Applied Micro Mustang 支持kvm

发表于 | 更新于 | 分类于 |

在mustang机器上安装了Centos7，并升级内核到4.1.0-0.rc2

kernel-version

但是dmesg发现并不支持kvm，

[    0.343796] kvm [1]: GICV size 0x2000 not a multiple of page size 0x10000
[    0.343802] kvm [1]: error: no compatible GIC info found
[    0.343909] kvm [1]: error initializing Hyp mode: -6

在这里有相关的patch，https://bugzilla.redhat.com/show_bug.cgi?id=1165290 ，但是打上补丁后虽然能够解决掉kvm的bug，但是又引入了新的问题，ethernet1和eth2识别不了，因为新的内核解析的时候需要增加对应的interrupt reg

patch

按照如下修改后即可，好用的mustang.dts如下：

使用方法如下：

sudo yum install -y dtc
dtc -I dts mustang.dts -O dtb -o /boot/mustang.dtb

随后修改/boot/efi/EFI/centos/grub.cfg中修改第一个entry，添加

devicetree /mustang.dtb

并重启即可~
