mk: change dpaa2 machine flag to cortex-a72 DPAA2 devices now support cortex-a72. They no longer support a57. Also fp and simd is no more required to be stated explicitly for standard a72 core. Signed-off-by: Hemant Agrawal <hemant.agrawal@nxp.com>

config: set cache line as 128B for generic arm64 armv8 implementations may have 64B or 128B cache line. Setting to the maximum available cache line size in generic config to address minimum DMA alignment across all arm64 implementations. Increasing the cacheline size has no negative impact to cache invalidation on systems with a smaller cache line. The need for the minimum DMA alignment has impact on functional aspects of the platform so default config should cater the functional aspects. There is an impact on memory usage with this scheme, but that's not too important for the single image arm64 distribution use case. The arm64 linux kernel followed the similar approach for single arm64 image use case. http://lxr.free-electrons.com/source/arch/arm64/include/asm/cache.h Signed-off-by: Jerin Jacob <jerin.jacob@caviumnetworks.com> Acked-by: Jianbo Liu <jianbo.liu@linaro.org> Acked-by: Santosh Shukla <santosh.shukla@caviumnetworks.com>

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.
