|
|
This determines which method will be used for unwinding kernel stack
|
|
traces for panics, oopses, bugs, warnings, perf, /proc/<pid>/stack,
|
|
lockdep, and more.

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.

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).
