Subject: Memory Mapping under Linux
Date: 1 Feb 1993 04:13:58 GMT

Hi,
  I just got Linux 0.99pl4 running! It's incredible. Better than some
commercial OS's even....

  Ok, now my question: How does one do memory mapping (for accessing
memory mapped devices) under Linux from a user process? For SVR4, there
is the mmap function and for SCO there is the MAP_CLASS ioctl. Does one
have to write a device driver to map the memory or is there a mmap()
equivalent?

Thanks in advance,
mahesh
