[dpdk-dev] [PATCH v9 0/7] Expanded statistics reporting

[Remy Horton]

This patchset extends statistics reporting to include peak and
average data-rate metrics. It comes in two parts: a statistics
reporting library, and a bitrate calculation library that uses
it. This structure is intended to seperate statistic reporting
from ethdev and allow more flexible metric registration.

v9 changes:
* Updated .map files to reflect function changes in v8
* Fixed rte_malloc() of zero bytes in proc_info when no metrics exist
* Fixed rte_metrics_init not being called explicitly in testpmd

v8 changes:
* Release notes correction
* Updated copyright years
* rte_metric_init() takes socket id & must be explicitly called
* rte_metrics_reg_metric renamed to rte_metrics_reg_name()
* rte_metrics_update_metric() renamed to rte_metrics_update_value()
* Doxygen updates
* Changed malloc()/free() to rte_malloc()/rte_free()
* Removed redundant memset()
* rte_stats_bitrates_s renamed to rte_stats_bitrates_s
* Split mbuf change to own patch for visibility
* CYCLES_PER_NS now a static inline function
* latency: "hidden" pthread creation now has polling API instead.
* Struct declarations and variable definitions cleaned up
* Double initialization of the latency library now returns -EEXIST
* MAINTAINERS entry for layenctstats in correct section

v7 changes:
* RTE_METRICS_NONPORT renamed to RTE_METRICS_GLOBAL
* Multiple changes to rte_metrics.h doxygen documentation
* Split apart latency patch into lib, test-pmd, & proc_info parts
* Reordered patches by functionality
* Insufficent capacity return value changed from -ERANGE to actual size
* Cache alignment in bitrate library
* Tightened up const usage to avoid STATIC_CONST_CHAR_ARRAY warning
* Reshma reinstated as author for (now split) latency patch
* Rebase to master

v6 changes:
* Metrics display now has "Non port specific" rather than "port -1"
* Fixed sign issue in EWMA delta calculation
* Rebased to master

v5 changes:
* Updated Shared Library Versions in release notes
* Merged in Reshma's latencystats library

v4 changes:
* References to 16.11 changed to 17.02
* Fetching of non-port values was broken
* Added sanity checks to value fetching
* rte_stat_value renamed to rte_metric_value
* Corrected doxygen descriptions
* Added MAINTAINERS entries
* Added #ifdef directives to bitrate code in test-pmd

v3 changes:
* Marked rte_stats_bitrate_s as internal
* Minor integer roundoff correction
* Coding style corrections
* Removed spurious object allocation
* Changes to rte_metrics.[ch] moved from Patch 2/3 to 1/3.
* Reintroduced non-port values (RTE_METRICS_NONPORT)
* Added spinlocks to metric library
* Removed spurious test registration/update
* Added release notes entries

v2 changes:
* Uses a new metrics library rather than being part of ethdev
