As of today, all RISC-V machines (except virt) are still using
memory_region_init_ram()
to initilize the sysytem RAM, which can't possibly handle vhost-user, and can't
work as expected with '-numa node,memdev' options.
Change to 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.
Changes in v2:
- split RAM into low and high regions using aliases to machine->ram
- rename mc->default_ram_id to "microchip.icicle.kit.ram"
- opentitan: add RAM size check
- opentitan: assign mc->default_ram_size
- sifive_e: add RAM size check
- sifive_e: assign mc->default_ram_size
Bin Meng (6):
hw/riscv: microchip_pfsoc: Use MachineState::ram and
MachineClass::default_ram_id
hw/riscv: opentitan: Use MachineState::ram and
MachineClass::default_ram_id
hw/riscv: shakti_c: Use MachineState::ram and
MachineClass::default_ram_id
hw/riscv: sifive_e: Use MachineState::ram and
MachineClass::default_ram_id
hw/riscv: sifive_u: Use MachineState::ram and
MachineClass::default_ram_id
hw/riscv: spike: Use MachineState::ram and
MachineClass::default_ram_id
