[PATCH 00/22] m68k: Modernize printing of kernel messages

[Geert Uytterhoeven]

	Hi all,

This patch series modernizes the printing of kernel messages in the m68k
architecture core, which is mainly about converting from printk() to
pr_*().

The trigger for (finally) doing this was the user-visible breakage
caused by commit 4bcc595ccd80decb ("printk: reinstate KERN_CONT for
printing continuation lines").

I had hoped to sent this series much earlier, to be still included in
v4.9, but that didn't happen due to lack of time. Fortunately v4.9 will
be an LTS(I) kernel, so the first three patches (tagged with a "Fixes"
tag) will hopefully make it to v4.9.x later ;-)

Compile-tested with my standard set of configs.
Boot-tested on ARAnyM.

Thanks for your comments!

[PATCH 01/22] m68k/atari: Modernize printing of kernel messages

[Geert Uytterhoeven]

  - Convert from printk() to pr_*(),
  - Add missing continuations, to fix user-visible breakage,
  - Drop useless WARNING prefix,
  - Move trailing spaces to start of continuations.

Fixes: 4bcc595ccd80decb ("printk: reinstate KERN_CONT for printing continuation lines")

[PATCH 06/22] m68k/coldfire: Modernize printing of kernel messages

[Geert Uytterhoeven]

  - Introduce helpers for printing debug messages, incl. dummies for
    validating format strings when debugging is disabled,
  - Convert from printk() to pr_*(),
  - Correct printf()-style format specifiers,
  - Drop superfluous casts,

[PATCH 17/22] m68k/kernel: Modernize printing of kernel messages

[Geert Uytterhoeven]

  - Use pr_err_ratelimited() instead of deprecated printk_ratelimit(),
  - Add dummies for validating format strings when debugging is
    disabled,
  - Convert from printk() to pr_*(),
  - Correct printf()-style format specifiers.

[PATCH 18/22] m68k/mm: kmap - Modernize printing of kernel messages

[Geert Uytterhoeven]

  - Convert from printk() to pr_*(),
  - Add missing continuations,
  - Remove #undef DEBUG.

Note that "#ifdef DEBUG" is sometimes retained because pr_cont() is not
optimized away when debugging is disabled.

This is not equivalent (unless there is a DEBUG macro definition hinding 
in a header file somewhere). Since the changelog doesn't mention 
suppressing any output, perhaps you were deceived by the questionable API, 
as I have been in the past (see 16b9d870a0 and d61c5427f6).

I think it would be good to use pr_debug here instead of #if 0. But that 
will probably break the build... better ignore the #if 0 section for this 
series, until I put together a different patch?

I'd prefer to drop the DEBUG_IRQUSE macro and the debug output it

This file also seems to lack #define DEBUG, so you and Greg might want to 
check this change.

We can use #if 0 here, since the macro can be avoided later...

I think you can avoid the DEBUG_IOP macro entirely, by using

	pr_iop("iop_handle_recv: %*ph\n", IOP_MSG_LEN, msg->message);

Please just remove the DEBUG_IRQS macro and the related output.

These two can be changed to pr_debug() and the #if 0 removed. Since there 
is no DEBUG macro definition here, I believe they will become no_printk() 
and get checked by the compiler.

Thanks.

I think that argues for using printk(KERN_DEBUG ...) and print(KERN_CONT 
...) inside #ifdef DEBUG, which would need no explanation.

If instead you use a combination of pr_debug and pr_cont and #ifdef DEBUG, 
perhaps the explanation should be moved from the commit log to a comment 
in the code?

This is an actual message people want to see in the kernel log, even
when not debugging?

Yes, mac_debug_handler() is unused.

Removing that can be done in a separate patch (this is one of the
patches I'd like
to send upstream ASAP).

Or worse, break at runtime. There's also non-printing code in that block.

you should mention the behavioural change in the commit log.

The NMI isn't easily tiggered, unless you know how. It's solely for 
developers.

Anyway, this is dead code so it makes little difference whether you patch 
it or not. But this hunk will break an NMI debug patch that I've been 
using for ten years or so. Since this code needs a rewrite anyway, you 
might as well avoid the churn IMHO.

But no side-effects, right?

I think we still want this message in, even if DEBUG is
not defined. This code is conditionally compiled in for
hardware debuger processing - and this message should really
come out if this trap case occurs so the user has some idea
that it just tripped. (The text of the message is not perfect,
but that is a separate issue).

Perhaps pr_alert() or pr_crit() would be better?

Greg

Perhaps a better solution than these alternatives would be,

#if defined(DEBUG)
#define pr_debug_cont pr_cont
#else
#define pr_debug_cont no_printk
#endif

But this API is still surprising and ugly. It doesn't work with 
CONFIG_DYNAMIC_DEBUG but that's not so important.

IMO, a far better linux/printk.h would have provided us with these 
definitions:

#define pr_emerg(fmt, ...) \
        printk(KERN_EMERG pr_fmt(fmt), ##__VA_ARGS__)
/* ... */
#define pr_debug(fmt, ...) \
        printk(KERN_DEBUG pr_fmt(fmt), ##__VA_ARGS__)
#define pr_cont(fmt, ...) \
        printk(KERN_CONT fmt, ##__VA_ARGS__)

#if defined(CONFIG_DYNAMIC_DEBUG)
#define pr_debug_cond(fmt, ...) \
        dynamic_pr_debug(fmt, ##__VA_ARGS__)
#define pr_cont_cond(fmt, ...) \
        dynamic_pr_cont(fmt, ##__VA_ARGS__)
#elif defined(DEBUG)
#define pr_debug_cond(fmt, ...) \
        printk(KERN_DEBUG pr_fmt(fmt), ##__VA_ARGS__)
#define pr_cont_cond(fmt, ...) \
        no_printk(KERN_CONT pr_fmt(fmt), ##__VA_ARGS__)
#else
#define pr_debug_cond(fmt, ...) \
        no_printk(KERN_DEBUG pr_fmt(fmt), ##__VA_ARGS__)
#define pr_cont_cond(fmt, ...) \
        no_printk(KERN_CONT pr_fmt(fmt), ##__VA_ARGS__)
#endif

Which have the virtues of symmetry and least surprise.

No, it's not something people want to see - clutters up the screen, and
causes even more interrupt hogging disk IO from syslogd so exacerbates
the problem on slow systems.

But Finn is right in that output is now suppressed instead of given a
particular log level. IMO stating that the message will now only be
generated when the kernel has been compiled for debugging would be
perfectly fine.

Cheers,
