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).
