Xen users - Feb 2013 - pv driver with NAPI support

hello,

I tried using NAPI in pv network drivers, but i discovered that it
don''t
supports NAPI (kernel 3.5.0-17, xen 4.3.1).

I like to know if any version of pv driver supports NAPI

regards
Eduardo

Netfront already uses NAPI but netback does not. There was a
experimental netback implementation with NAPI and other stuffs, but it
is not yet ready for upstream.

Just asking, what''s the motivation for you to use NAPI? Do you see
bottleneck in current implementation?

Hi Wei,

i''m doing experiments with interrupt coalescence trying to find good
values
that increase bandwidth and reduce the amount of interruptions
