+description: |
+ This section describes configuration options related to adapting
+ RTEMS behavior to be aligned with the FACE Technical Standard.
+ The FACE Technical Standard is a product of the FACE Consortium
+ which operates under the Open Group. The FACE Consortium was founded
+ by avionics organizations to improve the portability of cockpit software
+ across various platforms. It addresses technical and business concerns.
+
+ Most important from an RTEMS perspective, the FACE Technical Standard
+ defines four POSIX profiles: Security, Safety Base, Safety Extended, and
+ the General Purpose Profile. Each has an increasingly larger subset of
+ POSIX APIs. In the Security and Safety profiles, ARINC 653 is required.
+ It is optional in the General Purpose Profile.
+
+ The RTEMS Project has been tracking alignment with the FACE POSIX profiles
+ and they are included in the "RTEMS POSIX 1003.1 Compliance Guide."

+ If this configuration option is defined, then POSIX timers may
+ not be created to use the CLOCK_REALTIME. Per POSIX, this is allowed
+ behavior but per the FACE Technical Standard, it is not. Using POSIX
+ timers based on CLOCK_REALTIME (e.g., time of day) is unsafe for
+ real-time safety systems as setting CLOCK_REALTIME will perturb any
+ active timers.
+
+ If this option is not defined, POSIX timers may be created to use the
+ CLOCK_REALTIME in compliance with the POSIX specification.
