I'm still working on DMA and IRQ support. UML - user mode linux. UML runs the Linux kernel as a process. For example my PC is booted on 2.4 and the UML runs 2.5. The advantage to this is that you can use gdb/ddd to debug the fb driver code. It's actually kind of neat. I use one gdb inside of UML to control the fbtest app and another gdb to step the code inside of the fb driver. Is anyone interested in trying this out? You need two video cards in your machine one for X and one for the target framebuffer. I am using AGP for X and targeting a PCI Rage128. ===== Jon Smirl jonsmirl@yahoo.com __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
