Linux 5.18 is bringing many random/RNG improvements thanks to the work of kernel developer Jason Donenfeld. One of the changes though that had to be backed out during the merge window was trying to get /dev/random and /dev/urandom to behave exactly the same. While reverted for now with the 5.18 code, Donenfeld has prepared a change that should get it into good shape for major architectures with the next kernel cycle...

As a Linux kernel change for benefiting AMD CPUs going back to Zen 1 and for matching behavior Intel has had in place since the Core 2 times, AMD submitted a patch for having the Linux kernel use the MWAIT instruction instead of HALT for when the system isn't using the CPU idle driver either for C-states being disabled by the BIOS or the driver not part of the kernel build. In turn this can lead to around a 21% improvement in exit latency on affected systems...
