2019-05-14Preallocate mhash key_tmps vectorDave Barach1-1/+2
Fix os_get_nthreads() so that it starts returning the correct answer as early as possible. Change-Id: Id5292262f2c3f521b07ffbe6a9f6748dcc4dcb7d Signed-off-by: Dave Barach <dave@barachs.net>
2019-05-06gcov / test framework: sigterm not sigkillDave Barach1-0/+11
Otherwise, gcov data vanishes without a trace. Add a __gcov_flush() call to the unix signal handler, under #ifdef CLIB_GCOV. Add -DCLIB_GCOV to vpp_gcov_TAG_CFLAGS. Change-Id: I2726e671b26dfbe7fae88f46a8207bb2b5106884 Signed-off-by: Dave Barach <dave@barachs.net>

2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-0/+2
Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc. Main advantage: dlmalloc mspaces have no inherent size limit. Change-Id: I19b3f43f3c65bcfb82c1a265a97922d01912446e Signed-off-by: Dave Barach <dave@barachs.net>
2018-06-26add backtrace in unix_signal_handlerKingwel Xie1-9/+49
crash stack backtrace will be directed to syslog 1. make use of glic backtrace in execinfo.h. the old clib_backtrace is removed 2. install SIGABRT in signal handler, but have to remove it when backtrace is done. reason is to capture stack trace caused by SIGABRT. vPP ASSERT always call os_exit then abort(). we definitely want to know the trace of this situation. It is a little tricky to avoid SIGABRT infinite loop 3. always load symbols by calling clib_elf_main_init () in main(). Otherwise, PC addresses instead of symbols will be displayed.

2018-06-21configurable per-dispatch-cycle sleepDave Barach1-0/+2
Workaround for lack of driver interrupt support. Also quite handy for home gateway, laptop/vagrant, other use-cases not requiring maximum vectors/second for proper operation. Change-Id: Ifc4b98112450664beef67b89ab8a6940a3bf24b5 Signed-off-by: Dave Barach <dave@barachs.net>
2018-03-05physmem: keep only one physmem_mainDamjan Marion1-0/+1
We don't need per vlib_main physmem_main, so keep it separatelly instead of trying to keep them in sync. Change-Id: I0fbeecf4d9672d31af7a43c640a7d8f05dd6e46f Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-10-14VPP-1029: Don't call clib_longjmp(...) directly from the SIGTERM handlerDave Barach1-4/+3
It's way too easy to imagine leaving a mutex or a spin-lock held in the /vpe-api shared-memory segment, or elsewhere. Set a volatile variable and check it in a safe place... Change-Id: I9d91c38cffeb921143c272162d055c9c24a6c312 Signed-off-by: Dave Barach <dave@barachs.net>

2017-04-06Use thread local storage for thread indexDamjan Marion1-24/+19
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-02-03Plugin infrastructure improvementsDamjan Marion1-0/+8
This patch replaces requirement for vlib_plugin_register function in the plugin so file and introduces new macro: VLIB_PLUGIN_REGISTER () = { .version = "version string", .version_required = "requred version", .default_disabled = 1, .early_init = "early_init_function_name", }; Plugin will nor be loaded if .default_disabled is set to 1 unless explicitely enabled in startup.conf. If .verstion_required is set, plugin will not be loaded if there is version mismatch between plugin and vpp. This can be bypassed by setting "skip-version-check" for specific plugin. If .early-init string is present, plugin loader will try to resolve this specific symbol in the plugin namespace and make a function call. Following startup.conf configuration is added: plugins { path /path/to/plugin/directory plugin ila_plugin.so { enable skip-version-check } plugin acl_plugin.so { disable } } Change-Id: I706c691dd34d94ffe9e02b59831af8859a95f061 Signed-off-by: Damjan Marion <damarion@cisco.com>
