Bruce Richardson [Thu, 14 Apr 2016 16:02:37 +0000 (17:02 +0100)]
i40e: simplify SSE packet length extraction code

In Table 8-16 of the "Intel® Ethernet Controller XL710 Datasheet" it is
stated that when the whole packet is written to a single buffer, the
header length field in the descriptor will be 0. This means that when
extracting the packet/data_len field from the descriptor in the driver
we do not need to mask out the extra header-length bits.

Inside the vector driver, this reduces the need to pull all four pktlen
fields into a single register to work on. Instead of a shift and mask,
we now need to only do a shift. Therefore, we can work on each descriptor
independently, processing each using one shift intrinsic and a blend.

This change makes the code shorter and easier to read, so we can pull it
into the main descriptor processing loop instead of needing its own
function. This in turn makes the descriptor processing in the loop as a
whole slightly easier to read as it's more linear.

In terms of performance, in testing this change shows little effect, with
single-core perf tests showing a very slight improvement.

Bruce Richardson [Thu, 14 Apr 2016 16:02:36 +0000 (17:02 +0100)]
i40e: improve performance of vector PMD

An analysis of the i40e code using Intel® VTune™ Amplifier 2016 showed
that the code was unexpectedly causing stalls due to "Loads blocked by
Store Forwards". This can occur when a load from memory has to wait
due to the prior store being to the same address, but being of a smaller
size i.e. the stored value cannot be directly returned to the loader.
[See ref: https://software.intel.com/en-us/node/544454]

These stalls are due to the way in which the data_len values are handled
in the driver. The lengths are extracted using vector operations, but those
16-bit lengths are then assigned using scalar operations i.e. 16-bit
stores.

These regular 16-bit stores actually have two effects in the code:
* they cause the "Loads blocked by Store Forwards" issues reported
* they also cause the previous loads in the RX function to actually be a
load followed by a store to an address on the stack, because the 16-bit
assignment can't be done to an xmm register.

By converting the 16-bit store operations into a sequence of SSE blend
operations, we can ensure that the descriptor loads only occur once, and
avoid both the additional stores and loads from the stack, as well as the
stalls due to the blocked loads.

lpm: fix freeing in compatibility mode

Back then when we fixed the missing free lpm I was to quickly to say yes
if it applies not only to the lpm6 but also to all of the lpm code.

It turned out to not apply to all of them. In rte_lpm_create_v20 there
is an unexpected fused allocation:
mem_size = sizeof(*lpm) + (sizeof(lpm->rules_tbl[0]) * max_rules);
[...]
lpm = (struct rte_lpm_v20 *)rte_zmalloc_socket(mem_name,mem_size,
               RTE_CACHE_LINE_SIZE, socket_id);

That causes lpm->rules_tbl not to have an own struct malloc_elem that
can be derived via RTE_PTR_SUB(data, MALLOC_ELEM_HEADER_LEN) in
malloc_elem_from_data.
Due to that the rte_lpm_free_v20 accidentially misderives the elem and
assumes it is ELEM_FREE triggering in malloc_elem_free
if (!malloc_elem_cookies_ok(elem) || elem->state !=
        return -1;

While it seems counter-intuitive the way to properly remove rules_tbl in
the old fused allocation style of rte_lpm_free_v20 is to not remove it.

The newer rte_lpm_free_v1604 is safe because in rte_lpm_create_v1604
rules_tbl is a separate allocation.

doc: announce API changes for vhost refactoring

We currently exposed way too many fields (or even structures) than
necessary. For example, vhost_virtqueue struct should NOT be exposed
to user at all: application just need to tell the right queue id to
locate a specific queue, and that's all. Instead, the structure should
be defined in an internal header file. With that, we could do any changes
to it we want, without worrying about that we may offense the painful
ABI rules.

Similar changes could be done to virtio_net struct as well, just exposing
very few fields that are necessary and moving all others to an internal
structure.

Huawei then suggested a more radical yet much cleaner one: just exposing
a virtio_net handle to application, just like the way kernel exposes an
fd to user for locating a specific file, and exposing some new functions
to access those old fields, such as flags, virt_qp_nb.

With this change, we're likely to be free from ABI violations forever
(well, except when we have to extend the virtio_net_device_ops struct).
For example, following nice cleanup would not be a blocking one then:

ixgbe: fix packet type for VXLAN and NVGRE on X550

VxLAN & NVGRE are supported by x550. As we know HW can parse
the packet and tell SW the type info. For VxLAN & NVGRE packets
there's some change. HW will not tell SW the info of the outer
header but the inner header instead. But we always take the
info as it's for the outer header. So the packet type info is
not right when x550 receives VxLAN & NVGRE packets.

As x550 only supports IPv4 VxLAN & NVGRE packets, we can tell
the outer header of VxLAN is IPv4 + UDP, and the outer header
of NVGRE is IPv4 only. What we don't know is if there's
optional field in the outer IPv4 header.

This patch implement the support of packet type for VxLAN &
NVGRE. And it fixes the wrong packet type issue either.

BTW:
It doesn't fix any existing commit as although it resolve an
issue it's more like a new feature but not a fix.
