Type: refactor Rb-trees are no longer maintained in the segment so we don't need to reserve memory. Keeping the option as a means to avoid underlying infra (dlmalloc) and alignment overhead. Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I84741e95d015f7b72c60d9dca20be8e0aee6a915

2020-02-25svm: refactor fifoFlorin Coras6-881/+782
Type: refactor Switch from a wrapped byte space to a "continuous" one wherein fifo chunks are appended to the fifo as more data is enqueued and chunks are removed as data is dequeued. The fifo is still subject to a maximum size, i.e., maximum number of bytes that can be enqueued, so the max number of chunks associated to the fifo is also constrained. When enqueueing data, which must fit within the available free space, if not enough "supporting" chunk memory is available, the fifo asks the fifo segment for enough chunk memory to ensure that the write can succeed. To avoid allocating large amounts of small chunks due to small writes, if possible, the size of the chunks requested is lower capped by min_alloc. When dequeuing data, all the chunks that have been completely drained, i.e., head moved beyond the chunks’ end bytes, are unlinked from the fifo and returned to the fifo segment. The one exception to this is the last chunk which is never unlinked. Change-Id: I98c1dbd9135fb79650365c7e40c29238b96cd4ee Signed-off-by: Florin Coras <fcoras@cisco.com>
2020-02-25svm: refactor fifo chunk trackingFlorin Coras3-82/+294
