I am using the Samsung Performance SDK to try to limit the usage of the high performance CPU cores, so that my application can save more battery. My S21 Ultra with Exynos 2100 has 3 clusters:
1x2.9 GHz Cortex-X1 & 3x2.80 GHz Cortex-A78 & 4x2.2 GHz Cortex-A55
While using the SDK to limit the maximum frequency of the high performance cores, I expect that it has effects on all 4 big cores Cortex 78 and Cortex X1. However, it seems that this only affects the Cortex X1 core.
What can I do to limit the frequency of these Cortex A78 cores?
