[gentoo-user] DMA for /dev/cdrom ?

[gentoo-user] DMA for /dev/cdrom ?

[Andreas Burghardt]

Hello everyone,

I really like to use DMA for my cdrom/burner but I cant figure out how to make
it working!
I have a

hdc: HL-DT-ST DVD-RW GWA-4082N, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15
hdc: ATAPI 24X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache

DMA is working fine for my disk but for cdrom I only get:

tapa ~ # hdparm -d1 /dev/cdrom 
/dev/cdrom:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma    =  0 (off)

Does anyone of you know if there is DMA support for this cdrom-drive and if
there is what to compile in the kernel? I already gave up to search ... because
nothing wanted to work!

Regards,

   Andreas Burghardt

Two hints, perhaps they help
- "hdparm -i $DEVICE" will display what the device can support
- I would run hdparm on the physical device file, that is /dev/hdc, not on
the cdrom-link.

It sounds like a plain old ATAPI drive, so should work with the generic
stuff. No specific knowledge about your drive, though.

tapa ~ # hdparm -i /dev/hdc   

/dev/hdc:

 Model=HL-DT-ST DVD-RW GWA-4082N, FwRev=CB03, SerialNo=4CA07617AFA8

  Drive conforms to: ATA/ATAPI-5 T13 1321D revision 3:  ATA/ATAPI-2
  ATA/ATAPI-3 ATA/ATAPI-4 ATA/ATAPI-5

 * signifies the current active mode

Hmm, I see AdvancedPM=no ...? Before I changed to Gentoo-Linux I was using
Ubuntu. If I copied files from the cdrom it was _very_ FAASST ... but now ... 

Thx for your help!

Well, the above shows that you have udma2 activated on your device.

I'm very sorry, but you all see that I'm quite new to Linux ...
If UDMA2 is activated for the drive why is the data trasfer slow and

tapa ~ # hdparm -d1 /dev/hdc

/dev/hdc:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma    =  0 (off)
   
Why cant I activate DMA?

What kind of chipset does your motherboard use?
You can check it with the lspci command. Maybe you have to load a kernel 
module for that chipset...

Looks like the same chipset as my laptop. In order to get DMA working I had to 
set CONFIG_IDE=n and enable SCSI cdrom support and CONFIG_SCSI_ATA_PIIX.

Your cdrom device will become /dev/sr0 and you shouldn't have any issues with 
DMA.

I suggest that instead of compiling the chipset kernel driver as a module, you 
build it in the kernel.  This has worked for this problem that others had in 
the past and may hopefully fix yours.

HTH.
