1.27.0[][src]Function core::arch::x86::_xsaves

pub unsafe fn _xsaves(mem_addr: *mut u8, save_mask: u64)
This is supported on x86 and target feature xsave,xsaves only.

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.
