Many aarch64 chips have no aarch32 support for reasons like this
- repiret 6y agoMany? Arm Ltd designed Armv8-a chips fall into three tiers: • Support AArch32 at EL0-EL3 (everywhere) • Support AArch32 at EL0 (user mode) • No AArch32 support The most fielded cores fall into the first category. The newer cores - A76 and it’s contemporaries IIRC - fall into the second category. Only it’s recently disclosed data center cores fall into the third category.
