Subject: Re: [intel-pstate driver regression] processor frequency very high
 even if in idle

Hi,

I am using Intel-PState-Driver here with v4.6-rc1 and Intel-SandyBridge-CPU.

Here are my turbostat results attached.

$ cd $BUILD_DIR
$ LC_ALL=C make -C tools/ turbostat

$ sudo ./turbostat -i 1 --msr=0x199 --debug --out
/tmp/turbostat-i-1-msr-0x199-debug.txt

Will try <https://patchwork.kernel.org/patch/8702071/>.

Please see attached files.

Regards,
- Sedat -
