Subject: [dpdk-dev] [PATCH 00/12] DPDK armv8-a support
Date: Tue, 3 Nov 2015 18:39:01 +0530 [thread overview]
Message-ID: <1446556153-18845-1-git-send-email-jerin.jacob@caviumnetworks.com> (raw)
This is the v1 patchset for ARMv8 that now sits on top of the v6 patch
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 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.
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.
