RHEA-2010:0056 - libhugetlbfs enhancement update

Synopsis

libhugetlbfs enhancement update

Type/Severity

Product Enhancement Advisory (none)

Topic

An updated libhugetlbfs package that adds a script to simplify huge page setup is now available.

Description

The libhugetlbfs library interacts with the Linux hugetlbfs to make large pages available to applications in a transparent manner.

This update adds the following enhancement.

• previously, huge pages worked well once configured but setting them up was a complicated, multi-step, potentially error-prone process. This updated package includes a script -- huge_page_setup_helper -- that asks for three pieces of data and then sets up huge pages for use based on the answers provided. The three data points required by the script are the memory to allocate to huge pages and the group and users who should be allowed access to the huge pages. (BZ#523346)

All huge pages users should install this updated package which includes this enhancement.

Solution
