Subject: [Qemu-devel] DMA with Knoppix and qemu (cvs-version)

Hi,

i just booted a recent knoppix-cd (4.0.2) and i'm trying to enable DMA,
but it won't work!

I started qemu with that command:

qemu -m 256 -cdrom knoppix.iso -boot d

But inside knoppix, a "hdparm -d1 /dev/hdc" won't work:
  HDIO_SET_DMA failed: Operation not permitted


Are there some issues with qemu's DMA support and Linux?
(qemu does have DMA support, doesn't it?)


Greetings
  Sven
