Question

问题：

距今已有20年了：
- 我上次写了> 1K的C代码
- 编译了超过1万条源代码行
我目前的Distro对0cf3:e300 Atheros Communications, Inc. WiFi驱动程序的支持（Ubuntu 16.04）非常糟糕：我得到的最好的是8-12Mbps。

我对内核版本优先级的了解：

使用您自己的发行版内核（不可能：太慢了）
使用最新的stable kernel
使用最新的LTS内核

我尝试过的事情：

git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
git checkout -b stable v5.1.2
cp /boot/config-`uname -r` .config
yes '' | make oldconfig
make -j `getconf _NPROCESSORS_ONLN\' deb-pkg LOCALVERSION=-fab

这给了我以下错误：

dpkg-source: error: cannot represent change to vmlinux-gdb.py:
dpkg-source: error:   new version is symlink to /home/fab-user/Documents/Source/linux/scripts/gdb/vmlinux-gdb.py
dpkg-source: error:   old version is nonexistent

在以下完整输出中：

所以我最终做了：

git checkout -b v4.19.38 v4.19.38

可以提供高达10MB / S的速度，而不是我发行版标准内核的12Mbps，效果很好，但是如果要保持WiFi驱动程序的全速运行，我需要每24小时重新启动一次计算机。< / em>

问题：

~~我注定要停留在4.19.38吗？~~
是否有办法使4.19.39-5.12版本永久工作？

Answer 1

只需删除指向vmlinux-pdb.py的{{1}}符号链接，就可以解决我的问题。

因此在内核源代码的根目录中

scripts/gdb/vmlinux-gdb.py

^{另请参见https://www.spinics.net/lists/linux-kbuild/msg18761.html}

Answer 2

您可以简单地从先前的内核和带有-f参数的force it into the new kernel中提取预编译的驱动程序。您只会在journalctl中收到“污点内核”消息，但可以忽略它。

只要ABI保持不变，您就应该可以参加。

Answer 3

尝试从ubuntu git repo进行构建时遇到了这个问题。

scripts/gdb/vmlinux-gdb.py

是先前版本遗留的文件的症状。即使您摆脱了它，也可能会遇到更多错误（接下来我必须删除linux源tarball）。

做

git status

查看许多未跟踪的文件。摆脱它们是目标。

打个mol鼠游戏，而不是一个个地查找文件，更容易

提供所需的一切
删除git无法跟踪的文件

这样做

git clean -r

并在源代码树的顶部执行此操作。

然后尝试编译

Linux最新的稳定编译：无法表示对vmlinux-gdb.py的更改：
