pub unsafe fn write_raw(value: u64)

Write raw CR0 flags.

Does not preserve any values, including reserved fields.

Safety

This function is unsafe because it’s possible to violate memory safety through it, e.g. by disabling paging.

pub unsafe fn update<F>(f: F)

where F: FnOnce(&mut Cr0Flags),

Updates CR0 flags.

Preserves the value of reserved fields.

Safety
