Bug ID: 378
Summary: takes more than 500ms to allocate memory from a
certain heap
Product: DPDK
Version: 18.11
Hardware: ARM
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: chuqif...@hisilicon.com
Target Milestone: ---
file: lib/librte_eal/common/malloc_heap.c
function: malloc_heap_alloc_on_heap_id
code snippet:
if (!alloc_more_mem_on_socket(heap, size, socket_id, flags, align,
bound, contig)) {
ret = heap_alloc(heap, type, size, flags, align, bound,
contig);
/* this should have succeeded */
if (ret == NULL)
RTE_LOG(ERR, EAL, "Error allocating from heap\n");
}
alloc_more_mem_on_socket takes more than 500ms when numa node0 runs out of
memory.
our program has 64 threads which all can get memory from dpdk(hugepagesz=1G).
our business code can not go well with such code snippet, so we remove
alloc_more_mem_on_socket in malloc_heap_alloc_on_heap_id, we test it more than
1 month, and it runs ok
so, is there any side effect when i remove alloc_more_mem_on_socket in
malloc_heap_alloc_on_heap_id?
