>Wouldn't using the 'cpus' property linking to each cpu/hart node work? >Rob Hi, unfortunately, per-CPU property would not work. "hart index" defined per interrupt domain, and different controllers may define it differently. This is from the "4.3 Hart index numbers" section of the interrupts spec found at https://github.com/riscv/riscv-aia Within a given interrupt domain, each of the domain’s harts has a unique index number in the range 0 to 2^14 − 1 (= 16,383).
