Message-ID: <55FB226F.2040707@linaro.org> (raw)
Hi,
The recv function does a prefetch on cacheline1, however it seems to me
that rx_pkts[pos] should be uninitialized pointer at that time:
http://dpdk.org/browse/dpdk/tree/drivers/net/ixgbe/ixgbe_rxtx_vec.c#n287
So I guess it prefetches only random value. Or am I missing something?
Regards,
Zoltan
