Is the GPIO memory mapped somewhere?  I need to read/write the pins at very high speed, so I'd like access as close to the hardware as possible.
Thanks

see this link for C++ library

see this link for python gpio control

Both links are useful for C.  The Python module is a wrapper;  the underlying C code is useful.  The C++ library is a good start too.  Yes, the gpio(s) are mapped in /dev/mem

Please see the A64 datasheet, and the A64 user manual also.
