[net-next PATCH v2 0/4] Symmetric queue selection using XPS for Rx queues

[Amritha Nambiar]

This patch series implements support for Tx queue selection based on
Rx queue(s) map. This is done by configuring Rx queue(s) map per Tx-queue
using sysfs attribute. If the user configuration for Rx queues does
not apply, then the Tx queue selection falls back to XPS using CPUs and
finally to hashing.

XPS is refactored to support Tx queue selection based on either the
CPUs map or the Rx-queues map. The config option CONFIG_XPS needs to be
enabled. By default no receive queues are configured for the Tx queue.

- /sys/class/net/<dev>/queues/tx-*/xps_rxqs

This is to enable sending packets on the same Tx-Rx queue pair as this
is useful for busy polling multi-threaded workloads where it is not
possible to pin the threads to a CPU. This is a rework of Sridhar's
patch for symmetric queueing via socket option:
https://www.spinics.net/lists/netdev/msg453106.html

v2:
- Added documentation in networking/scaling.txt
- Added a simple routine to replace multiple ifdef blocks.

This looks like a bug fix, completely unrelated to the feature being added

into 'net-next' you can rebase this series on top of that.

Thank you.

[net-next PATCH v2 2/4] net: Enable Tx queue selection based on Rx queues

[Amritha Nambiar]

This patch adds support to pick Tx queue based on the Rx queue map
configuration set by the admin through the sysfs attribute
for each Tx queue. If the user configuration for receive
queue map does not apply, then the Tx queue selection falls back
to CPU map based selection and finally to hashing.

Isn't this increasing size of sock_common for a narrow use case functionality?

This while loop typifies exactly why I don't think the XPS maps should
be an array. There's only two and we really don't want this to be an
open ended invitation for people to create new mapping methods. The
code is much simpler and potentially more efficient if the two maps
are just separate pointers. It should look something like this:

dev_maps = rcu_dereference(dev->xps_rxqs_map);
if (dev_maps) {
        queue_index = __get_xps_queue_idx(dev, skb, dev_maps, tci);
        if (queue_index < 0) {
              dev_maps = rcu_dereference(dev->xps_rxqs_map);
              if (dev_maps) {
                     queue_index = __get_xps_queue_idx(dev, skb,
dev_rxqs_maps, tci);
               ...

Also, the rxqs is a pretty narrow use case and it's likely to be
rarely configured (relative to a CPU map). A static_key could be used
to eliminate the cost of the extra map check (the static_key could
also be used on for CPU maps, this is analogous to how there are
static keys for RPS and RFS).

You can get the device from the already recorded sk_napi_id.
Sadly, not the queue number as far as I can see.

Instead of adding this function and calls to it in many locations in
the stack, you can expand sk_mark_napi_id.

Also, it is not clear why this should be called in locations where
sk_mark_napi_id is not.

as a matter of fact, as enabling both cpu and rxqueue map at the same
time makes no sense, only one map is needed at any one time. The
only difference is in how it is indexed. It should probably not be possible
to configure both at the same time. Keeping a single map probably also
significantly simplifies patch 1/4.

Willem,

I think it might makes sense to have them both. Maybe one application
is spin polling that needs this, where others might be happy with
normal CPU mappings as default.

Some entries in the rx_queue table have queue_pair affinity
configured, the others return -1 to fall through to the cpu
affinity table?

I guess that implies flow steering to those special purpose
queues. I wonder whether this would be used this in practice.
I does make the code more complex by having to duplicate
the map lookup logic (mostly, patch 1/4).

That's a good pont. I think we need more information on how the
feature is going to be used in practice. My assumption is that there
are some number of "special" queues for which spin polling is being
done.

Yes, by default, rx queue maps are not configured for the tx queue.
These maps have to be explicitly configured mapping rx queue(s) to tx
queue(s). If the rx queue map configuration does not apply, then the tx
queue is selected based on the CPUs map.

I plan to not have the ifindex cached in the sock_common, but retain the
rx_queue only. This way, it'll look similar to skb_tx_hash where
rx_queue recorded is used and if not, fall through to flow hash
calculation. Likewise, we use the rx_queue mapped and fall through to
CPU map on failures.

[net-next PATCH v2 3/4] net-sysfs: Add interface for Rx queue map per Tx queue

If I'm reading the patch correctly, isn't this mapping rxq to a set of
txqs (in other words not strictly queue pair which has other
connotations in NIC HW). It is important to make it clear that this
feature is no HW dependent.

Please add something about how this was tested and what the
performance gain is to justify the feature.
