Subject: [dpdk-dev] [PATCH v2 0/2] ring: allow to init a rte_ring outside of an rte_memzone
These 2 patches adds 2 new functions that permits to initialize and use
a rte_ring anywhere in memory.
Before this patches, only rte_ring_create() was available. This function
allocates a rte_memzone (that cannot be freed) and initializes a ring
inside.
This series allows to do the following:
size = rte_ring_get_memsize(1024);
r = malloc(size);
rte_ring_init(r, "my_ring", 1024, 0);
Changes included in v2:
- fix syntax for functions definitions in rte_ring_get_memsize()
- use RTE_ALIGN() to get nearest higher multiple of cache line size
- fix description of rte_ring_init() in doxygen comments
Olivier Matz (2):
ring: introduce rte_ring_get_memsize()
ring: introduce rte_ring_init()
