[PATCH 00/35] cpufreq: Introduce cpufreq_table_validate_and_show()

[PATCH 00/35] cpufreq: Introduce cpufreq_table_validate_and_show()

[Viresh Kumar]

This is actually part of a bigger patchset which will change declaration of
cpufreq_driver->target() to include index instead of target_freq and relation
and hence cpufreq drivers wouldn't require to cpufreq_frequency_table_target()
anymore.

Almost every cpufreq driver is required to validate its frequency table with:
cpufreq_frequency_table_cpuinfo() and then expose it to cpufreq core with:
cpufreq_frequency_table_get_attr().

This patch creates another helper routine cpufreq_table_validate_and_show() that
will do both these steps in a single call and will return 0 for success, error
otherwise.

This also fixes potential bugs in cpufreq drivers where people have called
cpufreq_frequency_table_get_attr() before calling
cpufreq_frequency_table_cpuinfo(), as the later may fail.

[Viresh Kumar]

Lets use cpufreq_table_validate_and_show() instead of calling
cpufreq_frequency_table_cpuinfo() and cpufreq_frequency_table_get_attr().

Assuming the new function simply does what the two removed lines do,
this looks fine to me.

This doesn't seem to be mentioned in the commit description. I assume
this is simply dead/useless code removal?

Its useless and the correct routine isn't called at all :) .. I will add that
additional patch and send it to you and will get this change out of this

Subject: [PATCH 01/36] cpufreq: Add new helper
 cpufreq_table_validate_and_show()

Almost every cpufreq driver is required to validate its frequency table with:
cpufreq_frequency_table_cpuinfo() and then expose it to cpufreq core with:
cpufreq_frequency_table_get_attr().

This patch creates another helper routine cpufreq_table_validate_and_show() that
will do both these steps in a single call and will return 0 for success, error
otherwise.

This also fixes potential bugs in cpufreq drivers where people have called
cpufreq_frequency_table_get_attr() before calling
cpufreq_frequency_table_cpuinfo(), as the later may fail.

Lets use cpufreq_table_validate_and_show() instead of calling
cpufreq_frequency_table_cpuinfo() and cpufreq_frequency_table_get_attr().

I'd be happy to test, but those changes cause build failures on top of
next-20130809. Which other patches do I need to apply first?

None.. You applied all three attached patches? I have given it a try
on my side now and it worked without any issues..

Just pushed out a branch for you as well:

Well, I don't see any issues running this, although the cpufreq sysfs
files seem to have disappeared on Tegra, even without your changes, so
I'm not sure how to really verify cpufreq.

Did the sysfs files go away, or do I need to investigate why/when the
disappeared?

It wasn't enabled by default in your defconfig... So enable it first with
your menuconfig.

I'm not copied on the patch that introduces function
cpufreq_table_validate_and_show().  So if it does the right/equivalent
thing, for cpufreq-cpu0 and imx6q-cpufreq:

You better check it :)

https://lkml.org/lkml/2013/8/8/266

I wasn't probably following the right way for sending mails as I was expecting
people to look at these patches over list..

In the next series with 44 patch I tried to fix this issue. And so cc'd people
on cover-letter and the important patch they must check.

It's in defconfig OK; I think the driver simply isn't initializing since
some of the clocks it requests don't exist. I'll have our clock driver
author look into it. In the meantime, I assume that your change is
likely fine.

I wasn't' talking about your driver but cpufreq_stats.. That is disabled
by default with your defconfig.
