core_freq and gpu_freq - is not it the same thing? So core of what?

gpu_freq is a shorthand for specifying core_freq, v3d_freq, h264_freq and isp_freq.

So:

Code:

core_freq=500
gpu_freq=333

means

Code:

core_freq=500
v3d_freq=333
h264_freq=333
isp_freq=333

(an explicit setting like core_freq takes precedence over gpu_freq)

OK, this seems really weird

I have a RPi2 and used the following
arm_freq=1000
gpu_freq=333

I am using bcmstat.sh -c to view things.

After a reboot:
Arm is at 1000 until it finishes a library scan (good)
Core is at 333 until it finishes a library scan (good)
H264 is at 0 until it finishes a library scan (good)

Once library scan is complete
Arm reduces to 600 (good)
Core reduces to 250 (good)
H264 goes up to 250 and stays there (What the heck?)
