Now that we have virtio-gpu Vulkan support, let's add a test for it. Currently this is using images build by buildroot: https://lists.buildroot.org/pipermail/buildroot/2024-December/768196.html Signed-off-by: Alex Bennée <alex.bennee@linaro.org> --- v2 - use decorator for has_cmd(zstd) - un-handled->unhandled - drop extra - from --snapshot - drop unneeded virtualization=on - only show 1s of each scene - fix long lines v3 - move set_machine/require_accelerator to top of test - use uncompress utility function - remove extra ()'s from ASSETS v4 - split misc fixups into earlier commits - don't swallow leading newlines before class - fixup commit message --- tests/functional/test_aarch64_virt.py | 74 ++++++++++++++++++++++++++- 1 file changed, 72 insertions(+), 2 deletions(-)
