Recently I need to compile a special Android Kernel version，whicH includes a special driver named as Virtio-Video。 It's part of Virtio Standards and can be used for Virtualization.In android,it will be part of Cuttlefish/Trout.View repo details please check this link:https://android.googlesource.com/kernel/manifest/+/refs/heads/trout-android12-5.10;view the instructions please check this:https://source.android.com/docs/setup/build/building-kernels
And I have followed the offical instructions:
repo init -u https://android.googlesource.com/kernel/manifest -b trout-android12-5.10
because I need the Virtio-Video driver,so I used the command below to build:
BUILD_CONFIG=common-modules/virtual-device/build.config.virtual_device.x86_64 build/build.sh
But I get some errors like these:

And when I check the commit log,I found another command:
BUILD_CONFIG=common-modules/virtual-device/build.config.trout.coqos build/build.sh
this command excuted OK and I got the output virtio-vedio.ko but it's ARM arch.But I need x86 arch.Can someone tell me how can I fix the compile errors?
