hdparm can't enable dma with ich6m

rob666 · 09-04-2005, 04:29 PM

Hi,
I can't get dma enable on my dvd or hard disk. I'll consentrate this post on the harddrive because I figure once that works the dvd should work too. Now I have ICH6-M so it's actually supposed to support SATA, but the hard disk is ide.
first here's the output for hdparm -d1 /dev/sda1:

/dev/sda1:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Inappropriate ioctl for device

Here's my hdparm -i /dev/sda1 output

PHP Code:



/dev/sda1:

 Model=WDC WD800VE-75HD09.0, FwRev=09.0, SerialNo=
 Config={ }
 RawCHS=9729/255/63, TrkSize=0, SectSize=0, ECCbytes=0
 BuffType=unknown, BuffSize=0kB, MaxMultSect=0

 IORDY=no
 PIO modes:  pio0
 AdvancedPM=no

 * signifies the current active mode

It makes no indication that dma is even available however in dmesg | grep ata says that I have udma/133:

PHP Code:

ata1: status=0x51 { DriveReady SeekComplete Error }
ata1: error=0x04 { DriveStatusError }

the last error messages show up at boot as:

This is appartently a problem related to which modules are directly in the kernel and which one's are added afterwards. I don't know what this has to do with hdparm, but I'm guessing this is confusion hdparm. here is my lsmod output:

I've read some suggestions that I edit my /etc/modules file to load ata_piix and piix before the ide modules, but that hasn't worked.

I have kernel 2.6.10-5-686 running as 2.6.11 didnt work, so I'm not sure what modules ubuntu has built in there or what's added later. I assume dma is supported though as ubuntu suggests running hdparm -d1 on it's wiki.

I did find an apparent fix for this, but it involves building a new kernel. I don't feel very comfortable doing that since I screwed up a few already and the patch seems iffy. On top of that I don't really want to since I'd have to reinstall the graphic driver, wireless, sound and I wouldn't know how to built it exactly like the 686 version as there's only a 2.6.10 linux-source available.
linuxquestions.org/questions/history/340897
Lastly in my bios dma is set to auto, 32 bit is on. This is an asus z63a laptop and there aren't any options in the bios for the sata controller.
Anyway hope this post wasn't too long. Would appreciate any help.

If the disk is recognised as sata then this is normal. The dma is enabled but hdparm cannot set it because it is using ide ioctls.

The ata_piix driver is sata support for intel chipsets. (google search shows the drive is ide like you said)

run "hdparm -t /dev/sda" and post the output
Is the disk slow ?

rob666 · 09-05-2005, 01:18 PM

Hi
Here's my output for hdparm -t /dev/sda.
It's not too shabby, but I'd like to do some capturing and editing in dv format.

/dev/sda:
Timing buffered disk reads: 54 MB in 3.08 seconds = 17.51 MB/sec

Thanks for the reply.

rob666 · 09-05-2005, 02:23 PM

If I turn dma off with hdparm I get just as fast or if not a faster read of my hard drive than with it on!?!

Code:

rob@ubuntu:~$ sudo hdparm -d0 /dev/sda

/dev/sda:
 setting using_dma to 0 (off)
 HDIO_SET_DMA failed: Inappropriate ioctl for device
rob@ubuntu:~$ sudo hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:   90 MB in  3.03 seconds =  29.66 MB/sec
rob@ubuntu:~$ sudo hdparm -d1  /dev/sda

/dev/sda:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Inappropriate ioctl for device
rob@ubuntu:~$ sudo hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:   90 MB in  3.02 seconds =  29.81 MB/sec

If I understand what ioctls are correctly then I assume that if hdparm can't understand the hard disks ioctl it won't be able to control it. You could be right and dma is turned on some other way, or hdparm could be communicate with the harddisk in some rudementary way to turn on dma. Anyways here's hdparm /dev/sda, again to show it's not seeing that dma is turned on eventhough it just said it has turned it on.

Code:

/dev/sda:
 IO_support   =  0 (default 16-bit)
 readonly     =  0 (off)
 readahead    = 256 (on)
 geometry     = 9729/255/63, sectors = 80026361856, start = 0

Any way I'd really appreciate some more help to figure this one out.

As you see "HDIO_SET_DMA" failed. that is why you get the same result.
None of the commands "-d0" and "-d1" worked so you get the same.
30mb/sec is not very much.

Here's my output.

Code:

bash-3.00# hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:  170 MB in  3.01 seconds =  56.44 MB/sec

But, my disk is a 7200rpm sata desktop disk and your is a 5400rpm mobile hard disk, so maybe 30mb/sec is good.
I don't know how much does it get.

rob666 · 09-05-2005, 05:00 PM

Hi,
first off thanks for your input. I sure wish I would have gotten a sata drive too, but my laptop merchant advised against it. I found the following infos on the Western Digital Scorpio WD800V. This on the western digital website:

Transfer Rates
Buffer To Disk 421 Mbits/s (Max)
Buffer to Host (EIDE)
- Mode 5 Ultra ATA 100.0 MB/s
- Mode 4 Ultra ATA 66.6 MB/s
- Mode 2 Ultra ATA 33.3 MB/s
- Mode 4 PIO 16.6 MB/s
- Mode 2 multi-word DMA 16.6 MB/s

And this on cnet:

External / Internal Data Transfer Rate

ata Transfer Rate 100 MBps
External / Internal Data Transfer Rate:Internal Data Rate 52.6 MBps

Not sure what it mean and how it compares with what tested on hdparm. But hdparm seems to detect less.
