解决方案

:white_check_mark: 方法一：检查并创建 systemd 服务软链接（推荐）

参考 OpenUBMC 社区已有案例 #3321 的解决方案：

“直接拉取同步 PR_235 分支即可自动加载，帖子中操作失败是因为 /root/workspace/manifest/build/product/BMC/openUBMC/rootfs/etc/systemd/system/multi-user.target.wants/ 下直接新建 devmon.service，但实际这里新增的应该是 /root/workspace/manifest/build/product/BMC/openUBMC/rootfs/etc/systemd/system/devmon.service 的软链接。”

操作步骤如下：

# 1. 确认 devmon.service 是否存在
ls /etc/systemd/system/devmon.service

# 2. 若不存在，请确认源文件是否存在（通常由 Conan 或构建流程生成）
find /opt -name "devmon.service" 2>/dev/null
# 示例路径可能为：/opt/bmc/devmon/devmon.service

# 3. 如果找到源文件，则创建软链接到 multi-user.target.wants
sudo ln -s /opt/bmc/devmon/devmon.service /etc/systemd/system/multi-user.target.wants/devmon.service

# 4. 重新加载 systemd 配置并尝试启动服务
sudo systemctl daemon-reexec
sudo systemctl daemon-reload
sudo systemctl start devmon.service

# 5. 检查服务状态
systemctl status devmon.service

:warning: 注意：路径可能因构建方式不同而异，请结合 openUBMC 构建输出确定准确路径。

:white_check_mark: 方法二：验证是否已将 devmon 添加到 manifest 构建配置

确保 devmon 已正确集成到产品构建系统中。检查以下文件：

  1. manifest/build/subsys/rc/hardware.yml 或其他 yml 文件

    - conan: "devmon/1.2.23@openUBMC.release/stable"

  2. manifest/build/product/BMC/openUBMC/manifest.yml

    dependencies:
  - devmon/1.2.23@openUBMC.release/stable

若未添加，请补充后使用 bingo build 重新构建固件。

:white_check_mark: 方法三：确认 devmon 服务是否被 Conan 包管理器正确安装

运行以下命令检查 devmon 是否被 Conan 正常部署：

# 查询 Conan 是否安装了 devmon 包
conan list "devmon*" -r=openubmc_dev

# 查看安装路径
conan info devmon/1.2.23@openUBMC.release/stable --paths

确保相关二进制文件和服务描述文件已部署到目标路径。

devmon 组件加载异常问题分析与解决方案

问题概述

devmon 组件在系统启动过程中未能正常加载，导致多个系统组件（如 chassis、firmware_mgmt、power_mgmt 等）无法获取其提供的设备监控服务。核心错误日志为：

fetch devmon objects failed, err=org.freedesktop.DBus.Error.ServiceUnknown: The name bmc.kepler.devmon was not provided by any .service files

该错误表明 D-Bus 系统无法找到 bmc.kepler.devmon 服务的 .service 配置文件，因此无法启动该服务。

根本原因分析

根据上下文信息和类似问题的社区讨论，devmon 组件未能加载的根本原因是其对应的 systemd 服务文件未被正确部署或注册。

具体表现为：

  • 虽然已通过 Git 克隆获取了 devmon 源码（git@gitcode.com:openUBMC/devmon.git），但缺少将其作为系统服务安装的步骤。
  • 系统依赖 .service 文件来声明如何启动 D-Bus 服务。若该文件缺失或未软链接至 systemd 加载目录，则即使程序存在也无法自动启动。
  • 从日志可以看出，多个核心模块（如 chassis、bios、thermal_mgmt 等）都在尝试从 devmon 获取设备信息，说明 devmon 是南向设备管理的关键组件。

补充说明

:small_blue_diamond: devmon 组件的功能定位

根据搜索结果，devmon 是一个设备监控系统，主要功能包括：

  • 监控和管理各种硬件设备（如 PCIe 设备、扩展卡）
  • 提供 D-Bus 接口：bmc.dev.devmon
  • 支持设备重新发现（DiscoverDevices()）和列表查询（GetDeviceList()）
  • 作为 component_drivers 驱动框架的基础服务，加载 .so 驱动文件

:small_blue_diamond: 为什么这么多组件都依赖 devmon？

日志显示 chassis、pcie_device、general_hardware 等数十个模块均试图从 devmon 获取对象，说明它是：

  • 设备拓扑发现的核心代理
  • D-Bus 资源协作机制的中枢
  • 南向设备驱动注册与加载的统一入口

验证是否修复成功

执行以下命令验证 devmon 是否正常运行：

# 查看 D-Bus 服务是否可见
busctl --user list | grep bmc.kepler.devmon

# 查看 devmon 资源树（如果有提供此接口）
busctl --user tree bmc.kepler.devmon

# 再次查看 app.log 是否仍有 ServiceUnknown 报错
grep "devmon" /var/log/app.log | grep "ServiceUnknown"

若不再出现 ServiceUnknown 错误，并且 systemctl status devmon.service 显示 active (running)，则表示问题已解决。

component_drivers和libmcpp是什么版本？你升级的BMC包是自己构建的还是在哪个链接获取的？journalctl看下有没有devmon相关的日志？是否有 检查并创建 systemd 服务软链接？

1.**与libmcpp的版本有关，**重新拉libmcpp组件就可以了。下面是目前环境中三个组件的版本

  • conan: “libmcpp/1.2.64@openubmc/stable”

  • conan: “component_drivers/1.2.74@openubmc/stable”

  • conan: “devmon/1.2.23@openubmc/stable”

2.BMC包是自己构建的连接AtomGit | GitCode - 全球开发者的开源社区,开源代码托管平台

3.journalctl下devmon的日志没有查看，我看了devmon组件中的文档发现可能与libmcpp组件的版本有关，更新libmcpp组件就可以正常加载了。

4.检查过，软连接都是正常的。

devmon组件加载成功，没有识别到添加的传感器芯片驱动，看日志分析应该是在解析CSR文件时没找芯片的配置信息，这个芯片的配置信息放在了vpd/vendor/Huawei/Server/Kunpeng/openUBMC/root.sr中，应该配置在devmon组件中的.sr文件吗？devmon组件中的.sr文件都在./tests/tests_data/csr/目录中
