Symbols of Intel Drivers for Windows

SDyul — Tue, 27 Oct 2015 07:13:00 GMT

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,

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

SDyul — Tue, 27 Oct 2015 17:44:29 GMT

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?

Hi Stefan,

Michael_C_Intel2 — Thu, 29 Oct 2015 20:33:13 GMT

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

Please do. I have tested with

SDyul — Fri, 30 Oct 2015 04:20:39 GMT

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,

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,

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

Hi, please try this package.

SDyul — Fri, 20 Nov 2015 18:22:24 GMT

Hi, please try this package.

Got it. Thanks!

Michael_C_Intel2 — Fri, 20 Nov 2015 19:27:10 GMT

Got it. Thanks!

Hi Stefan,

Michael_C_Intel2 — Tue, 08 Dec 2015 15:04:53 GMT

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?

-Michael

Hi I have been able to able

SDyul — Sun, 13 Dec 2015 19:26:21 GMT

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.
