Subject: [PATCH v4 06/22] target/riscv: Add AIA cpu feature
Date: Tue, 26 Oct 2021 12:12:11 +0530 [thread overview]
Message-ID: <20211026064227.2014502-7-anup.patel@wdc.com> (raw)
In-Reply-To: <20211026064227.2014502-1-anup.patel@wdc.com>
We define a CPU feature for AIA CSR support in RISC-V CPUs which
can be set by machine/device emulation. The RISC-V CSR emulation
will also check this feature for emulating AIA CSRs.
