Instance Method Details

#detach_time ⇒ Integer

Seconds in CLOCK_BOOTTIME of when Page Pool was detached by the driver. Once detached Page Pool can no longer be used to allocate memory. Page Pools wait for all the memory allocated from them to be freed before truly disappearing. "Detached" Page Pools cannot be "re-attached", they are just waiting to disappear. Attribute is absent if Page Pool has not been detached, and can still be used to allocate new memory.

Returns:

  • (Integer)
