Marc Sune [Tue, 21 Oct 2014 10:46:55 +0000 (12:46 +0200)]
kni: memzone pool for alloc and release

The previous implementation of rte_kni_alloc() was allocating memzones with a
name composed of a fixed string and the interface name. When an application was
allocating and deallocating multiple interfaces with different names, memzones
were quickly exhausted, even though memzones from deallocated interfaces were
never used anymore (unless an interface with the same name was re-allocated).
As a result, the application was unable to allocate more KNI interfaces with
different names.

This patch implements the KNI memzone pool in order to prevent memzone
exhaustion when allocating/deallocating KNI interfaces. It adds a new API call,
rte_kni_init(max_kni_ifaces) that shall be called before any call to
rte_kni_alloc() if KNI is used. The memzones are pre-allocated with interface-
independent names so that they can be reused.

ixgbe: add prefetch to improve slow-path tx perf

Make a small improvement to slow path TX performance by adding in a
prefetch for the second mbuf cache line.
Also move assignment of l2/l3 length values only when needed.

What I've done with the prefetches is two-fold:
1) changed it from prefetching the mbuf (first cache line) to prefetching
the mbuf pool pointer (second cache line) so that when we go to access
the pool pointer to free transmitted mbufs we don't get a cache miss. When
clearing the ring and freeing mbufs, the pool pointer is the only mbuf
field used, so we don't need that first cache line.
2) changed the code to prefetch earlier - in effect to prefetch one mbuf
ahead. The original code prefetched the mbuf to be freed as soon as it
started processing the mbuf to replace it. Instead now, every time we
calculate what the next mbuf position is going to be we prefetch the mbuf
in that position (i.e. the mbuf pool pointer we are going to free the mbuf
to), even while we are still updating the previous mbuf slot on the ring.
This gives the prefetch much more time to resolve and get the data we need

mbuf: switch vlan_tci and reserved2 fields

Move the vlan_tci field up by two bytes in the mbuf data structure. This
has two effects:
* Ensures the the ixgbe vector driver places the vlan tag in the correct

mbuf: add userdata pointer field

While some applications may store metadata about packets in the packet
mbuf headroom, this is not a workable solution for packet metadata which
is either:
* larger than the headroom (or headroom is needed for adding pkt headers)
* needs to be shared or copied among packets

To support these use cases in applications, we reserve a general
"userdata" pointer field inside the second cache-line of the mbuf. This
is better than having the application store the pointer to the external
metadata in the packet headroom, as it saves an additional cache-line
from being used.

Apart from storing metadata, this field also provides a general 8-byte
scratch space inside the mbuf for any other application uses that are
applicable.

i40e/base: fix arq_event_info struct

Overloading the 'msg_size' field in the 'arq_event_info' struct
is a bad idea. It leads to bugs when the structure is used in a
loop, since the input value (buffer size) is overwritten by the
output value (actual message length). The fix introduces one
more field of 'buf_len' for the buffer size, and renames the
field of 'msg_size' to 'msg_len' for the real message size.
