Subject: [PULL v2 28/35] target/riscv: Allow users to force enable AIA CSRs in HART
Date: Wed, 16 Feb 2022 16:29:05 +1000 [thread overview]
Message-ID: <20220216062912.319738-29-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20220216062912.319738-1-alistair.francis@opensource.wdc.com>
From: Anup Patel <anup.patel@wdc.com>
We add "x-aia" command-line option for RISC-V HART using which
allows users to force enable CPU AIA CSRs without changing the
interrupt controller available in RISC-V machine.
