std::random_device in libstdc++ reads RDSEED on x86 Linux. On an AMD EPYC 9V45 (Zen 5) CI runner its 32-bit results repeat about 130 times in 65536 draws, so guest_posix_random fails. libc now exports HostEntropy_nid_no_patch, which uses getentropy (rand_s on Windows) and throws when the OS cannot provide entropy. arc4random, arc4random_buf, sceRandomGetRandomNumber, /dev/random and /dev/urandom reads, std::_Random_device and sceKernelUuidCreate use it, and the arc4random and random device TechnicalDebt entries say so.
