We have it built with TLE support in Ubuntu (starting in 15.04), SLES 12 (since SP2) and AT 9.0-0. However, it is only enabled by default in Ubuntu. For SLES and AT 9.0, the user has to set an env var to enable it (it's a hack). There is some work upstream to add a tunables framework to glibc. That will allow us to properly provide a way to users enable/disable TLE as they wish. That patch is almost in, and as soon as it's committed, we'll start working on the tunable for TLE. -- Carlos Eduardo Seo Software Engineer - Linux on Power Toolchain cseo@linux.vnet.ibm.com
