app/testpmd: fix queue stats mapping configuration

Currently, the queue stats mapping has the following problems:
1) Many PMD drivers don't support queue stats mapping. But there is no
   failure message after executing the command "set stat_qmap rx 0 2 2".
2) Once queue mapping is set, unrelated and unmapped queues are also
   displayed.
3) The configuration result does not take effect or can not be queried
   in real time.
4) The mapping arrays, "tx_queue_stats_mappings_array" &
   "rx_queue_stats_mappings_array" are global and their sizes are based
   on fixed max port and queue size assumptions.
5) These record structures, 'map_port_queue_stats_mapping_registers()'
   and its sub functions are redundant for majority of drivers.
6) The display of the queue stats and queue stats mapping is mixed
   together.

Since xstats is used to obtain queue statistics, we have made the
following simplifications and adjustments:
1) If PMD requires and supports queue stats mapping, configure to driver
   in real time by calling ethdev API after executing the command "set
   stat_qmap rx/tx ...". If not, the command can not be accepted.
2) Based on the above adjustments, these record structures,
   'map_port_queue_stats_mapping_registers()' and its sub functions can
   be removed. "tx-queue-stats-mapping" & "rx-queue-stats-mapping"
   parameters, and 'parse_queue_stats_mapping_config()' can be removed
   too.
3) remove display of queue stats mapping in 'fwd_stats_display()' &
   'nic_stats_display()', and obtain queue stats by xstats.  Since the
   record structures are removed, 'nic_stats_mapping_display()' can be
   deleted.

for testing and measure those rates using flow-perf application.

Now we generate cores and distribute all flows to those cores,
and start inserting/deleting in parallel.

The app now receive the cores count to use from command line option,
then it distribute the rte_flow rules evenly between the cores, and
start inserting/deleting. Each worker will report it's own results,
and in the end the MAIN worker will report the total results for all
cores.

The total results are calculated using RULES_COUNT divided over
max time used between all cores.

Also this touches the memory area, since inserting using multiple cores
in same time the pre solution for memory is not valid, thus now we save
memory before and after each allocation for all cores. In the end we
pick the min pre memory and the max post memory from all cores.

The difference between those values represent the total memory consumed
by the total rte_flow rules from all cores, and then report the total
size of single rte_flow in byte for each port.

ci: enable v21 ABI checks

v21 ABI will be maintained until v21.11.

Let's use the latest released libabigail 1.8.

In GitHub Actions, libabigail binaries and the ABI reference are stored
in two shared caches as all branches can use the same.

While at it, we can reproduce changes from the commit 0b8086ce3fe7
("devtools: remove useless files from ABI reference").
This will save some space in the CI caches.

3 years agoci: hook to GitHub Actions
David Marchand [Fri, 4 Dec 2020 17:36:21 +0000 (18:36 +0100)]
ci: hook to GitHub Actions

With the recent changes in terms of free access to the Travis CI, let's
offer an alternative with GitHub Actions.
Running jobs on ARM is not supported unless using external runners, so
this commit only adds builds for x86_64 and cross compiling for i386 and
aarch64.

Differences with the Travis CI integration:
- Error logs are not dumped to the console when something goes wrong.
  Instead, they are gathered in a "catch-all" step and attached as
  artifacts.
- A cache entry is stored once and for all, but if no cache is found you
  can inherit from the default branch cache. The cache is 5GB large, for
  the whole git repository.
- The maximum retention of logs and artifacts is 3 months.
- /home/runner is world writable, so a workaround has been added for
  starting dpdk processes.
- Ilya, working on OVS GHA support, noticed that jobs can run with
  processors that don't have the same capabilities. For DPDK, this
  impacts the ccache content since everything was built with
  -march=native so far, and we will end up with binaries that can't run
  in a later build. The problem has not been seen in Travis CI (?) but
  it is safer to use a fixed "-Dmachine=default" in any case.
- Scheduling jobs is part of the configuration and takes the form of a
  crontab. A build is scheduled every Monday at 0:00 (UTC) to provide a
  default ccache for the week (useful for the ovsrobot).

doc: announce flow API matching structs changes

Proposing to replace protocol header fields in the ``rte_flow_item_*``
structures with the protocol structs.

This is both for documenting the intention and to be sure
``rte_flow_item_*`` always starts with complete protocol header.

Change will be done in two steps, at first step in v21.02 release,
protocol header struct will be added as union, for example:

Current ``struct rte_flow_item_eth``,

struct rte_flow_item_eth {
struct rte_ether_addr dst;
struct rte_ether_addr src;
rte_be16_t type;
uint32_t has_vlan:1;
uint32_t reserved:31;
}

will become in v21.02:

__extension__
struct rte_flow_item_eth {
union {
struct {
struct rte_ether_addr dst;
struct rte_ether_addr src;
rte_be16_t type;
};
struct rte_ether_hdr hdr;
};
uint32_t has_vlan:1;
uint32_t reserved:31;
}

After this point usage should switch to 'hdr' struct.

And in the second step, in the v21.11 LTS release the protocol fields
will be removed, and the struct will become:

struct rte_flow_item_eth {
struct rte_ether_hdr hdr;
uint32_t has_vlan:1;
uint32_t reserved:31;
}

Already many ``rte_flow_item_*`` structures implemented to have protocol
struct, target is convert all to this usage.

doc: update flow API guide for rule removal on stop

There is a discrepancy between ethdev API and flow rules guide
regarding flow rules maintenance after port stop.
librte_ethdev.h declares that flow rules will not be stored in PMD
after port stop:
>>>>> Quote start
 Please note that some configuration is not stored between calls to
 rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration
 will be retained:

 - MTU
 - flow control settings
 - receive mode configuration (promiscuous mode, all-multicast mode,
   hardware checksum mode, RSS/VMDQ settings etc.)
 - VLAN filtering configuration
 - default MAC address
 - MAC addresses supplied to MAC address array
 - flow director filtering mode (but not filtering rules)
 - NIC queue statistics mappings
<<<< Quote end

PMD cannot always correctly restore flow rules after port stop / port
start because application may alter port configuration after port stop
without PMD knowledge about undergoing changes.  Consider the
following scenario:
application configures 2 queues 0 and 1 and creates a flow rule with
'queue index 1' action. After that application stops the port and
removes queue 1.
Although PMD can implement flow rule shadow copy to be used for
restore after port start, attempt to restore flow rule from shadow
will fail in example above and PMD could not notify application about
that failure.  As the result, flow rules map in HW will differ from
what application expects.  In addition, flow rules shadow copy used
for port start restore consumes considerable amount of system memory,
especially in systems with millions of flow rules.

Replace the rte_flow_item_* with the existing corresponding rte_*_hdr.

3 years agousertools: add huge page setup script
Stephen Hemminger [Wed, 9 Sep 2020 18:51:01 +0000 (11:51 -0700)]
usertools: add huge page setup script

This is an improved version of the setup of huge pages
bases on earlier DPDK setup.

Differences are:
   * autodetects NUMA vs non NUMA
   * allows setting different page sizes
     recent kernels support multiple sizes.
   * accepts a parameter in bytes (not pages).
   * can display current hugepage settings.

Most users will just use --setup argument but if necessary
the steps of clearing old settings and mounting/umounting
can be done individually.

3 years agousertools: fix pmdinfo parsing
Julien Massonneau [Thu, 19 Nov 2020 09:44:01 +0000 (10:44 +0100)]
usertools: fix pmdinfo parsing

In the display_pmd_info_strings function, the script parses the section
until to find a byte between 32 and 127, and get all data
until a byte equals to 0.
After, it searches "PMD_INFO_STRING" in the data and passes the whole
string in the parse_pmd_info_string function, which split the string
with "=" and convert it in python dict with json.loads().

But the string may contain a "=" before "PMD_INFO_STRING",
so it is not correctly split and will lead to an error
(json.decoder.JSONDecodeError).

Example of a string encountered that leads to an error:

"Ag%=C£°ÐÊ+Ë®{0´wË-£0òjB·;¾¬úPMD_INFO_STRING= {"name" :
"net_octeontx", "params" : "nr_port=<int> ", "pci_ids" : []}"
