 NAME
      diag0 - diagnostic interface to I/O subsystem

 DESCRIPTION
      diag0 is the diagnostic pseudo-driver used by the on-line diagnostic
      subsystem.  The kernel sends diagnostic events here for logging by the
      diagnostic subsystem.  The diagnostic subsystem also sends diagnostic
      requests to the kernel via diag0.

 WARNINGS
      If the diagnostic subsystem does not read diagnostic events from diag0
      as fast as they are logged by the kernel, a warning message Warning:
      DIAG0 -- message queue full appears on the console.

 AUTHOR
      diag0 was developed by HP.
