Dolphin Intel processor

[Arteetego]

I have a Lenovo yoga book android version, it has an intel processor but I cant run any game... What should I do? I upload the log file here : https://mega.nz/#!ZdowjYAT!QJq5uuiw_-R5hwxDf3C4pUh7mLc8wXIaVA-7_VAW-7M
Thank you

This is a x86/64 processor, most Android devices are ARM, I'm not sure about the level of compatibility of Dolphin on Android with this kind of CPU. Other thing is the GPU, it's an Intel HD Graphics, the drivers aren't good even on Windows, on Android they should be worse, another probable reason for you not to run.
Anyway your CPU (Atom X5 Z8550) is weak for emulation (slower than most recent Snapdragon devices). If the compatibity with your kind of CPU is the problem here, I don't think the devs will want to work on it as very few Android devices use it, and they're not powerful enough. If you want to run Dolphin on your tablet, you should try to install Windows on it, don't know if it's possible, but I've seen many devices with same specs running Windows, and some Windows + Android, your CPU is totally compatibile.

From the log:
> 28:41:763 Common/GL/GLExtensions/GLExtensions.cpp:2162 E[Video]: Couldn't load function glMultiDrawElementsBaseVertexOES

This appears to be caused by a bug in dolphin's use of GL extensions. Do you know what driver and GL_EXTENSIONS the device uses? A dump from one of the many "gl extension viewer" might be useful.

As an aside, x86_64 seems to work fine on Android here, but the Intel SoC in that likely won't be powerful enough to run much anyway, so support likely won't be a high priority.

Yeah, we still have a driver issue, HD Graphics has very very poor OpenGL support on Windows, so don't expect anything good on Android...The luck for Windows users is the DirectX, which is not as bad as OpenGL support. I use modded drivers on my Laptop (which gave me a better performance), anyway the performance difference between OpenGL and DirectX on Dolphin is scary, while I get 20 FPS on DirectX, I get 6 FPS on OpenGL, and Dolphin runs better on OpenGL than DirectX.

If I remember correctly, the Intel Android driver is based on mesa (the same as their desktop linux) (EDIT2: Apparently I do not remember correctly, not sure what they use, but might be the same codebase as the windows drivers) - which is a completely different codebase than the Windows one. And, in my opinion, much better than the windows one too. Certainly in terms of feature support and correctness.

I had a go at fixing this, I'll get you a link to the apk when the autobuild completes, if you feel like testing it

Give this a go

If it's true, is a pro point, but yet we have a weak CPU...I don't know about X5 8550, but X7 8700 can run The Legend of Zelda The Wind Waker between 25-30 FPS on Windows using DirectX 12 with last official version, Vulkan on Android can be a good thing for these weak CPUs. I hope Intel have good Vulkan drivers...

I mean it's worth trying for the sole fact that the x64 JIT is very mature and well maintained and this device will get a huge head start thanks to that, especially if vulkan is supported

OMG its workin! Thank you so much!

How is the performance? Do you have any graphic issue?
