Isn't UML supposed to be incorporated into the 2.6 kernel? Will this have any effect in the world of Alpha?
Cheers, David Creed

I want to run some virtual machines on my alpha to play around with with different distributions, kernel and such stuff. But noone of the popular emulators does imho work on linux/alpha (no emulation of the i386 instruction set like booch does).
qemu mostly works, except it tends to crash on larger programs. Maybe it is easy to fix. Or maybe not; the pages being larger is a major obstacle. Adding Alpha emulation should be pretty straight-forward... at least for emulating userspace.
I want also run a kernel in userspace, as in uml (testing some more or less obscure kernel patches).
So I asked on the uml-devel-list (user mode linux) how hard it is to port the uml patch to other plattforms than i386, because this approach seems to me to be the fastest (in terms of execution speed) and most generic one. The answers were spare, and I've extracted from the answers, that the most problems are the plattform specific ones :-|
It should be easier than for other platforms, since all interaction
with the MMU and similar things (timers etc) is done via firmware
calls. So all you need to do is implement the firmware interface,
which is pretty high-level and well documented.
Hm, I will see what I can do next year. But I cannot do that all by myself, since I haven't a deeper knowledge of the linux kernel.
See ftp://ftp.compaq.com/pub/products/alphaCPUdocs/alpha_arch_ref.pdf.gz
Thanks, I'll take a look into them.
