The objective of this patchset is to introduce a framework to support dynamic log types in EAL. It also provides one example of use (in i40e).
Features: - log types are identified by a string - at registration, a uniq identifier is associated to a log type - each log type can have its level changed dynamically - extend command line parameters to set the log level of a specific type, or logs matching a regular expression - keep compat with other legacy types (eal, malloc, ring, user*, etc... keep their hardcoded log type value) Next step is to adapt drivers, libs and apps to use this new API. At the end, we can expect that all non-dataplane logs are moved to be dynamic, so we can enable/disable them at runtime, without recompiling. Many debug options can probably be removed from configuration: $ git grep DEBUG config/common_base | wc -l 89 RFC -> v1: - rebase on top of current master - fix eal help alignment - remove unused i40e compilation options Olivier Matz (8): eal: support dynamic log types eal: dump registered log types eal: change several log levels matching a regexp eal: change specific log levels at startup eal: deprecate log functions app/test: new command to dump log types app/testpmd: new command to dump log types net/i40e: use dynamic log type for control logs app/test-pmd/cmdline.c | 5 +- config/common_base | 2 - doc/guides/contributing/coding_style.rst | 30 ++-- drivers/net/i40e/i40e_ethdev.c | 18 +- drivers/net/i40e/i40e_fdir.c | 4 - drivers/net/i40e/i40e_logs.h | 17 +- examples/quota_watermark/qw/main.c | 2 +- examples/quota_watermark/qwctl/qwctl.c | 2 +- lib/librte_eal/bsdapp/eal/eal.c | 4 +- lib/librte_eal/bsdapp/eal/rte_eal_version.map | 6 + lib/librte_eal/common/eal_common_log.c | 219 +++++++++++++++++++++++- lib/librte_eal/common/eal_common_options.c | 49 ++++-- lib/librte_eal/common/include/rte_log.h | 76 +++++++- lib/librte_eal/linuxapp/eal/eal.c | 4 +- lib/librte_eal/linuxapp/eal/rte_eal_version.map | 6 + test/test/commands.c | 4 +- test/test/test_logs.c | 12 +- 17 files changed, 395 insertions(+), 65 deletions(-) -- 2.8.1
