2024-09-12vlib: introduce lazy next node initializationMohammed Hawari1-0/+4
This change allow a node registration A to name a next node B that does not exist yet at registration time. When node B is effectively created, vlib_node_main_lazy_next_update need to be called so that the vlib graph is updated accordingly. To enable this behavior, node A needs to bear the new VLIB_NODE_FLAG_ALLOW_LAZY_NEXT_NODES.

2022-03-30vppinfra: vector allocator reworkDamjan Marion1-5/+3
- support of in-place growth of vectors (if there is available space next to existing alloc) - drops the need for alloc_aligned_at_offset from memory allocator, which allows easier swap to different memory allocator and reduces malloc overhead - rework of pool and vec macros to inline functions to improve debuggability - fix alignment - in many cases macros were not using native alignment of the particular datatype. Explicitly setting alignment with XXX_aligned() versions of the macro is not needed anymore in > 99% of cases - fix ASAN usage - avoid use of vector of voids, this was root cause of several bugs found in vec_* and pool_* function where sizeof() was used on voids instead of real vector data type - introduce minimal alignment which is currently 8 bytes, vectors will be always aligned at least to that value (underlay allocator actually always provide 16-byte aligned allocs) Type: improvement Change-Id: I20f4b081bb13bbf7bc0ace85cc4e301787f12fdf Signed-off-by: Damjan Marion <damarion@cisco.com>

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-32/+2
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

2019-05-29Break out the broom for some cleanup workDave Barach1-0/+10
Maintain the MAINTAINERS file. Removed src/plugins/*.am listings. Added a couple of plugins. Add vlib_process_create (vlib_main_t *vm, char *name, vlib_node_function_t *f, u32 log2_n_stack_bytes); /** @brief Create a vlib process * @param vm &vlib_global_main * @param f the process node function * @param log2_n_stack_bytes size of the process stack, defaults to 16K * @return newly-create node index * @warning call only on the main thread. Barrier sync required. */ This function makes it easy to spin up periodic processes when features are enabled for the first time. That coding pattern is highly recommended. Update the emacs-lisp plugin generator to use vlib_process_create, instead of generating static periodic process nodes.
