 Posted: Tue Mar 28, 2006 12:08 am Post subject: Very poor cdrom performance |
 |
|
When I copy files from my cd drive (TSSTcorp DVD+/-RW TS-L532B, ATAPI CD/DVD-ROM drive), my system slows down like hell.
The CPU is barely loaded, but when I move my mouse pointer around, it 'jumps'.
I have tried using ide-scsi, ide-cd, and both 2.6.15 and 2.6.16, but nothing helped.
My drive is set to udma2, and no special settings.
Any suggestions? |

Try booting the live cd and find out if it happens there. Could be kernel issue.

grades,
Boot normally and run Put in your CDROM device.
What does it say about Using DMA ?
If its off, (0) read to learn how to turn it on.
If hdparm cannot turn on DMA, you have a bit missing from your kernel.

I know how to use hdparm, and I tried every possible setting, but nothing helped. My drive worked fine three days ago when I still ran FreeBSD though, so this isn't a hardware problem.
edit: Sorry, I misread (udma instead of dma  ). DMA is indeed off, and enabling it fails with the following message: HDIO_SET_DMA failed: Operation not permitted. I was logged in as root, so I am indeed missing a kernel part, but which one? |

grades,
Please post the IDE line from lspci, then I can tell you how to set up your kernel.

I moved to ide-scsi again, and patched some kernel files. I can now transfer files at 3,6 Mb/sec, which should be normal for a 24x drive, right? 
I found the solution here: https://forums.gentoo.org/viewtopic-p-2870691.html#2870691
Thanks for helping me |

/dev/hdd:
ATAPI CD-ROM, with removable media
Model Number: _NEC DVD_RW ND-3500AG

Firmware Revision: 2.1A
Standards:
Likely used CD-ROM ATAPI-1
Configuration:

step,
I need the output of | Code: | | /sbin/hdparm /dev/hdd |
whun you use -I or -i It provides information about various capabilitys that may or may not be in use.

no problem, here it is:
| Code: | /sbin/hdparm /dev/hdd
/dev/hdd:
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: Invalid argument |
and i use 2.6.15-gentoo-r1 kernel |

step,
There you are | Code: | | using_dma = 0 (off) |
You also posted | Code: | | Intel Corporation 82801EB (ICH5) SATA Controller |
but thats not where your CD-ROM is connected, unless you have a rare SATA CDROM.
I'm guesing you have a an Intet ICH5 Parallel IDE controller too.
You need the following kernel options, all built in ...
| Code: | Device Drivers
ATA/ATAPI/MFM/RLL support
ATA/ATAPI/MFM/RLL support
Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support
Include IDE/ATA-2 DISK support (Only if you have a PATA hard drive)
Use multi-mode by default
Include IDE/ATAPI CDROM support
generic/default IDE chipset support
PCI IDE chipset support
Sharing PCI IDE interrupts support
Generic PCI IDE Chipset Support
Generic PCI bus-master DMA support
Use PCI DMA by default when available
Intel PIIXn chipsets support |
Its the last item that provides the chip set specific code to enable DMA in your Intel ICH5 chip set.

You are correct. I do not have a rare SATA CDROM.
All those settings, you mentioned, are OK. |

step,
I have a feeling that the solution to your problem was posted about 9 months ago in relation to the ICH6 chipset. It involved enabling SATA wether it was needed or not and turning off autodetection of the IDE.
Unfortunately, I cant find the thread now.

I also did try Grades link https://forums.gentoo.org/viewtopic-p-2870691.html#2870691 but then I have no DVD at all.
I also enabled and disabled the "SCSI emulation support" in ATA/ATAPI/MFM/RLL support.
Nothing!
02.04.2006 - So I have searched the net and forums but nothing.
I still get poor performance and:
| Code: | /sbin/hdparm -d1 /dev/hdd
/dev/hdd:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
|
Anyone? |
