* [OpenRISC] [PATCH 2/3] trace: refactor TRACE_IRQFLAGS_SUPPORT in Kconfig
@ 2021-07-31  5:22   ` Masahiro Yamada
  0 siblings, 0 replies; 47+ messages in thread
From: Masahiro Yamada @ 2021-07-31  5:22 UTC (permalink / raw)
  To: openrisc

Make architectures select TRACE_IRQFLAGS_SUPPORT instead of
having many defines.

* [PATCH 3/3] trace: remove redundant dependency from IRQSOFF_TRACER

IRQSOFF_TRACE is already guarded by a stronger condition,
TRACING_SUPPORT.

'depends on TRACE_IRQFLAGS_SUPPORT' is redundant.

I'm fine with the other two patches, but this one concerns me. I'm not
sure TRACING_SUPPORT really needs to depend on TRACE_IRQFLAGS_SUPPORT.
When tracing was first introduced, the main use case was the irqsoff
tracer. Today, with function graph tracing and events being introduced,
it's one of the minor use cases of tracing support.

I believe the only thing that requires the TRACE_IRQFLAGS_SUPPORT is
the irqsoff tracer (and friends), so if anything, we should remove that
dependency from TRACING_SUPPORT, not here.

OK.
The first two are more trivial, so please pick up
1/3 and 2/3, then drop this one.



BTW, I personally prefer HAVE_* to *_SUPPORT.

Maybe renaming as follows makes the code more consistent.

   STACKTRACE_SUPPORT      -> HAVE_STACKTRACE
   TRACE_IRQFLAGS_SUPPORT  -> HAVE_TRACE_IRQFLAGS



Documentation/kbuild/kconfig-language.rst says
HAVE_* style is the recommended way.



It is a common idiom to implement a feature/functionality that are
relevant for some architectures but not all.
The recommended way to do so is to use a config variable named HAVE_*
that is defined in a common Kconfig file and selected by the relevant
architectures.
An example is the generic IOMAP functionality.

We would in lib/Kconfig see::

  # Generic IOMAP is used to ...
  config HAVE_GENERIC_IOMAP

  config GENERIC_IOMAP
       depends on HAVE_GENERIC_IOMAP && FOO
