2019-05-03svm: basic support for fifo shrinkingFlorin Coras2-78/+263
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 Coras2-51/+41
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.
