(GPU driver）Direct x11 0x887A0006 - DXGI_ERROR_DEVICE_HUNG

[yifengling0]

Lumia950XL with GPU dirver working。
OS : 17134

I wrote an desktop app(arm/arm64） with Direct X11.

I got 0x887A0006 - DXGI_ERROR_DEVICE_HUNG error.

I also checked the dx support with dxdiag command. no error.

Is this a known issue?

PS：UWP directX 11 sample application running well

Hi, which application?

[yifengling0]

https://github.com/yifengling0/angle
with this one. i had portted it to arm & arm64 arch！

I also write a simple directX11 desktop arm app for the testting.

result is the app cann't run on the lumia950xl but running well on windows rt 8.1(Lumia930).

is this is reason why the x86 simulation have problem?

Hi, x86 emulation has an issue because we do not have user mode components for x86. It's not related to this issue. I'll investigate the issue with your app hopefully sometime this weekend. Sounds weird it runs well on a Lumia 930, since the Lumia 930 supports DirectX 9 on Windows RT (by design). Are you sure you've built the app for Direct X 11?

thanks for reply . about x86 emulation cann't use 835 user mode components?
i am sure i am using the directx11 api.

@yifengling0 835's DX shader compiler (and even 850) component is reusable, the DDI isn't because support for Adreno 4xx was removed.

thanks for replay。 since UWP can working well。 can we rewrite the ddi for Adreno4XX？

Turns out we're not properly registering the directx 11 user mode components properly, fixing that hopefully today.

good news， any progress？

Turns out the issue is slightly complex, we got the user mode direct x compiler crashing every minute or so which is also the root cause of the black box glitches. Will need to be looked into, but registration of components was also originally a problem

Fixing would involve switching to a newer DX UMD version, which is harder than it sounds. Hopefully wouldn't have issues with 64-bit pointers when using dxbridge that is being developed for x86 compatibility anyway...

Can you test an ARM32 version with the 1906-directx branch?

Thanks,

Thanks,

OK, i will try later.

I test a desktop arm32 application with newer version . but also got the same error!

I test a desktop arm32 application with newer version . but also got the same error!

but with the RDP or miracast(must run the app at the second srceen) the application can run normally. so i think the problem is not the GPU driver. @gus33000
