安装固件时可能丢失固件

Question

虽然安装了固件(在Debianbook蠕虫上)，但我还是会丢失固件消息。

我遵循这个解决方案，可能丢失的固件/lib/固件/i 915/*用于模块i 915

所以我安装了firmware-linux，firmware-linux-nonfree和firmware-misc-nonfree，它们确实丢失了。但是在安装它们之后，消息就不会消失。

我在这里错过了什么？

Answer 1

固件仍然丢失，因为您安装的包的当前版本不提供您的内核正在寻找的固件。例如，您的内核需要skl_guc_69.0.3.bin，但是固件包的版本只能达到skl_guc_62.0.0.bin。

这意味着对于当前的Book蠕虫内核来说，Book蠕虫中的固件包太老了；这有时会在Debian的下一个版本的开发过程中发生。

这里最好的方法是在firmware-misc-nonfree上提交一个bug，要求更新，包括丢失的文件。考虑一下“交易”的这一部分，因为您正在运行Debian测试--您正在帮助Debian解决下一个版本中的问题(感谢您这样做了！)跑

reportbug firmware-misc-nonfree

跟着提示走。(有人有已经做过了，谢谢Artem S. Tashkinov找到了这个。)

在固件包更新之前，您还可以使用从上游存储库安装缺失的固件：

mkdir firmware
cd firmware
wget -r -nd -e robots=no -A '*.bin' --accept-regex '/plain/' https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915/
sudo mv *.bin /lib/firmware/i915/
sudo update-initramfs -c -k all

还请注意，“缺失固件”消息涵盖了加载在系统上的内核模块可以使用的所有可能文件；它们不限于系统实际需要的文件。如果您的系统运行良好，那么您可以忽略它们。如果您需要的固件确实丢失了，您将在内核日志(sudo dmesg)中看到“i 915/skl_guc_69.0.3.bin因错误-2而失败”形式的错误。

一个bug报告已经存在：https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1860784.html

要解决这个问题，您可以：git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git和sudo cp所需的文件。
