Fedora43更新Linux6.18 kernel Nvidia显卡驱动编译失败

1. 系统信息

出问题的系统版本信息：

• OS:Fedora43
• Kernel: 6.18.0-cachyos2.fc43.x86_64
• Nvidia Driver: 580.105.08

2. 问题发现及处理

2.1 问题定位

更新Fedora43系统后，重启发现无法加载显卡驱动。经过观看启动时的失败信息以及查询后得知，相关日志路径为：

/var/cache/akmods/nvidia/

到相应路径下查看:

cd /var/cache/akmods/nvidia/

ls -hl

发现有一个错误日志文件：

580.105.08-1-for-6.18.0-cachyos2.fc43.x86_64.failed.log

打开日志文件，并进行分析：

vim 580.105.08-1-for-6.18.0-cachyos2.fc43.x86_64.failed.log

最终定位到相应错误：

Build fails:


nvidia-uvm/uvm_va_range_device_p2p.c:363:13: error: too many arguments to function 'get_dev_pagemap'
  363 |             get_dev_pagemap(page_to_pfn(page), NULL);
      |             ^~~~~~~~~~~~~~~

      |                     ^~~~~~~~~~~~~~~

发现驱动get_dev_pagemap() API参数与内核的不匹配导致的。

2.2 问题的解决

经过Google发现网上也有不少人碰到类似的问题，并且发现CachyOS的Github仓库已经提供了对应的patch：

将对应的patch文件下载下来，但是该往哪里打呢。经过分析日志文件和查询发现：

/usr/share/nvidia-kmod-580.105.08/

该目录下有对应的驱动程序压缩代码nvidia-kmod-580.105.08-x86_64.tar.xz，将其复制出来并解压

mkdir ~/kernel

cd ~/kernel

cp /usr/share/nvidia-kmod-580.105.08/nvidia-kmod-580.105.08-x86_64.tar.xz ./

tar -xvf nvidia-kmod-580.105.08-x86_64.tar.xz

rm -f nvidia-kmod-580.105.08-x86_64.tar.xz

并将之前下载的patch文件也放在 ~/kernel/目录下，执行命令

patch -p0 < 0003-nvidia-uvm-Remove-unused-get_devmap_page-parameter.patch

# 压缩
tar caf nvidia-kmod-580.105.08-x86_64.tar.xz ./*

# 将压缩后的文件覆盖掉老的压缩包
sudo mv nvidia-kmod-580.105.08-x86_64.tar.xz /usr/share/nvidia-kmod-580.105.08/

cd /usr/share/nvidia-kmod-580.105.08/

# 修改成root,不然编译时会报找不到文件的错误
sudo chown root:root nvidia-kmod-580.105.08-x86_64.tar.xz

经过以上操作后，重启电脑，会自动进行编译，启动没有报错就代表编译成功。
