 |
|
I have a problem with a laptop acer 5672wmli that have the hard-disk sata of 100gb and the dvd drive pata.
the problem are that I can't activate the DMA on the dvd drive with hdparm.
All work perfectly, but when I use the dvd-drive the pc go very slow and also amarok block when play music.
In internet I read that the solution is to configure the kernel for look the dvd-drive how a sata, for example sr0.
The output of hdparm is:
| Quote: |
# hdparm -d1 /dev/hdc
/dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
# hdparm -d1 /dev/sda
/dev/sda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Inappropriate ioctl for device

I have also problem with DMA on dvd-drive. Just updated to Gentoo-2.6.18 kernel and now dvd-drive doesn't work at all (there was some ICH7-M patches in 2.6.18 ).

I have tested three version of kernel, 2.6.15, 2.6.17, 2.6.18, but for the devices I have ever used the same system, sda and hdc.
I don't nterstand one think, if there are a hd sata and a dvd pata, there are two controllers, one for sata nad one for pata or there are only one that control all?
Consequently in the kernel we can built-in the chpset driver for sata and a pata or only one? |

| With SATA drives you can ignore hdparm - especially since it doesn't work on sata; if your driver is working on sata then you always have dma regardless. There is nothing stopping you from building as many drivers into your kernel as you like as well, and you have both a sata and pata setup so you need to build the PIIX drivers into your kernel to get dma for your dvd. hdparm does not fix dma problems, it only can diagnose them. |

-> Hard Disk and CD/DVD Writer
I did kernel config with those instructions and now dvd-drive is /dev/sr0 and is working much better, system is not freezing anymore when reading disc.
Edit:
There is two SATA ports and one PATA channel in this chipset. My Hd is SATA (/dev/sda) and dvd PATA. |
