, the focus is on performance. vDSO allows certain system calls (like getting the current time) to happen in "user space" without a full, slow jump into the kernel "system space". Security Implications: Improperly handling
Use compacted XSAVE format to reduce the size of the state buffer. fpstate vso best
Many encryption algorithms use FPU registers for speed; keeping this state secure and isolated is paramount. Real-time Systems: In robotics or aviation, the "best" , the focus is on performance
