AcerTM4152LMi - cannot enable DMA

Hi all,
I'm trying to install Slackware 10.1 on my Acer laptop, but I'm not able to set DMA on the hard disk. I've been recompiling kernel 2.6.12.2 for 2 days enabling/disabling all chipsets support.
lspci output is
...
00:1f.2 IDE interface: Intel Corp.: Unknown device 2653 (rev 04)
...

Finally yesterday I booted with Dyne:bolic which identified my IDE controller as SATA:

00:1f.2 IDE interface: Intel Corp. 82801FBM (ICH6M) SATA Controller (rev 04)

So I googled a bit finding a guy with the same chipset in http://www.meltin.net/hacks/linux/t43.html and here .config file flags suggested:

ATA/ATAPI/MFM/RLL support (IDE) [Y/n/m/?] y
Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support (BLK_DEV_IDE) [Y/n/m/?] y
Intel PIIXn chipsets support (BLK_DEV_PIIX) [Y/n/m/?] y
Include IDE/ATA-2 DISK support (BLK_DEV_IDEDISK) [Y/n/m/?] y
...
Include IDE/ATAPI CDROM support (BLK_DEV_IDECD) [M/n/y/?] m

SCSI device support (SCSI) [Y/m/?] y
...
SCSI disk support (BLK_DEV_SD) [Y/n/m/?] y
...
SCSI CDROM support (BLK_DEV_SR) [M/n/y/?] m
...
* SCSI low-level drivers
Serial ATA (SATA) support (SCSI_SATA) [Y/n/?] y
...
Intel PIIX/ICH SATA support (SCSI_ATA_PIIX) [Y/n/m/?] y

However I'm still not able to get DMA working..
Any suggestions would be really appreciated.. thanks a lot!!

I add ioports usage:

libata driver isn't working, because the counter is 0
may be the issue is in irq routing?

Again an excerpt from dmesg:

.. I'll try to use libata driver only because it looks like ata_piix driver cannot allocate IO resources.. do you agree?

Hello, I got exactly the same problem with an ACER TravelMate 4150LMi.

Outputs from hdparm/lscpi/dmesg can be found at http://tfc.duke.free.fr/acer.html

I tried to rebuild kernel too, but still no DMA... ;-(

I don't know why I have the message :

ide0: I/O resource 0x1F0-0x1F7 not free.
ide0: ports already in use, skipping probe

and then hard disk is on hdc instead of hda...

If you find something new, please post-it !

EDIT: found on LKML: http://www.ussg.iu.edu/hypermail/lin...05.2/1619.html
Perhaps it'll be fixed in the future... (I hope :-))

Look at http://marc.theaimsgroup.com/?l=linu...piix+ICH6M&q=b, there are some interesting notes.

These threads are very interesting. There is a patch (not clean) that I have applied on the PIIXn module and I could enable DMA !!! I got 28 MB/s on /dev/hdc (hard disk) instead of 2 MB/s and could play a DVD movie !
-> http://marc.theaimsgroup.com/?l=linu...2992832526&w=2 but THIS IS NOT THE FINAL PROPER SOLUTION, it's a hack, it works in my case (and probably your) because I have only PATA disks, no SATA...

Moreover, it seems that it is going (or already?) to be fixed in ata_piix soon, according to http://www.forbiddenweb.org/viewtopic.php?id=39027 the fix must be enabled manually because “SATA ATAPI support is disabled by default because the code is not yet complete.”, Jeff Garzik said.

Hello !

I also have an acer travelmate 4150lmi, and I have, of course, the same problem... Could you post or send me your .config file ?

Thanks a lot !

Ok here is what I did :
* I downloaded the 2.6.10 kernel from ubuntu packages (because I'm running Ubuntu on this machine).
* I ran menuconfig (make menuconfig) and leaved it with default config. Here is it : http://tfc.duke.free.fr/old/tmp/.config (note that you can change the default arch to Pentium-M instead of i386).
* I applied this patch^Wwork-around manually : http://marc.theaimsgroup.com/?l=linu...2992832526&w=2 ; but I could'nt add the line DECLARE_PIIX_DEV("ICH6M") (kernel too old for that I suppose).
* I rebuild it (make, make modules_install, cp arch/i386/boot/bzImage /boot/vmLinuz-2.6.10, cp System.map /boot/System.map-2.6.10, mkinitrd -o /boot/initrd-2.6.10 2.6.10, edited /boot/grub/menu.lst to add my new kernel).

I rebooted and the DMA was working :-)

hdparm test with 2.6.10 :

/dev/hdc:
 Timing cached reads:   2568 MB in  2.00 seconds = 1282.91 MB/sec
 Timing buffered disk reads:    8 MB in  3.41 seconds =   2.34 MB/sec

/dev/hdd:
 Timing cached reads:   3064 MB in  2.00 seconds = 1531.47 MB/sec
 Timing buffered disk reads:    2 MB in  3.37 seconds = 607.81 kB/sec

hdparm test with 2.6.10 + PATCH :

/dev/hdc:
 Timing cached reads:   2144 MB in  2.00 seconds = 1072.16 MB/sec
 Timing buffered disk reads:   86 MB in  3.02 seconds =  28.49 MB/sec

/dev/hdd:
 Timing cached reads:   3156 MB in  2.00 seconds = 1576.66 MB/sec
 Timing buffered disk reads:    8 MB in  3.59 seconds =   2.23 MB/sec

I could play a DVD movie fine :-)

[/dev/hdc is hard disk, /dev/hdd is DVD drive, both PATA]

Now I will try to build a 2.6.12 kernel, using ata_piix where it should be properly fixed : according to http://www.forbiddenweb.org/viewtopic.php?id=39027, there is just this little change to do :

You'll need to enable ATAPI support for ata_piix in include/linux/libata.h Change: #undef ATA_ENABLE_ATAPI into #define ATA_ENABLE_ATAPI

I will repost here latter for conclusions.

[edit: je me suis fait chier à écrire tout ça en anglais alors que tu parles français ! ;o)]

[Petite remarque: moi aussi je n'avais pas vu que tu parlais français... Mais si cela ne t'ennuie pas, on peut continuer en anglais vu que c'est un forum anglophone, comme cela ca pourra surement servir à d'autres...]

OK thank you for your reply !

But how did you manage to boot or install ubuntu (5.04 ?) ? On my laptop, it doesn't detect the cdrom drive during the boot instance...

I will try to compile a 2.6.12 kernel, and if it fails, I will try a 2.6.10...

I installed Warty 4.10 and then upgraded to Hoary 5.04 (no problem has been encountered). I have also tried a daily CD image of breezy (july 16th 2005) and the IDE drives were still not detected... I bypassed this problem unloading ata_piix and ide-generic modules and reloading them : ide-generic first, and then ata_piix. But ata_piix caused a segfault and then hardware detection failed in the install process... I think we should open a bug. It has been corrected with latest CD images of Mandriva (10.1 and 10.2 failed too), probably because it uses a 2.6.12 kernel for the installer.

Hello David !

I was about to let you a message on linuxfr to advice you to have a look here.
I'm currently compiling a 2.6.12 modified with the hack and crossing the fingers !

Do you think that it is still necessary to add

ide-generic
ata_piix
sd_mod

in the initrd module list in order the DVD to be seen ?

I have'nt tried it yet (I'll do this afternoon), so I don't know. Try it with and without. Don't forget the #define ATA_ENABLE_ATAPI.

The soft trick described in

http://www.forbiddenweb.org/viewtopic.php?id=39027

also works on a standard debian 2.6.11 kernel, as described by

http://irbs.sourceforge.net/toshiba-...-howto-en.html

I didn't put anything in /etc/mkinitrd/modules

The DVD becomes sr0 with DMA 33 enabled.

Strangely, my former eth1 becomes eth2 !

I did not switch to 2.6.12 due to a current problem with ipw2200
(fix exists, see http://www.bughost.org/bugzilla/show_bug.cgi?id=702 but
I did'nt succed at once, and I'm a bit fed up with linux tricks.

Thanks for your help.

I haven't been able to get it working with the 2.6.12 kernel, and I'm quite bored so I will stay with the 2.6.10 from my Hory with the 4 lines patch for the 82801FBM.

gromf88 has found me on IRC, I give him my kernel and it worked. You can download it at : http://tfc.duke.free.fr/old/tmp/acer...l-acer.tar.bz2

This is a 2.6.10 kernel from Ubuntu hoary. You will need to copy the iwp2200 firmware files in order to get the WIFI working with this kernel.

You can try my 2.6.12 kernel at

http://www.univ-orleans.fr/mapmo/mem.../medion/noyau/

Got support for ipw2200 by compilling manually
ipw2200-1.0.6.tgz
