MEM(4) | Kernel Interfaces Manual (Acorn32) | MEM(4) |
Kernel virtual memory is accessed through the interface /dev/kmem in the same manner as /dev/mem. Only kernel virtual addresses that are currently mapped to memory are allowed.
On Acorn RiscPC, A7000(+) and RC7500 systems the I/O memory space (podule space and SuperIO) begins at physical address 0x03000000 and runs to 0x033fffff. On the RiscPC, EASI space runs from 0x08000000 to 0x0fffffff. The per-process data size for the current process is UPAGES long, and starts at VM_MAXUSER_ADDRESS.
