3	default UNWINDER_PROLOGUE if KALLSYMS
4	help
5	  This determines which method will be used for unwinding kernel stack
6	  traces for panics, oopses, bugs, warnings, perf, /proc/<pid>/stack,
7	  lockdep, and more.

10	bool "Guess unwinder"
11	help
12	  This option enables the "guess" unwinder for unwinding kernel stack
13	  traces.  It scans the stack and reports every kernel text address it
14	  finds.  Some of the addresses it reports may be incorrect.

16	  While this option often produces false positives, it can still be
17	  useful in many cases.

19config UNWINDER_PROLOGUE
20	bool "Prologue unwinder"
21	depends on KALLSYMS
22	help
23	  This option enables the "prologue" unwinder for unwinding kernel stack
24	  traces.  It unwind the stack frame based on prologue code analyze.  Symbol
25	  information is needed, at least the address and length of each function.
26	  Some of the addresses it reports may be incorrect (but better than the
27	  Guess unwinder).
