Subject: [PATCH v2 19/19] target/riscv/cpu: move priv spec functions to tcg-cpu.c
Date: Wed, 6 Sep 2023 06:16:46 -0300 [thread overview]
Message-ID: <20230906091647.1667171-20-dbarboza@ventanamicro.com> (raw)
In-Reply-To: <20230906091647.1667171-1-dbarboza@ventanamicro.com>
Priv spec validation is TCG specific. Move it to the TCG accel class.
