arch:: x86_64:: _xsaves64
pub unsafe fn _xsaves64(mem_addr: *mut u8, save_mask: u64)
Performs a full or partial save of the enabled processor states to memory at
xsaves differs from xsave in that it can save state components
corresponding to bits set in
MSR and that it may use the
modified optimization. State is saved based on bits
mem_addr must be aligned on a 64-byte boundary.
