无法让ixgbevf在当前的Ubuntu AMI上构建

Question

AWS文档声明您需要构建源以获得为Ubuntu AMI启用的增强联网:http: //docs.aws.amazon.com/AWSEC2/latest/UserGuide/sriov-networking.html#enhanced-networking-ubuntu

美国西部2 xenial,ami-835b4efa目前的AMI失败了: Building module: cleaning build area.... cd src/; make BUILD_KERNEL=4.4.0-1020-aws....(bad exit status: 2) ERROR (dkms apport): binary package for ixgbevf: 3.1.2 not found Error! Bad return status for module build on kernel: 4.4.0-1020-aws (x86_64) Consult /var/lib/dkms/ixgbevf/3.1.2/build/make.log for more information.

Answer 1

这是AWS内核命名对话的问题.

查看日志文件:

  ^

它抱怨UTS_UBUNTU_RELEASE_ABI

Ubuntu内核文档声明内核版本的第4个数字是ABI,https://wiki.ubuntu.com/KernelTeam/BuildSystem/ABI,但当前的AWS内核版本是: Linux ip-10-16-89-81 4.4.0-1020-aws

查看/usr/src/ixgbevf/src/kcompat.h中的违规代码:

#if UTS_UBUNTU_RELEASE_ABI > 255
#error UTS_UBUNTU_RELEASE_ABI is too large...
#endif /* UTS_UBUNTU_RELEASE_ABI > 255 */

人们可以看到这不会飞,1020> 255

这是一个脚本,我用它作为自定义包postinst来解决这个问题.如果您从这里获得源tgz,也可以直接从shell运行此脚本https://sourceforge.net/projects/e1000/files/ixgbevf%20stable/3.1.2/ in~ /

%> cat src/deb/control/postinst
#!/bin/bash -e
[ "${DEBUG}" ] && set -x
cd ~/ixgbevf
ver="3.1.2"
tar -xzf ~/ixgbevf-${ver}.tar.gz
rm -rf /usr/src/ixgbevf-${ver}
mv ixgbevf-${ver} /usr/src/
touch /usr/src/ixgbevf-${ver}/dkms.conf
kernelver=$(uname -r)
cat <<-EOT > /usr/src/ixgbevf-${ver}/dkms.conf

dkms build -m ixgbevf -v ${ver}
dkms install -m ixgbevf --all
dkms autoinstall -m ixgbevf
update-initramfs -c -k all
modinfo ixgbevf

我已经通知了AWS这个,但是在此期间,希望这将为其他人节省WTF时刻'这不是我今天想要做的'

编辑:

得到了AWS的跟进 - 他们正在向英特尔驱动程序支持团队推动这一过程.这是驱动程序的检查,假设ABI <255已损坏,而不是AWS内核版本控制方案.

Answer 2

此问题的解决方法是通过运行以下命令禁用此检查:

$ sudo sed -i '/#if UTS_UBUNTU_RELEASE_ABI > 255/c\/*#if UTS_UBUNTU_RELEASE_ABI > 255' /usr/src/ixgbevf-2.16.4/src/kcompat.h
