DMA on kernel 2.6.10-gentoo-r7? [SOLVED]

Sargonmetal · Last edited by Sargonmetal on Tue Mar 15, 2005 9:24 am; edited 1 time in total

Hi,

when I try to turn on de DMA on my hda I get the following error message:

#hdparm -d1 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

my Host Bridge when I do an lspci is:
Host bridge: Intel Corporation 82865G/PE/P DRAM Controller/Host-Hub Interface (rev 02)

When I compiled the kernel I use (2.6.10-gentoo-r7) I set up the following line as "y":
CONFIG_BLK_DEV_PIIX=y

I got a PIV 3400 Ht processor and I don't know what else I can do to solve this.
I heard somewhere something about the syslog, but I don't know what is that. I am newbie on linux.

I would really appreciate any help :wink:

Here you have a part of my .config:

#

Yes, I am.
I'll try to recompile with the same .config as yours.
I will tell...

Thanks!

Sargonmetal · Posted: Sun Mar 06, 2005 1:26 pm Post subject:

I recompiled my kernel with that configuration and it still doesn't work...

I got only one hd and it's partitioned as:
hda1: win partition
hda2: /boot
hda3: /swap
hda4: /

I should turn on DMA with "hdparm -d1 /dev/hda", isn't it?

I hope someone could help... :wink:

Could you post the output of 'dmesg|grep IDE' and 'lspci'?

Here you have the kernel config for a machine with the same chipset.

http://gentoo-wiki.com/Fractoon's_dedicated_build_-_part_1

Your driver is not loading for any reason as dmesg output shows, untill it loads right you won't be able to use advanced features like power saving and ultra dma. Are you sure that you are running the right kernel image?

Sargonmetal · Posted: Sun Mar 06, 2005 3:26 pm Post subject:

Thanks, I'll try to recompile with those settings.
Anyway, I'm not sure if I'm getting the correct image of the kernel, how could I know it?
Sorry, as I said, I'm a newbie on linux...

I''ve followed every step of the kernel config from the link above and I still get the same error message when I try to turn dma on.
When I boot the computer I get two warnings telling me that my dma is off and fschk process could be very slow.
I don't know what else I can do... I am compiling and using the right kernel version, now I'm really sure about it.
Please, somebody help me! :roll:

Thanks!

i92guboj · Posted: Tue Mar 08, 2005 3:43 am Post subject:

Could you try the gentoo livecd and see if the dma is on?
If affirmative then the point is somewhere in your kernel config for sure (or maybe in the kernel version you choosed).

Sargonmetal · Posted: Wed Mar 09, 2005 10:18 pm Post subject:

Definetely is a configuration kernel problem: when I boot from a live CD I can do an hdparm an dmy dma is activated.

Any more ideas?

I really want to have my dma working!
Thanks!!

i92guboj · Posted: Fri Mar 11, 2005 6:40 pm Post subject:

One point to start would be to compare compare the output of mesg between the livecd kernel and yours, so you could figure what the differences are between them.
Your could also compare the configs, but I'm not sure if you can acces the config of the livecd kernel (if you can it would be thru the /proc/config.gz file, supposing that feature is enabled in the livecd kernel, with I doubt).

When I do "mesg" on the livecd I only get:

Sargonmetal · Posted: Sun Mar 13, 2005 7:26 pm Post subject:

I didn't know the name of dmesg. Now I think I'll remember it :wink:

Ok, I rebooted with live CD and I copied the .config and the output of dmesg.
With LiveCD the Hyper Threading is also activated, and I can turn on the dma so I've tried to compile my kernel with the .config from the liveCD but the same thing has happened: No DMA, no HT, no eth, no USB, no NTFS, ...
To compile I do:

i92guboj · Posted: Sun Mar 13, 2005 7:48 pm Post subject:

there should beno problem for that. i ca thik oly of on thing. is your /boot partition mouted whe you install the rcompild kernel? if it is't then you ar istallig it o a dead zoe. O the other hand maybe you are usig the wrong paths into grub.conf. Othrwise this is ot understandable.

(my ky is brokn)

Sargonmetal · Posted: Mon Mar 14, 2005 9:59 am Post subject:

YES! The boot partition was unmounted!

grgr
Now I understand almost everything.
But I still got some problems: when I mount my /boot it says that the device is full, while it is 32Mb and I'm only using 6 or 7Mb.

on fstab I use:
/dev/hda2 /boot reserf notail 0 1

Thank you very much.
I feel like the one tou talk about on your sign... "Cuanta estupidez en tan poco cerebro..."

At last, It all works now!
HT enabled, DMA enabled, NTFS, usb, everything!
wow.
My system works really fast!

I've had to boot with my / partition but everything is fine now. Great! Thank you very much, your help has been amazing.
I think I'm beggining to like linux hehe
See you around, take care!

Wow, I feel happy too! Count on me for everything you need (till my limited knowledge reachs, of course).
