From aeac4c590a0cca478f8a58b6489c702f5970721b Mon Sep 17 00:00:00 2001 From: Pierrick Bouvier Date: Sun, 24 Nov 2024 16:50:09 -0800 Subject: [PATCH] tests/functional/aarch64: add tests for FEAT_RME This boot an OP-TEE environment, and launch a nested guest VM inside it using the Realms feature. We do it for virt and sbsa-ref platforms.
