Hello,

I have a DELL computer with Intel(R) HD Graphics 530 under Win7 64 bits

 

And i develop a 3D application which use opengl. This applications works on other computer but crash on computer with integrated Graphics like HD530.

 

glGenBuffer(1) =>

WindowsError: exception: access violation writing 0xFFFFFFFFC7013EA0

 

 

   
--- OPENGL INFOS ---

       
Vendor: Intel

       
Renderer: Intel(R) HD Graphics 530

       
OpenGL Version: 4.4.0 - Build 21.20.16.4821

       
Shader Version: 4.40 - Build 21.20.16.4821

 

I tried to upgrade my  hd drivers with the last,  but i keep the same error and i still in OpenGL 4.4.0. Is it possible to pass at OpenGl 4.5.0 with this hardware?

My processor is : https://communities.intel.com/external-link.jspa?url=https%3A%2F%2Fark.i...

No GPU metrics for OpenGL application

July 19, 2018, 4:49 am

Hello everyone,

I am trying to use the Intel GPA to profile rendering applications in Qt. When using the GPA with the provided samples, everything works fine and all the metrics are selectable; however when I try to analyze my own OpenGL program, the GPU metrics section is disabled. When displaying a GPU metric, say for example "EU Stalled %" in the System Analyzer from previous analysis sessions, it appears grey with the word "Inactive" right next to it.

What is the reason for this? I am using it on a Dell XPS 13 with an Intel HD Graphics 630 unit and no additional GPU installed. I can provide configuration details if needed, however since everything works as it should with the provided sample programs, I suspect that I am missing an important piece of information about GPU metric collection. I would be very happy if someone could point me to any kind of documentation on this.

Kind regards,

Nicholas

How get value of "GPU load" for Intel HD-Graphics? (Windows 10)

I'm trying to find the code for get value of "GPU load" for Intel HD-Graphics. On Linux we can use tool "intel-gpu-tools". For Windows we can use "Intel(R) Metrics Framework API" but I did not find there how to do it. For example, program "GPU-Z" can get this, but how?

Incorrect Sampler Filter Value

Not sure if this is the right place to report a bug but after spending several hours wondering why I was getting different results despite identical inputs I finally tried out a different capture program (RenderDoc) and found that the filter mode of the sampler shown there was different whereas in GPA it was not.

For what it's worth in GPA when I've selected the problematic DrawIndexed call and selected the input sampler information the filter state is:

D3D11_FILTER_MIN_MAG_MIP_POINT

Under renderdoc it gets read as Min/Mag/Mip: Anisotropic 16x.

SIGFPE in libGLHUD.so

Hi Giselle, nice meeting you at siggraph on tuesday.

I tried GPA (linux) on my app, but it crashed with a floating point error.

I suspect your tool does a division by zero somewhere?

As a rule, I run my games with FP exceptions enabled, so that I can catch all cases of NaN.

It should be easy to reproduce on your end, just add this to a linux app:

#include <fenv.h>
feenableexcept( FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW );

The crash:

[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Hi,

My 64bit UWP app crashes when I try to start it with Intel GPA Graphics Monitor.

I used the VS2017 15.8.1 debugger, which showed me a crash (null pointer access) in shimd3d64.dll

What can I do about it? I need to analyse my app, because C++ AMP code running on NVidia very fast, is running very slow on Iris Graphics 540.

Older versions of GPA?

Hi,

I'm trying to get GPA version 17.3 because Iv been having lots of problems with the newer versions. 18.1 no longer runs with the programs I want it to and 18.2 doesn't even start (it starts but instantly closes) and a problem Iv had with both versions of 18 is that while it's installed no other applications will open (e.g. Autodesk programs). If I want to use anything else I have to uninstall GPA. I don't suppose it would be possible for me to get a download for 17.3?

List of error codes for IGXPIN.EXE / IGXPUN.EXE

September 27, 2018, 3:18 am

Hi there - I'm responsible for packaging and deploying various drivers as individual/standalone applications or packages via MS SCCM for my employer, and more recently have experienced a few problems where either IGXPIN.EXE or IGXPUN.EXE (as part of an Intel driver install) threw up an error in the deployment logs, and subsequently failed to deploy the driver in question. We can often get around using them altogether via DPINST.EXE, but there's an extra level of complexity in crafting an uninstaller if we use DPINST, so where possible I'd prefer to use the provided install utility from Intel (albeit silently).

 

So basically, I'm posting to ask if there's a list of error codes and their meanings for these two executables?

 

Most recently we've seen exit codes 65 and 4 from IGXPIN when installing Intel HD Graphics 520 and 620 (using confirmed correct drivers, both from Intel and OEM), but we're having difficulty troubleshooting without a reference to the meanings of those codes.

 

Any help would be gratefully accepted! Thanks in advance...

Hello,

​Im trying to get this profiler to work but I have the same error using System Analyzer, Frame Analyzer or other.

Application Error Failed to connect to the application. Contact the Graphics Performance Analyzer support team. 
Im able to see the device and connect, after that I got a screen to and select Analyzable Applications, after I select the APP I get an Error.

Is there some special setup Unity side? Developer Mode, Write to External Memory, Snapdragon above 820? Or like Mali, install a plugin inside Unity project?

I have no problem using others profiler as Adreno Profiler, Snapdragon Profiler or Mali Graphic Profiler.

Appreciate any help.

Hello,

Has anyone had any luck getting the perf marker names in a capture from UE4?

I haven't used GPA in a while, but I'm sure it used to work.

Captures are working fine aside from everything being a nameless draw call.

 

Thanks!

Comparison between GPA version 17 and 18 (grid with GPU duration of events)

October 16, 2018, 2:32 am

Hello,

 

First of all many thanks for this useful tool (Intel GPA), that we can use free of charge.

Second, I’d like to make a complain about the new UI introduced this year.

I prepared an image composition with a comparison between version 17.3 and 18.3. In the 17 version I found very useful the grid with the draw events (markers), because I could immediately spot the GPU duration of each of them, and identify the more costly ones. In the example used in the attached image you can see it in the 17.3 grid that they are the “BasePass” and the “PostProcessing” (each of them about 600 us). Then I could also expand the subtree of PostProcessing for example, and spot the subevent of TAA to be the more costly (about 200 us).

But how can I have the same in the 18.3? You see in the left part of the image, the event list of the 18.3 version doesn't show the timings. I can see if I select one of them the duration is reported on the top left, but it is very inconvenient to select each of them one by one, especially in subtrees that can have many entries.

Thanks
Fabio

Error opening captured frame from project made with UE4 + DX12

Hello,

I made a simple project with UE4 (version 4.20.3), to check if it's possible to capture a frame using DX12 with the last version of GPA (18.3).

The capture worked (ctrl-shift-C) and I see a file saved with the .gpa_frame extension in the Docs/GPA folder.

But if I try to open it with the Frame Analyzer I get this error:

"An internal error occured. Graphics Frame Analyzer may fail to work correctly. Reopen the frame to fix the issue.".

I tried more times to reopen the frame, but without success.

Is there anything I can do? I'm using a PC with a GeForce 1080 ti and the latest nvidia drivers (416.34).

 

Thanks,

Fabio
