bool "Check for stack overflows"

help
This option will cause messages to be printed if free stack space
drops below a certain limit.
config DEBUG_STACK_USAGE
bool "Stack utilization instrumentation"
- depends on DEBUG_KERNEL && PPC64

help
Enables the display of the minimum amount of free stack which each
task has ever had available in the sysrq-T and sysrq-P debug output.
This option will slow down process creation somewhat.
+config HCALL_STATS
+ bool "Hypervisor call instrumentation"
+ depends on PPC_PSERIES && DEBUG_FS
+ help
+ Adds code to keep track of the number of hypervisor calls made and
+ the amount of time spent in hypervisor callsr. Wall time spent in
+ each call is always calculated, and if available CPU cycles spent
+ are also calculated. A directory named hcall_inst is added at the
+ root of the debugfs filesystem. Within the hcall_inst directory
+ are files that contain CPU specific call statistics.
+
+ This option will add a small amount of overhead to all hypervisor
+ calls.

Include in-kernel hooks for the xmon kernel monitor/debugger.
Unless you are intending to debug the kernel, say N here.

debugger hooks. 'xmon=off' will disable the debugger hooks
if CONFIG_XMON_DEFAULT is set.

Use 'xmon=off' to disable xmon init during runtime.

Say Y here to see progress messages from the boot firmware in text
