2020-01-27libmemif: memif_control_fd_update always pass context from libmemif_mainJakub Grajciar1-0/+5
Event polling instance is always identified by libmemif main private context. Fixes event polling handled by libmemif. Type: fix Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: I51dcdb279b18f8ce97bad3b2695848e0b25a232d
2019-08-21libmemif: introduce 'memif_per_thread_' namespaceJakub Grajciar1-4/+132
APIs in 'memif_per_thread_' namespace are used to split the global database into separate databases, to improve multi-thread use cases. Using 'memif_per_thread_init' client can create separate libmemif databases (libmemif_main_t). Client will reference these databases using memif_per_thread_handle_t. Each database requires unique socket. Created interface will be stored in the same database as the socket passed in connection arguments. Example code: extras/libmemif/examples/icmp_responder_3-1/main.c Type: feature Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com> Change-Id: I261563ecc34761a76e94f20c20015394398ddfd7 Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com>
2019-07-02libmemif: version 3.0Jakub Grajciar1-7/+41
Add support for multi-thread connection establishment. - control_fd_update() callback now passes private context associated with updated file descriptor. File descriptor can belong to memif socket, memif connection or timerfd. In case of timerfd the context is NULL. - memif_create_socket() new API. Creates memif socket handle to be passed to memif_create() in memif_conn_args_t. This API allows to pass private context whenever the file descriptor is updated. - memif_delete_socket() new API. Deletes memif socket. Socket must not be in use by any interface. Type: feature Change-Id: I7ca4e4349595d4477195f1c32403d3e3a6eb5361 Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com>

2018-03-30libmemif: zero-copy-slave mode + header spaceJakub Grajciar1-2/+24
Slave is now able to dequeue buffers from rx queue and enqueue them to tx queue (zero-copy operation). Slave can produce buffers with headroom, which will allow adding encap without copy. Change-Id: Ia189f8de1a68be787545ed46cf78d36403e7e9bf Signed-off-by: Jakub Grajciar <jgrajcia@cisco.com>
