Header Files

For Solaris 7 DDI/DKI compliance, drivers are allowed to include only the kernel header files listed in the synopsis sections of Section 9 of the Solaris 2.6 Reference Manual. All allowed kernel header files are now located in the /usr/include/sys directory.

New header files all drivers must include are <sys/ddi.h> and <sys/sunddi.h>. These two headers must appear last in the list of kernel header include files.
