Benjamin Valentin 39b8cdf760 sys/random: default to musl LCG ... In [0] the paper concludes with > The Knuth LCG is the most efficient general purpose generator that > provides decent statistical quality. > It is simple and lean enough to run on very constrained devices. So let's select `prng_musl_lcg` to be the default PRNG instead of `prng_tinymt32`. This gives a good chunk of memory on e.g. `samr21-xpro`: prng_tinymt32 ------------- text data bss dec hex filename 26452 136 2824 29412 72e4 tests/rng/bin/samr21-xpro/tests_rng.elf prng_musl_lcg ------------- text data bss dec hex filename 26208 136 2808 29152 71e0 tests/rng/bin/samr21-xpro/tests_rng.elf [0] https://sci-hub.se/10.1145/3453159		2021-11-11 19:59:26 +01:00
