Subject: [PATCH v2 27/71] target/arm: Add SMIDR_EL1, SMPRI_EL1, SMPRIMAP_EL2
Date: Tue,  7 Jun 2022 13:32:22 -0700	[thread overview]
Message-ID: <20220607203306.657998-28-richard.henderson@linaro.org> (raw)
In-Reply-To: <20220607203306.657998-1-richard.henderson@linaro.org>

Implement the streaming mode identification register, and the
two streaming priority registers.  For QEMU, they are all RES0.
