 Posted: Mon Nov 07, 2005 3:16 am Post subject: Can't get DMA to work for my DVD drive [SOLVED] |
 |
|
UPDATE 11/26/05
For anyone else with similar issues, my solution was to change my bios settings from Combination/Pata mode to AHCI mode. I had set it to the combo mode a long time ago for some complex reasons and forgot to set it back. So if your kernel has support for your chipset compiled in, and DMA still doesn't work, go into your BIOS screen and play with the settings there!
END UPDATE
I can't seem to get DMA enabled on my DVD drive

Me trying to enable DMA:

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

Here's what (i think) are the relevent portions of my kernel config

Any ideas for getting this enabled? No movies on the computer for me until it does

too much info.
do this and post the results: | Code: | | cat /usr/src/linux/.config | grep DMA |

sorry, wasn't sure exactly what is/isn't relevant...if I did i guess I wouldn't have to ask this question 
btw. I'm running gentoo-sources-2.6.11-r6
| Code: | # cat /usr/src/linux/.config | grep DMA
CONFIG_GENERIC_ISA_DMA=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
# CONFIG_BLK_DEV_IDEDMA_FORCED is not set
CONFIG_IDEDMA_PCI_AUTO=y

that is all fine so it must be something to do with hdparm. | Code: | | HDIO_SET_DMA failed: Operation not permitted |
that seems like you are almost doing it as a user. Are you doing it as root?

yup, i'm su'ing up before i do anything with hdparm
I know it's not a hardware problem per-say because it works fine in Windows.
I saw elsewhere that setting -X66 sets udma2 (which according to the info, my drive supports)
it appears to have success:
| Code: | chris # hdparm -X66 /dev/hdd
/dev/hdd:
setting xfermode to 66 (UltraDMA mode2)
|
but DVD playback is still unacceptably jerky and crappy... and hdparm -d 1 fails like i listed before.
could this maybe be a conflict with hald or udev? i doubt it because you don't need to mount the drive in order to play DVDs, but just a thought |
