reggie_se(1)              BSD General Commands Manual             reggie_se(1)


NAME

     reggie_se -- read and modify hardware registers


SYNOPSIS

     reggie_se [-d dev] [-D type] [-i index] [-r] [-w val] [-s n] [-S val] [-c
               n] [-C] [-l] [-x] [-b b:e] [-v] [-h]


USAGE

     To read a register:

              reggie_se -r [-d devclass] [-D devname] [-i index] [-v] -n reg-
              ister_name

              reggie_se -r [-d devclass] [-D devname] [-i index] [-v] -a reg-
              ister_addr -B reg_size

     To write a register:

              reggie_se -w value [-d devclass] [-D devname] [-i index] [-v] -n
              register_name

              reggie_se -w value [-d devclass] [-D devname] [-i index] [-v] -a
              register_addr -B reg_size

     To set a bit or range of bits:

              reggie_se -s bit_index [-d devclass] [-D devname] [-i index]
              [-v] -n register_name

              reggie_se -s bit_index [-d devclass] [-D devname] [-i index]
              [-v] -a register_addr -B reg_size

              reggie_se -S value -b b:e [-d devclass] [-D devname] [-i index]
              [-v] -n register_name

              reggie_se -S value -b b:e [-d devclass] [-D devname] [-i index]
              [-v] -a register_addr -B reg_size

     To clear a bit or range of bits:

              reggie_se -c bit_index [-d devclass] [-D devname] [-i index]
              [-v] -n register_name

              reggie_se -c bit_index [-d devclass] [-D devname] [-i index]
              [-v] -a register_addr -B reg_size

              reggie_se -C -b b:e [-d devclass] [-D devname] [-i index] [-v]
              -n register_name

              reggie_se -C -b b:e [-d devclass] [-D devname] [-i index] [-v]
              -a register_addr -B reg_size

     To get a list of available registers:

              reggie_se -l [-d devclass] [-D devname]

     User supplied values are interpreted as follows:

                   Hexadecimal (base-16) if prefixed by '0x' or '0X'

                   Octal (base-8)        if prefixed by '0o' or '0O'

                   Binary (base-2)       if prefixed by '0b' or '0B'

                   Decimal (base-10)     if no prefix


DESCRIPTION

     reggie_se is used to read and modify hardware registers and physical mem-
     ory.

     -d dev   specify target device by class

              c cpu (DEFAULT)

              p pci device

     -D type  specify target device by name

              CPU: 750, 750FXDDR1, 750FXDDR2, 7400, 7410, 7450, 7455, 7447A,
                       7457, 970

              Memory: PhysAddr

              Expansion: PCI

     -i index

              a target all devices (e.g. CPUn)

              n target only device at index n (e.g. -i 0 = CPU0)

     -r       read register

     -w val   write val to register

     -s n     set register bit n

     -S val   set register bit range to val (specify bit range with -b option)

     -c n     clear register bit n

     -C       clear register bit range (specify bit range with -b option)

     -l       list registers and exit

     -x       list expansion devices (PCI) and exit

     -b begin:end
              specify bit index range from begin to end for -S and -C actions

     -v       verbose mode (prints bit definitions)

     -h       print usage information and exit
