From 10d8cc6bf92851fcaec4a6b4c6d3554dc1eb2386 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Tue, 30 May 2017 09:30:07 -0400 Subject: Improve fifo allocator performance - add option to preallocate fifos in a segment - track active fifos with doubly linked list instead of vector - update udp redirect test code to read fifo pointers from API call instead of digging them up from fifo segment header - input-node based active-open session generator Change-Id: I804b81e99d95f8690d17e12660c6645995e28a9a Signed-off-by: Dave Barach Signed-off-by: Florin Coras Signed-off-by: Dave Barach --- src/vlibmemory/memory_shared.c | 22 ++++++++++++++++++---- 1 file changed, 18 insertions(+), 4 deletions(-) (limited to 'src/vlibmemory/memory_shared.c') diff --git a/src/vlibmemory/memory_shared.c b/src/vlibmemory/memory_shared.c index aea903304a8..41aa1231f6c 100644 --- a/src/vlibmemory/memory_shared.c +++ b/src/vlibmemory/memory_shared.c @@ -104,8 +104,17 @@ vl_msg_api_alloc_internal (int nbytes, int pool, int may_return_null) if (now - rv->gc_mark_timestamp > 10) { if (CLIB_DEBUG > 0) - clib_warning ("garbage collect pool %d ring %d index %d", - pool, i, q->head); + { + u16 *msg_idp, msg_id; + clib_warning + ("garbage collect pool %d ring %d index %d", pool, i, + q->head); + msg_idp = (u16 *) (rv->data); + msg_id = clib_net_to_host_u16 (*msg_idp); + if (msg_id < vec_len (api_main.msg_names)) + clib_warning ("msg id %d name %s", (u32) msg_id, + api_main.msg_names[msg_id]); + } shmem_hdr->garbage_collects++; goto collected; } @@ -330,6 +339,7 @@ vl_map_shmem (const char *region_name, int is_vlib) api_main_t *am = &api_main; int i; struct timespec ts, tsrem; + u32 vlib_input_queue_length; if (is_vlib == 0) svm_region_init_chroot (am->root_path); @@ -449,9 +459,13 @@ vl_map_shmem (const char *region_name, int is_vlib) shmem_hdr->version = VL_SHM_VERSION; /* vlib main input queue */ + vlib_input_queue_length = 1024; + if (am->vlib_input_queue_length) + vlib_input_queue_length = am->vlib_input_queue_length; + shmem_hdr->vl_input_queue = - unix_shared_memory_queue_init (1024, sizeof (uword), getpid (), - am->vlib_signal); + unix_shared_memory_queue_init (vlib_input_queue_length, sizeof (uword), + getpid (), am->vlib_signal); /* Set up the msg ring allocator */ #define _(sz,n) \ -- cgit 1.2.3-korg
