From 71c356a07fbbf1530cfc87960e975f93bc9007e8 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Tue, 22 Jul 2025 09:46:03 -0700 Subject: [PATCH] Use getrandom syscall on riscv32/riscv64 linux Minimum kernel needed on RISCV is fairly new (4.15+) so we are sure to have getrandom syscall, on glibc there is mimimal ABI kernel to denote it but musl does not have any other way to indicate it, so add it as a condition here to choose getrandom backend for rv32/rv64 on linux when using musl.
