[Xen-ia64-devel] [PATCH] [RFC] paravirt_alt

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Hi all.

This patch introduce binary patching functionality of xenLinux/IA64.
The goal is to reduce paravirtualization overhead and make
it more generic rather than xen specific.


I tested kernel compile on bare metal. The result doesn't show
any noticiable time difference.
I tried virtbench local. It showed binary patched kernel seems to be
slightly faster. But the difference is very small so that I'm not sure
the difference is meaningfull.

thanks,
