+ * Define an assert macro that code within nvgpu can use.
+ *
+ * The goal of this macro is for debugging but what that means varies from OS
+ * to OS. On Linux wee don't want to BUG() for general driver misbehaving. BUG()
+ * is a very heavy handed tool - in fact there's probably no where within the
+ * nvgpu core code where it makes sense to use a BUG() when running under Linux.
+ *
+ * However, on QNX (and POSIX) BUG() will just kill the current process. This
+ * means we can use it for handling bugs in nvgpu.
+ *
+ * As a result this macro varies depending on platform.
