4 years agosched: fix port time rounding
Alan Dewar [Thu, 25 Jun 2020 09:59:30 +0000 (10:59 +0100)]
sched: fix port time rounding

The QoS scheduler works off port time that is computed from the number
of CPU cycles that have elapsed since the last time the port was
polled.   It divides the number of elapsed cycles to calculate how
many bytes can be sent, however this division can generate rounding
errors, where some fraction of a byte sent may be lost.

Lose enough of these fractional bytes and the QoS scheduler
underperforms.  The problem is worse with low bandwidths.

To compensate for this rounding error this fix doesn't advance the
port's time_cpu_cycles by the number of cycles that have elapsed,
but by multiplying the computed number of bytes that can be sent
(which has been rounded down) by number of cycles per byte.
This will mean that port's time_cpu_cycles will lag behind the CPU
cycles momentarily.  At the next poll, the lag will be taken into
account.

RegEx: A regular expression is a concise and flexible means for matching
strings of text, such as particular characters, words, or patterns of
characters. A common abbreviation for this is â~@~\RegExâ~@~].

RegEx device: A hardware or software-based implementation of RegEx
device API for PCRE based pattern matching syntax and semantics.

PCRE RegEx syntax and semantics specification:
http://regexkit.sourceforge.net/Documentation/pcre/pcrepattern.html

RegEx queue pair: Each RegEx device should have one or more queue pair to
transmit a burst of pattern matching request and receive a burst of
receive the pattern matching response. The pattern matching
request/response embedded in *rte_regex_ops* structure.

Rule: A pattern matching rule expressed in PCRE RegEx syntax along with
Match ID and Group ID to identify the rule upon the match.

Rule database: The RegEx device accepts regular expressions and converts
them into a compiled rule database that can then be used to scan data.
Compilation allows the device to analyze the given pattern(s) and
pre-determine how to scan for these patterns in an optimized fashion that
would be far too expensive to compute at run-time. A rule database
contains a set of rules that compiled in device specific binary form.

Match ID or Rule ID: A unique identifier provided at the time of rule
creation for the application to identify the rule upon match.

Group ID: Group of rules can be grouped under one group ID to enable
rule isolation and effective pattern matching. A unique group identifier
provided at the time of rule creation for the application to identify
the rule upon match.

Scan: A pattern matching request through *enqueue* API.

It may possible that a given RegEx device may not support all the
features
of PCRE. The application may probe unsupported features through
struct rte_regexdev_info::pcre_unsup_flags

By default, all the functions of the RegEx Device API exported by a PMD
are lock-free functions which assume to not be invoked in parallel on
different logical cores to work on the same target object. For instance,
the dequeue function of a PMD cannot be invoked in parallel on two logical
cores to operates on same RegEx queue pair. Of course, this function
can be invoked in parallel by different logical core on different queue
pair. It is the responsibility of the upper level application to
enforce this rule.

In all functions of the RegEx API, the RegEx device is
designated by an integer >= 0 named the device identifier *dev_id*

At the RegEx driver level, RegEx devices are represented by a generic
data structure of type *rte_regexdev*.
RegEx devices are dynamically registered during the PCI/SoC device
probing phase performed at EAL initialization time.
When a RegEx device is being probed, a *rte_regexdev* structure and
a new device identifier are allocated for that device. Then, the
regexdev_init() function supplied by the RegEx driver matching the
probed device is invoked to properly initialize the device.

The role of the device init function consists of resetting the hardware
or software RegEx driver implementations.

If the device init operation is successful, the correspondence between
the device identifier assigned to the new device and its associated
*rte_regexdev* structure is effectively registered.
Otherwise, both the *rte_regexdev* structure and the device identifier
are freed.

The functions exported by the application RegEx API to setup a device
designated by its device identifier must be invoked in the following
order:
    - rte_regexdev_configure()
    - rte_regexdev_queue_pair_setup()
    - rte_regexdev_start()

Then, the application can invoke, in any order, the functions
exported by the RegEx API to enqueue pattern matching job, dequeue
pattern matching response, get the stats, update the rule database,
get/set device attributes and so on

If the application wants to change the configuration (i.e. call
rte_regexdev_configure() or rte_regexdev_queue_pair_setup()), it must
call rte_regexdev_stop() first to stop the device and then do the
reconfiguration before calling rte_regexdev_start() again. The enqueue and
dequeue functions should not be invoked when the device is stopped.

Finally, an application can close a RegEx device by invoking the
rte_regexdev_close() function.

Each function of the application RegEx API invokes a specific function
of the PMD that controls the target device designated by its device
identifier.

For this purpose, all device-specific functions of a RegEx driver are
supplied through a set of pointers contained in a generic structure of
type *regexdev_ops*.
The address of the *regexdev_ops* structure is stored in the
*rte_regexdev* structure by the device init function of the RegEx driver,
which is invoked during the PCI/SoC device probing phase, as explained
earlier.

In other words, each function of the RegEx API simply retrieves the
*rte_regexdev* structure associated with the device identifier and
performs an indirect invocation of the corresponding driver function
supplied in the *regexdev_ops* structure of the *rte_regexdev*
structure.

For performance reasons, the address of the fast-path functions of the
RegEx driver is not contained in the *regexdev_ops* structure.
Instead, they are directly stored at the beginning of the *rte_regexdev*
structure to avoid an extra indirect memory access during their
invocation.

RTE RegEx device drivers do not use interrupts for enqueue or dequeue
operation. Instead, RegEx drivers export Poll-Mode enqueue and dequeue
functions to applications.

The *enqueue* operation submits a burst of RegEx pattern matching
request to the RegEx device and the *dequeue* operation gets a burst of
pattern matching response for the ones submitted through *enqueue*
operation.

Typical application utilisation of the RegEx device API will follow the
following programming flow.

- rte_regexdev_configure()
- rte_regexdev_queue_pair_setup()
- rte_regexdev_rule_db_update() Needs to invoke if precompiled rule
  database not
  provided in rte_regexdev_config::rule_db for rte_regexdev_configure()
  and/or application needs to update rule database.
- rte_regexdev_rule_db_compile_activate() Needs to invoke if
  rte_regexdev_rule_db_update function was used.
- Create or reuse exiting mempool for *rte_regex_ops* objects.
- rte_regexdev_start()
- rte_regexdev_enqueue_burst()
- rte_regexdev_dequeue_burst()

Bruce Richardson [Fri, 26 Jun 2020 14:59:57 +0000 (15:59 +0100)]
eal: restrict default plugin path to shared lib mode

When using statically linked DPDK binaries, the EAL checks the default PMD
path and tries to load any drivers there, despite the fact that all drivers
are normally linked into the binary.  This behaviour can cause issues if
the PMD path and lib dir is configured to a non-standard location which is
not in the ld.so.conf paths, e.g. a build with prefix set to a home
directory location. In a case such as this, EAL will try and
(unnecessarily) load the .so driver files but that load will fail as their
dependent libraries, such as ethdev, for example, will not be found.

Because of this, it is better if statically linked DPDK apps do not load
drivers from the standard paths automatically. The user can always have
this behaviour by explicitly specifying the path using -d flag, if so
desired.

Not loading the libraries automatically can also prevent potential issues
with a user building and running a statically-linked DPDK binary based off
a private copy of DPDK, while there exists on the same machine a
system-wide installation of DPDK in the default locations. Without this
change, the system-installed drivers will be loaded to the binary alongside
the statically-linked drivers, which is not what the user would have
intended.

To detect whether we are in a statically or dynamically linked binary, we
can have EAL try to get a dlopen handle to its own shared library, by
calling dlopen with the RTLD_NOLOAD flag. This will return NULL if there is
no such shared lib loaded i.e. the code is executing from a static library,
or a handle to the lib if it is loaded.

build/pkg-config: output drivers first for static build

When calling pkg-config --static --libs, pkg-config will always output the
regular libs first, and then the extra libs from Libs.private field,
since the assumption is that those are additional dependencies for building
statically that the .a files depend upon.

However, for DPDK, we only link the driver files for static builds, and
those need to come *before* the regular libraries. To get this result, we
need two pkgconfig files for DPDK, one for the shared libs, and a second
for the static libs and drivers, which depends upon the first. Using a
dependency means that the shared libs are printed only after the
Libs.private field rather than before.

Without this patch, the linking works in DPDK because in all cases we
specify the libraries after the drivers in the Libs.private line, ensuring
that the references to the libs from the drivers can be resolved. The
current output is therefore of the form, "(shared)libs, drivers,
(static)libs", while after this patch the output is, "drivers,
(static)libs, (shared)libs". The former case will not work if we use the
--whole-archive flag on the static libs as it will lead to duplicate
definitions due to some references having been previously resolved from the
shared libraries. By ensuring the shared libraries come last in the link
link, this issue does not occur, as duplicate references when linking the
shared libs will be ignored.

net/af_xdp: improve packet loss

This commit makes some changes to the AF_XDP PMD in an effort to improve
its packet loss characteristics.

1. In the case of failed transmission due to inability to reserve a tx
   descriptor, the PMD now pulls from the completion ring, issues a
   syscall in which the kernel attempts to complete outstanding tx
   operations, then tries to reserve the tx descriptor again. Prior to
   this we dropped the packet after the syscall and didn't try to
   re-reserve.

2. During completion ring cleanup, always pull as many entries as
   possible from the ring as opposed to the batch size or just how many
   packets we're going to attempt to send. Keeping the completion ring
   emptier should reduce failed transmissions in the kernel, as the
   kernel requires space in the completion ring to successfully tx.

3. Size the fill ring as twice the receive ring size which may help
   reduce allocation failures in the driver.

4. Emulate a tx_free_thresh - when the number of available entries in
   the completion ring rises above this, we pull from it. The threshold
   is set to 1k entries.

With these changes, a benchmark which measured the packet rate at which
0.01% packet loss could be reached improved from ~0.1G to ~3Gbps.
