[Qemu-devel] [Bug 1829964] [NEW] HOST VRAM Leak when performs android-x86 window rotation with Virt-GPU

[Eunseok Choi]

Public bug reported:

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!!

[Eunseok Choi]

To Thomas Huth,

This is not android problem, qemu or virt-gpu  problem,.
-------------------- our test log --------------------------------------
Running android-x86 on I7 bare metal desktop PCs with intel UHD GPU - No leak.
Running android-x86 on QEMU(+virt-gpu, virgl-renderer) - Leak
------------------------------------------------------------------------

Also in case of a guest linux, it also have leak after windows manager
rotation.

[Thomas Huth]

Ok, sorry, got that wrong - we sometimes get bug reports about the
android emulator (which is a fork of QEMU) here, and at a first glance,
your bug report looked like one of these misguided bug tickets, too.

Anyway, please provide some more information: Which version of QEMU are
you using? Which operating system are you running in QEMU?

[Qemu-devel] [Bug 1829964] Re: HOST VRAM Leak when performs android-x86 window rotation with Virt-GPU

[Eunseok Choi]

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...
