As the initialized freq_tables maybe different from the p-states values, so the array index is different as well. 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, fix the problem with the correct tables. Signed-off-by: Wang Weidong <wangweidong1@huawei.com> --- drivers/cpufreq/acpi-cpufreq.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)
