...ge is rather cheap. Flushing an address range on every processors is also cheap (no IPI). Unfortunatly Xen common code flushes the whole TLB after unmapping grant reference. Currently, this is not done on IA64 because domain_dirty_cpumask is never set (bug!). We can flush TLB by range within destroy_grant_host_mapping. But then we need to disable the flush_tlb_mask call. What is the best solution?

I''ve been working form the netfront.c in the testing tree and using SLES 10 RC1 for i386 on a SMP box. When I stress the network using iperf in a domU, domU acting as client on a gigabit network, I occasionally get a panic at the dev_kfree_skb_irq(skb); line. This is the same panic as reported in http://lists.xensource.com/archives/html/xen-devel/2006-05/msg00919.html The trace

Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it
