34: * HISTORY
35: * Revision 1.1.1.1 1997/09/30 02:44:35 wsanchez
36: * Import of kernel from umeshv/kernel
37: *
38: *
39: * 21-Jan-92 Doug Mitchell at NeXT
40: * Added support for m88k uxpr module.
41: *
42: * 22-Jun-89 Mike DeMoney (mike) at NeXT.
43: * Put xpr macro in {}'s so it wouldn't steal a following "else" clause.
44: *
45: * Revision 2.10 89/05/30 10:38:29 rvb
46: * Removed Mips crud.
47: * [89/04/20 af]
48: *
49: * Revision 2.9 89/03/09 20:17:45 rpd
50: * More cleanup.
51: *
52: * Revision 2.8 89/02/25 18:11:09 gm0w
53: * Kernel code cleanup.
54: * Made XPR_DEBUG stuff always true outside the kernel
55: * [89/02/15 mrt]
56: *
57: * Revision 2.7 89/02/07 01:06:11 mwyoung
58: * Relocated from sys/xpr.h
59: *
60: * Revision 2.6 89/01/23 22:30:39 af
61: * Added more flags, specific to Mips. Should eventually integrate,
62: * but for now there are conflicts.
63: * Also made it usable from assembly code.
64: * [89/01/05 af]
65: *
66: * Revision 2.5 88/12/19 02:51:59 mwyoung
67: * Added VM system tags.
68: * [88/11/22 mwyoung]
69: *
70: * Revision 2.4 88/08/24 02:55:54 mwyoung
71: * Adjusted include file references.
72: * [88/08/17 02:29:56 mwyoung]
73: *
74: * 9-Apr-88 Daniel Julin (dpj) at Carnegie-Mellon University
75: * Added flags for TCP and MACH_NP debugging.
76: *
77: * 6-Jan-88 Michael Young (mwyoung) at Carnegie-Mellon University
78: * Make the event structure smaller to make it easier to read from
79: * kernel debuggers.
80: *
81: * 16-Mar-87 Mike Accetta (mja) at Carnegie-Mellon University
82: * MACH: made XPR_DEBUG definition conditional on MACH
83: * since the routines invoked under it won't link without MACH.
84: * [ V5.1(F7) ]
85: */
86: /*
87: * Include file for xpr circular buffer silent tracing.
88: *
89: */
90:
91: /*
92: * If the kernel flag XPRDEBUG is set, the XPR macro is enabled. The
93: * macro should be invoked something like the following:
94: * XPR(XPR_SYSCALLS, ("syscall: %d, 0x%x\n", syscallno, arg1));
95: * which will expand into the following code:
96: * if (xprflags & XPR_SYSCALLS)
97: * xpr("syscall: %d, 0x%x\n", syscallno, arg1);
98: * Xpr will log the pointer to the printf string and up to 6 arguments,
99: * along with a timestamp and cpuinfo (for multi-processor systems), into
100: * a circular buffer. The actual printf processing is delayed until after
101: * the buffer has been collected. It is assumed that the text/data segments
102: * of the kernel can easily be reconstructed in a post-processor which
103: * performs the printf processing.
104: *
105: * If the XPRDEBUG compilation switch is not set, the XPR macro expands
106: * to nothing.
