rhel6 32bit架構下 Transparent Huge Pages (THP) 特性被啟用麼？

原文标題：

Is the Transparent Huge Pages (THP) feature enabled on RHEL 6 (x86) 32-bit architecture

環境

• Red Hat Enterprise Linux 6 (x86) 32-bit
• Transparent Huge Pages (THP)
• redhat_transparent_hugepage

問題

• Is Transparent Huge Pages (THP) feature enabled on Red Hat Enterprise Linux 6 (x86) 32-bit architecture ?

• Why Red Hat Enterprise Linux 6 (x86) 32-bit server does not have "redhat_transparent_hugepage" directory inside /sys/kernel/mm/?

  Eg:

​​Raw​​

# cat /sys/kernel/mm/redhat_transparent_hugepage/{defrag,enabled}
cat: /sys/kernel/mm/redhat_transparent_hugepage/defrag: No such file or directory
cat: /sys/kernel/mm/redhat_transparent_hugepage/enabled: No such file or directory
      

決議

• The Transparent Huge Pages (THP) feature is not present on the 32-bit (x86) version of Red Hat Enterprise Linux 6. Install the 64-bit (x86_64) version to enable this feature.
