3 source "lib/Kconfig.debug"
5 config SH_STANDARD_BIOS
6 bool "Use LinuxSH standard BIOS"
8 Say Y here if your target has the gdb-sh-stub
9 package from www.m17n.org (or any conforming standard LinuxSH BIOS)
10 in FLASH or EPROM. The kernel will use standard BIOS calls during
11 boot for various housekeeping tasks (including calls to read and
12 write characters to a system console, get a MAC address from an
13 on-board Ethernet interface, and shut down the hardware). Note this
14 does not work with machines with an existing operating system in
15 mask ROM and no flash (WindowsCE machines fall in this category).
18 config EARLY_SCIF_CONSOLE
19 bool "Use early SCIF console"
20 depends on CPU_SH4 || CPU_SH2A && !SH_STANDARD_BIOS
23 bool "Early printk support"
24 depends on SH_STANDARD_BIOS || EARLY_SCIF_CONSOLE
26 Say Y here to redirect kernel printk messages to the serial port
27 used by the SH-IPL bootloader, starting very early in the boot
28 process and ending when the kernel's serial console is initialised.
29 This option is only useful porting the kernel to a new machine,
30 when the kernel may crash or hang before the serial console is
31 initialised. If unsure, say N.
33 config DEBUG_STACKOVERFLOW
34 bool "Check for stack overflows"
35 depends on DEBUG_KERNEL
37 This option will cause messages to be printed if free stack space
38 drops below a certain limit.
40 config DEBUG_STACK_USAGE
41 bool "Stack utilization instrumentation"
42 depends on DEBUG_KERNEL
44 Enables the display of the minimum amount of free stack which each
45 task has ever had available in the sysrq-T and sysrq-P debug output.
47 This option will slow down process creation somewhat.
50 bool "Include KGDB kernel debugger"
53 Include in-kernel hooks for kgdb, the Linux kernel source level
54 debugger. See <http://kgdb.sourceforge.net/> for more information.
55 Unless you are intending to debug the kernel, say N here.
57 menu "KGDB configuration options"
60 config MORE_COMPILE_OPTIONS
61 bool "Add any additional compile options"
63 If you want to add additional CFLAGS to the kernel build, enable this
64 option and then enter what you would like to add in the next question.
65 Note however that -g is already appended with the selection of KGDB.
67 config COMPILE_OPTIONS
68 string "Additional compile arguments"
69 depends on MORE_COMPILE_OPTIONS
72 bool "Enter KGDB on NMI"
76 bool "Include KGDB thread support"
79 config SH_KGDB_CONSOLE
80 bool "Console messages through GDB"
84 bool "Allow SysRq 'G' to enter KGDB"
87 config KGDB_KERNEL_ASSERTS
88 bool "Include KGDB kernel assertions"
