“Kael, no! You’ll lose telemetry, strategy, everything!”
In the Linux kernel, fpstate (or struct fpstate ) represents the memory structure used to save and restore the and Extended State (XSTATE) of a CPU. Modern processors use advanced registers (like AVX-512 or AMX) that are much larger than standard integer registers.
The "best" way to handle fpstate in the context of vDSO or high-speed system calls involves a concept known as and XSAVE optimizations . vsyscall and vDSO · Linux Inside - 0xax
