Expand description

A 512-byte memory region for the FXSAVE/FXRSTOR instruction to save and restore the x87 FPU, MMX, XMM, and MXCSR registers.

This is also the legacy region (offset 0..512) at the head of the XSAVE/XRSTOR area, so it doubles as the start of UserXstate.

See https://www.felixcloutier.com/x86/fxsave for more details.
