It is always mapped the same way, regardless of what user process or kernel thread is running. In Pintos, kernel virtual memory is mapped one-to-one to physical memory, starting at @code{PHYS_BASE}. That is, virtual address -@code{PHYS_ADDR} accesses physical -address 0, virtual address @code{PHYS_ADDR} + @t{0x1234} access +@code{PHYS_BASE} accesses physical +address 0, virtual address @code{PHYS_BASE} + @t{0x1234} access physical address @t{0x1234}, and so on up to the size of the machine's physical memory.
