Camera Power Optimization

A few options are available to reduce the power consumption of camera use cases.
Exercise caution when applying these BIOS settings since they can have an undesired influence on other use cases by effectively restraining the CPU clock frequency management.
BIOS Settings
In the BIOS system, navigate to the following menu:
Device Manager -> System Setup -> CPU Configuration -> CPU Power Management
Set both Intel Turbo Boost Technology and C-States to “Disable”
Set Power Limit 1 between 6 and 9 watts
Also see the Active Fan-Sink thermal solution to increase heat dissipation.
Set IPU clock
In addition, it is possible to limit the maximum IPU clock within an available range of 200 MHz – 600 MHz in 50 MHz steps by using this command format:
echo 300 > /sys/kernel/debug/0000\:00\:03.0/buttress/psys_force_freq

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
