From 5b4beba1246ff163415bde41cd76935012b16823 Mon Sep 17 00:00:00 2001 From: Michael Clark Date: Sat, 3 Mar 2018 01:31:13 +1300 Subject: RISC-V Spike Machines RISC-V machines compatble with Spike aka riscv-isa-sim, the RISC-V Instruction Set Simulator. The following machines are implemented: - 'spike_v1.9.1'; HTIF console, config-string, Privileged ISA Version 1.9.1 - 'spike_v1.10'; HTIF console, device-tree, Privileged ISA Version 1.10 Acked-by: Richard Henderson Signed-off-by: Sagar Karandikar Signed-off-by: Michael Clark --- include/hw/riscv/spike.h | 53 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 include/hw/riscv/spike.h (limited to 'include') diff --git a/include/hw/riscv/spike.h b/include/hw/riscv/spike.h new file mode 100644 index 0000000..cb55a14 --- /dev/null +++ b/include/hw/riscv/spike.h @@ -0,0 +1,53 @@ +/* + * Spike machine interface + * + * Copyright (c) 2017 SiFive, Inc. + * + * This program is free software; you can redistribute it and/or modify it + * under the terms and conditions of the GNU General Public License, + * version 2 or later, as published by the Free Software Foundation. + * + * This program is distributed in the hope it will be useful, but WITHOUT + * ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or + * FITNESS FOR A PARTICULAR PURPOSE.
