Sometimes apps (or perhaps DPDK driver components) may want to allow use of "external" i.e. non EAL allocated, memory as though it were standard DPDK memory. This patchset provides the ability to do this, by: firstly, adding an explicit flag to indicate non-EAL memory, rather than relying on the socket_id implicitly, and then secondly, allowing heaps to be swapped, so an external heap can be used as the default heap for socket 0 or 1, etc.
V3: * Expand to 2 patch set, adding patch to tag external memory explicitly, before adding the swap function * Add locks to improve thread safety of the swap opperation. * Add additional notes to function to clarify usage. V2: * Fix doxygen comment issue on doc builds Bruce Richardson (2): eal: add flag to indicate non-EAL malloc heaps eal: allow swapping of malloc heaps lib/eal/common/malloc_heap.c | 46 ++++++++++++++++++++++++++++-------- lib/eal/common/malloc_heap.h | 1 + lib/eal/common/malloc_mp.c | 5 ++-- lib/eal/common/rte_malloc.c | 14 ++++++----- lib/eal/include/rte_malloc.h | 34 ++++++++++++++++++++++++++ lib/eal/version.map | 2 ++ 6 files changed, 83 insertions(+), 19 deletions(-) -- 2.39.2
