If you are working on safety-critical systems (automotive, avionics, medical devices) or need ultra-low latency without sacrificing CPU utilization, GenP deserves your attention. Generalized Partitioning is a memory and resource management strategy that combines the predictability of static partitioning with the flexibility of dynamic allocation .
// Borrow from global pool (temporary) void *borrowed = genp_borrow(part, 256 * 1024, 100); // 100 ms timeout genp linux
The kernel ensures that if genp_return() is not called within 100 ms, the global reclaim thread forcefully revokes the memory—even if it means invalidating the process’s mapping (handled via SIGSEGV recovery in safe designs). You might think: “Can’t cgroups limit memory and mlockall() lock pages?” If you are working on safety-critical systems (automotive,
When you hear "memory management" in Linux, you likely think of the Buddy Allocator, slab , or malloc . But there is a lesser-known, powerful concept used in specialized real-time and embedded Linux kernels: Generalized Partitioning (GenP) . You might think: “Can’t cgroups limit memory and
// Return borrowed memory early genp_return(borrowed);
