Traditionally, the kernel could assume a fixed size for the floating-point state. However, modern x86 architectures use , where the amount of data saved during a context switch depends on which CPU features (like AVX, AVX-512, or AMX) the application actually uses.

By treating the FPU state as a variable object, the kernel avoids allocating massive, worst-case memory buffers for every single process. fpstate vso

As modern CPUs have evolved from basic x87 floating-point units to advanced vector processing extensions like AVX-512, the "size" of a process's register state has grown significantly. The framework was introduced to handle this "variable" nature of register state efficiently within the kernel. Core Concepts of Fpstate VSO Traditionally, the kernel could assume a fixed size
