2019-11-18session tcp: infra for transports to send buffersFlorin Coras1-0/+14
Type: feature Add infra that allows transpors to enqueue pending buffers without the need to build and manage their own pending frames. An important benefit is the fact that buffer wire/tx ordering is ensured by session layer.

2019-09-30session: move ctrl messages from bapi to mqFlorin Coras1-53/+319
Type:refactor Moves connect, disconnect, bind, unbind and app detach to message queue from binary api. Simplifies app/vcl interaction with the session layer since all session control messages are now handled over the mq. Add/del segment messages require internal C api changes which affect all builtin applications. They'll be moved in a different patch and might not be back portable to 19.08. Change-Id: I93f6d18e551b024effa75d47f5ff25f23ba8aff5 Signed-off-by: Florin Coras <fcoras@cisco.com> (cherry picked from commit 458089bbad9cf5bef6cf8119f23fc44e66b36ad3)
2019-09-20session: add explicit reset apiFlorin Coras1-0/+6
Type: feature This can be used to forcefully close a session. It's only available to builtin applications for now. Transports must support the reset api otherwise normal close is used.

2019-08-09session: allow closed transports to sendFlorin Coras1-4/+16
Type:fix Transports like tcp may notify session layer of a close but they may defer the connection's deletion (e.g., tcp time-wait). During that time, transports may still want to send packets. So, unless the session has no transport (transport-deleted state), allow the transport to send.

2019-07-29session: fix vpp to app msg generationFlorin Coras1-6/+3
Type:fix Freeing mq messages in vpp (producer), if enqueueing fails, invalidates consumer assumption that messages can be freed without a lock. Change-Id: I748a33b8846597bdad865945d8e899346d482434 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Tal Saiag <tal.saiag@gmail.com>

2019-04-16svm_fifo rework to avoid contention on cursizeSirshak Das1-4/+6
Problems Addressed: - Contention of cursize by producer and consumer. - Reduce the no of modulo operations. Changes: - Synchronization between producer and consumer changed from cursize to head and tail indexes Implications: reduces the usable size of fifo by 1. - Using weaker memory ordering C++11 atomics to access head and tail based on producer and consumer role. - Head and tail indexes are unsigned 32 bit integers. Additions and subtraction on them are implicit 32 bit Modulo operation. - Adding weaker memory ordering variants of max_enq, max_deq, is_empty and is_full Using them appropriately in all places. Perfomance improvement (iperf3 via Hoststack): iperf3 Server: Marvell ThunderX2(AArch64) - iperf3 Client: Skylake(x86) ~6%(256 rxd/txd) - ~11%(2048 rxd/txd) Change-Id: I1d484e000e437430fdd5a819657d1c6b62443018 Signed-off-by: Sirshak Das <sirshak.das@arm.com> Reviewed-by: Honnappa Nagarahalli <honnappa.nagarahalli@arm.com>
