内核配置更改不会粘在 yocto zeus 上，但同样的方法适用于 hardknott答案

【问题标题】：Kernel configuration change does not stick on yocto zeus but same method works for hardknott内核配置更改不会粘在 yocto zeus 上，但同样的方法适用于 hardknott
【发布时间】：2022-01-25 11:24:04
【问题描述】：

我想要更改两个内核配置，以便在 Linux 内核中打开 IPU 驱动程序。

内核版本是5.4.70， yocto版本是宙斯，

以下是我尝试过的一些方法，我已经使用bitbake -c menuconfig virtual/kernel打开了配置

更改我想更改的设置，然后bitbake -c diffconfig virtual/kernel

它给了我一个 fragment.cfg 文件，我只是将它复制到我的 bbappend 然后 SCR_URI 它。

它在 hardknot 版本上的工作方式相同，但在 Zeus 上不一样。

我还将整个内核的配置保存到 .config 文件中，然后将其名称更改为 defconfig 并使用 do_append 复制该文件，它将文件复制到内核目录中，但它也没有改变任何内容。

我的更改会一直生效，直到我对完整的映像进行 bitbake，或者直到我 -c clean virtual/kernel。

下面是片段文件，知道我要更改的内容

稍后编辑：

这是我在 Zeus build 和 Hardknott build 中发现的区别，

在 Hardknott 中，hardknot_ide/build/tmp/work-shared/imx8mp-var-dart/kernel-source/ 有一个名为 .kernel-meta 的隐藏文件夹，它包含我所做的所有更改，例如，如果我的配置文件或 defconfig 文件中有重复的任何参数登录它。

这是该文件夹中的日志文件的一个示例。

但是没有像这样的文件夹或文件被放入 Zeus 构建中，我已经清理它然后重新构建它，但仍然没有出现这个文件夹。

【解决方案1】：

好吧，Zeus 和 Hardknott 之间发生了一些变化，所以这可能与此有关，无论如何，可能会发生几件事：

片段本身没有被应用
Kconf 不喜欢该内核版本的配置并丢弃它
用户错误

让我们首先检查是否正在应用片段，假设您在 bitbake 可以找到它的某个位置获得了 fragment.cfg 文件，并且您已将其添加到 SRC_URI_append="file://fragment.cfg"

之后，运行：

$ bitbake virtual/kernel -c cleansstate && bitbake virtual/kernel -c kernel_configme

应该清理你拥有的一切，然后重新创建内核配置。

完成后，您需要查看 merge_config_build.log，这是所有片段合并到最终 .config 时的日志文件。

它应该在某处： /tmp/work-shared//kernel-source/.kernel-meta/cfg/merge_config_build.log

打开该文件并检查 fragment.cfg 是否在要合并的文件列表中：

应该是这样的（这是一个不同的内核版本，但应该是相似的）：

$ cat tmp/work-shared/qemuarm64/kernel-source/.kernel-meta/cfg/merge_config_build.log 
Using .kernel-meta/configs/v5.15/ktypes/base/base.cfg as base
Merging .kernel-meta/configs/v5.15/standard/ktypes/standard/standard.cfg
Merging .kernel-meta/configs/v5.15/standard/features/kprobes/kprobes.cfg
Merging .kernel-meta/configs/v5.15/standard/features/uprobe/uprobe.cfg
Merging .kernel-meta/configs/v5.15/standard/features/utrace/utrace.cfg

如果您的片段文件列在那里，那么 bitbake 正在完成它的工作并且您的配方看起来不错，这意味着由于某种原因 Kconf 不喜欢您的新 CONFIGS（可能缺少依赖项或者它们不兼容/对你的内核版本）。

还值得检查一下 merge_config_build.log 的其余部分，它可能包含说明 Kconf 特别不喜欢您的配置的行：

Value requested for CONFIG_EARLY_PRINTK_DBGP not in final .config
Requested value:  CONFIG_EARLY_PRINTK_DBGP=y
Actual value:     

Value requested for CONFIG_TTY_PRINTK not in final .config
Requested value:  CONFIG_TTY_PRINTK=y
Actual value:

最后，没有必要在任何附加文件中复制 .config，如果你只是将其重命名为 defconfig，并将其添加到 SRC_URI，bitbake 应该能够将其拾取并将其用作基础（它将应用片段最重要的），你会在最开始的合并日志中看到它作为defconfig：

$ cat tmp/work-shared/qemuarm64/kernel-source/.kernel-meta/cfg/merge_config_build.log 
    Using <path>/defconfig as base

更新：

从更新的问题中获得更多详细信息后，很明显这是从 NXP 构建 Zeus 分支，而不是直接从 Yocto 项目构建，这会产生一些分歧。

但是，以下内容已针对 NXP 的流程进行了定制，并经过测试可以正常工作：

1.- 创建一个配置片段，例如my-fragment.cfg 并将其放在 linux-imx 目录中：

├── recipes-kernel                                                                                    
│   ├── linux                                                                                    
│   │   ├── linux-imx                           
│   │   │   └── my-fragment.cfg                                                                     
│   │   ├── linux-imx_5.4.bb                                                                     
│   │   └── linux-imx-headers_5.4.bb

2.- 在内核配方内的SRC_URI 中列出此类文件，以便通过 bitbake 将其拉入 WORKDIR：

SRC_URI_append = " file://my-fragment.cfg"

3.- 在 DELTA_KERNEL_DEFCONFIG 变量中列出相同的文件，使其与 NXP 的流程一起使用：

DELTA_KERNEL_DEFCONFIG_prepend = "my-fragment.cfg "

示例文件：

$ cat linux-imx/my-fragment.cfg
CONFIG_COMPILE_TEST=y

# Configure the kernel to look at the final .config file used
$ bitbake virtual/kernel -c configure

# Check if the required configs were merged into the kernel config
$ grep COMPILE_TEST tmp/work/imx8mpevk-poky-linux/linux-imx/5.4-r0/build/.config
CONFIG_COMPILE_TEST=y

【讨论】：

这一定是旧版本Yocto中使用的旧方法，我试过这个，但首先kernel_configme不起作用，因为它不是Zeus中认可的命令。其次，工作共享文件夹中没有merge_config_build.log。
请检查我的问题的编辑部分。
现在查看您编辑的帖子，我可以看到您使用的机器是 imx8mp-var-dart，我假设您是从 NXP 的来源构建的，可能在这里：source.codeaurora.org/external/imx/meta-imx/tree/meta-bsp/… 看起来像那个任务NXP 使用的基本上会丢弃您对内核配置所做的任何更改（这是我所指的自定义类型）。听起来您可以将所需的额外配置放在 .config 文件中并设置：DELTA_KERNEL_DEFCONFIG 而不是 SRC_URI
是的，他们甚至对较新版本的配方发表了评论： # 重要提示：此任务有效地禁用内核配置片段 # 因为在 do_kernel_configme 中应用的配置片段已被替换。 source.codeaurora.org/external/imx/meta-imx/tree/meta-bsp/…
连这个方法都行不通，我试过了。
