- default y
- help
- Selecting this options disables use of the mprofile-kernel ABI for
- kernel tracing. That will cause options such as live patching
- (CONFIG_LIVEPATCH) which depend on CONFIG_DYNAMIC_FTRACE_WITH_REGS to
- be disabled also.
-
- If you have a toolchain which supports mprofile-kernel, then you can
- disable this. Otherwise leave it enabled. If you're not sure, say
- "Y".
