toshiba ide - ide dma setting

Hi.

I have a problem to allow DMA setting to my harddisk. I have Toshiba Satellite 320CDT laptop.

I found this question in letter's archive:
http://search.luky.org/linux-kernel.2003/msg35013.html

And the answer:
http://www.ussg.iu.edu/hypermail/linux/kernel/0306.0/0308.html

This is part of my dmesg from 2.4.26 kernel:
.........
Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
hda: TOSHIBA MK4006MAV, ATA DISK drive
hdc: CD-220EA, ATAPI CD/DVD-ROM drive

ide1 at 0x170-0x177,0x376 on irq 15
hda: attached ide-disk driver.
hda: host protected area => 1
hda: 8007552 sectors (4100 MB), CHS=7944/16/63
hdc: attached ide-cdrom driver.

Uniform CD-ROM driver Revision: 3.12
Partition check:
hda: [PTBL] [993/128/63] hda1 hda2 hda3 hda4
............

I know that is problem with bridge used for ide handle. I tried a lot of kernels:

Please tell me with patch will solve my problem for 2.6.10 kernel or what can I do for enabling DMA?

Another question:
In my bios I can choose two variant for my IDE:
* Standard IDE
* Enhanced IDE
Which should I choose?
I tried both and I dont's see any difference.

Sorry if my english is poor.

[ Okay, now I see what is the problem. :-) ]

Have you tried "Generic PCI IDE Chipset Support" ?

I thing that you are about:
generic / default IDE chipset support (kernel 2.6.10) ? Probably in 2.4 series the name was as you quoted. Yes. This option was compiled in kernel.

All kernels were compiled with setting all chipsets. I cared about set all of options responsible for IDE. All IDE drivers was compiled into kernel (not modules).

Part of my last config (2.6.10):

I think that the solution of my problem is here:
http://marc.theaimsgroup.com/?l=linux-ide&m=109967556605057&w=2
and here is your response:
http://marc.theaimsgroup.com/?l=linux-ide&m=109969178814722&w=2

"AFAICS this option allows users to use generic code for unknown/unsupported devices which can result in unpredictable results (hangs, data corruptions)." BZ

So I tried to apply this patch to 2.6.10rc1 kernel but there was a problem to compile it. I couldn't compile even clean 2.6.10rc1 without this patch.
I analised this patch and changed manualy drivers/ide/pci/generic.c
drivers/ide/pci/generic.h
from vanilla 2.6.10.
And ... nothing happend. The kernel was compiled cleanly without errors, but this didn't solve my problem.

Any suggestion?

Marcin Kuk

No...

...but you have it.

output of lspci command would be also helpful

This patch is in Alan's -ac tree.

Just get the latest patch for 2.6.10 from:
http://kernel.org/pub/linux/kernel/people/alan/linux-2.6/2.6.10/

As I remember I tried kernel applied by this patch.
This was the first thing that I made after vanilla kernel. I will try for sure again, but keep in mind that without DMA it is horribly long.
Haha can you imagine what I felt when updatetedb for slocate was runned at first time? Believe me I would like solve this problem as soon as possible.

Marcin Kuk

Bad news :-(.

Now I am working with my new compiled 2..6.10ac12 kernel. I can't enable DMA setting.

My system: Slackware 10

Marcin Kuk

Hi.

That's me again.
I don't know if you remember my problem so I remind.
What can I try to do for enabling DMA in my Toshiba Satellite 320CDT laptop. Any ideas, suggestions?
I will be thankful.
