[PATCH for-11.0 0/2] Build fixes for minimal microvm

Posted by Ani Sinha 2 weeks, 3 days ago

Some build fixes for building a minmal qemu for microvm 

cc -m64 @qemu-system-x86_64.rsp
ld: libqemu-x86_64-softmmu.a.p/target_i386_kvm_kvm.c.o: in function `hyperv_init_vcpu':
target/i386/kvm/kvm.c:1757:(.text+0x5d83): undefined reference to `hyperv_is_synic_enabled'
ld: libqemu-x86_64-softmmu.a.p/hw_i386_x86-common.c.o: in function `x86_bios_rom_reload':
hw/i386/x86-common.c:1104:(.text+0x240d): undefined reference to `x86_firmware_configure'
collect2: error: ld returned 1 exit status

The build is done with the devices file:

CONFIG_PCI_DEVICES=n
CONFIG_MICROVM=y
CONFIG_VIRTIO_BLK=y
CONFIG_VIRTIO_SERIAL=y
CONFIG_VIRTIO_INPUT=y
CONFIG_VIRTIO_INPUT_HOST=y
CONFIG_VHOST_USER_INPUT=y
CONFIG_VIRTIO_NET=y
CONFIG_VIRTIO_SCSI=y
CONFIG_VIRTIO_RNG=y
CONFIG_VIRTIO_CRYPTO=y
CONFIG_VIRTIO_BALLOON=y
CONFIG_VIRTIO_GPU=y
CONFIG_VHOST_USER_GPU=y

and with these confiure options:

../../configure ${common_configure_opts} \
              --without-default-features \
              --target-list=x86_64-softmmu --enable-kvm --disable-tcg \
              --enable-pixman --enable-vnc \
              --enable-virtfs \
              --enable-linux-aio --enable-linux-io-uring \
              --enable-numa \
              --enable-attr \
              --enable-coroutine-pool \
              --audio-drv-list="" \
              --without-default-devices \
              --with-devices-x86_64=microvm \
              --enable-vhost-kernel --enable-vhost-net \
              --enable-vhost-vdpa \
              --enable-vhost-user --enable-vhost-user-blk-server \
