However, I see VFIO_DEVICE_QUERY_GFX_PLANE failures which I think should not be there. When the guest didn't define a plane yet I get "No such device" errors instead of a plane_info struct with fields (drm_format, width, height, size) set to zero. I also see "Bad address" errors now and then with no obvious cause. Cursor support isn't working too. I'm testing with "-display egl-headless -spice gl=off,port=...". In that configuration qemu will import the dma-bufs as textures and reads them using ReadPixels for display. qemu branch: https://www.kraxel.org/cgit/qemu/log/?h=work/intel-vgpu The qemu branch has support for both dmabufs and regions. The region- based display code is totaly untested though. cheers, Gerd _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
