2020-03-05session: reduce segment reserved bytesFlorin Coras1-3/+2
Type: refactor Rb-trees are no longer maintained in the segment so we don't need to reserve memory.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

2020-02-25session svm: tracking segment memory usageRyujiro Shibuya1-13/+141
1. segment manager would attempt to balance the usages across the segments, when it allocate fifos 2. the memory presure level is determined per fifo-segment 3. updated unit test 4. updated cli output for segments Type: feature Signed-off-by: Ryujiro Shibuya <ryujiro.shibuya@owmobility.com> Change-Id: I2923f3e0a43dd919196a0cb2cd55e098fde6cf66
2020-02-25svm: refactor fifoFlorin Coras1-94/+95
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 Coras1-23/+9
Avoid tracking with rbtrees all of the chunks associated to a fifo. Instead, only track chunks when doing out-of-order operations (peek or ooo enqueue). Type: refactor Change-Id: I9f8bd266211746637d98e6a12ffc4b2d6346950a Signed-off-by: Florin Coras <fcoras@cisco.com>
