ATA/IDE: dmaproc error 14 testers wanted!

[Andre Hedrick]

If anyone is suffering from the dreaded "dmaproc error 14: unsupported"
error and want to test a code that could get you out of that deadlock
please speak up.

Basically this is an Intel 440BX PIIX4 issues, but the solution is global
and should work for all cases.

This isnt the same as "ide_dmaproc: chipset supported ide_dma_timeout
func only: 14" is it? This was on a PIIX4 w/ test11-pre5. I've since
upgraded to test11-pre7 and the problem hasn't surfaced again.

Interestingly enough, I get it on a VIA MVP3 with 2.2.18pre + bkz's patch.
Since it's eaten two filesystems by now, I'm not overly eager to play
with it again... On a second thought though, I'd rather play with it now
in a controlled environment, so feel free to send the patch my way.

If you want details, just ask.

Thanks,
Ion

It is on kernel.org and the README tells you what to do to enable the stub
in ide-dma.c  If it works let me know!

ATA-4, ATA-5 TCQ status

[Sasi Peter]

Hi!

I would like to ask if the tagged command queueing capability in the
decent ATA standards is utilized in the linux IDE driver (2.2 2.2ide
patches, or 2.4 maybe...)?

Another question, a little bit offtopic is if anybody on this list is able
to point me to some pci UltraATA controller card, which has more than 2
channels (more than 4 drives w/o cascade magic) (preferrably 6 or 8
channels)? If the exists one, I do not need no HW RAID or anything like
that... I only need a lot of channels, in only one PCI slot.
There have been a lot of rant around here, and why I am addressing Andre
personally too is that in that debate his stated, that because such cards
exist, IDE can fall into line with SCSI in drives possible / PCI slot.

Your help is very much appreciated,

I hope that is supposed to be 'recent', because with the current TCQ
implementation listed in the specs Linux might as well not support it :)
It's simply not worth it.

But seriously, how come?

I thought they just somewhat like copied the SCSI implementation...

PS: Anybody knowing about a multi (>2) channel UATA host adapter?

I wish they would have, and based it on atapi. But they didn't...
Basically it requires you to poll for completion of tags with
a service command.

Exactly, Jens has seen the ugly beast because I have worked on coding it.
I am working to get IBM to change the method of doing this to make it
sane, but its not now.

Ok, so anybody knows a multichannel adapter? At least 4 channels?
Andre? Where do I get one? Where does the ATA revolution start?

Andre,

      Where on kernel.org are you hiding the README and patch files you
mention?

It didn't help me :)

Axialys have a squid/socks/NFS server which therefore has a fair bit of
disk activity.

It died randomly a while ago, so I put a serial console on it and this
morning a coworker had to reboot it.

The last message was apparently the very same you are trying to prevent:
"hdg: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14"
(usual caveat about hand copied)

This was 2.2.17+ide (20000904)+RAID(2.2.17-A0).

This morning I updated to this patch and I tried to kill it just now.
It died :(
(That is with the 20001118 ide patch instead of the 20000904 one)

This time only with a "hdg: timeout waiting for DMA" with nothing
following it on the serial console.

It seems that
hdparm -t /dev/hde & hdparm -t /dev/hde & hdparm -t /dev/hde & hdparm -t
/dev/hde & hdparm -t /dev/hdg & hdparm -t /dev/hdg & hdparm -t /dev/hdg
& hdparm -t /dev/hdg
kills it in this way.  (That might be excessive but I'll get odd looks
is the proxy is down again because I'm testing exactly how many hdparms
it takes).

Let me know if there is anything I can test (in the evening/this weekend).
