Subject: [dpdk-dev] [PATCH v3 00/14] DPDK armv8-a support
Date: Fri, 6 Nov 2015 15:10:19 +0530 [thread overview]
Message-ID: <1446802833-22265-1-git-send-email-jerin.jacob@caviumnetworks.com> (raw)
This is the v3 patchset for ARMv8 that now sits on top of the v6 patch
(based on upstream 82fb702077f67585d64a07de0080e5cb6a924a72)
of the ARMv7 code by RehiveTech. It adds code into the same arm include
directory, reducing code duplication.
Tested on an ThunderX arm 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 as long as there is no unaligned access to
device memory but not yet untested.
Compiles igb_uio, kni and all the physical device PMDs.
An entry has been added to the Release notes.
v1..v2
1) included "Introduce rte_smp_*mb() for memory barriers to use between lcores"
patch ACK by Konstantin in v2 as
"eal: introduce rte_smp_*mb() for memory barriers to use between lcores"
please superseded the original one
2) defined rte_smp_mb(), rte_smp_wmb(), rte_smp_rmb() for arm
(1) and (2) fixes "Mbuf autotest" stress failure found in version 1
3) fixed white space issues with patch 8,9,10
4) disabled CONFIG_RTE_LIBRTE_FM10K_PMD, CONFIG_RTE_LIBRTE_I40E_PMD
due to tmmintrin.h depenency or ARM
v2..v3
1) moved disabled CONFIG_RTE_LIBRTE_FM10K_PMD, CONFIG_RTE_LIBRTE_I40E_PMD
to "mk: add support for armv8 on top of armv7" and
"mk: add support for thunderx machine target based on armv8-a"
to fix compilation issue per patch
NOTE:
Part of the work has been taken from David Hunt's v3 patch who was
initiated the armv8 port.
Notes on arm64 kernel configuration:
Tested on using Ubuntu 14.04 LTS with a 3.18 kernel and igb_uio.
ARM64 kernels does not have functional resource mapping of PCI memory
(PCI_MMAP), so the pci driver needs to be patched to enable this. The
symptom of this is when /sys/bus/pci/devices/0000:0X:00.Y directory is
missing the resource0...N files for mmapping the device memory.
Following patch fixes the PCI resource mapping issue om armv8.
Its not yet up streamed.We are in the process of up streaming it.
