We encounter following issues while trying to build VPP over ARM 64. It seems
right now only ARM32 are supported in the code. I list the steps we tried and
hope VPP folks can help us work around this issue.
Steps:
1. install Ubuntu 16.04 on OD1K
$>> uname -a
Linux OD1K 4.4.0-92-generic #115-Ubuntu SMP Thu Aug 10 09:10:33 UTC 2017
aarch64 aarch64 aarch64 GNU/Linux
2. git clone VPP 17.04 and build VPP
## Error:
make[2]: Entering directory '/home/huawei/GIT/vpp.1704/dpdk'
cat: '/sys/bus/pci/devices/0000:00:01.0/uevent': No such file or directory
**Work around to bypass MakeFile:
##############################################################################
# Cavium ThunderX
##############################################################################
#else ifneq (,$(findstring thunder,$(shell cat
/sys/bus/pci/devices/0000:00:01.0/uevent | grep cavium)))
else
export CROSS=""
DPDK_TARGET ?= arm64-thunderx-linuxapp-$(DPDK_CC)
DPDK_MACHINE ?= thunderx
DPDK_TUNE ?= generic
3. Then, make build and failed following:
/home/huawei/GIT/vpp.1704/build-data/../src/plugins/dpdk/device/node.c:276:9:
error: `u8x32' undeclared (first use in this function)
*(u8x32 *) (((u8 *) d0) + i * 32) =
** Check vppinfra/vppinfra/vector.h and don't find u8x32 with "aarch64"
#if defined (__aarch64__) || defined (__arm__)
typedef unsigned int u32x4 _vector_size (16);
typedef u8 u8x16 _vector_size (16);
typedef u16 u16x8 _vector_size (16);
typedef u32 u32x4 _vector_size (16);
typedef u64 u64x2 _vector_size (16);
#endif
4. According https://wiki.fd.io/view/VPP/Alternative_builds
The VPP seems to support arm32 only .
export PLATFORM=arm32
*Questions:
Did I miss some steps or should include other header files that defines u8x32?
Thanks,
George
