Long term stable monarch release for odp-dpdk
linux-dpdk: pool: check pool name length DPDK only supports RTE_MEMPOOL_NAMESIZE, this patch trims the name, and warns about name collision. Signed-off-by: Zoltan Kiss <zoltan.kiss@linaro.org>
== OpenDataPlane (1.10.1.0) === New Features ==== APIs ODP v1.10.1.0 is a maintenance release and as such introduces no new APIs or other changes that might result in application source incompatibility with v1.10.0.0. ==== Modular Scheduler The ODP scheduler included as part of the `odp-linux` reference implementation has been modularized to support a "pluggable" architecture that will permit the easy introduction of alternate scheduler implementations that permit both easy experimentation as well as alternate scheduling models that are tuned to specific application workloads (_i.e.,_ a strict priority scheduler for latency-sensitive workloads). Included in this release is the just the foundation and alternate schedulers are expected to be added in future ODP releases. === Packaging ==== Rename of `linux-generic` to `odp-linux` While the platform name within the ODP git repository remains `linux-generic`, the package name of this reference implementation has been changed to `odp-linux` to better reflect that this is an implementation of ODP that is dependent only on the Linux kernel and is intended to be runnable on any Linux distribution. All ODP documentation has been changed to reflect this name change. === Helpers ==== Introduction of "agnostic" threading support The current helper APIs for linux pthreads (`odph_linux_pthread_create()`, etc.) and processes (`odph_linux_process_fork()`, etc.) have been augmented with a new "agnostic" set of helper routines for general ODP thread management. `odph_odpthreads_create()` and `odph_odpthreads_join()` are now the preferred helpers to use for creating and joining threads that may be implemented as _either_ pthreads or Linux processes. Although currently ODP threads in Monarch are assumed to share the same (single) address space, this change is to permit evolution towards multi-address space (_i.e.,_ process oriented) threading models without requiring application and/or validation test changes. The various ODP examples and validation tests that make use of threading have all been changed to new these new helper APIs. ==== Thread affinity APIs As part of the new "agnostic" threading support, two additional helper APIs (`odph_odpthread_getaffinity()` and `odph_odpthread_setaffinity()`) have been added to permit easy management of thread affinity. The CUnit framework used by the ODP validation suite has been changed to set the affinity of the initial thread to the first available control CPU. This avoids inconsistencies in a number of timing tests. === Bug Fixes As a maintenance release, numerous bugs have been fixed in the `odp-linux` reference implementation in areas such as platform support (particularly on 32-bit systems), compiler support (clang), C++ compatibility, and other cleanup items. Highlights include: ==== 32-bit platform support The `configure` utility now correctly identifies and sets variables needed for proper compilation on 32-bit x86 systems. In addition the Traffic Manager now executes properly on 32-bit systems. ==== Timer improvements The `odp_timer_t` abstract type is now strongly typed for consistency with other ODP types, and the `odp_timer_to_u64()` and `odp_timer_pool_to_u64()` APIs are now properly implemented. In addition, an issue with compiling the timer routines on 32-bit systems using clang was resolved. ==== Scheduler fairness The default scheduler has been improved to avoid starvation and increase fairness when running with a limited number of threads or CPUs. ==== 128-bit atomics The `-mcx16` compiler option is now properly identified and used to support 128-bit atomics on systems that support these operations. This leads to increased efficiency in the implementation of both timers as well as other atomic operations. ==== Use of hugepages In systems that support multiple hugepage sizes, the default hugepage size is now reported properly by the `odp_sys_huge_page_size()` API. ==== Coverity and Valgrind issue cleanup Numerous issues identified by the Coverity scan tool have been cleaned up and resolved, leading to improved robustness in the `odp-linux` reference implementation. In addition, several memory leaks identified by the valgrind tool have been fixed. ==== Validation test resource checks The Traffic Manager validation test has certain sub-tests that require a minimum of 2 CPUs to operate properly. These tests are now skipped with a warning when run on uniprocessor systems. === Performance Performance enhancements in the `odp-linux` reference implementation have been made in packet processing, classification, and pktio, leading to increased observed throughput and packet handling rates. === Examples A new `l2fwd_simple` example has been added that does simple Layer 2 forwarding. === Documentation ==== Switch from AsciiDoc to AsciiDoctor To get better formatting capabilities and future extensibility the ODP user documentation system has been switched from http://asciidoc.org[AsciiDoc] to http://asciidoctor.org[AsciiDoctor]. There are a handful of notable changes as a result of this. Those submitting documentation patches should be aware of the following: * `monospace font` is now indicated by demarking the text with backticks (`) rather than plus signs (+). * Callouts are now indicated by C++-style double slash comments (// <1>) instead of C-style comments (/* <1> */). So, for example writing ----------------------------------------------- [source,c] ---- ...some great code deserving a callout // \<1> ---- <1> This is an example of a callout ----------------------------------------------- yields: ---- ...some great code deserving a callout // <1> ---- <1> This is an example of a callout Note that this change only affects user documentation. Code documentation still uses http://doxygen.org[Doxygen]. ==== Image Cleanup The images in the user guide have been trimmed to fit the page better. In addition, many new images have been added to better illustrate ODP API usage. ==== Additional User Documentation for Monarch APIs The *ODP User's Guide* has been updated to include new sections documenting the use of the full Monarch packet APIs as well as the Timer APIs. In addition, the crypto, classification, and traffic manager API documentation has been improved to cover all of the latest Monarch features, and an introductory section on overall ODP packet flow architecture has been added. ==== Helper Documentation The ODP Helper library now has its own document that describes these additional functions of use to ODP applications and validation tests. ==== Other documentation The Process Guide, FAQ, CONTRIBUTING, and CHANGELOG files have been reworked for the new AsciiDoctor structure, leading to a more uniform method of presenting ODP support documentation. In addition, an option for generating both a "pure" ODP API document that defines the APIs in their implementation-independent forms as well as their implementation-dependent forms for the `odp-linux` reference implementation is now available. === Known Issues ==== https://bugs.linaro.org/show_bug.cgi?id=2301[Bug 2301] The scheduler does not remove PKTIN queues following `odp_pktio_close()` ==== https://bugs.linaro.org/show_bug.cgi?id=2309[Bug 2309] The timer validation tests have seen occasional failures when run on systems containing a larger number of CPUs (typically 24 or more).

linux-dpdk: std_lib: dpdk_memcpy definition for arm/arm64 DPDK for arm/arm64 uses a #define for the rte_memcpy, which is not suitable to get as a function pointer. For those platforms, wrap it in a static function and pass its address as dpdk_memcpy.
