This one came up on netbsd again. You can do crude SMP by simply locking the kernel when a proc enters it. This works ok for 2-4 processors, and works well enough that AIX/370 used it for a few years. Takes about 4KLOCS to implement. ron Ron Minnich |We can think of C++ as the Full Employment Act rminnich@earth.sarnoff.com |for Programmers. After all, with each compiler (609)-734-3120 |version change, you have to rewrite all your code.
