[PATCH 00/31] CPUFreq: Implement light weight ->target(): for 3.13
From: Viresh Kumar
Date: Mon Aug 12 2013 - 13:49:33 EST
Currently prototype of cpufreq_drivers target routines is:
int target(struct cpufreq_policy *policy, unsigned int target_freq,
unsigned int relation);
And most of the drivers call cpufreq_frequency_table_target() to get a valid
index of their frequency table which is closest to the target_freq. And they
don't use target_freq and relation after it.
So, it makes sense to just do this work in cpufreq core before calling
cpufreq_frequency_table_target() and simply pass index instead. But this can be
done only with drivers which expose their frequency table with cpufreq core. For
others we need to stick with the old prototype of target() until those drivers
are converted to expose frequency tables.
So, in order not to break those special drivers first patch renames ->target() to
->target_old() and the following patches will define the new prototype and
convert existing drivers one by one.
There are 12 drivers after this patchset which still use the heavy weight
version, i.e. target_old() and 39 drivers have adopted this new approach.
Once those 12 drivers are also moved to use .target(), .target_old() will be
removed completely.
This is part 3 of my generic cpufreq cleanup stuff.. First two are posted here
and this one is rebased of them:
1: cpufreq: Introduce cpufreq_table_validate_and_show()
https://lkml.org/lkml/2013/8/8/263
2: cpufreq: define generic routines for cpufreq drivers
https://lkml.org/lkml/2013/8/10/48
After this patchset this is the diffstat for 107 patches:
