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
