[9fans] Intel ICH7 AHCI

[9fans] Intel ICH7 AHCI

[cinap_lenrek]

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

there's a reason for this check. :-)  if bios isn't setting up Abar, then
either you're chipset doesn't support ahci or it isn't configured for
ahci.  generally the options are Enhanced mode with Ahci enabled.
they're different for esb southbridges.

intel says that the 82801gb does not support ahci mode.
	http://www.intel.com/support/chipsets/imsm/sb/CS-020644.htm
ich7 should support your drives in *ata* mode.  you may need
to add the vid/did to sdata.c  you can double check with pci.
the device class/programming interface/subclass should be 01.06.01.
you can check for a device with the proper configuration with this
command:

	% pci|grep 'disk 01\.06\.01'

generally this means that your machine's mp table is broken.  you can add
	*nomp=1
to your plan9.ini file to get around this.  unfortunately, using mp interrupts
there's no easy way to replicate what this bios does in setting up the
interrupt routing on a modern machine.

i have 2 entries in pci for disk with class/interf/subclass of:

disk 01.01.8a
disk 01.01.8f

but no 01.06.01 entries.

then it's highly likely that your mp table is incorrect.  in bios there is often an
option for mp specification version or some such.  you want to set that to 1.4
if you have it.  unfortunately, i suspect this is not your problem.

i put a version of mp.c on sources (/n/sources/contrib/quanstro/mp.c) that
provides the file #P/mpirq which prints out the mp table irq assignments.
if you can figure out how to save this stuff automatically with mp irqs enabled,
this should have enough information to say for sure.

i feel your pain.  i have a new motherboard with some bad entries in the mp
table, too.

Not surprising. 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.

There is a lot of PPC-based Apple gear coming on the used equipment
market. Considering the tight control Apple placed on the hardware,
porting the MD kernel bits has many fewer moving targets. And the lack
of hardware documentation sucks equally between the two platforms.

That ought to be good news and I am pleased to hear it.  I presume,
but I have no experience, that there is already a growing performance
gap?  Yet you'd think something like Plan 9 would bridge that gap by
making more efficient use of the hardware (less cpu-devouring
eye-candy) and therefore would attract at least some developers.

The ways of this grave new world are so very mysterious...

Sure. The Apple hardware is leaping behind the latest and greatest of
the Intel/AMD world.

And Plan 9 doesn't need to be there, either.

I have a 1.x G4 GHz Mac Mini that can't realistically keep up with
Leopard (server). But it will make a kick ass Plan 9 CPU server.

My point is that it's easier to fight the static Apple hardware, with
it's absent hardware doc, than to fight the dynamic Intel/AMD
hardware, with its/their also missing doc. At least the obsolete Apple
gear is a non-moving target, so we stand a chance ... The x86 stuff
changes on an hourly basis, and cannot be kept up with :-(

We violently agree on this point.  There may be less agreement as to
how to port Plan 9 to such hardware: there seems to be a drift towards
virtualisation which of course eliminates any efficiencies (yes, I
know I'm exaggerating) contributed by Plan 9.

I think the philosophy (who said it first?) that something isn't
finished as long as there are features that can be removed - which
very clearly applies to Plan 9 - is being replaced by a culture where
Plan 9 is needed to squeeze the last teraflop out of the fastest
ultracomputing platform available at any time.  I'm not sure that even
a middle ground is possible, while it is a matter of faith that the
first philosophy will eventually triumph over the opposing culture.

Some, of course, do not see the conflict here at all.

PS: You did suggest originally that there was a similarity between the
lack of documentation for Apple hardware and that for the Intel
platform.  I am pleased that you corrected that impression, the two
are different for exactly the reason you suggested.

The bad news is that there is still a *lot* of Apple-specific hardware
which would need to be dealt with.  The PPC Macs used fairly common
graphics hardware, but the same cannot be said of disk controllers,
interrupt controllers, etc.

The reading-lamp style iMac, for example, would require support for
a "Uninorth" memory controller and PCI bridge, a "Pangea" I/O hub, a
"Keylargo" ATA controller, and so on.  Suspend/resume is vastly
different from the PC world (for better or worse).

i'm not casting aspersions.  i've had good luck with getting corrected
bios in the few times i've had trouble on server motherboards.  i
think the problem is that mp interrupts are hard and need to be
constructed at bios runtime to account for the topology of add in
cards and bridges.

here is no such option for me

added a function to boot/boot.c that reads #P/mpirq and prints it. opening
the file works, but read() returns 0.

i have serial console connected to the machine now so here are some dumps:

Re: [9fans] Intel ICH7 AHCI

[erik quanstrom]

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.

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

plan 9 seems to cover the cases on p. 38 in

Come on, folks, PPC Apple was around for how many years, and the
only port effort I know of was a university project that I'm pretty
sure never got anything released. Why do we not want to do anything
until obsolescence is guaranteed? I think I'll start a Zaurus port,
that platform has been dead long enough now. If you want to work on
a port, do sparc64, since you can still buy those machines.

I'd be very interested in a Zaurus port, although in my case it would
be the SL-C3200 that I would be cheifly interested in. I have been
porting a desktop linux distro to it but keep running into trouble,
particulaly with the complexities of gcc and other bloated stuff. I
guess porting a Linux distro to a machine designed for Linux is on a
different level to porting an operating system, but if I can help with
anything I'd like to.

 You can run OpenBSD on these machines:

I always thought that rio would look spectacular on an Apollo DN3500...
