# Reasons for not being an dh_autotest
# - needs root and hugepages
# - build environment capabilities too unpredictable
# - certain workarounds needed to get running, needing root for some which is
#   not available in the build environment

# blacklist reasons:
# known upstream: http://www.dpdk.org/ml/archives/dev/2016-May/038849.html
# - KNI: we deliver via dkms but test doesn't match
# - power_acpi_cpufreq: in many environments blocked by other cpufreq
# - power_kvm_vm_autotest: no avail in all environments, only for virt power management e.g. /dev/virtio-ports/virtio.serial.port.poweragent.0
# - IVSHMEM fails in virtual environment
# - eal_flags needs at least 8 cpus for lcores test not to fail
# - pci doesn't initialize in all virt env causing command not found issues
# - rather slow performance tests not suited for regular build associated tests: ring_perf,mempool_perf,memcpy_perf,hash_perf,timer_perf

# Pass/Fail
# For now the autotest is too unreliable, so we run it to get some logs in
# different environments, but never (want to) fail until it is stable.
