Title:
s390/kconfig: CONFIG_NUMA without CONFIG_NUMA_EMU does not make any
sense on s390x
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Released
Bug description:
== Comment: #0 - Hendrik Brueckner - 2016-03-15 06:33:03 ==
For NUMA, ensure the setting of these kernel configuration for s390x:
# CONFIG_NUMA_BALANCING_DEFAULT_ENABLED is not set
CONFIG_NUMA_EMU=y
CONFIG_EMU_SIZE=0x10000000
CONFIG_NUMA without CONFIG_NUMA_EMU does not make any sense. s390 does not provide hardware topology information. However, we do support fake NUMA to improve performance issues seen with very large memory configurations. Therefore, CONFIG_NUMA_EMU has to be enabled.
Given that we only support fake NUMA
CONFIG_NUMA_BALANCING_DEFAULT_ENABLED should be disabled, since it
moves pages without any benefit but costs additional cpu cycles.
