This brought in some additional config items that were hidden with NUMA off. I have made best attempts, but let me know if you would like any of these to change:
CONFIG_EMU_SIZE=0x10000000 CONFIG_NODES_SHIFT=4 CONFIG_NUMA_BALANCING_DEFAULT_ENABLED=y CONFIG_NUMA_BALANCING=y CONFIG_NUMA_EMU=y CONFIG_NUMA=y
I've asked IBM for a review of the config options and here is the reply:
"The config option CONFIG_NUMA_BALANCING_DEFAULT_ENABLED should be *disabled *. Automatic balancing does not make sense for FAKE NUMA and just produces overhead by moving around memory.
The rest looks good to me."
Please update the config accordingly.
That sounds perfectly reasonable. I have updated the config for today's build.
Thanks, Justin
