Hey, people. It seems there is hardware random number generator support in the ARM 8.5 instruction set. As far as I can tell, it has not been included in Linux kernels yet. Any ideas on how to get that ball rolling? lore.kernel.org/linux-arm-kern

@trode specific to Graviton 4 instances? If so and you can share the use case, I have some people at Annapurna I can talk to.

@jonschwenn seems like graviton 3+ from what I understand. Use case is golang libraries supporting Hashicorp vault gaining hardware RNG

@trode I believe gv3 uses the 8.4 ISA. But I can look into it on Monday.

@jonschwenn Ah. We would use graviton 4 to gain that capability. It's totally a workday problem. thx!
