ping > 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/lixianglai/virt-manager > branch: loongarch > > loongarch's virtual machine bios is not yet available in qemu,So you need to compile > loongarch UEFI yourself, > you can refer to the following link to compile UEFI: > https://github.com/tianocore/edk2-platforms/blob/master/Platform/Loongson... > Here we provide compiled UEFI for ease of testing,you can get it from the following link: > https://github.com/lixianglai/LoongarchVirtFirmware > (Note: You should clone the repository using git instead of downloading the file via wget > or you'll get xml) > We named the bios QEMU_EFI.fd, QEMU_VARS.fd is used to store pflash images of non-volatile > variables. > After installing qemu-system-loongarch64,You can install the loongarch bios by executing > the script > install-loongarch-virt-firmware.sh > > 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 > The operating system provided above may have minor problems of one kind or another, > but you can also find out from the following link that openEuler's operating system > supports loongarch: > https://muug.ca/mirror/openeuler/openEuler-22.03-LTS/ISO/loongarch64/ > > 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 \ > --video=virtio \ > --graphics=vnc,listen=0.0.0.0 > > CHANGES > V2->V3: > 1.Delete redundant header files in cpu_loongarch.c > 2.Fixed code formatting issues > 3.Modify the commit message of [PATCH 2/4] > 4.Remove useless test cases for loongarch, > Rebuild loongarch's test case based on the latest code. > > V1->V2: > 1.Modify the link addresses of virtu-manager and firmeware in the cover > letter. Please obtain the code and firmware from the latest link > address. > 2.Rename the bios name. Delete the loongarch bios name from libvirt > and use the json file to obtain the bios path. > 3.Refer to riscv64 to simplify the implementation of loongarch cpu > driver.And fix some code style errors. > 4.Delete unnecessary or redundant device enablement.Such as USB NEC. > 5.Add some test cases for loongarch. > > Xianglai Li (4): > Add loongarch cpu support > Support for loongarch64 in the QEMU driver > Implement the method of getting host info for loongarch > Add test script for loongarch > > src/conf/schemas/basictypes.rng | 1 + > src/cpu/cpu.c | 2 + > src/cpu/cpu_loongarch.c | 58 + > src/cpu/cpu_loongarch.h | 25 + > src/cpu/meson.build | 1 + > src/qemu/qemu_capabilities.c | 16 +- > src/qemu/qemu_command.c | 7 +- > src/qemu/qemu_domain.c | 40 +- > src/qemu/qemu_domain.h | 1 + > src/qemu/qemu_validate.c | 1 + > src/util/virarch.c | 13 +- > src/util/virarch.h | 13 +- > src/util/virhostcpu.c | 7 +- > src/util/virsysinfo.c | 3 +- > .../qemu_8.2.0-tcg-virt.loongarch64.xml | 163 + > .../qemu_8.2.0-virt.loongarch64.xml | 167 + > tests/domaincapstest.c | 4 +- > .../caps_8.2.0_loongarch64.replies | 30121 ++++++++++++++++ > .../caps_8.2.0_loongarch64.xml | 175 + > .../qemucaps2xmloutdata/caps.loongarch64.xml | 28 + > ...o-type-loongarch64.loongarch64-latest.args | 34 + > ...eo-type-loongarch64.loongarch64-latest.xml | 45 + > .../default-video-type-loongarch64.xml | 18 + > ...-models.loongarch64-latest.abi-update.args | 44 + > ...t-models.loongarch64-latest.abi-update.xml | 79 + > ...irt-default-models.loongarch64-latest.args | 44 + > ...virt-default-models.loongarch64-latest.xml | 79 + > .../loongarch64-virt-default-models.xml | 24 + > ...ch64-virt-graphics.loongarch64-latest.args | 56 + > ...rch64-virt-graphics.loongarch64-latest.xml | 116 + > .../loongarch64-virt-graphics.xml | 48 + > ...ch64-virt-headless.loongarch64-latest.args | 52 + > ...rch64-virt-headless.loongarch64-latest.xml | 102 + > .../loongarch64-virt-headless.xml | 42 + > ...minimal.loongarch64-latest.abi-update.args | 31 + > ...-minimal.loongarch64-latest.abi-update.xml | 26 + > ...rch64-virt-minimal.loongarch64-latest.args | 31 + > ...arch64-virt-minimal.loongarch64-latest.xml | 26 + > .../loongarch64-virt-minimal.xml | 15 + > tests/qemuxmlconftest.c | 7 + > tests/testutilshostcpus.h | 10 + > 41 files changed, 31749 insertions(+), 26 deletions(-) > create mode 100644 src/cpu/cpu_loongarch.c > create mode 100644 src/cpu/cpu_loongarch.h > create mode 100644 tests/domaincapsdata/qemu_8.2.0-tcg-virt.loongarch64.xml > create mode 100644 tests/domaincapsdata/qemu_8.2.0-virt.loongarch64.xml > create mode 100644 tests/qemucapabilitiesdata/caps_8.2.0_loongarch64.replies > create mode 100644 tests/qemucapabilitiesdata/caps_8.2.0_loongarch64.xml > create mode 100644 tests/qemucaps2xmloutdata/caps.loongarch64.xml > create mode 100644 > tests/qemuxmlconfdata/default-video-type-loongarch64.loongarch64-latest.args > create mode 100644 > tests/qemuxmlconfdata/default-video-type-loongarch64.loongarch64-latest.xml > create mode 100644 tests/qemuxmlconfdata/default-video-type-loongarch64.xml > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-default-models.loongarch64-latest.abi-update.args > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-default-models.loongarch64-latest.abi-update.xml > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-default-models.loongarch64-latest.args > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-default-models.loongarch64-latest.xml > create mode 100644 tests/qemuxmlconfdata/loongarch64-virt-default-models.xml > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-graphics.loongarch64-latest.args > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-graphics.loongarch64-latest.xml > create mode 100644 tests/qemuxmlconfdata/loongarch64-virt-graphics.xml > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-headless.loongarch64-latest.args > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-headless.loongarch64-latest.xml > create mode 100644 tests/qemuxmlconfdata/loongarch64-virt-headless.xml > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-minimal.loongarch64-latest.abi-update.args > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-minimal.loongarch64-latest.abi-update.xml > create mode 100644 > tests/qemuxmlconfdata/loongarch64-virt-minimal.loongarch64-latest.args > create mode 100644 tests/qemuxmlconfdata/loongarch64-virt-minimal.loongarch64-latest.xml > create mode 100644 tests/qemuxmlconfdata/loongarch64-virt-minimal.xml _______________________________________________ Devel mailing list -- devel@xxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxx
