Dsp cmd

Template:Hierarchy header dsp_cmd can be used to interact with the PCI fibre card DSP program directly. It makes screwing up the fibre card program and/or your PCI bus simple. Use with caution.

Usage

dsp_cmd [-i] [-q] [-p] [-n CARD] [-f FILE | -x COMMAND]
dsp_cmd [-h | -?]

where:
 -h / -?    show this help screen
 -i         interactive mode
 -q         quiet mode (report errors only)
 -p         don't prefix output lines
 -f FILE    read commands from FILE
 -n CARD    communicate with PCI fibre card number CARD.  Ignored unless Multicard MAS has been enabled.
 -x COMMAND execute command COMMAND

Commands

COMMAND is one of (case insenstive):

• VERS: Report the version number of the DSP code. Syntax is:

VERS

• READ: Read data from the DSP memory banks. Syntax is:

READ bank addr

where

• bank is the memory bank to read, one of X, Y, P
• addr is the memory address

• WRITE: Write data to the DSP memory banks. Syntax is:

WRITE bank addr value

where

• bank is the memory bank to write, one of X, Y, P
• addr is the memory address
• value is the datum to write

• RESET: Reset the DSP program. This is equivalent to the dsp_reset command in mce_cmd. Syntax is:

RESET

• RESET_MCE: Reset the MCE. This is equivalent to the mce_reset command in mce_cmd. Syntax is:

RESET_MCE

• QT_SET: Set a QT (quiet transfer) mode parameter. Syntax is:

QT_SET param value

where

• param is the parameter to set, one of BASE, DELTA, NUMBER, INFORM, SIZE, TAIL, HEAD, DROPS, FLUSH, ENABLE, BURST
• value is the parameter value to write
