       kloadsrv - Invokes the kernel load server daemon

SYNOPSIS    [Toc]    [Back]

       /sbin/kloadsrv  [-V] [-f] [-d debug_level] [-k] [-log logfile]
 [-q]  [-s  kernel_symtab_file]  [kernel_object_filename]


       /sbin/kloadsrv [-w kernel_symtab_file] kernel_object_filename

OPTIONS    [Toc]    [Back]

       Displays the version of the kloadsrv command.  Causes  the
       kloadsrv  daemon  to remain in the foreground. By default,
       the daemon automatically places itself into the background
       after  it  initializes.   Specifies the level of debugging
       information. The debug_level is a small integer.  A  value
       of  zero  (0) disables debugging. Nonzero values from 1 to
       higher levels cause kloadsrv to display various  log  messages.
   Kills  the  kloadsrv  daemon,  if  it is running.
       Specifies that the debugging information is to be sent  to
       the specified log file. The logfilevariable must be specified
 as a full pathname. By default, the debugging  information
  is  sent  to  the  console  device,  /dev/console.
       Queries and prints the process id of the kloadsrv  daemon,
       if  it  is  running, or prints 0 otherwise.  Specifies the
       name of the kernel symbol table file. By default, the kernel
 symbol table file name is /vmunix.sym.  Specifies that
       the kloadsrv command write a kernel symbol table file  and
       then  exit.  When you specify the -w option, you must also
       specify a kernel_object_filename.

DESCRIPTION    [Toc]    [Back]

       This command invokes the kloadsrv daemon, which loads kernel
  modules into the kernel. Command options in the first
       line of the synopsis are valid when  you  invoke  kloadsrv
       automatically  during  system startup. The kloadsrv daemon
       typically starts during system startup as specified in the
       /etc/inittab  file. Options in the second line of the command
 synopsis are valid when you invoke kloadsrv  manually
       from the command line.

       In  the  first invocation form, the kernel_object_filename
       variable is the pathname of the file from which  the  running
 kernel was booted. In the second invocation form, the
       kernel_object_filename variable is not optional. You  must
       specify  a  value,  which is the path to any linked kernel
       image for which you want to generate a kernel symbol table
       file.

       If  you  omit  an argument for kernel_object_filename from
       the startup command line, the  kloadsrv  daemon  uses  the
       running kernel.

       Usually,   you   must   specify   an   argument  for  kernel_object_filename
 only if you moved  the  booted  kernel
       image  after  the  kernel  was  booted.  This  is required
       because the kloadsrv daemon uses the value returned by the
       following command:

       /usr/sbin/sizer -b

       The  sizer  command returns the default kernel object file
       name.

       For example, suppose you move the running kernel  as  follows:


       /sbin/mv /vmunix /vmunix.bak /sbin/mv /genvmunix /vmunix

       If  you then need to restart the kloadsrv daemon, you must
       invoke it as follows:

       /sbin/kloadsrv /vmunix.bak

       When moving the booted kernel, you should take great care.
       During  its  initialization,  the kloadsrv daemon builds a
       list of kernel symbols used by device drivers.  Moving  or
       overwriting  the  kernel  object file while in single user
       mode, can cause the addresses in this list of  symbols  to
       be  inaccurate.  The  addresses  in  the  list reflect the
       addresses in the new kernel,  not  the  addresses  in  the
       booted  kernel. This will cause problems if you then transition
 the system to multiuser mode.

       If the kernel object file does  not  exist,  the  kloadsrv
       daemon  reads  its  symbol information from the file named
       /vmunix.sym which is the default pathname for  the  kernel
       symbol  table.  You  can  specify an alternate path to the
       kernel symbol table file by using the -s option.

       When the  kloadsrv  daemon  initializes  itself,  it  puts
       itself  into  the  background  and enters its server loop,
       where it waits to receive and respond  to  load  requests,
       unload requests, and query requests. If you specify the -f
       option, the daemon remains in the foreground.

       You can invoke the kloadsrv daemon using the -w option  to
       create  a  kernel  symbol table file. You can then specify
       this symbol table file as an argument to the -s option, or
       copy  the  file  to  /vmunix.sym and use it as the default
       kernel symbol table file.

       When the kloadsrv daemon is invoked with the -w option  it
       runs  in  the foreground and never enters its server loop.
       After writing the symbol  table  file,  the  daemon  exits
       without performing any server functions.
