6 years agonet: implement CRC for ARM64 NEON
Ashwin Sekhar T K [Tue, 4 Jul 2017 09:24:07 +0000 (02:24 -0700)]
net: implement CRC for ARM64 NEON

Added CRC compute APIs for arm64 utilizing the pmull
capability.

Added new file net_crc_neon.h to hold the arm64 pmull
CRC implementation.

Added wrappers in rte_vect.h for those neon intrinsics
which are not supported in GCC version < 7.

Verified the changes with crc_autotest unit test case

6 years agomem: balanced allocation of hugepages
Ilya Maximets [Thu, 29 Jun 2017 05:59:19 +0000 (08:59 +0300)]
mem: balanced allocation of hugepages

Currently EAL allocates hugepages one by one not paying attention
from which NUMA node allocation was done.

Such behaviour leads to allocation failure if number of available
hugepages for application limited by cgroups or hugetlbfs and
memory requested not only from the first socket.

Example:
# 90 x 1GB hugepages availavle in a system

cgcreate -g hugetlb:/test
# Limit to 32GB of hugepages
cgset -r hugetlb.1GB.limit_in_bytes=34359738368 test
# Request 4GB from each of 2 sockets
cgexec -g hugetlb:test testpmd --socket-mem=4096,4096 ...

EAL: SIGBUS: Cannot mmap more hugepages of size 1024 MB
EAL: 32 not 90 hugepages of size 1024 MB allocated
EAL: Not enough memory available on socket 1!
     Requested: 4096MB, available: 0MB
PANIC in rte_eal_init():
Cannot init memory

This happens beacause all allocated pages are
on socket 0.

Fix this issue by setting mempolicy MPOL_PREFERRED for each hugepage
to one of requested nodes using following schema:

1) Allocate essential hugepages:
1.1) Allocate as many hugepages from numa N to
     only fit requested memory for this numa.
1.2) repeat 1.1 for all numa nodes.
2) Try to map all remaining free hugepages in a round-robin
   fashion.
3) Sort pages and choose the most suitable.

In this case all essential memory will be allocated and all remaining
pages will be fairly distributed between all requested nodes.

New config option RTE_EAL_NUMA_AWARE_HUGEPAGES introduced and
enabled by default for linuxapp except armv7 and dpaa2.
Enabling of this option adds libnuma as a dependency for EAL.
