Overview

Version 3.3.0 SB32C2 host software includes the following changes:

• Support for 64-bit Solaris 2.7 kernel for the SB32C2 device driver..

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

Support for 64-Bit Solaris 2.7 Kernel

The SB32C2 code for the Solaris 2.x device driver is now compatible with 64-bit sparc architectures running Soalris 2.7. Currently, only the Sun WorkShop C compiler is supported.

To build the SB32C3 driver for 64-bit systems, the Makefile in the $CAC/sbdsp/sbdspsoldev directory must be edited to specify the driver installation directory, the compiler and flags.

The lines with the macros specifying where the driver is installed should be changed from:

      DRIVER_DIR =   /kernel/drv
      #DRIVER_DIR =   /kernel/drv/sparcv9

to:

      #DRIVER_DIR =   /kernel/drv
      DRIVER_DIR =   /kernel/drv/sparcv9

The macros defining the complier and flags should be edited to look like:

      #CC = $(GCC)
      CC = $(CCC)

      #CFLAGS = $(GCFLAGS)
      #CFLAGS = $(GCFLAGS)
      CFLAGS = $(CC64FLAGS)

When the "install" target is made on a 64-bit system the device driver code will be installed in the /kernel/drv/sparcv9 directory instead of /kernel/drv.

Note that the SB32C2 application library, support programs and diagnostics are still compiled as 32-bit applications. These are compatible with 64-bit Solaris 2.7. However, the SB32C2 host applicaiton library should not be linked with 64-bit applications.

Merged sbdspioctl.h for SunOS and Solaris

There is now just one version of the sbdspioctl.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/sbdsp no longer copies sbdspioctl.h from the device driver directory to the $CAC/include directory.

Those upgrading their installation from a previous release of the SB32C2 software, should delete the old sbdspioctl.h files from the $CAC/sbdsp/sbdspsundev and $CAC/sbdsp/sbdspsoldev directories before compiling the device driver.
