2019-05-14svm: improve fifo segment prealloc supportFlorin Coras1-2/+2
- 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>

2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-14/+45
Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc. Main advantage: dlmalloc mspaces have no inherent size limit. Change-Id: I19b3f43f3c65bcfb82c1a265a97922d01912446e Signed-off-by: Dave Barach <dave@barachs.net>

2018-02-14session: support local sessions and deprecate redirectsFlorin Coras1-3/+6
Memfd backed shared memory segments can only be negotiated over sockets. For such scenarios, the existing redirect mechanism that establishes cut-through sessions does not work anymore as the two peer application do not share such a socket. This patch adds support for local sessions, as opposed to sessions backed by a transport connection, in a way that is almost transparent to the two applications by reusing the existing binary api messages. Moreover, all segment allocations are now entirely done through the segment manager valloc, so segment overlaps due to independent allocations previously required for redirects are completely avoided. The one notable characteristic of local sessions (cut-through from app perspective) notification messages is that they carry pointers to two event queues, one for each app peer, instead of one. For transport-backed sessions one of the queues can be inferred but for local session they cannot. Change-Id: Ia443fb63e2d9d8e43490275062a708f039038175 Signed-off-by: Florin Coras <fcoras@cisco.com>
