Re: [PATCH 0/2] Fix per-policy boost behavior

Hi Sibi,

Thanks for pointing this issue out.

However, I can't clearly see how the existing code fails.

cpufreq_frequency_table_cpuinfo() checks cpufreq_boost_enabled(),
and that should be already set in cpufreq_boost_trigger_state() before
calling cpufreq_boost_set_sw(), so presumably cpufreq_boost_set_sw()
is supposed to work as expected.

Can you explain this a bit further?

Cheers,
Jie
