Subject: [PULL 33/33] hw/riscv: spike: Use MachineState::ram and MachineClass::default_ram_id
Date: Fri, 22 Oct 2021 23:38:12 +1000 [thread overview]
Message-ID: <20211022133812.3972903-34-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20211022133812.3972903-1-alistair.francis@opensource.wdc.com>
From: Bin Meng <bmeng.cn@gmail.com>
Using memory_region_init_ram(), which can't possibly handle vhost-user,
and can't work as expected with '-numa node,memdev' options.
Use MachineState::ram instead of manually initializing RAM memory
region, as well as by providing MachineClass::default_ram_id to
opt in to memdev scheme.
