ARM is the only architecture providing sched_clock.h and setup_sched_clock().
Implement sched_clock() for use by other architectures.

Can you rework this to not use #ifdefs within the function? They make it
annoying to read the code.
Instead maybe have a local setup_sched_clock() function that sets the
mult value for the !CONFIG_HAVE_SETUP_SCHED_CLOCK case?

Also, can you try to condense the number of #ifndef
CONFIG_HAVE_SETUP_SCHED_CLOCK checks to one, and consolidate the needed
functions all in that one conditional?

Thanks for your comments. I'll rework the patch and resubmit.
I've just noticed that I have a bigger problem. read_sched_clock() returns
u32, not u64. This means that in a rate of, say, 100MHz it will wrap around
after a little more than 40 seconds. Would it make sense to put ARM's 32 bin
sched_clock extension code (arch/arm/kernel/sched_clock.c) is a common place
(maybe drivers/clocksource), and use that? There seems to be nothing ARM
specific in this code, after all.

Yea, working out an actual generic sched_clock implementation is
something I'd like to see done.
Though I'd really rather we not toss yet another chunk of infrastructure
in the drivers/clocksource directory. Instead we should probably have a
kernel/time/sched_clock.c.
Then its just the issue of tying that and the clocksource code together
so you just register existing capable clocksources with a SCHED_CLOCK
flag or via a different registration hook.
I don't think it will be an easy job, but if you want to give it a shot,
I'd be quite interested in reviewing the patches!
thanks

Although I'd very much like to contribute in this area, I'm afraid I don't
have time for this now. My problem is much narrower in scope, though, and I
think it can be solved without a generic sched_clock implementation at first
step. All I want is to use a 32 bit counter for sched_clock. The code enabling
this is currently only available for ARM (arch/arm/kernel/sched_clock.c).
Should this part of the code move to kernel/time/sched_clock.c?

Also note that there are two conflicting changes to this area
pending. It seems one in soc-next arm tree will prevail.
Please take a look...

Now that generic sched_clock implementation is available to all architectures
(38ff87f77 "sched_clock: Make ARM's sched_clock generic for all architectures"
in the timers/core branch of the tip tree) this patch is not needed anymore.
Thanks for the head up.
