The gbus utilites are released with MRUA/dev/poeoring under llad_smallapps directory of MRUA_src, they can be built by "make smallapps". 

The gbus utilities include:
***************************
 a) read/write/fill through gbus for byte/word/longword

    1) gbus_read_uint32
         Usage: ./gbus_read_uint32 <address>
    2) gbus_read_uint16
         Usage: ./gbus_read_uint16 <address>
    3) gbus_read_uint8
         Usage: ./gbus_read_uint8 <address>
    4) gbus_write_uint32
         Usage: ./gbus_write_uint32 <address> <data>
    5) gbus_write_uint16
         Usage: ./gbus_write_uint16 <address> <data>
    6) gbus_write_uint8
         Usage: ./gbus_write_uint8 <address> <data>
    7) gbus_fill
         Usage: ./gbus_fill <address> <data> <size>

  b) read/write a file (binary/text) through gbus
     1) gbus_read_bin_to_file
         Usage: ./gbus_read_bin_to_file <start> <size> <filename>
     2) gbus_write_bin_from_file
         Usage: ./gbus_write_bin_from_file <address> <filename> [<offset>] [<size>]
     3) gbus_read_uint32_to_file
         Usage: ./gbus_read_uint32_to_file <start> <size> <filename>
     4) gbus_write_uint32_from_file
         Usage: ./gbus_write_uint32_from_file <address> <filename> [<offset>] [<size>]

     example: gbus transfer test
          1) ./gbus_write_bin_from_file 0x10000000 getargs.c 
          2) ./gbus_read_bin_to_file 0x10000000 1746 test 
          3) diff getargs.c test 

  c) monitor/allocation bus bandwidth
           1) bw 
                Option: "r" for dump bandwidth, 
                         "d" and "e" for enable/disable channel
                         "w" to change the channel bandwidth
 
            Usage: ./bw
                Syntax: ./bw command --- example
                r
                d channel
                e channel
                w channel >4   (in percent!)
                w channel <12

            example: 
                ./bw r osd
Warning: ./bw: environment variable EM8XXX_SERVER not set. Using device 0
informative: sum bwmin =   1%
informative: sum bwmax =  494%
channel          gfx_in:   0% < bw <  49% <= limit 12%
channel        video_in:   0% < bw <  24% <= limit  3%
channel          main_Y:   1% < bw <  24% <= limit 12%
channel         main_UV:   0% < bw <  24% <= limit  6%
channel           pip_Y:   0% < bw <  24% <= limit  6%
channel          pip_UV:   0% < bw <  24% <= limit  3%
channel           vcr_Y:   0% < bw <  24% <= limit  6%
channel          vcr_UV:   0% < bw <  24% <= limit  3%
channel           crt_Y:   0% < bw <  24% <= limit  6%
channel          crt_UV:   0% < bw <  24% <= limit  3%
channel             osd:   0% < bw <  49% <= limit 12%
channel             spu:   0% < bw <  24% <= limit  6%
channel    gfxaccelx_in:   0% < bw <  49% <= limit  3%
channel    gfxaccely_in:   0% < bw <  49% <= limit  3%

   d) retrieve llad configuration (PCI ID, PCI class, Vendor,device,revision ID)
       1) llad_get_config
           usage:
          ./llad_get_config
            Warning: ./llad_get_config: environment variable EM8XXX_SERVER not set. Using device 0
            config is : 00:00.0 048000 1105:8634 1105:00c1 82

By the way, YAMON shell also support gbus read/write function.
