The first is support for idled (sleeping and frequency-stepped) CPU cores, and the second is support for applications to be notified of active as well as faulted cores. The latter is to allow core state to be relayed to external (secondary) processes, which is demonstrated by changes to the l2fed-keepalive example. -- v3 changes * Rebased to master * Changed keepalive state enumerations to use RTE_ prefix * Added missing parameter documentation * Doc changes squashed v2 changes: * Some date & typos fixups * State enum made public and extended with new states * Generalised 'alive' callback to all states * Last-alive shows gone-to-sleep time for idle cores * Removed some redundant sanity checks * Last-alive time exposed to application * #define'd semaphore timeout * Agent checks for dead keepalive Remy Horton (3): eal: export keepalive state enumerations eal: add additional keepalive callbacks examples/l2fwd-keepalive: add IPC liveness reporting doc/guides/rel_notes/release_16_07.rst | 6 + examples/Makefile | 3 +- examples/l2fwd-keepalive/Makefile | 4 +- examples/l2fwd-keepalive/ka-agent/Makefile | 48 ++++++++ examples/l2fwd-keepalive/ka-agent/main.c | 150 ++++++++++++++++++++++++ examples/l2fwd-keepalive/main.c | 22 +++- examples/l2fwd-keepalive/shm.c | 128 ++++++++++++++++++++ examples/l2fwd-keepalive/shm.h | 89 ++++++++++++++ lib/librte_eal/bsdapp/eal/rte_eal_version.map | 1 + lib/librte_eal/common/include/rte_keepalive.h | 63 +++++++++- lib/librte_eal/common/rte_keepalive.c | 64 +++++++--- lib/librte_eal/linuxapp/eal/rte_eal_version.map | 1 + 12 files changed, 558 insertions(+), 21 deletions(-) create mode 100644 examples/l2fwd-keepalive/ka-agent/Makefile create mode 100644 examples/l2fwd-keepalive/ka-agent/main.c create mode 100644 examples/l2fwd-keepalive/shm.c create mode 100644 examples/l2fwd-keepalive/shm.h -- 2.5.5
