How to enable HugePages-1GB?

[andyndang]

Hi all,

Any suggestions on how to enable hugepages-1GB on a bottlerocket instance? I see another discussion about transparent hugepages (#1989) (I don't want to turn this on) and there seems to be some possible configurations under settings.boot.* but it's unclear from the documentation.

Thank you

Okay I finally found the config that worked:

[settings.boot.kernel-parameters]
"default_hugepagesz" = [ "1G" ]
"hugepagesz" = [
 "1G"
]
"hugepages" = [
 "10"
]

[settings.boot]
reboot-to-reconcile = true
