2019-04-16svm_fifo rework to avoid contention on cursizeSirshak Das5-25/+18
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>
2019-04-16QUIC: Initial multi stream supportAloys Augustin1-0/+1
To connect a stream, apps should call connect while passing the id of the QUIC connection in the new transport_opts field in session_endpoint_cfg_t. Apps are notified of new streams with their accept callback, which is called each time a peer opens a stream.

current session rule cli can not add session rule of proto is udp. because vnet_session_rule_add_del function's paramter does not include transport_proto element in args struct, but session rule type on the basis of input args's transport_proto when create session rule with vnet_session_rule_add_del function, so just add transport_proto element to vnet_session_rule_add_del function's args that to solve this problem Change-Id: If1a5942b4a0b006d73376e0cb01b97e84c593493 Signed-off-by: zhanglimao <zhanglimao0017@gmail.com>
