Message-ID: <155849670573.15101.16014286335079778238.malone@gac.canonical.com> (raw)
In-Reply-To: 155849647074.15430.13880026935625975661.malonedeb@wampee.canonical.com

Here are qemu options I used...

-machine type=q35,accel=kvm -cpu host --enable-kvm \
-smp cpus=4,cores=4,threads=1 -m 4096 \
-drive file=ctb0319.qcow2,format=qcow2,if=virtio,aio=threads \
-device virtio-vga,virgl=on \
-device qemu-xhci,id=xhci -device usb-mouse,bus=xhci.0 -device usb-kbd,bus=xhci.0 \
-soundhw hda -display sdl,gl=on -netdev user,id=qemunet0,hostfwd=tcp::4000-:7000,hostfwd=tcp::5555-:5555,hostfwd=tcp::4012-:7012,hostfwd=tcp::4013-:7013 -device virtio-net,netdev=qemunet0 -boot menu=on

** Description changed:

  I will report something strange thing about host VRAM leakage after
  anroid-x86 window rotation when it runs with virt-gpu(+ virgl-renderer)
  
  Please watching below video link.

  I don't sure what is the problem...
  
  Here are my tested history
  --------------------------------------------------------------------------------------------------
  Install android-x86 on I7 desktop PCs with intel UHD GPU  - No leak.
  Install android-x86 on I7 desktop PCs with NVIDIA GTX GPU series - No leak.
  Install android-x86 on guest machine emulated skylake cpu with QEMU(+virt-gpu, virgl-renderer) - Leak
  (HOST CPU - I5, INTEL UHD GPU)
  Install android-x86 on guest machine emulated skylake cpu with QEMU(+virt-gpu, virgl-renderer) - Leak
  (HOST CPU - I7, NVIDIA GTX GPU)
  
  COMMON:
  In case of NVIDIA GPU : check vram using nvidia-smi
  In case of intel UHD GPU : check shared-vram using free cmd
  
  We checked guest android-x86 system down when vram is full after performing many rotation
  -------------------------------------------------------------------------------------------
  
  Is it virt-gpu driver's problem?
  
  I hope someone can help me...
  
  Thanks in advance!!
