CSIT

https://wiki.fd.io/view/CSIT/AArch64

AArch64 Tuning

Areas:

  • Profiling analysis & optimization
  • Runtime selection of code using existing methods in VPP

AArch64 Porting

Areas:

  • Hardware topology variation, e.g. non PCIe NICs
  • VPP-1215 - TC01 : Process untagged send tagged testcase failing due to same packet received as sent

All: JIRA issues with ARM64 label

Assigned and New:

CSIT-1019 In some situations the receive timeout of PacketVerifier.RxQueue is not working Khem
CSIT-1021 Jumbo frames tests based on Scapy pcap receive functions limited to 1600 bytes Khem
CSIT-1023 Look to extend crypto VPP func tests to support OpenSSL based PMD in DPDK Adarsh
CSIT-1043 Guest OS becomes unresponsive during CSIT crypto suite execution Khem
CSIT-990 CSIT uses buildroot package for nested VM image which doesn't support AARCH64 Nitin
VPP-1174 Prefetch hotspots Brian
VPP-1126 Benchmark and optimize clib_memcpy64_x4() Khem
VPP-1103 Use correct CPU freq on ARM platforms Sirshak
VPP-1114 Ensure correctness of atomics and memory ordering Sirshak
VPP-1267 L3Fwd performance tuning on Macchiatobin
VPP 1268 Support for configuring memory channels in DPDK-INPUT
Add top level make argument for custom cache line size VPP-1064 Nitin Saxena

Known Issues

Compilation may fail on systems with less than 1GB memory per core. One workaround is to search for -j in build-root/Makefile and multiply by 1 instead of 2.

GCC 5.3.x ICEs during FP register allocation. Please use GCC 5.4+.

Try disabling ASLR if experiencing random crashes: sysctl -w kernel.randomize_va_space=0
