Hi The patch looks good to me, but I tried to use egl-headless for the first time, and I get a weird crash on virgl init: (gdb) bt #0 0x00007fffd8cd935f in rawmemchr () at /lib64/libc.so.6 #1 0x00007fffd8cc1832 in _IO_str_init_static_internal () at /lib64/libc.so.6 #2 0x00007fffd8cb37e7 in vsscanf () at /lib64/libc.so.6 #3 0x00007ffff6e818a6 in vsscanf () at /lib64/libasan.so.3 #4 0x00007ffff6e819d3 in sscanf () at /lib64/libasan.so.3 #5 0x00007ffff6bfe239 in vrender_get_glsl_version (glsl_version=0x60e00001f2b8) at vrend_renderer.c:6026 #6 0x00007ffff6bfe239 in vrend_create_context (id=id@entry=0, nlen=nlen@entry=0, debug_name=debug_name@entry=0x0) at vrend_renderer.c:4033 #7 0x00007ffff6c04f2f in vrend_renderer_context_create_internal (handle=0, nlen=0, debug_name=0x0) at vrend_decode.c:1066 #8 0x00007ffff6bf72a3 in vrend_renderer_init (cbs=<optimized out>, flags=0) at vrend_renderer.c:3874 #9 0x0000555556b52cc1 in virtio_gpu_virgl_init (g=0x633000008d10) at /home/elmarco/src/qemu/hw/display/virtio-gpu-3d.c:623
This doesn't happen when I use virgl/spice (gl=on obviously) I guess you don't know what's going on, and I will look further later, I just thought it was worth to report in case you had an idea.
