Known Issues:

  • These DPDK applications may fail depending on hardware/memory configuration: kni_autotest, power_kvm_vm_autotest, power_acpi_cpufreq_autotest, power_autotest, eal_flags_autotest, lpm6_autotest, memcpy_perf_autotest, table_autotest, pmd_perf_autotest.
  • The dynamic compression is disabled for this QAT package version.
  • To restart the QAT service use argument ‘shutdown’ and then ‘start’, use of ‘restart’ and ‘stop’-‘start’ argument may cause failure of service.
