Hi, This is Wonsang Ryu. I'm developer working in South Korea. Do you have forum or community for any developer? I want share my issues with other developers. I have some question about QEMU.
I am porting an embedded OS for emulator to QEMU. My environment is Host OS : Ubuntu 14.04 64bit Guest OS : x86 Embedded Linux OS (like as open embedded) Guest UI Options : using SDL2, virglrenderer Basic running is ok. I have a problem about screen resolution. Recommended resolution of my guest OS is 1920x1080. If a QEMU window size is 1920x1080, it is clear. But, if I change smaller of a QEMU window size, it does not display clearly.(ex: 1280x720) In this case, QEMU windows size in host is 1280x720, and guest screen resolution is 1920x1080. For example, it is similar with same resolution support of different monitor size. I think, it need to enable the MultiSampling(or anti-aliasing) of OpenGL. Does not support MultiSampleing in QEMU yet? Or, is it related with virglrenderer? I found, QEMU does not use MULTISAMPLING option in "sdl2-gl.c". And, "nr_samples" is always zero in "virtio-gpu-3d.c". I think, it need to apply multisampling to texture received from virglrenderer. How can I enable a multisampling option in QEMU? I want to hold the resolution of the guest OS and scale the QEMU windows in the host OS. When scale QEMU windows, I want display is more clear even though small. Is it possible? Please help me. Thanks.
