54 * Include file for xpr circular buffer silent tracing.

57/*
58 * If the kernel flag XPRDEBUG is set, the XPR macro is enabled. The
59 * macro should be invoked something like the following:
60 * XPR(XPR_SYSCALLS, "syscall: %d, 0x%x\n", syscallno, arg1, 0,0,0);
61 * which will expand into the following code:
62 * if (xprflags & XPR_SYSCALLS)
63 * xpr("syscall: %d, 0x%x\n", syscallno, arg1, 0,0,0);
64 * Xpr will log the pointer to the printf string and up to 5 arguements,
65 * along with a timestamp and cpuinfo (for multi-processor systems), into
66 * a circular buffer. The actual printf processing is delayed until after
67 * the buffer has been collected. It is assumed that the text/data segments
68 * of the kernel can easily be reconstructed in a post-processor which
69 * performs the printf processing.
70 *
71 * If the XPRDEBUG compilation switch is not set, the XPR macro expands
72 * to nothing.
