仅在某些处理器供应商上运行某些 ansible 任务

我想为一组服务器配置 IOMMU 设置。执行此操作需要在 Intel 服务器上对 grub 配置进行如下更改：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=on iommu=pt"

与 AMD 服务器类似：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=on iommu=pt"

我尝试了以下方法：

---
- name: Configure GRUB for IOMMU based on CPU manufacturer
  hosts: your_target_hosts
  become: yes  # Necessary for permissions to edit GRUB config and update GRUB
  tasks:
    - name: Set GRUB options for Intel systems
      ansible.builtin.lineinfile:
        path: /etc/default/grub
        regexp: '^GRUB_CMDLINE_LINUX_DEFAULT='
        line: 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=on iommu=pt"'
        backrefs: yes
      when: ansible_processor_vendor == 'GenuineIntel'
      notify: update-grub

    - name: Set GRUB options for AMD systems
      ansible.builtin.lineinfile:
        path: /etc/default/grub
        regexp: '^GRUB_CMDLINE_LINUX_DEFAULT='
        line: 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=on iommu=pt"'
        backrefs: yes
      when: ansible_processor_vendor == 'AuthenticAMD'
      notify: update-grub

  handlers:
    - name: update-grub
      ansible.builtin.command:
        cmd: update-grub

但是，当我运行剧本时，Ansible 说ansible_processor_vendor未定义。

我该如何实际构建这个剧本来适当地完成对每个供应商的配置更改？

这似乎有效！我不得不使用when: ansible_processor[1] == 'GenuineIntel'：

---
- name: Configure GRUB for IOMMU based on CPU manufacturer
  hosts: your_target_hosts
  become: yes  # Necessary for permissions to edit GRUB config and update GRUB
  tasks:
    - name: Set GRUB options for Intel systems
      ansible.builtin.lineinfile:
        path: /etc/default/grub
        regexp: '^GRUB_CMDLINE_LINUX_DEFAULT='
        line: 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=on iommu=pt"'
        backrefs: yes
      when: ansible_processor[1] == 'GenuineIntel'
      notify: update-grub

    - name: Set GRUB options for AMD systems
      ansible.builtin.lineinfile:
        path: /etc/default/grub
        regexp: '^GRUB_CMDLINE_LINUX_DEFAULT='
        line: 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=on iommu=pt"'
        backrefs: yes
      when: ansible_processor[1] == 'AuthenticAMD'
      notify: update-grub

  handlers:
    - name: update-grub
      ansible.builtin.command:
        cmd: update-grub
