DPT Software Release Notes
Version 0.94

April 26, 2001

Overview

The following changes are introduced in this release:

Additions and fixes to the DPT Library
Additions and fixes to the Solaris Device Driver
Additions and fixes to the Embedded Code
New and modified Diagnostic Programs

Note: This release includes new embedded code and FPGA configurations. Customers must run dpflashup after installation to receive the full benefit of this update. It will be necessary to cycle power on the system after updating the flash.

Note: The device names have changed after Version 0.91. The old driver used V6M6 style device names:

    /dev/pci0a    /dev/pci0b    /dev/pci0c    /dev/pci0d    /dev/pci0e    
    /dev/pci0f    /dev/pci0g    /dev/pci0h    /dev/pci0q    /dev/pci0t

    /dev/dpt0     /dev/dpt0a     /dev/dpt0b
    /dev/dpt0chan /dev/dpt0tdm   /dev/dpt0vsp

make install-drv

DPT Library

The changes in the DPT library include modification to support the Window 2000 device driver, bug fixes and new utility functions:

Bug Fixes

pci_open sets config.mod_par_max to the last byte of range rather then the first byte after the range.

New Functions

New function, pci_open_chanex, is an extension to the normal pci_open_chan function. The new argument is a pointer to a structure of type chanopen_t. Presently this structure consists of a single element tx_start_delay. tx_start_delay controls the number of data elements the baseboard MIPS should buffer up prior to starting to transmit the data. In software version 0.93 the threshold was hard coded to 8000 elements or a one second of delay.
New functions, pci_set_dpbuffer and pci_get_dpbuffer, may be used to set and get the size of the dual-port buffers.
New functions to support the dm_12c549 module.
New functions in dp_iter.c for module and board iteration routines.
