Subject: can we enable perf during the kernel initialization?

Message-ID: <4E1501D1.4030805@gmail.com> (raw)
Hello,
Does the current kernel allow us to enable perf during the kernel
initialization? perf is initialized in a very early stage, but I cannot
find any kernel parameters that can enable perf. Has anyone tried to use
perf to profile the kernel during its initialization?
Thanks,
Da
