Subject: [RFC PATCH] New Xen netback implementation
Date: Fri, 13 Jan 2012 16:59:03 +0000 [thread overview]
Message-ID: <1326473949-22389-1-git-send-email-wei.liu2@citrix.com> (raw)
A new netback implementation which includes three major features:
- Global page pool support
- NAPI + kthread 1:1 model
- Netback internal name changes
This patch series is the foundation of furture work. So it is better
to get it right first. Patch 1 and 3 have the real meat.
The first benifit of 1:1 model will be scheduling fairness.
The rational behind a global page pool is that we need to limit
overall RAM consumed by all vifs.
Utilization of NAPI enables the possibility to mitigate
interrupts/events, but this is not yet done.
Netback internal changes cleans up the code structure after switching
to 1:1 model. It also prepares netback for further code layout
changes.
