As part of these tests a dummy service is registered which allows identifying if a service callback has been invoked by using the CPU tick counter. This allows identifying if functions to start and stop service lcores are actually having effect. Signed-off-by: Harry van Haaren Acked-by: Jerin Jacob --- v5: - Improve unit test for dump() to enable and disable stats (Jerin) - Add new unit test for MT unsafe service callback (Harry) - Added Ack from ML v4: - Remove static slcore_id, make service-core choice dynamic (Jerin) - Use lcore_get_next() to acquire service cores (Jerin) - Improve unit test to ensure app can remote_launc() on a core that previously served as a service-core (verifies ROLE_RTE is set) (Jerin) v2 changes; - Rename variable to slcore_id (Jerin) - Rename function to unregister_all() (Jerin) - Fix typos (Jerin) - Add unit test for get_by_name() - Add unit tests (all suggestions by Jerin) -- get_name() -- Verify probe_capability API -- Verify MT_SAFE capability (see code for details) -- Verify rte_service_dump() API --- test/test/Makefile | 2 + test/test/test_service_cores.c | 599 +++++++++++++++++++++++++++++++++++++++++ 2 files changed, 601 insertions(+) create mode 100644 test/test/test_service_cores.c diff --git a/test/test/Makefile b/test/test/Makefile index e797c20..42d9a49 100644 --- a/test/test/Makefile +++ b/test/test/Makefile @@ -151,6 +151,8 @@ SRCS-y += test_interrupts.c SRCS-y += test_version.c SRCS-y += test_func_reentrancy.c +SRCS-y += test_service_cores.c + SRCS-$(CONFIG_RTE_LIBRTE_CMDLINE) += test_cmdline.c SRCS-$(CONFIG_RTE_LIBRTE_CMDLINE) += test_cmdline_num.c SRCS-$(CONFIG_RTE_LIBRTE_CMDLINE) += test_cmdline_etheraddr.c diff --git a/test/test/test_service_cores.c b/test/test/test_service_cores.c new file mode 100644 index 0000000..88fac8f --- /dev/null +++ b/test/test/test_service_cores.c @@ -0,0 +1,599 @@ +/*- + * BSD LICENSE + * + * Copyright(c) 2017 Intel Corporation.
