This version supports: IO instructions DMA Interrupts PCI Bus scan IOremap The patch is against: bk://namesys.com/bk/linux-2.5-uml Config your kernel to turn on VPCI and whatever drivers you are interested in. You may need to include Kconfig for other drivers from arch/um/Kconfig. arch/um/umlh is a small module that needs to be built and run in the host. It provides DMA and interrupt forwarding. You need to run UML as root. I use sudo to do this. Make sure you don't have any drivers loaded in the host for the hardware you want to use in UML. I can run framebuffer drivers with this patch (not framebuffer console). I have also had some success with run USB devices but their are still some issues with USB. This patch will probably work for audio cards too but I don't have any handy to check. Please give it a try and give me some feedback. ===== Jon Smirl jon...@ya... __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

The is a snapshot of my VPCI work. It is still losing interrupts (which hangs UML) so it is not useful yet. It does illustrate how I am using get_vm(), max vm range and the fault handlers to dynamically map things into the kernel address space. It also provide an example of how to write a host device driver which can communicate asynchronously with UML. patch is bz2 since it is getting too big for the mailer. ===== Jon Smirl jon...@ya... __________________________________________________ Do you Yahoo!?
