63 | * If the kernel flag XPRDEBUG is set, the XPR macro is enabled. The |
64 | * macro should be invoked something like the following: |
65 | * XPR(XPR_SYSCALLS, "syscall: %d, 0x%x\n", syscallno, arg1, 0,0,0); |
66 | * which will expand into the following code: |
67 | * if (xprflags & XPR_SYSCALLS) |
68 | * xpr("syscall: %d, 0x%x\n", syscallno, arg1, 0,0,0); |
69 | * Xpr will log the pointer to the printf string and up to 5 arguements, |
70 | * along with a timestamp and cpuinfo (for multi-processor systems), into |
71 | * a circular buffer. The actual printf processing is delayed until after |
72 | * the buffer has been collected. It is assumed that the text/data segments |
73 | * of the kernel can easily be reconstructed in a post-processor which |
74 | * performs the printf processing. |
75 | * |
76 | * If the XPRDEBUG compilation switch is not set, the XPR macro expands |
77 | * to nothing. |
