simics - 如何在 Simics QSP 客户端核心中启动旧版 BIOS (coreboot)？

Question

我正在使用 Simics 6.0.83(公开发布预览版)，其目标是基于 qsp-client-core.simics 定义的，并尝试将 coreboot 二进制文件作为旧版 BIOS 启动。

我正在尝试的配置:

# In order to run this, the QSP-x86 (2096), QSP-CPU (8112) and
# QSP-Clear-Linux (4094) packages should be installed.

decl {
! Script that runs the Quick Start Platform (QSP) with a client processor core.

 params from "%simics%/targets/qsp-x86/qsp-clear-linux.simics"
  default cpu_comp_class = "x86-coffee-lake"
  default num_cores = 4
  default enable_efi = FALSE
  default bios_image = "/home/debian/dasharo/coreboot/build/coreboot.rom"
}

run-command-file "%simics%/targets/qsp-x86/qsp-clear-linux.simics"

当尝试从 simics CLI 运行run-command-file 时，我得到:

[board.mb.cpu0.core[0][0] unimpl] Warning: Cache flush without writeback (will not warn again for this CPU).

如何在 Simics 中尝试 coreboot？

Answer 1

我很好奇，因此基于 https://doc.coreboot.org/tutorial/part1.html 使用 coreinfo 作为有效负载克隆、构建和启动了 coreboot

也许你可以看看我的 defconfig，如下
