[Xen-devel] What's the function of evtchn

[ææå <Chunqi Li> <yzt356@xxxxxxxxx>]

Hi all,

I'm reading some code of Xen-4.0-unstable and I occurred some obstacle when reading xen-unstable\unmodified_drivers\linux-2.6\platform-pci\evtchn.c. I don't exactly know what evtchn is, so I can't understand some of the code. I search evtchn in google but get few information.

Can anyone help? Thanks.
