 Posted: Wed May 25, 2005 5:45 am Post subject: Jerky DVD playback |
 |
|
I am one of those chumps who can't get DMA enabled for his DVD drive, causing jerky playback.
Here's my DVD drive (which, incidentally, works fine in my other Gentoo PC):
| Code: | # hdparm -i /dev/hda
/dev/hda:
Model=LITE-ON DVDRW SOHW-1653S, FwRev=CS02, SerialNo=
Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=0kB, MaxMultSect=0
(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
IORDY=yes, tPIO={min:227,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2
AdvancedPM=no
Drive conforms to: device does not report version:
* signifies the current active mode |
Here's me trying to turn on DMA:
| Code: | # hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off) |
From what I've read, the solution to this is to compile proper support for my chipset into the kernel. However, I've done that and gotten nowhere. Here's my .config:
| Code: | #
# ATA/ATAPI/MFM/RLL support
#
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
#

The specific support is CONFIG_BLK_DEV_PIIX, which is for ICH chipsets. And that's what I have. [url=http://www.msicomputer.com/product/p_spec.asp?model=865PE_Neo2-PFS_(Platinum_Edition)&class=mb]This[/url] is my motherboard, which is based on the Intel 865PE.

What can I do? This is a home theater PC, so DVD playback is important. |

take the generic out and recompile the kernel and that should take care of it.
Since
CONFIG_BLK_DEV_PIIX=y
CONFIG_BLK_DEV_IDEDMA=y
are included with
CONFIG_IDE_GENERIC=y
CONFIG_BLK_DEV_GENERIC=y
it may not work. I had the same problem and once I took out generic and only had my chip set support it worked.

Thanks, but unfortunately this didn't help.
When I rebuilt the kernel without those two "generic" options and rebooted, the PC could no longer see the DVD drive. When I put back CONFIG_IDE_GENERIC (leaving CONFIG_BLK_DEV_GENERIC unset), it returned to the old state: I can see the DVD drive but setting DMA is "not permitted." |

| Generic IDE support can slow your hard drive down as it may kick in before your chipset driver does so disable it if you have a driver for your chipset. |

But if I disable generic IDE support, my PC can't even see my DVD player! That's what I said in my last message. Also, I don't have an IDE hard disk.
This may not be relevent, but I have discovered that if I turn on my PC with a DVD in the drive (this is with generic + PIIX support compiled in), kernel bootup gets to "hda: <CD/DVD drive description>", then pauses while the drive begins making all kinds of awful grating noises. It sounds like it's dying. I need to pop open the tray and extract the disk, and then the boot process continues. |

I've tried rebuilding my kernel in five different combinations. Nothing allows me to turn on DMA.
What can I do? |

| Check the BIOS. Sometimes enabling both PATA and SATA when you build support for one, the other or both causes problems. Try disabling PATA in the BIOS and only SATA... or vice versa. |

Ahhh! Your name is bollucks, yet you speak anything but. 
It took some experimentation, but I finally got it. In case this is helpful to anyone else, here's what I did.
First, my system has 1 x IDE DVD-RW drive and 1 x SATA hard drive. This was the page in my AMIBIOS v3.31a that I messed around with:
| Code: | Integrated Peripherals
--> On-Chip IDE Configuration
--> On-Chip ATA(s) Operate Mode [Legacy / Native]
ATA Configuration [Disabled / P-ATA Only / S-ATA Only / P-ATA + S-ATA]
S-ATA Keep Enabled [Yes / No]
P-ATA Keep Enabled [Yes / No]
P-ATA Channel Selection [Primary / Secondary / Both] |
My starting configuration was Legacy / P-ATA + S-ATA / Keep P-ATA Enabled / Both. With this, I could see the DVD drive, but not enable DMA, which caused jerky playback.
This configuration left me unable to see the DVD drive at all: Native / P-ATA + S-ATA / No to Keep P-ATA Enabled. So did Legacy / P-ATA Only / Keep S-ATA Enabled / Secondary Channel (although I found out later the only thing wrong here was that last option: Secondary Channel selection).
This configuration gave me a kernel panic, with the PC unable to see the hard drive! Legacy / S-ATA Only / No to keep P-ATA Enabled.
This one worked, allowing DMA, except every time the DVD drive was accessed, the PC spat out a bunch of "Disabling IRQ #10" messages and thought about life for a while before responding: Legacy / S-ATA Only / Keep P-ATA Enabled / Both Channels.
This one just worked! The PC can see both the DVD drive and the hard drive, and DMA works for both: Legacy / P-ATA Only / Keep S-ATA Enabled / Both Channels. It also worked if the last option (Channel Selection) was "Primary".
Now, I have no idea what all this means, and if anyone wants to enlighten me, that would be very interesting. But I'm just grateful to have the thing working. Thank you! |

A handle says nothing of who someone is or actually might be.
You're welcome. |
