Hi!
I'm running a debian 3.0 System using kernel 2.4.19 (also tried 2.4.20).
On this system it's not possible to enable dma on /dev/hda (HDD IDE)
The MoBo is a VIA Board called VIA-C3M266 (CLE266 chipset)
Northbridge: VT8623
Southbridge: VT8235
My kernel is compiled with this features:
ATAPI/IDE/MFM/RLL support --> IDE, ATA and ATAPI Block devices -->
[*] generic PCI bus-master DMA support
[*] Use PCI DMA by default when available
[*] VIA82CXXX chipset support
And this is what hdparm tels me:
hdparm -d 1 /dev/hda:
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
What can I do to force my system to run using dma on /dev/hda.
Or is my CLE266 chipset a bit too new for being supported by 2.4.19/20?
Hope somebody is able to help me
