Netback and netfront only use one event channel to do tx / rx notification. This may cause unnecessary wake-up of process routines. This patch adds a new feature called feautre-split-event-channel to netback, enabling it to handle Tx and Rx event separately. Netback will use tx_irq to notify guest for tx...

This series implements NAPI + kthread 1:1 model for Xen netback. This model - provides better scheduling fairness among vifs - is prerequisite for implementing multiqueue for Xen network driver The first two patches are ground work for the third patch. They aim to reduce memory footprint of netback. The third patch has the real meat: - make use of NAPI to...

hi I've some problems with netback 1.what's mmap_pages for, which come from balloon operation ？ mmap_pages = alloc_empty_pages_and_pagevec(MAX_PENDING_REQS) 2.what's the meaning of "refcnt" defined in netif_t (netif->refcnt) 3.irq enable and disable such as disable_irq(netif->irq); why netback use such enab...

A buggy or malicious frontend should not be able to confuse netback. If we spot anything which is not as it should be then shutdown the device and don''t try to continue with the ring in a potentially hostile state. Well behaved and non-hostile frontends will not be penalised. As well as making the existing checks for such errors fatal also add a new check...

When counting required slots for skb, netback directly uses DIV_ROUND_UP to get slots required by header data. This is wrong when offset in the page of header data is not zero, and is also inconsistent with following calculation for required slot in netbk_gop_skb. In netbk_gop_skb, required slots are calculated based on offset and len in page...
