Hi All，
I try to test the performance of netfront netback
I use xen4.4 and kernel 3.17-4
When I test the UDP speed
I found that if send package is larger than the MTU, xen-back will only one
queue at work.
And the speed is slow
Is there any way to makes multi queue working with package larger

Hi,
I want to know what is the criteria followed in Xen for scheduling VCPUs.
Assume below scenario:
- Run 2 VPCUs on 1 Physical CPU
- VCPUs does not trap on WFE or WFE ( either by WFI/WFE trap is
disabled in HCR OR no WFE/WFI in EL1 is executed).
In such scenario, does Xen assumes that

OK, but could you :

2) split the too long line

Sure, I'll clean it up a bit too.
Cheers,
This patch creates a new function napi_poll and moves the napi
polling code from net_rx_action into it.

We should only perform the softnet_break check after we have polled
at least one device in net_rx_action. Otherwise a zero or negative
setting of netdev_budget can lock up the whole system.

This patch rearranges the loop in net_rx_action to reduce the
amount of jumping back and forth when reading the code.
