ixgbe: fix crash caused by bulk allocation failure

Since the introduction of vector PMD, a bug in ixgbe_rxq_rearm could
cause a crash. As long as the memory pool allocated to the RX queue
has mbufs available, there is no problem. After allocation of _all_
mbufs from the memory pool, previously returned mbufs by
rte_eth_rx_burst could be accessed by subsequent calls to the PMD and
could be returned by subsequent calls to rte_eth_rx_burst. From the
perspective of the application, the means that fields within the mbuf
could change and that previously allocated mbufs could appear multiple
times.

After failure of mbuf allocation, the dd bits should indicate that the
packets are not ready. For this, this patch adds code to reset the dd
bits in the first RTE_IXGBE_DESCS_PER_LOOP packets of the next
RTE_IXGBE_RXQ_REARM_THRESH packets only if the next
RTE_IXGBE_RXQ_REARM_THRESH packets that will be accessed contain
previously allocated packets.

Setting the bits is not enough. The bits are checked _after_ setting
the mbuf fields, thus a mechanism is needed to prevent the previously
used mbuf pointers from being accessed during the speculative load of
the mbuf fields. For this reason, not only the dd bits are reset, but
also the mbufs associated to those descriptors are set to point to a
"fake" mbuf.

This change splits the mbuf in two to move the pool and next pointers to

If we accept the fact of a 2-cache-line mbuf, then the issue becomes
how to rework things so that we spread our fields over the two
cache lines while causing the lowest slow-down possible. The general
approach that we are looking to take is to focus the first cache
line on fields that are updated on RX , so that receive only deals
with one cache line. The second cache line can be used for application
data and information that will only be used on the TX leg. This would
allow us to work on the first cache line in RX as now, and have the
second cache line being prefetched in the background so that it is
available when necessary. Hardware prefetches should help us out
here. We also may move rarely used, or slow-path RX fields e.g. such
as those for chained mbufs with jumbo frames, to the second
cache line, depending upon the performance impact and bytes savings
achieved.

9 years agombuf: add named points inside the structure
Bruce Richardson [Thu, 11 Sep 2014 13:15:42 +0000 (14:15 +0100)]
mbuf: add named points inside the structure

Add markers or "labels" at given points inside the mbuf which can be
used instead of individual fields to identify the start of logical
sections inside the mbuf.

The use of typedefs and dummy fields was chosen over using unions
because of a couple reasons:
* unions cause an extra level of indentation (more likely two levels as
  a union containing a struct for multiple fields would be needed). This
  makes the lines longer than they need to be and increases the need for
  wrapping. [This was the main reason]
* with markers, you can apply multiple markers at the same point if
  wanted.

mbuf: flatten struct vlan_macip

The vlan_macip structure combined a vlan tag id with l2 and l3 headers
lengths for tracking offloads. However, this structure was only used as
a unit by the e1000 and ixgbe drivers, not generally.

This patch removes the structure from the mbuf header and places the
fields into the mbuf structure directly at the required point, without
any net effect on the structure layout. This allows us to treat the vlan
tags and header length fields as separate for future mbuf changes. The
drivers which were written to use the combined structure still do so,
using a driver-local definition of it.

Reduce perf regression caused by splitting vlan_macip field. This is
done by providing a single uint16_t value to allow writing/clearing
the l2 and l3 lengths together. There is still a small perf hit to the
slow path TX due to the reads from vlan_tci and l2/l3 lengths being
separated. (<5% in my tests with testpmd with no extra params).
Unfortunately, this cannot be eliminated, without restoring the vlan
tags and l2/l3 lengths as a combined 32-bit field. This would prevent
us from ever looking to move those fields about and is an artificial tie
that applies only for performance in igb and ixgbe drivers. Therefore,
this patch keeps the vlan_tci field separate from the lengths as the
best solution going forward.
