In the process of solving this one, I've got to (another) of the
blocking points...

If Xen is going to need an x86 emulator, there is also need of a small x86 emulator based on klibc as part of the general Linux kernel. People often put video cards with x86 ROMs into PPC/Itanium machines since the x86 versions are half the price. The general idea is that during the boot process the emulator would run the x86 ROM and initialize these cards. The same code would be used to initialize secondary cards on all architectures. After klibc gets added to the kernel tree I'd also like to see the emulator and video reset program added. -- Jon Smirl jonsmirl@xxxxxxxxx _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
