Here’s a helpful write-up explaining the concept of in the context of Linux kernel’s FPU (Floating Point Unit) handling, particularly for x86 architecture.
: To save resources, the system might not allocate space for massive register states (like ARM's SVE) until the moment they are actually used. If a program never performs complex math, the kernel avoids the overhead of managing those registers. fpstate vso exclusive
: Ensuring that high-performance computing applications don't lose data in their vector registers when the kernel performs background optimizations.
