Overview

Version 3.1.7 of the VME6U6 / VME9U12 host software includes the following changes:

• Modification to the SunOS 4.1.x Device Driver to allow up to 21 VME6U6 boards per system.

• Modification to the SunOS 2.x Device Driver for Solaris 2.7 compatibility.

• The merging of dspioctl.h for SunOS and Solaris systems.

Modification to SunOS 4.1.x Device Driver

The VME6U6/VME9U12 device driver for SunOS 4.1.x has been modified to allow up to 21 VME6U6 boards per system when using a single major device number for the dsp driver. This is accomplished by not allocating device nodes for the resources that are not used for VME6U6 boards. Note that this requires that VME9U12 boards not be used in systems installed with this new option.

If you configure the device driver and your kernel to use a single major device number for all VME6U6/VME9U12 boards by uncommenting the following line in dspdrv_options.h:

      #define DSP_SINGLE_MAJOR

and you want to install more than 14 VME6U6 boards in the system, also uncomment the following lin in dspdrv_options.h:

      #define DSP_VME6U6_ONLY

This will allow up to 21 VME6U6 boards to be installed but you may not use VME9U12 boards in the system.

Using this configuration, you must also create (or re-create) the device nodes for the boards running the makedspdev script with the following options:

      makedspdev  <num_boards>  <major_dev_number>  VME6U6

This will create device nodes for the number of boards specified with only the minor device entries required for VME6U6 boards.

Modification to Solaris 2.x Device Driver Code

The VME6U6/VME9U12 device driver code for Solaris 2.x is modified for compiler compatibility under Solaris 2.7. In Solaris 2.7 the prototype for the ioctl function has changed and the names of the peek and poke functions have changed.

Note that these changes do not provide compatibility with the 64-bit version of Solaris 2.7.

Merged dspioctl.h for SunOS and Solaris

There is now just one version of the dspioctl.h header file for both SunOS and Solaris (Solaris 1.x and Solaris 2.x). It is is now distributed in the $CAC/include directory rather than in the separate device driver source directories. The top-level Makefile in $CAC/dsp no longer copies dspioctl.h from the device driver directory to the $CAC/include directory.

Those upgrading their installation from a previous release of the VME6U6/VME9U12 software, should delete the old dspioctl.h files from the $CAC/bdsp/dspsoldev directory before compiling the device driver.

A copy of dspioctl.h is distributed in the $CAC/dsp/dspsundev directory to make it easier to copy the necessary files to the directory used for building SunOS 4.1.x kernels.
