Subject: Re: [PATCH V4 16/17] riscv: compat: Add COMPAT Kbuild skeletal support
Date: Mon, 31 Jan 2022 04:26:13 -0800 [thread overview]
Message-ID: <YffVZZg9GNcjgVdm@infradead.org> (raw)
In-Reply-To: <20220129121728.1079364-17-guoren@kernel.org>
Given that most rv64 implementations can't run in rv32 mode, what is the
failure mode if someone tries it with the compat mode enabled?
