2019-05-03session/svm: apis for fifo shrinkingFlorin Coras1-0/+75

2019-05-03svm: basic support for fifo shrinkingFlorin Coras1-0/+400
As opposed to growing, this is not a bulk operation, instead dependent on how the producer/consumer advance head and tail, the fifo will shrink in one or multiple steps. Only once the fifo's nitems and size are reduced to their appropriate values, equal or larger to what was requested, can the fifo chunks be collected by the owner. Chunk collection must be done with the segment heap pushed. Change-Id: Iae407ccf48d85320aa3c1e0304df56c5972c88c1 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-05-03svm: store normalized head/tail for fifoFlorin Coras1-2/+7
If head/tail are stored as "absolute" values that are normalized to [0, fifo_size] interval, when fifo is shrunk/grown the consumer and producer have to independently update to the new fifo size and fix head and tail, respectively. If the head and tail are stored as normalized values, under the right conditions, they don't need to be fixed when fifo size changes. This reverts one of the changes in gerrit 18223.

2019-04-16svm_fifo rework to avoid contention on cursizeSirshak Das1-2/+1
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>

2019-04-02vppinfra: fix sparse_vec_index() returning non-zero index for some ↵Andrew Yourtchenko2-0/+74
nonexistent elements If we are testing for an index whose membership bitmask happens to sit in LSB of uword, and there is nothing else set in that uword in the member bitmask, the shortcut path returning the valid index is taken even if the element with a given index doesn't exist in the sparse vector. This happens because the count of leading zeroes on the value of 0 is zero, which is equal to the value taken modulo bitsize uword. Take care of that case. Also add unittests showing the problem and verifying that sparse_vec_index2 does not have the same issue.
