Summary

XSAVE stands for similar x86 instruction xsave which places extended processor state into a memory area. The saving can be initiated by any userspace application at any moment and size of the memory frame depends on processor features and may vary between different models. Thus if checkpoint and restore are done on different processors the next call to xsave may corrupt memory if sizes mismatch.
