Subject: Implement 3-level event channels in Xen.
Date: Mon, 31 Dec 2012 18:22:32 +0000 [thread overview]
Message-ID: <1356978155-18293-1-git-send-email-wei.liu2@citrix.com> (raw)
This patch series implements 3-level event channel routines in Xen.
The implementation is as followed:
* Add a field evtchn_level in struct domain.
* Add pointers in struct domain to point to 3-level shared array.
* Add 2nd level selector in struct vcpu.
* Add a new op in do_event_channel_op to register n-level evtchn.
The exposed interface for registering is extendable, however only 3-level is
supported at the moment.
The routines for 3-level evtchns are more or less the same as 2-level ones.
