choice 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). endchoice
