Subject: [PATCH 1/2] acpi-cpufreq: make the freq_table store the same freq value
Date: Fri, 28 Nov 2014 10:43:38 +0800 [thread overview]
Message-ID: <1417142619-14548-2-git-send-email-wangweidong1@huawei.com> (raw)
In-Reply-To: <1417142619-14548-1-git-send-email-wangweidong1@huawei.com>
As the initialized freq_tables maybe different from the p-states
values, so the array index is different as well.
Although in this case:
p-states value: [2400 2400 2000 ...], while the freq_tables:
[2400 2000 ... CPUFREQ_TABLE_END]. After setted the freqs 2000,
the perf->state is 3 while the freqs_table's index should be 2.
So when call the get_cur_freq_on_cpu, the freqs value we get
is 2400.
So, make the freq_table store the same value as well.
