Get latest qemu source code -2. Build qemu `mkdir build && cd build && ../configure && ninja` -3. Check if following command runs without errors and show sdl qemu window - ``` - sudo ./qemu-system-x86_64 \ - -object memory-backend-memfd,id=mem1,size=512M \ - -machine memory-backend=mem1 \ - -display sdl \ - -device virtio-vga,blob=on - - ``` -4. Then try to build with modules enabled `mkdir build && cd build && ../configure --enable-modules && ninja` -5. Try to do step 3 again -Additional information: -I tried to debug this bug, and found that problem is with function `virtio_gpu_have_udmabuf`: when qemu is build without modules this function is from `hw/display/virtio-gpu-udmabuf.c` (which is correct), but when qemu compiled with modules this function comes from `stubs/virtio-gpu-udmabuf.c` and when `hw-display-virtio-gpu.so` is loaded, `virtio_gpu_have_udmabuf` is not replaced, and remains function from stub (which always return 0) and command fails. - -I think I will submit patch that fix it tomorrow |
