Cannot open opengl games in 7.1-rc2

[Philip Z]

Hi Android-x86 experts,
I used to be able to open some opengl games with 7.1-rc1, but I can't open them successfully any more with 7.1-rc2 (game exits right after starting). I suspect if it's because we use SwiftShader as the software renderer. Am I able to switch to other software renderer to see if it fixes the issue? Let me know if you have any suggestions or need more details.

Thanks!

Philip

What device and GPU did you use?
What games did you test?

It's possible. But you need to rebuild the source
to enable the old software renderer by mesa.

Hi Chih-Wei,

I used qemu kvm with no GPU. 

I tested 王者荣耀 and 穿越火线.

I actually compiled the source by myself. So, if you can point me to where I can enable the old software renderer, that will be great.

Thanks,

Philip

The same problem is with VMware. If you download the android x64 with 3D acceleration, the game "Defens Zone 3" starts with a black screen, and there is a sound and when you press the ESC, you exit the game. If you download android with the key "nomodeset" then this game starts fine. I also compiled android x64 from the MESA 17.2.2. In this assembly, the game starts normally when using 3D acceleration. In my opinion, the problem is in MESA 17.1.x.

Hi fguy,
How did you compile x64 with Mesa 17.2.2? Any guide to follow? Thanks!

How did you compile x64 with Mesa 17.2.2? Any guide to follow? Thanks!

 

I managed to download Mesa 17.2.2 when it was active in the repository of this project. A small patch fixes the build error. This version has a problem with 3d ATI / AMD adapters and so the authors returned to 17.1.10 for android 7.1.2.

I see. Could you tell me which version or the date of your Android x86 source code is? What is the small patch fix that fixes the build error?

Thanks,

Philip

Thanks, fguy!
I checked my external/mesa repo and it included the Oct 5 merge fix by Chih-wei. I didn't see anything about 17.2. Is the changeset removed?
Thanks,

you need to ask this question Chih-Wei Huang

In 7.1-rc2 QEMU supports two mode.
With -vga std it uses the software renderer.
With -vga virtio it uses the virtual GPU virgl
to provide much better 3D performance.
You can read the qemu-android script
to understand how to enable virgl exactly.

If your QEMU is built with virglrenderer
you should try virgl first.

I downloaded the apps from qq.com.
I tested them with two QEMU modes,
as well as Intel GPU (i965, Skylake).
The app crashed in all cases with the log:

10-19 16:52:01.287 3821 3847 W libc : pthread_create
sched_setscheduler call failed: Operation not permitted
10-19 16:52:01.369 3821 3862 W art : Long monitor contention

10-19 16:52:01.553 1405 1465 I ActivityManager: Process

It looks like not an issue of the renderer.
Maybe it's updated and broken in android-x86.
If you have kept the old apk,
you may try it in 7.1-rc2.
Or, if you install the same apk to 7.1-rc1,
does it still work?

You need to revert commit 2c04b2e and 658c992
in device/generic/common to go back to the old
mesa swrast. (maybe more, I didn't verify)

The VMware (vmwgfx) issue is entirely different than
the issue of QEMU. Please don't mix them up.

I also tested the "Defense Zone 3 HD" on QEMU.
It works well with virgl and software renderer.

After more testing, I surprisingly found it's
an issue of the new houdini 7.1.
The 64-bit 7.1-rc2 equips with new houdini libs
that seems to be incompatible with the two apps.
If I using the old houdini 6, it just works.
(with both virgl and swiftshader)
I didn't really play it (don't know how to play).
I just see the welcome screen so I guess it's OK.

The 32-bit 7.1-rc2 still uses old houdini 6.
You can just try it.

They are the first apps I found which can't
work with newer houdini. Interesting...
