about vmx_intercept.c

about vmx_intercept.c

[Miao Feng]

we found something interesting in vmx_intercept.c providing a technique

for high-performance io accessing.

then, what is the use of this technique? for xen-aware? what xen-aware
exactly is?
in terms of VT, we don't have to modify guest os to run on xen 3. if we
are expecting high-performance io, do we have to modify guest os, or
just install some kind of xen-aware (xen-something)?
and, where xen-aware lies? xen space? dom0 space? domU space?

thanx in advance.

anyone? any idea?

[Jiang, Yunhong]

The vmx_intercept.c is to intercept some mmio/IO instruction on HV side.

As to the high performance IO , the VBD/VNIF patch have been sent out by
Xiaofeng, Ling. But vmx_interecept.c is not for it.

Thanks
