From 7c824b43ba0303e139ccba117f10f5c39e157ed1 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 3 Sep 2024 17:22:17 +0100 Subject: [PATCH] hw/arm/sbsa-ref: Use two-stage SMMU MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that our SMMU model supports enabling both stages of translation at once, we can enable this in the sbsa-ref board. Existing guest code that only programs stage 1 and doesn't care about stage 2 should continue to run with the same behaviour, but guests that do want to do nested SMMU configurations can now do so.
