2019-12-12session svm: per thread fifo segment slicesFlorin Coras1-12/+15
Type: refactor Change-Id: I9be652e56cdb48b0aee3253f7ce8d9bed299d824 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
2019-10-16svm: reset vector data instead of lengthBenoît Ganne1-1/+1
Reseting vector length confuses ASAN and does not reset data either. Only reset data instead. Type: fix Change-Id: Id60b8333df28a5b636a9d302b987bbad95c85c38 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2019-07-03svm: fix multi-chunk fifo alloc and add more testsFlorin Coras1-11/+148
Type: fix - make sure that chunks and the rbtree are initialized if fifo segment allocates multiple chunks for the fifo. - ensure head/tail chunks are updated on all enqueue/dequeue events, including when dropping data. - more unit tests Also fixes dequeue drop updates of head chunk.

2019-05-14svm: improve fifo segment prealloc supportFlorin Coras1-1/+114
- track fifo segment free and chunk freelist memory - improve fifo alloc. If there are enough chunks to satisfy a fifo allocation request but not enough free memory, allocate a multi-chunk fifo - add apis to preallocate chunks and fifo headers - more tests Change-Id: If18dba7ab856272c9f565d36ac36365139793e0b Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-05-07svm: decouple fifo and default chunk allocationFlorin Coras1-13/+29
Default chunk is no longer embedded into the fifo and on free is returned to its respective chunk list. Change-Id: Ifc5d214eaa6eca44356eb79dd75650fb8569113f Signed-off-by: Florin Coras <fcoras@cisco.com>

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.

2019-04-27svm: fix fifo tail/head/ooo logic for u32 wrapFlorin Coras1-12/+279
These were introduced with the switch to unbound tail/head size, so they only affect master. Added unit tests to avoid future surprises. Change-Id: I83b6c9efbe31d8092ba59b8e2ed46f4da97f35db Signed-off-by: Florin Coras <fcoras@cisco.com>
