Subject: [PATCH 05/10] target/arm: GPT_Secure is reserved without FEAT_SEL2
Date: Thu, 25 Sep 2025 17:11:29 -0700 [thread overview]
Message-ID: <20250926001134.295547-6-richard.henderson@linaro.org> (raw)
In-Reply-To: <20250926001134.295547-1-richard.henderson@linaro.org>
For GPT_Secure, if SEL2 is not enabled, raise a GPCF_Walk exception.
