Background:
trace-cmd, Function Trace and KernelShark look like very useful tools
for embedded Gentoo. I did manage to find an existing overlay of
unknown quality. [1]

Has anyone on this list used or have any comments on these tools or
equivalents? [2]

Has anyone compared KernelShark to the output of a (physical)
jtag setup?


Curiously,
James
