RTEMS | Deterministic Hedged Read Library (DHRL) for DRAM Tail Latency Mitigation (#5548)

[Wayne Thornton (@wmthornton-dev)]

Wayne Thornton commented on a discussion: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5548#note_148536


As of April 14th, 2026:

- [x] `dhrl_init()` correctly spawns and pins worker threads using the RTEMS Classic API.

- [x] `dhrl_fetch_data()` correctly wakes workers, executes the race, and returns the valid pointer via C11 Atomics and RTEMS Event Sets without deadlocking.

- [x] Library compiles cleanly via `waf` and integrates into the `cpukit` build structure gated by compiler flags.

Testing is ongoing for validation and volatile pointers. Will also be locating and running tests on physical hardware as available.
