- prompt "Choose kernel unwinder"
- default UNWINDER_PROLOGUE if KALLSYMS
- help
- This determines which method will be used for unwinding kernel stack
- traces for panics, oopses, bugs, warnings, perf, /proc/<pid>/stack,
- lockdep, and more.
- config UNWINDER_GUESS
- bool "Guess unwinder"
- help
- This option enables the "guess" unwinder for unwinding kernel stack
- traces. It scans the stack and reports every kernel text address it
- finds. Some of the addresses it reports may be incorrect.
- While this option often produces false positives, it can still be
- useful in many cases.
- config UNWINDER_PROLOGUE
- bool "Prologue unwinder"
- depends on KALLSYMS
- help
- This option enables the "prologue" unwinder for unwinding kernel stack
- traces. It unwind the stack frame based on prologue code analyze. Symbol
- information is needed, at least the address and length of each function.
- Some of the addresses it reports may be incorrect (but better than the
- Guess unwinder).
