 |
|
Hi when I boot up with the live CD, dma is activated, but when I boot up normally I get a message that dma is not on...If I try to activate it with hdparm, it is not possiblem...I have installed 2.6.4 kernel and my chipset is VIA KT333...I cant find this in the kernel...Where can I find settings for this in the kernel!!!
Bye |

In the IDE/ATA section the last options are for chipsets, pick yours, recompile and reboot. 
edit: I checked it quick, it can be found here: Device Drivers --> ATA/ATAPI/MFM/RLL support |

I have the same problem. Things like fsck.reiserfs give warnings about dma not being enabled. # hdparm -i /dev/hda gives:
| Code: | root@zidane:~# hdparm -i /dev/hda
/dev/hda:
Model=Maxtor 4D040H2, FwRev=DAH017K0, SerialNo=D27YDXNE
Config={ Fixed }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57

CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=80043264
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}

AdvancedPM=yes: disabled (255) WriteCache=enabled
Drive conforms to: ATA/ATAPI-6 T13 1410D revision 0:
* signifies the current active mode
|
and yet # hdparm -d1 /dev/hda gives:
| Code: | root@zidane:~# hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

Are you sure you already enabled the correct IDE chipset support inside the kernel?

AFAIK, it's been enabled. I'll double-check though. |

Exactly the same problem here... Now compiling kernel with ALL chipsets support  (hope to get different results...)
However, other things do not work.... I enabled 32-bit support, and the "Keep settings" option... But only BEFORE REBOOT i get:
| Code: | Darkness root # hdparm -c /dev/hda
/dev/hda:
IO_support = 1 (32-bit) |
... After reboot it turns back to 16-bit.... Damn... 
Can anyone please release the secret of IDE drives and HDPARM?!

The secret is :
Hdparm is not needed if you configure your kernel correctly.
Here is an example :
The computer I am using right now has an SiS chipset (according to lspci)
| Code: | # lspci
...
0000:00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] (rev d0)
... |
So I want to include this driver in my kernel.
| Code: | Device Drivers --->
ATA/ATAPI/MFM/RLL support --->
<*> SiS5513 chipset support |
See, it works.
| Code: | # hdparm /dev/hda /dev/hdc
/dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 120103200, start = 0
/dev/hdc:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 120103200, start = 0 |
| Code: | # hdparm -tT /dev/hda /dev/hdc /dev/md0
/dev/hda:
Timing buffer-cache reads: 1060 MB in 2.00 seconds = 529.29 MB/sec
Timing buffered disk reads: 134 MB in 3.01 seconds = 44.55 MB/sec
/dev/hdc:
Timing buffer-cache reads: 1056 MB in 2.00 seconds = 527.29 MB/sec
Timing buffered disk reads: 134 MB in 3.04 seconds = 44.13 MB/sec
/dev/md0:
Timing buffer-cache reads: 1044 MB in 2.00 seconds = 521.30 MB/sec
Timing buffered disk reads: 260 MB in 3.02 seconds = 86.13 MB/sec |

Hey,
I had this problem a while ago, if you search, you will find.
However, to put things briefly, you need to make sure you enable:
Device Drivers --> ATA/ATAPI.... --> Generic PCI bus-master --> VIA82cxxx chipset
Because it works on live CD and not on your computer, this means you have a kernel problem.
Also make sure when you build your kernel you:
-mount /boot
-modify grub configuration file if you decided to switch between old and new kernel (I made this mistake and realized the two options pointed to the same old kernel instead of the new one)
This SHOULD solve your problem.
Good Luck

Well, isn't my kernel correctly configured? I've selected the SiS with a |*|...
No it doesn't I think you didn't fully read my first post! Notice i've done everything (and i've posted it step by step!)

Phk, I am glad to hear you got it working.
I never realized that Generic IDE support would make the drive run slowly like that. |
