Hi DPDK Community.
This is an updated patchset for ARMv8 that now sits on top of the previously
submitted ARMv7 code by RehiveTech. It re-uses a lot of that code, and splits
some header files into 32-bit and 64-bit versions, so uses the same arm include
directory.
Tested on an XGene 64-bit arm server board, with PCI slots. Passes traffic between
two physical ports on an Intel 82599 dual-port 10Gig NIC. Should work with many
other NICS, but these are as yet untested.
Compiles igb_uio, kni and all the physical device PMDs.
ACL and LPM are disabled due to compilation issues.
Note added to the Release notes.
David Hunt (5):
eal/arm: split arm rte_memcpy.h into 32 and 64 bit versions.
eal/arm: split arm rte_prefetch.h into 32 and 64 bit versions
eal/arm: fix 64-bit compilation for armv8
mk: Add makefile support for armv8 architecture
test: add test for cpu flags on armv8
