@xiaoxiang781216 For example, cxd56xx needs to use up_testset API because the SoC has a restriction to use ldrex and strex.

Yes, in your case not only up_testset, but also atomic_xxx need rewrite for cxd56xx. The issue description is still right, it's better to use atomic api directly, but implement atomic api has different approach:

  1. boolchain's bultin
  2. libs/libc/machine/arc_atomic. for single core
  3. chip special one(e.g. cxd56xx)
