Hi, This is a re-send of v2 after fixing a trivial conflict with Alistair's riscv-to-apply.next.
No other changes made. All patches acked. Changes from v2: - rebased with Alistair's riscv-to-apply.next - v2 link: https://lore.kernel.org/qemu-riscv/20230926184019.166352-1-dbarb...@ventanamicro.com/ --- API usage examples --- Launch QEMU with "-S" to be able to issue QMP query commands before the machine starts: $ ./build/qemu-system-riscv64 -S -M virt -display none -qmp tcp:localhost:1234,server,wait=off Then use QMP to access the API: $ ./scripts/qmp/qmp-shell localhost:1234 Welcome to the QMP low-level shell!
