DATAPATH Q-PC Hardware Characteristics Driver Controller
SUMMARY
=======
QPCHWCTL is the Datapath Q-PC hardware characteristics driver controller.
Its purpose is to display and change the hardware characteristics stored in
the Q-PC Hardware Characteristics Driver. Its main use is in trouble shooting.
The Datapath Q-PC Initialization program QINIT, and the Datapath Configuation
File Editor QCONFIG, are used to set the hardware characteristics in normal
use.
USAGE
=====
Displaying information.
qpchwctl
- display the settings for the first qpc
qpchwctl -q <number>
- display the settings for qpc <number>
qpchwctl -a
- display the settings for all the qpcs known to QPCHW
The standard display format is as follows. It is hopefully self explanatory.
Q-PC BA IRQ DMA FLAGS XMEM YMEM FOLD PLANES
1 0x300 10 7 0x1 2048 1024 1024 0x0f
If the qpc number does not have information set, the qpc number is out
of range, or the hardware characteristics driver is not installed, an
appropriate message is printed out.
Changeing information.
qpchwctl -q <number> -b <base address> -i <irq> -d <dma> -x <xsize> -y <ysize>
-f <mem fold> -p <planes>
Set the selected characteristic(s) for qpc <number>.
If -q <number> is ommitted, the first qpc is used.
The given characteristics are merged in with the existing ones. If no
characteristics are set, then the default values (see qpchw.doc) are set for
characteristics not specified on the command line.
The resulting characteristics are displayed.
