Vso Work - Fpstate

Would you like a focused article for one of these interpretations (kernel/hypervisor integration, or a software library API), or do you have a specific platform in mind (x86_64, ARM, Linux, Windows)?

Because registers like AVX-512 and AMX feature thousands of bits of data, the kernel cannot perform lazy or slow saves during context switches without tanking system throughput. Thus, the kernel uses hardware-accelerated instructions like XSAVE , XSAVES , XRSTOR , and XRSTORS to map the active CPU register state directly into memory buffers defined by fpstate . 2.
