I tested many qemu & linux versions.... in case of qemu, 2.12 3.10 3.12 4.0.0 All versions I tested have same problem....
also I tested many versions of linux ubuntu 18.04 18.10 centos 7 fedora 18 19 rhel Actually it is not only problem of windows rotation, if home launcher refreshed, vram usage is also up... I think it related gl related functions... so I don't sure it is qemu-virt-gpu problem or virt-gpu driver... That is why I already report this problem to android-x86 devel forum and author of virt-gpu drvier... -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1829964 Title: HOST VRAM Leak when performs android-x86 window rotation with Virt-GPU Status in QEMU: Incomplete Bug description: 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. https://www.youtube.com/watch?v=mJIbGZLWF1s&feature=youtu.be (orginal video file : https://drive.google.com/file/d /1lkdTx_8yTbSVjKXlnxnnk96fWe-w6Mxb/view?usp=sharing) 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!!
