Xenoprof for xen-unstable (was Re: [Xen-devel] [PATCH] Xenoprof: Enabling performance profiling in Xen)



This is my feeble attempt to port xenoprof to xen-unstable.  I really 
did not make a lot of changes, but(!) the one big caveat is that it 
does not work :)

The 2 patches attached are for ./xen and for ./linux-2.6.11-xen-sparse.  
Both should patch cleanly against bk (2005-04-15) and should compile 
fine.  It does boot, but starting profiling causes xen to stop (output 
below).

I'm not sure if this is of any use to anyone (being that it does not 
work yet), but I'd thought "why not" and maybe someone with more 
knowledge would point out some obvious errors I made.
