2024-02-23svm: Use ftruncate to expand svm on FreeBSDTom Jones1-1/+10
Linux doesn't support the Linux idiom of using lseek and a write to set the size of a file, instead use ftruncate to accomplish the same effect. This change is taken from the Nanoteq VPP port commit: https://github.com/ftk-ntq/vpp/commit/04a1b19b37e791accc61b91f3f413d8bc8b1ff8f Type: improvement Change-Id: Ie0b83e751b8b8f20b6814e5c9f760035747dfad9 Signed-off-by: Tom Jones <thj@freebsd.org>

2023-08-09session: async rx event notificationsFlorin Coras2-5/+16
Move from synchronous flushing of io and ctrl events from transports to applications to an async model via a new session_input input node that runs in interrupt mode. Events are coalesced per application worker. On the one hand, this helps by minimizing message queue locking churn. And on the other, it opens the possibility for further optimizations of event message generation, obviates need for rx rescheduling rpcs and is a first step towards a fully async data/io rx path.

2022-03-30vppinfra: vector allocator reworkDamjan Marion1-17/+0
- support of in-place growth of vectors (if there is available space next to existing alloc) - drops the need for alloc_aligned_at_offset from memory allocator, which allows easier swap to different memory allocator and reduces malloc overhead - rework of pool and vec macros to inline functions to improve debuggability - fix alignment - in many cases macros were not using native alignment of the particular datatype. Explicitly setting alignment with XXX_aligned() versions of the macro is not needed anymore in > 99% of cases - fix ASAN usage - avoid use of vector of voids, this was root cause of several bugs found in vec_* and pool_* function where sizeof() was used on voids instead of real vector data type - introduce minimal alignment which is currently 8 bytes, vectors will be always aligned at least to that value (underlay allocator actually always provide 16-byte aligned allocs) Type: improvement Change-Id: I20f4b081bb13bbf7bc0ace85cc4e301787f12fdf Signed-off-by: Damjan Marion <damarion@cisco.com>

2021-03-29svm session vcl: per app rx message queuesFlorin Coras1-1/+1
Add option to use per app private segments for app to vpp message queues, as opposed to exposing internal message queues segment. When so configured, internal message queues are still polled by the session queue node but external app message queues are handled by a new input node (appsl-rx-mqs-input) that runs in interrupt state. Signaling of the node, when mqs receive new messages, is done through eventfds epolled by worker epoll input nodes.
