IT8212 in 2.6.9-ac6 no raid 0 or raid 1

IT8212 in 2.6.9-ac6 no raid 0 or raid 1

[Robert Toole]

Alan, thanks for your work on the ITE8212 controllers.

Just tried your ac-6 patch for 2.6.9 on my embedded Raid controller. 
with the controller set up in normal (No raid mode) everything is good.

When I try raid 0 or 1, I get the INVALID GEOMETRY: 0 PHYSICAL HEADS? 
error, and the raid device is not accessible after boot.

Maybe I am just missing something silly in the .config?

I put what I think is relevant below, I would be happy to provide extra 
info as requested and help test patches etc...

Please cc me as I am not subscribed to the list.

Thanks in advance,

RAID needs -ac7 which I'll post tomorrow. Bartlomiej found a bug in the
-ac7 draft code when I submitted it for 2.6.10rc merging so it slipped a
day.

I installed -ac7 yesterday, and have been testing for 24 hours now with 
no problems. (It's way better than the scsi hack from ITE) There is just 
one thing, the driver did not enable DMA by default, needless to say 
performance was awful. I turned it on with hdparm and everything appears 
ok. Is this by design due to the experimental nature of the driver?

I am testing by copying about 400 mb of files from one folder to another 
on the raid array, over and over again. Is there a howto or test 
software out there for better method to *really* hammer on the driver?

Thanks,
Robert Toole

Ah that is a bug. Please send me more info - drive info, hdparm etc.

Just use it. Its been hammered a lot as part of my testing but the
moment other people just use it it breaks ;)

Ok here is what I have:

Gigabyte GA-7M400 Pro 2 (Rev 2.0) integrated IT8212 controller:

- Bios for the controller: 1.14, Firmware ver 02093030

Info from the setup utility:

- RAID resources
   Ch0 Interrupt:B I/P port: 00009410
   Ch1 Interrupt:B I/P port: 00009C10

- Auto rebuild is on

- The controller sets up the drives with UDMA6 on post.

Hard drive info:

2 x Maxtor 40GB 7200rpm ATA133 Model: 6E040L0 set up in a raid 1 config.

Right after I boot I do: hdparm -tT /dev/hde

/dev/hde:
  Timing cached reads:   1620 MB in  2.00 seconds = 809.31 MB/sec
  Timing buffered disk reads:    6 MB in  3.40 seconds =   1.77 MB/sec

hdparm /dev/hde

/dev/hde:
  multcount    =  0 (off)
  IO_support   =  0 (default 16-bit)
  unmaskirq    =  0 (off)
  using_dma    =  0 (off)
  keepsettings =  0 (off)
  readonly     =  0 (off)
  readahead    = 256 (on)
  geometry     = 4998/255/63, sectors = 41110141952, start = 0

hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hde

- it does not like the multicount setting, saying HDIO_SET_MULTCOUNT 
failed: invalid argument. (I don't really understand this, and don't 
think I need it, I picked it up from the gentoo howto.) the drives work 
great anyway :) I included the error because it might tell you something.

/dev/hde:
  setting fs readahead to 64
  setting multcount to 16
  setting unmaskirq to 1 (on)
  setting using_dma to 1 (on)
  setting drive read-lookahead to 1 (on)
  multcount    =  0 (off)
  unmaskirq    =  1 (on)
  using_dma    =  1 (on)
  readahead    = 64 (on)

hdparm -tT /dev/hde

/dev/hde:
  Timing cached reads:   1604 MB in  2.00 seconds = 801.72 MB/sec
  Timing buffered disk reads:  158 MB in  3.00 seconds =  52.59 MB/sec

For comparison, here is hdparm from /dev/hda which is attached to the 
nforce2 controller:

/dev/hda:
  Timing cached reads:   1624 MB in  2.00 seconds = 810.10 MB/sec
  Timing buffered disk reads:  150 MB in  3.01 seconds =  49.81 MB/sec

/dev/hda:
  multcount    = 16 (on)
  IO_support   =  1 (32-bit)
  unmaskirq    =  1 (on)
  using_dma    =  1 (on)
  keepsettings =  0 (off)
  readonly     =  0 (off)
  readahead    = 256 (on)
  geometry     = 16383/255/63, sectors = 40059321856, start = 0

It works fantastic once you enable dma

Whoops! The Bios is 1.41, not 1.14, sorry about that.

Thats correct - in raid mode the controller emulates an IDE controller
but is doing all the work (its actually hardware raid) and it doesn't
support multisector PIO stuff (not that this matters for DMA). The -u1
and -d1 are the two that matter

No this makes sense - I need to adjust the fixup handling slightly. I
fix up the IT8212 misreporting of DMA a little too late for the generic
code to decide to turn DMA on.
