[9fans] sata working on cd kernel, but not after install?

[Ben Calvert]

when running from the CD, my sata drives are detected and I can
install onto them.  when i try to boot from one of them, it can't find
the drive.

if i install onto an ata drive, i can boot, but sdE and sdF don't show
up in /dev

is this a case of the cd kernel being out of sync from the installed
one?

geoff has probablly fixed things for you today.  this line from sdata.c
added recently should support your nvidia controller
		case (0x00E3<<16)|0x10DE:	/* nVidia nForce2 250 SATA */
thanks, geoff.

i've got no idea about your 3ware controller.  from the
subclass code, it's a custom interface.

would this be in the updates from this morning?  i've just pulled
everything and rebooted, but i still only see sdC0 and sdD0...

don't care about that one anyway.  software raid == bad

to the best of my knowledge, no one has ever built a bit
of hardware that does all the things raid needs to do in
hardware.  i don't think anyone has even implemented the
entire hot path in hardware.  there's always a processor and
firmware.  the only argument is where it runs.

fair enough.  and as soon as one completed the hardware, and shipped
it, one would find that it was buggy and be unable to patch it, as it
was in hardware :)

I'm still having the same two problems after pulling geoff's updates:

in vmware ( fusion ) i get the "aux/vga: vgactlw: <linear 0x3e80000
0x0>: unknown vmware id 0740

error, and on my physical machine, my sata disks are still not showing
up

... even though all of these things work during installation from the
cd. ( i'm using a cd from a couple of days ago )

the following diff enables dma on this controller and has yet to blow
anything up.

echo dma on>/dev/sdXX/ctl doesn't turn dma on?

And I was so proud of myself.

Is this documented somewhere? the only reference to dma i found was in
the Supported PC Hardware page of the wiki, which suggests editing
data.c.

Speaking of the wiki, I notice that the instructions on the Acme Wiki
Instructions are not working?  There are some links on the site that
are broken, ( e.g. the installation notes link on the http://plan9.bell-labs.com/plan9/
  page points to http://plan9.bell-labs.com/wiki/plan9/installation_instructions/
  instead of http://www.plan9.bell-labs.com/wiki/plan9/Installation_instructions
  ) and I thought to help fix that

In any case, my system is now mostly idle and is no longer generating
tens of thousands of interrupts per second.
