Add 'system:cpu_hz_static' configuration option for using a static CPU
frequency value. When enabled, CPU frequency values returned by
odp_cpu_hz() and odp_cpu_hz_id() calls are read from the OS only once
during ODP initialization. Enabling this option removes system calls from
odp_cpu_hz() and odp_cpu_hz_id() implementations.
NOTE: This option should only be used on systems where CPU frequency
scaling is disabled.

Estimate current load on a spread ring as number of queues
allocated to it divided by number of threads preferring the
spread. Each thread runs a series of spread load balance
checks starting at every 1M schedule calls.
This helps especially when there are less threads in a group
than the number of spreads configured. Scheduler moves more
queues to those spread rings that have more thread capacity.
This works best when all threads and queues are equally active.

Add new config file parameters to control how original input queue
order is maintained during asynchronous IPsec processing.
When asynchronous IPsec operations are started within an ordered
scheduling context, packet order is maintained in IPsec completion
queues but the order in which the sequence number gets assigned or
the anti-replay check done is not guaranteed. This commit adds a config
option to force the stateful part of IPsec processing to be done in the
correct order, at the cost of reduced parallelism.
The ordering mechanism added in this commit uses the order_lock method
of the internal scheduling API to stop the calling thread until it
is its turn (i.e the preceding scheduling contexts associated with the
same input queue have been released). Future commits may add more
elaborate mechanisms.
The default behaviour does not change. By default no ordering is done.

Add system:thread_count_max config parameter that can be used to reduce
the maximum number of threads below the build time configured maximum.
This can be used to reduce thread related resource consumption such
as thread-local memory.
Most code still uses the build time limit, ODP_THREAD_COUNT_MAX, so this
change merely enables possible later optimizations in those cases.
ODP-DPDK will already benefit from this change as the number of queue
pairs for a crypto device can be lowered to match the actual number of
threads without ODP-DPDK having worry about possible sharing of the
queue pairs between threads.

With this patch, ODP will pre-allocate several huge pages at init
time. When memory is to be mapped into a huge page, one that was
pre-allocated will be used, if available, this way ODP won't have to
trap into the kernel to allocate huge pages.
The idea with this implementation is to trick ishm into thinking that
a file descriptor where to map the memory was provided, this way it
it won't try to allocate one itself. This file descriptor is one of
those previously allocated at init time. When the system is done with
this file descriptor, instead of closing it, it is put back into the
list of available huge pages, ready to be reused.
A collateral effect of this patch is that memory is not zeroed out
when it is reused.
WARNING: This patch will not work when using process mode threads.
For several reasons, this may not work when using ODP_ISHM_SINGLE_VA
either, so when this flag is set, the list of pre-allocated files is
not used.
By default ODP will not reserve any huge pages, to tell ODP to do that,
update the ODP configuration file with something like this:
shm: {
num_cached_hp = 32
}
Example usage:
$ echo odp.config
odp_implementation = "linux-generic"
config_file_version = "0.0.1"
shm: {
num_cached_hp = 32
}
$ ODP_CONFIG_FILE=odp.conf ./test/validation/api/shmem/shmem_main

Make default burst sizes configurable. User can set limits for
burst size round up in high/low priority. When less than
burst_size_xx events are requested, scheduler rounds up the
number of events to these limit and stash extra events. Requests
with more events are not round down. So, user can use small
values in burst size configure for better real-time support, but
still request large number of events for better throughput on
non real-time threads.

ODP includes big blocks of License headers in all files. This not
only blows up the source code with mostly redundant information, but
also makes it very difficult to generate License Clearing Reports.
An additional problem is that even the same licenses are referred to
by a number of slightly varying text blocks (full, abbreviated, different
indentation, line wrapping and/or white space, with obsolete address
information, ...) which makes automatic processing a nightmare.
To make this easier, such license headers in the source files will be
replaced with a single line reference to Unique License Identifiers
as defined by the Linux Foundation's SPDX project [1]. I.e,
in a source file the full BSD 3-clause header text will be
replaced by a single line:
SPDX-License-Identifier: BSD-3-Clause
We use the SPDX Unique License Identifiers here; these are available
at [2].
Note: From the legal point of view, this patch is supposed to be only
a change to the textual representation of the license information,
but in no way any change to the actual license terms. With this patch
applied, all files will still be licensed under the same terms they
were before.
