6 bool "Check for stack overflows"
7 depends on DEBUG_KERNEL
9 config DEBUG_DECOMPRESS_KERNEL
10 bool "Using serial port during decompressing kernel"
11 depends on DEBUG_KERNEL
14 If you say Y here you will confirm the start and the end of
15 decompressing Linux seeing "Uncompressing Linux... " and
16 "Ok, booting the kernel.\n" on console.
18 config TEST_MISALIGNMENT_HANDLER
19 bool "Run tests on the misalignment handler"
20 depends on DEBUG_KERNEL
23 If you say Y here the kernel will execute a list of misaligned memory
24 accesses to make sure the misalignment handler deals them with
25 correctly. If it does not, the kernel will throw a BUG.
29 depends on DEBUG_KERNEL
31 Kprobes allows you to trap at almost any kernel address and
32 execute a callback function. register_kprobe() establishes
33 a probepoint and specifies the callback. Kprobes is useful
34 for kernel debugging, non-intrusive instrumentation and testing.
38 bool "Remote GDB kernel debugging"
39 depends on DEBUG_KERNEL
43 If you say Y here, it will be possible to remotely debug the kernel
44 using gdb. This enlarges your kernel ELF image disk size by several
45 megabytes and requires a machine with more than 16 MB, better 32 MB
46 RAM to avoid excessive linking time. This is only useful for kernel
47 hackers. If unsure, say N.
49 config GDBSTUB_IMMEDIATE
50 bool "Break into GDB stub immediately"
53 If you say Y here, GDB stub will break into the program as soon as
54 possible, leaving the program counter at the beginning of
55 start_kernel() in init/main.c.
58 bool "Console output to GDB"
61 If you are using GDB for remote debugging over a serial port and
62 would like kernel messages to be formatted into GDB $O packets so
63 that GDB prints them as program output, say 'Y'.
65 config GDBSTUB_DEBUGGING
66 bool "Debug GDB stub by messages to serial port"
69 This causes debugging messages to be displayed at various points
70 during execution of the GDB stub routines. Such messages will be
71 displayed on ttyS0 if that isn't the GDB stub's port, or ttySM0
74 config GDBSTUB_DEBUG_ENTRY
75 bool "Debug GDB stub entry"
76 depends on GDBSTUB_DEBUGGING
78 This option causes information to be displayed about entry to or exit
79 from the main GDB stub routine.
81 config GDBSTUB_DEBUG_PROTOCOL
82 bool "Debug GDB stub protocol"
83 depends on GDBSTUB_DEBUGGING
85 This option causes information to be displayed about the GDB remote
86 protocol messages generated exchanged with GDB.
88 config GDBSTUB_DEBUG_IO
89 bool "Debug GDB stub I/O"
90 depends on GDBSTUB_DEBUGGING
92 This option causes information to be displayed about GDB stub's

96 bool "Debug GDB stub breakpoint management"
97 depends on GDBSTUB_DEBUGGING
99 This option causes information to be displayed about GDB stub's
100 breakpoint management.
