[gentoo-user] unable to activate dma mode

[Stefán István]

Hello!
I'm not able to activate dma mode for cdrom drive in my laptop.
# hdparm -d1 /dev/hdd

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

I have the following hardvers:

I think the problem is that there is no driver for this chipset compiled into 
the kernel. But I don't know which driver should be compiled into. I tried 
Intel PIIXn but it didn't help.

Thanks for the help in advance,
István

You will need to set CONFIG_IDE=n, enable SCSI cdrom support 
(CONFIG_BLK_DEV_SR) and enable the Intel PIIX sata driver 
(CONFIG_SCSI_ATA_PIIX).

DMA should then work perfectly fine. However one side effect is that your 
cdrom drive will become /dev/sr0, although I guess this can be fixed with a 
udev rule.

Yeah, but you'll still get the /dev/cdrom, /dev/dvd, /dev/cdrw, etc
links, so I _really_wouldn't bother.  I've always found it confusing
for a cdrom device to show up as hdX anyway.

Isn't this deprecated?  Wouldn't a better choice be to install the
SATA driver ebuild?  (Mainly trying to eliminate my own confusion here.)

Not according to the kernel configuration help.

What sata driver ebuild?

carcharias linux # eix sata

No, libata is most certainly not deprecated and what ebuild are you talking 
about?
