VM Test Bench (VMTB) is a tool for testing virtualization (SR-IOV) supported by the xe driver. It allows to enable and provision VFs (Virtual Functions) and facilitates manipulation of VMs (Virtual Machines) running virtual GPUs. Initially only basic test scenarios are provided: - enable VFs, pass it to VMs and boot guest OS - submit basic workloads on a guest with virtualized GPU - exercise VF driver probe and remove Proposed location for the new tool is the root IGT directory: igt-gpu-tools/vmtb but some other options can be also considered, for example: tools/vmtb tests/vmtb v2: - improve device detection function: instead of parsing lspci output with regex, iterate over sysfs driver directory to get bound devices' BDFs (Marcin) - remove obsolete fixtures and other unused code (Marcin) v3: - integrate VMTB with IGT meson build/install system (Kamil) - move the tool from IGT's root to tools/vmtb subdir (Kamil) - split VMTB core implementation, tests, resources and meson config into separate patches (Kamil) -
