pub unsafe fn _xsaves(mem_addr: *mut u8, save_mask: u64)Available on (x86 or x86-64) and target feature
xsave,xsaves only.Expand description
Performs a full or partial save of the enabled processor states to memory at
mem_addr
xsaves differs from xsave in that it can save state components
corresponding to bits set in IA32_XSS MSR and that it may use the
modified optimization. State is saved based on bits [62:0] in save_mask
and XCR0. mem_addr must be aligned on a 64-byte boundary.
