 Posted: Tue Mar 13, 2007 6:19 pm Post subject: cant enable DMA on dvd/cdrom drive |
 |
|
I've noticed that DVD burning is painfully slow with k3b. (Estimated throughput during write of 0.50x according to k3b).
K3b tells me that DMA mode is off and it will impact performance, but I cannot get it to turn on:
~ $ hdparm /dev/hdc
/dev/hdc:
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Inappropriate ioctl for device
I get the usual error:
~ $ sudo hdparm -d1 /dev/hdc
Password:
/dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

I've been through the forums and tried the various suggestions for issues that appear similar, no luck. My kernel (to my knowledge) is correct. Below is what I believe would be the applicable .config entries:
/usr/src/linux $ egrep -i "pci|sata" .config

| um... I dont know actually. The "n00b" under my name should probably say "clueless n00b". If you can tell me what to type or where to look, I'll get that info for ya. I'm currently not listing any extra kernel parameters at boot time if that's where I would do it. |

As root:
a) go to /usr/src/linux.
b) make menuconfig
1. Chipset support and IDE support: device drivers, ATA/ATAPI/MFM/RLL support-> select the matching chipset of your mainbaord. Also activate DMA by default.
2. If you don´t know, which chipset is used on your mainboard, consult the mainboard manual or use lspci -v. |

| Already done. (I grepped ide and sata out of my .config for my current settings. That should include the section(s) you're refferring to and the appropriate flags are set to yes. The laptop has an intel ICH6M chipset. |

Could you post the output of "lspci" so we can see the IDE/SATA controllers you have?
Could you also say which port (if you have two IDE ports) it is plugged in to?

Thanks. It looks as though it must be a combined SATA/IDE and the information on your Matshita DVD-RAM drive seems to show that it's IDE.
The driver that a search turns up for the Intel 82801FBM SATA controller is ahci, which you have. However, you also have ata_piix which, from dmesg, appears to have taken over one of the ide ports.
Would you like to try removing all SATA other than ahci and Intel Combined (which may be automatic), that is | Code: | <*> ATA device support
<*> AHCI SATA support
< > Intel PIIX/ICH SATA support
< > Intel PATA MPIIX support
< > Intel PATA old PIIX support (Experimental) |
under "Serial ATA (prod) and Parallel ATA (experimental) drivers" and | Code: | | < > Intel PIIXn chipsets support |
under "ATA/ATAPI/MFM/RLL support".
I don't think that | Code: | <*> Include IDE/ATA-2 DISK support
<*> Include IDE/ATAPI CDROM support
[*] Generic PCI bus-master DMA support
[*] Use PCI DMA by default when available |
under "ATA/ATAPI/MFM/RLL support" is going to hurt. I don't think it applies to SATA but I'm not entirely sure that it has no influence at all.
Note that you must have SCSI disk and CD-ROM support | Code: | Device Drivers --->
SCSI device support --->
<*> SCSI disk support
<*> SCSI CDROM support |
but it wouldn't work at all if you hadn't

It looks like my driver is the Intel PIIX/ICH SATA support one, not the ACHI SATA support. I tried it just with the ACHI and couldnt boot up. I then removed ACHI and added back in Intel PIIX/ICH as the only item chosen in that section of the config and the system came up. Still no luck with the DMA issue though.
I think I'm going to try pulling the IDE stuff you referenced next to see what it does.
Edit: yanking the IDE stuff wasnt good. the DVD/CD drive disappeared. I added IDE/ATAPI back in and recompiled. |

Sorry, my mistake.
I missed the entry in ata_piix under SATA, so, revising my post | Code: | <*> ATA device support
< > AHCI SATA support
<*> Intel PIIX/ICH SATA support
< > Intel PATA MPIIX support
< > Intel PATA old PIIX support (Experimental) |
When you have got ata_piix as the only driver, could you post that part of /var/log/messages between the line | Code: | | Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 |
and the start of the USB discovery, something like | Code: | | ehci_hcd 0000:00:1d.7: EHCI Host Controller |

No problem. One of the few things I did learn in kernel 101 was to always save your last good kernel as an entry in your grub.conf in case the new one you're trying doesnt like your machine.

Hmm, I can't see anything wrong.
The bit | Code: | ide0: I/O resource 0x1F0-0x1F7 not free.
ide0: ports already in use, skipping probe |
which was in your first post of dmesg doesn't appear to have had any bad effect | Code: | | Probing IDE interface ide1... |
then finds the MATSHITADVD-RAM and finds ports 0x170-0x177,0x376 for it.
When ata_piix starts, it finds 0x170 in use but, undisturbed, goes on to find the Toshiba SATA disk.
The apparent conflicts may be due to the same controller handling both IDE and SATA devices and, therefore, to be expected.
So, unfortunately, after all your posting and delving ... nothing. 
It could be a bug in the Intel combined code and a later kernel may solve your problem. Perhaps you might like to try gentoo-sources-2.6.20-r2 or mm-sources-2.6.21_rc3-r2 or even the latest prepatch, 2.6.21-rc3.

If you feel adventurous then apply the libata PATA patch from my web page and compile a kernel with CONFIG_IDE=n and most stuff should work. Folks are still reporting some problems with libata and CD burning however. |
but see the following message where, after applying the patch | Quote: | | Funny situation - I cannot figure what my root device is. Earlier without the patch it was /dev/sda3 and now I try everything (hda3, hdb3, hdc3, hdd3, sda3, sdb3...) but it panics - not able to mount rootfs. |
So good news: it is being worked on â bad news: it's not there yet.

I added "combined_mode=libata libata.atapi_enabled=1" to my kernel.
It took me a few minutes to find them after I rebooted, but I now have a /dev/cdrom2 and a /dev/dvd2 symlinked to the /dev/sr0 device - so the CDROM drive now appears to be in the correct mode. Of course, hdparm wont work anymore, so I cant tell if it has DMA enabled or not.
cv4621@newtardis ~ $ sudo hdparm -d1 /dev/sr0
/dev/sr0:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Function not implemented
I'll have to throw a disk in and burn it to see if there was any performance improvement or not to tell if DMA is actually enabled or not. Here's the latest messages output:

Seems to be making progress.

> is hdparm useful with sata drives, does it work with sata drives?
SATA drives in the 2.6 kernel are handled by the new "libata" SCSI driver. If you add the "ATA passthru" patch (from Jeff Garzik) to your kernel, then hdparm can work with those drives.
Some flags, like "-d", are not supported by libata. Currently, ALL SATA hard drives use DMA, so there is no need for -d. But eventually libata will have to implement ATA PIO (for CF cards..), and at that time it may (or not) begin to support the "-d" flag. |
smartmontools also uses the "ATA passthru" and has worked now for a kernel release or two.

DMA definitely appears to be working now. MUCH better speeds.
I really do appreciate the help |
