Kconfig warnings: (for reference only)
WARNING: unmet direct dependencies detected for DYNAMIC_FTRACE
Depends on [n]: FTRACE [=y] && FUNCTION_TRACER [=y] && HAVE_DYNAMIC_FTRACE
[=n]
Selected by [y]:
- RISCV [=y] && FUNCTION_TRACER [=y]
To avoid that, we should check HAVE_DYNAMIC_FTRACE too:
select DYNAMIC_FTRACE if FUNCTION_TRACER && HAVE_DYNAMIC_FTRACE
That fixes the build error for me. Can you send a v3 with this change?
Thanks,
Alex
