5 | config CROSSCOMPILE | |
6 | bool "Are you using a crosscompiler" | |
7 | help | |
8 | Say Y here if you are compiling the kernel on a different | |
9 | architecture than the one it is intended to run on. | |
10 | ||
11 | config CMDLINE | |
12 | string "Default kernel command string" | |
13 | default "" | |
14 | help | |
15 | On some platforms, there is currently no way for the boot loader to | |
16 | pass arguments to the kernel. For these platforms, you can supply | |
17 | some command-line options at build time by entering them here. In | |
18 | other cases you can specify kernel args so that you don't have | |
19 | to set them up in board prom initialization routines. | |

21 | config DEBUG_STACK_USAGE | |
22 | bool "Enable stack utilization instrumentation" | |
23 | depends on DEBUG_KERNEL | |
24 | help | |
25 | Enables the display of the minimum amount of free stack which each | |
26 | task has ever had available in the sysrq-T and sysrq-P debug output. | |
27 | ||
28 | This option will slow down process creation somewhat. | |

30 | config KGDB | |
31 | bool "Remote GDB kernel debugging" | |
32 | depends on DEBUG_KERNEL | |
33 | select DEBUG_INFO | |
34 | help | |
35 | If you say Y here, it will be possible to remotely debug the MIPS | |
36 | kernel using gdb. This enlarges your kernel image disk size by | |
37 | several megabytes and requires a machine with more than 16 MB, | |
38 | better 32 MB RAM to avoid excessive linking time. This is only | |
39 | useful for kernel hackers. If unsure, say N. | |
40 | ||
41 | config GDB_CONSOLE | |
42 | bool "Console output to GDB" | |
43 | depends on KGDB | |
44 | help | |
45 | If you are using GDB for remote debugging over a serial port and | |
46 | would like kernel messages to be formatted into GDB $O packets so | |
47 | that GDB prints them as program output, say 'Y'. | |

49 | config SB1XXX_CORELIS | |
50 | bool "Corelis Debugger" | |
51 | depends on SIBYTE_SB1xxx_SOC | |
52 | select DEBUG_INFO | |
53 | help | |
54 | Select compile flags that produce code that can be processed by the | |
55 | Corelis mksym utility and UDB Emulator. | |
56 | ||
57 | config RUNTIME_DEBUG | |
58 | bool "Enable run-time debugging" | |
59 | depends on DEBUG_KERNEL | |
60 | help | |
61 | If you say Y here, some debugging macros will do run-time checking. | |
62 | If you say N here, those macros will mostly turn to no-ops. See | |
63 | include/asm-mips/debug.h for debuging macros. | |
64 | If unsure, say N. | |
65 | ||
66 | config MIPS_UNCACHED | |
67 | bool "Run uncached" | |
68 | depends on DEBUG_KERNEL && !SMP && !SGI_IP27 | |
69 | help | |
70 | If you say Y here there kernel will disable all CPU caches. This will | |
71 | reduce the system's performance dramatically but can help finding | |
72 | otherwise hard to track bugs. It can also useful if you're doing | |
73 | hardware debugging with a logic analyzer and need to see all traffic | |
74 | on the bus. | |
