Overview

Version 3.1.6 of the VME6U6 / VME9U12 host software includes the following changes:

• Bug fix for the vmedspdiag program.

• Minor bug fix for the SunOS 4.1.x Device Driver.

• Bug fixes for the DG/UX Device Driver.

Bug fix for vmedspdiag for Codec Diagnostics

The vmedspdiag interactive diagnostic shell program required changes to be compatible with the changes made to the d3scp, d3hscp and d3auxscp diagnostic programs in the previous release.

Minor bug fix for the SunOS 4.1.x Device Driver

When the SunOS 4.1.x device driver is configured to use separate major device numbers for each VME6U6 or VME9U12 board and not all the boards configured in the system are installed the driver displays the following error messages when a program tries to access the missing boards:

     dspdrv: board_info entry not found for devno n
     dspopen: board number out of range.

These messages are informational in nature and the driver will properly return an error indicating that the device does not exist. However, the messages are intended to be displayed only if the TRACE options are set in dspdrv_options.h when the driver and kernel are compiled. The new version corrects this problem.

Bug fixes for the DG/UX Device Driver

Some versions of DG/UX did not define values for the UAC_READ_ACCESS, UAC_WRITE_ACCESS, UAC_EXECUTE_ACCESS and UAC_NO_ACCESS macros and they were defined in the file dev_dsp_driver.h. These definitions are now conditional upon the macros being defined in system header files to avoid compiler errors caused by multiple definitions.

An error calling the system function, hdl_get_my_process_handle(), in dev_dsp_open() for DG/UX versions prior to R4.10 has been corrected in the file, dev_dsp_driver.c.

In addition, the comments in the Makefile and dsp_dsp_options.h are clarified to better explain the settings of the TARGET_BINARY and various DGUX version macros.
