Hi folks,

I'm reading here and there about IDE DMA support in Xen 2.0.x
because it did not work for me (2.6.10). What should I expect
on the stable tree? What about the comments at
http://www.suse.de/~garloff/linux/xen/ about IDE DMA ?
To the best of my knowledge most of the commonly used IDE chipsets are supported. I'm not aware of any that Linux supports that Xen doesn't support (although I could be wrong).

IDE DMA support is perhaps one of the most common user problems with Xen. The default Xen config does not compile support in for most of the IDE chipsets. You most likely have to recompile your kernel sources and add the appropriate support for your chipset.

I hope to get some first hand infos.
