Functions

translated_byte_buffer

Create mutable Vec slice in kernel space from ptr in other address space. NOTICE: the content pointed to by the pointer ptr can cross physical pages.

translated_ref

translate a pointer ptr in other address space to a immutable u8 slice in kernel address space. NOTICE: the content pointed to by the pointer ptr cannot cross physical pages, otherwise translated_byte_buffer should be used.

translated_refmut

translate a pointer ptr in other address space to a mutable u8 slice in kernel address space. NOTICE: the content pointed to by the pointer ptr cannot cross physical pages, otherwise translated_byte_buffer should be used.

translated_str

Create String in kernel address space from u8 Array(end with 0) in other address space
