From: lixianglai <lixianglai@xxxxxxxxxxx> Hello, Everyone: This patch series adds libvirt support for loongarch.Although the bios path and name has not been officially integrated into qemu and we think there are still many shortcomings, we try to push a version of patch to the community according to the opinions of the community, hoping to listen to everyone's opinions. Anyway we have a version of libvirt that supports loongarch. You can also get libvirt's patch from the link below: https://gitlab.com/lixianglai/libvirt branch: loongarch Since the patch associated with loongarch has not yet been submitted to the virt-manager community, we are providing a temporary patch with loongarch for the time being patch's virt-manager, the open source work of virt-manager adding loongarch will be followed up later or synchronized with the open source libvirt. You can get the virt-manager code with loongarch patch from the link below: https://github.com/loongson/virt-manager branch: loongarch loongarch's virtual machine bios is not yet available in qemu, so you can get it from the following link https://github.com/loongson/Firmware/tree/main/LoongArchVirtMachine (Note: You should clone the repository using git instead of downloading the file via wget or you'll get xml) We named the bios edk2-loongarch64-code.fd, edk2-loongarch64-vars.fd is used to store pflash images of non-volatile variables.After installing qemu-system-loongarch64, you need to manually copy these two files to the /user/share/qemu directory. Since there is no fedora operating system that supports the loongarch architecture, you can find an iso that supports loongarch at the link below for testing purposes: https://github.com/fedora-remix-loongarch/releases-info Well, if you have completed the above steps I think you can now install loongarch virtual machine, you can install it through the virt-manager graphical interface, or install it through vrit-install, here is an example of installing it using virt-install: virt-install \ --virt-type=qemu \ --name loongarch-test \ --memory 4096 \ --vcpus=4 \ --arch=loongarch64 \ --boot cdrom \ --disk device=cdrom,bus=scsi,path=/root/livecd-fedora-mate-4.loongarch64.iso \ --disk path=/var/lib/libvirt/images/debian12-loongarch64.qcow2,size=10,format=qcow2,bus=scsi \ --network network=default \ --osinfo archlinux \ --feature acpi=true \ --video=virtio \ --graphics=vnc,listen=0.0.0.0 lixianglai (5): Add loongarch cpu support Add loongarch cpu model and vendor info Config some capabilities for loongarch virt machine Implement the method of getting host info for loongarch Add bios path for loongarch po/POTFILES | 1 + src/conf/schemas/basictypes.rng | 1 + src/cpu/cpu.c | 2 + src/cpu/cpu.h | 2 + src/cpu/cpu_loongarch.c | 742 +++++++++++++++++++++++++++++ src/cpu/cpu_loongarch.h | 25 + src/cpu/cpu_loongarch_data.h | 37 ++ src/cpu/meson.build | 1 + src/cpu_map/index.xml | 5 + src/cpu_map/loongarch_la464.xml | 6 + src/cpu_map/loongarch_vendors.xml | 3 + src/cpu_map/meson.build | 2 + src/qemu/qemu.conf.in | 3 +- src/qemu/qemu_capabilities.c | 6 + src/qemu/qemu_conf.c | 3 +- src/qemu/qemu_domain.c | 32 ++ src/qemu/qemu_domain.h | 1 + src/qemu/qemu_domain_address.c | 55 +++ src/qemu/qemu_validate.c | 2 +- src/qemu/test_libvirtd_qemu.aug.in | 1 + src/util/virarch.c | 4 + src/util/virarch.h | 4 + src/util/virhostcpu.c | 4 +- src/util/virsysinfo.c | 5 +- 24 files changed, 940 insertions(+), 7 deletions(-) create mode 100644 src/cpu/cpu_loongarch.c create mode 100644 src/cpu/cpu_loongarch.h create mode 100644 src/cpu/cpu_loongarch_data.h create mode 100644 src/cpu_map/loongarch_la464.xml create mode 100644 src/cpu_map/loongarch_vendors.xml -- 2.27.0 _______________________________________________ Devel mailing list -- devel@xxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxx
