompt unable to type anything. mpintrenable: out of choices -1 -1 cinap
