Dear Nitin,

I have tried different measures to increase the load on CPU, but
still the frequency reflects the same value ie. 800Mz.

My question is why this behavior is different w.r.t the one when system boots up with BIOS.

If you have the vendor firmware working, please also attach the information when booted with that.

When I boot with BIOS, I can see that frequency output stays at 2200Mhz.

Do I need to enable some settings under the coreboot code related to
turbo frequency e.t.c ?

Please share your code, so people can take a look.

Please find the lscpu dump as follows:

Architecture:         x86_64
CPU op-mode(s):       32-bit, 64-bit
Byte Order:           Little Endian
Address sizes:        39 bits physical, 48 bits virtual
CPU(s):               5
On-line CPU(s) list:  0,2-4
Off-line CPU(s) list: 1

Why is one CPU off-line?

Thread(s) per core:   1
Core(s) per socket:   4
Socket(s):            1
Vendor ID:            GenuineIntel
CPU family:           6
Model:                95
Model name:           Intel(R) Atom(TM) CPU C3558 @ 2.20GHz
Stepping:             1
CPU MHz:              800.000

No idea, about Atom processors, but on my system there are also two more lines.

CPU max MHz:                     3200,0000
CPU min MHz:                     500,0000

Without knowing your code, people need to stab in the dark. If you cannot share your code, I recommend to get commercial support [1].


Kind regards,

Paul
