Symbols of Intel Drivers for Windows

[SDyul]

Hello, Where I can find the pdbs for intel drivers on windows 10? I am porting here one small example from dx11 to dx12 when i run it i get this crash. Unhandled exception at 0x00007FFD5D57053B (igdusc64.dll) in Shadows.exe: 0xC0000005: Access violation reading location 0x0000000000000038.

Supplying the pdbs will be very useful for discovering the reason. Now the only thing that i can deduce is that somebody is accessing a null pointer.

The example is here. https://github.com/kingofthebongo2008/examples/tree/master/msm

Hi Stefan,

Unfortunately the driver symbols are currently not available outside of Intel. I am talking to a couple engineers about the issue you are seeing, if it turns out to be a driver issue I will work with out driver team to investigate and fix. Your Null pointer theory seems sound to me though.

Also we have a tutorial series on Migrating app to DirectX, part 2 was posted last week. You can view the series here.

Hi Stefan,

Can you get us a minidump and if possible the shader being compiled at crash? Can you also fill in the template below? The additional info will help as I am rather convinced this is a driver issue. Thanks.

Hi Stefan,

We compiled and ran your example on Win10 on the latest public 15.40 driver on a 5th Generation Core system things work. I suggest trying the same driver on your system and seeing what happens.

The driver can be downloaded from here.

I did a mistake the code in github was with the warp device.

I have enabled the hardware device again.

I have also a dump file.

Hello,

Any information on this?

[Michael_C_Intel2]

Hi Stefan,

Have you tried on the latest driver yet? If so then I need the template from previous post filled in and I will have to file a ticket and get our driver team to debug.

-Michael

[SDyul]

Please do. I have tested with this version, which is the latest one now.

win64_15407.4279.zip

If possible to raise the priority, because actually i am blocked, the hardware is unusable with this crash.

Hi Stefan,

Was down with a bad cold last week, causing my delayed responses. I will get a ticket filed and see if I can bump the priority.  But I can't file the ticket until the template below is filled in. This the info our driver team needs to properly investigate:

Hi Stefan,

Do you have a working binary sample for this issue. We are unable to reproduce the issue with the supplied code, the sample keep crashing on a file load.

Thanks,

-Michael

[SDyul]

Hi, please try this package.

[Michael_C_Intel2]

Got it. Thanks!

[Michael_C_Intel2]

Hi Stefan,

We have been unable to to reproduce this issue. We have tried the driver you reported 4279, and the latest public driver 4300. Ate there any system setup other environment variables/system setup items you can think of that we can try?

Hi I have been able to able to isolate a shader that crashes the driver.

When i remove optimizations during the shader compilation, everything is fine. I will post soon the problematic shader.
