Kernel

Summary

The engine's core library (Dantelion2, "ClassLibrary/Core/Kernel" in its source paths): thin wrappers around the PS4 kernel for threads, mutexes and condition variables, which report every unexpected result through the engine's fatal error function (0x024b55b0, file, line, message).

kernel_condition_wait (0x02483e80) waits on a condition variable: forever when the timeout is -1, else with a timed wait that returns -3 on timeout. It is called about 40 times a frame in gameplay. The community frame-rate patches replace its timed-wait call with a return that would jump to a garbage address if it ran; every wait recorded in gameplay is untimed, so it never does.

Patch points

30 FPS++, 60 FPS++, 90 FPS++ and Uncap FPS++ write a return over the timed-wait call in 0x02483e80 (see above); our replacement keeps the original behaviour.

Open questions

Which objects the ~40 condition waits per frame belong to (job queues, the render thread?).
