 Posted: Tue Sep 07, 2004 8:24 pm Post subject: Can/How do I get my DMA working? |
 |
|
OK; I've got really far with getting Gentoo just how I like it (it's taken a while) but one of the things bothering me is: DMA.
My hard drive is, at the moment, just plain slow. I have to forget about even a half-decent level of responsiveness while i'm emerge syncing or unzipping, or while slocate updates.
I know that DMA will improve this, and I know how to turn it on, but it won't go:
| Code: |
# hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
|
I'm guessing it's because I don't have support for my IDE controller (?). /proc/pci gets me:
| Code: |
Bus 0, device 17, function 1:
IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 6).
Master Capable. Latency=64.
I/O at 0x1100 [0x110f].
|
So, my question is, how do I get it working? Or do I have to languish in the world of sloooow disks forever? |

Since you have a relatively bog-standard VIA VT686 southbridge, this should not pose any great problems.
What does you kernel .config have in the IDE subsection ?

I think adaptr's along the right lines; you need to enable vt82cxxxx support: CONFIG_BLK_DEV_VIA82CXXX=y.
Googling for 'HDIO_SET_DMA failed: Operation not permitted VT82C586A' finds a few people who've had the same problem. |

Ok, I'll try enabling it, and see what happens...
And I tried googling, but not for that... whoops. |

Erm... lspci ?
or cat /proc/pci, or possibly dmesg | less.
All of these should yield an IDE controller with make and model attached.

lspci and cat /proc/pci don't work. "command not found" + "no file or dir"
I don't see a make/model for an ide controller using dmesg

Excusing your piggy-backing on another thread with nary a "hello, I'm curious" - I'm feeling magnanimous today:
To get lspci do an
