因此, 使用 nodemask 来记录具有相同命中记录的节点, 巨大的页面分配可能会回退到这些节点. 并删除__GFP_THISNODE, 因为它不允许回退. 如果 nodemask 为空 (没有设置节点), 这意味着只有一个节点的历史记录最多, nodemask 方法实际上类似于 `__GFP_THISNODE`.

通常, 当操作系统内核启动时, 它会发现可用内存并愉快地设置自己以使用该内存. 但是, UEFI 规范的 2.9 版添加了不可接受内存 (unaccepted memory) 的概念; 使用此机制时, 系统 (通常是虚拟化来宾) 将启动, 其内存处于不可接受状态. 在明确接受内存之前, 该系统将无法使用提供的内存. 在此类系统上, 引导加载程序通常会预先接受足够的内存以允许来宾内核引导; 该内核在使用之前必须负责接受其余部分.

| 加速开启 TDX/SEV-SNP 后虚拟机的启动. | SEV-SNP 和英特尔 TDX 等安全访客环境可以通过加密、反向映射表等方式保护其内存内容免受主机和其他访客的影响. 但是, 设置该保护需要一些时间, 这会大大减慢启动过程. 显式接受步骤允许操作系统随时间推移内存初始化. 如果仅在需要时以块形式接受内存, 则系统将更快地启动到运行状态. 来自 Kirill Shutemov 的添加未接受内存支持的补丁利用了这一点, 将内存的接受推迟到需要时才接受. |
| 显式接受有助于保护安全的来宾免受恶意虚拟机监控程序的侵害 | 这些虚拟机监控程序可能会尝试在后台使用来宾的内存玩游戏. 如果虚拟机监控程序尝试将新页面潜入来宾的地址空间, 则来宾将不接受该新内存, 并且尝试访问它将生成错误. |
每个供应商的安全环境都有自己的管理验收过程的方法, 因此实现验收的一些代码必须特定于一个子体系结构. Shutemov 的补丁增加了对英特尔 TDX 的支持, 但对 AMD 的 SEV-SNP 的支持来自 Tom Lendacky 的单独补丁集.
为解析 ascii 跟踪输出的流行方法提供一种更高效、更强大的替代方法, 以便从中提取有用的信息. 为了避免所有这些的开销和复杂性, 这个补丁集提供了一个直接到脚本的解释器路径来做同样的事情, 但以一种更规则化的方式, 它利用了跟踪基础结构提供的所有事件元信息, 例如为此目的设计的 "格式文件" 中包含的事件 / 字段信息. 它允许将通用脚本语言的全部功能应用于跟踪流, 以进行非琐碎的分析, 并突然提供了大量有用的工具和模块库(例如, 用于 Perl 的 CPAN), 以应用于创建新的、有趣的跟踪应用程序的问题. 当前只实现了一个 Perl 接口, 但其目的是使添加对其他语言(如 Python、Ruby 等)的支持相对容易——他们所需要做的就是以 Perl 实现为例, 提供自己的 trace_scripting_ops 实现和支持函数.
