This patchset provides the ability to do this,\nby: firstly, adding an explicit flag to indicate non-EAL memory,\nrather than relying on the socket_id implicitly, and then secondly,\nallowing heaps to be swapped, so an external heap can be used as the\ndefault heap for socket 0 or 1, etc.\n\nV3:\n* Expand to 2 patch set, adding patch to tag external memory\n explicitly, before adding the swap function\n* Add locks to improve thread safety of the swap opperation.\n* Add additional notes to function to clarify usage.\n\nV2:\n* Fix doxygen comment issue on doc builds\n\nBruce Richardson (2):\n eal: add flag to indicate non-EAL malloc heaps\n eal: allow swapping of malloc heaps\n\n lib/eal/common/malloc_heap.c | 46 ++++++++++++++++++++++++++++--------\n lib/eal/common/malloc_heap.h | 1 +\n lib/eal/common/malloc_mp.c | 5 ++--\n lib/eal/common/rte_malloc.c | 14 ++++++-----\n lib/eal/include/rte_malloc.h | 34 ++++++++++++++++++++++++++\n lib/eal/version.map | 2 ++\n 6 files changed, 83 insertions(+), 19 deletions(-)\n\n--\n2.39.2" }
