2019-05-20consolidate all mutux opertionPing Yu1-17/+17
replace all pthread_mutex_lock/unlock to be svm_queue_lock/unlock So there all operation is based on defined mutux, and it can help us to debug or replace mutux locking method Change-Id: I9aeeb03bbbbf3d7a824c06a535e5d6a6b463b42c Signed-off-by: Ping Yu <ping.yu@intel.com>

2018-08-10vcl: support for eventfd mq signalingFlorin Coras1-18/+67
- support eventfd based mq signaling. Based on configuration, vcl epoll/select can use either condvars or epoll on mq eventfds. - add vcl support for memfd segments - vpp explicitly registers cut-through segments with apps/vcl - if using eventfd, make ldp allow one call to libc_epoll_create. Needed for the message queue epfd - update svm_queue_t to allow blocking calls with eventfd signaling.

2018-01-22svm: queue sub: Add conditional timed waitMohsin Kazmi1-5/+26
On reviece side svm queue only permits blocking and non-blocking calls. This patch adds timed wait blocking functionality which returns either on signal/event or on given time out. It also preserves the original behavior, so it will not hurt client applications which are using svm queue.

2018-01-09api: refactor vlibmemoryFlorin Coras1-0/+410
- separate client/server code for both memory and socket apis - separate memory api code from generic vlib api code - move unix_shared_memory_fifo to svm and rename to svm_fifo_t - overall declutter Change-Id: I90cdd98ff74d0787d58825b914b0f1eafcfa4dc2 Signed-off-by: Florin Coras <fcoras@cisco.com>
