hugeedit - Set default policy for backing text and data with hugepages


hugeedit binary
hugeedit [options] binary


hugectl runs processes with a specific policy for backing memory regions with hugepages. Ordinarily when processes are relinked with libhugetlbfs using the recommended linking method, either hugectl is required on each execution or environment variables must be set for each execution. hugeedit can be used to set bits in the ELF header that determine if the text or data segments are backed by default without further intervention.

If no arguments are specified, hugeedit will display what the current defaults for each segment in a binary are. The available options are

Back the text segments of the binary by default.
Back the data segments of the binary by default
Back all segments using small pages by default
