The 5.10 kernel release brought support for the Pinephone A64 processor’s true hardware random number generator under the sun8i-ce module. However, even after I load the module I am not getting a working /dev/hwrng.
The patch adding this support to the 5.10 kernel provides a new kernel option that must be activated before building the kernel:
Is this option selected in Mobian's kernel build? If not, could I request that it be activated?

Code:
