Abysmal PATA IDE performance

Abysmal PATA IDE performance

[Stephen Clark]

Hi list,

I just purchased a VBI-Asus S96F laptop Intel 945GM &  ICH7, with a Core
2 Duo T560,0 2gb pc5400 memory.
  From checking around it appeared all the
hardware was well supported by linux - but I am having major problems.

  the disk which is a 7200rpm Hitachi travelmate pata drive transfers 
data at 1.xx
mb/sec
     according to hdparm. This same drive in my old laptop an HP n5430 
with a
     850 duron the rate was 12-14 mb/sec.

Attached are the output of lspci -vvv, dmesg and hdparm
Any insight would be greatly appreciated.

lspci -vvv:

Remove the drivers/ide stuff from you system and let libata (ata_piix)
manage the ICH7.  That should speed things up quite a bit.

Appears first and that's where the other driver has taken control of the
drives. I had the same issue on my thinkpad, getting rid of the whole
IDE stuff solved the problem (because the other drivers does no longer
grab the drive).

This ThinkWiki entry should apply to your laptop just as well, just
replace /dev/hda with /dev/hdc.

Probably ide0 is pure SATA, while ide1 has the PATA adapters (just a
guess).

Thank Bjorn,

I tried this and the kernel couldn't find the root volumegroup - so i 
got a kernel panic.
I am not sure on how to tell the system the volumegroup is now on sd? 
This is a
fc6 installation.

For reference you can also use ide0=noprobe ide1=noprobe and similar to
control this

Probably your drives are renamed.
Before you had (wild guess, look at your boot log messages):
- ata bus -> hdc,hdd
- sata -> sda (if you really have any sata bus...)

Now all hdX become sdX, and PATA is detected _before_ SATA, so you names
probaly became:
- ata via libata -> sda (HD), sr0 (CDROM)
- sata -> sdb.

So boot with root=/dev/sda. And don't forget to update lilo/grub config.
And /dev/cdrom links if udev doesn't.

Hope this helps.

PD: It would be very nice if libata had some parameter like 'sata_before_pata=1'
or the like...

on fedora this doesn't matter (due to mount-by-label)

the bigger problem I suspect is that the sata modules aren't part of the
initrd!

you can force the issue by adding

alias scsi_hostadapter1 ata_piix

to the /etc/modprobe.conf file, and then recreating the initrd
(see the mkinitrd tool, or just install the kernel rpm)

Thanks all.

Arjan, using combined_mode=libata and making a new ramdisk increased my 
xfer rate from 1.xx mb/sec to 28.xx mb/sec.

I am curious as to why my friends dell inspiron 8200 with a 1.8ghz p4 
and the same drive using the same drive with FC6 and the standard ide 
module gets 44 to 45 mb/sec.

now it is going to come down to how you measure this....

don't use hdparm, use something like tiobench (tiobench.sf.net);
another setting that might be different is that scsi normally turns the
write back cache off (safer for your data but slower) while IDE normally
leaves at at factory default (on for cheating on benchmarks).
For writes, this can easily explain the difference...

The figures are so similar to the problem I recently posted that you
 might want to give a shot at unloading ehci_hcd module, then try
 again getting performance numbers from the IDE disk. In my case
 unloading ehci_hcd boosts IDE performance from 20 to 40MB/s
 (but of course kills USB2 disk performance).

There is no cable the disk plugs directly into the MB.
How can I force this to udma 66 or higher - the ide driver accepted  
idex=ata66 to control this.

Also the specs for the laptop say it supports ide 100MBps (Ultra DMA 5).

This is your optical (CD/DVD) unit; I doubt that you can saturate that
link, even if your drive can do a sustained 16x transfer with a DVD it
will use only 21MBps. Your HD is using UDMA/100.

Forcing the interface to a higher speed may lead to CRC errors when
using the drive.

Hi Luca,

aren't the ata2.00: messages referring to my hard drive and the

ata2.01: ATAPI, max UDMA/33

You're right, I misparsed your log. Probably Arjan is right about the wiring.

Hi Luca,

The specs for the laptop say it supports ide 100MBps (Ultra DMA 5).

Well, the controller does support UDMA 5, maybe it's just marketing.
Or maybe autodetection just doesn't work.

The above is for ata2.00.

And, this for ata2.01.

PATA devices occupying the same channel literally share the cable, and 
the driver needs to configure PIO mode of both devices to the slowest of 
the two (PIO mode is always configured regardless of actual transfer 
mode).  UDMA mode doesn't save such restriction, so devices can be 
configured to its own maximum transfer mode.

libata, until recently, simply used the slowest max transfer mode for 
both PIO and UDMA modes (MWDMA too).  So, that's what's happening to 
you.  Your cdrom's max UDMA mode is UDMA/33, so libata is using it for 
both devices on the channel.  Recent kernels (2.6.19-rcX) don't have 
this restriction.  Give 2.6.19-rc5 a shot.

Hi Tejun,

Thanks for the info, I had started looking at the libata code but hadn't 
progressed very far.

Hi all,

using 2.6.19-rc5 did give me udma 100 for my harddrive and a xfer rate 
of 44mbps.

thanks to all who offered advice.
