Crash of Intel Driver on Intel X3100 mobile graphic device in DirectX10.

Mon, 09 Nov 2009 03:49:06 -0800

Most application I created (and even some dx10 application available on the net) crash the intel driver (and if leaved alone, the whole system after 5 crash) with either the last (1666) and the previous driver available from Intel website. Are we going to get a fix for this problem (that i've heard from lots of people) or its gonna be forgotten without any kind of help?
There is a way to get a log of the crash to send information to you about it? Someone know WHAT cause the crash and how to circumvent it (i'm willing to make special code to support Intel card :P)?

Please note that the same applications works perfectly fine on nVidia or Ati cards.

Help on QueryPerformanceFrequency()

Mon, 09 Nov 2009 02:14:16 -0800

Hi all, this is my first post. Sorry if i'm asking some noob questions. I posted this help in Atom developer forum, but they refer me here. First of all, SORRY if i posted on the wrong forum.

Currently i'm working on some visual embedded system which is using Atom Z530 (1.6GHz)

My idea was to test the execution time of my algorithm on this platform.
I used the QueryPerformanceFrequency() function in "windows.h" to get the clock frequency counter for high precision.

I did a trail on a Dual Core 3.6GHz and this Atom.
Here are the results
1) 360019000 ~ 3.6GHz for the Dual core.
2.) 3579545 ~ 3.5MHz for the Atom Z530.

I understand that Atom has this SpeedStep technology. But i disabled it in BOIS and set it to use the Maximum CPU. But i still get same frequency.
May i know what am i missing out?

I'm using Visual studio 2005 pro, Windows XP Sp3

Thanks in advance!!

Zone Rendering

I read a white paper about Zone Rendering in the intel Integrated chipsets to reduce the memory overhead... I was wondering if there was any example or source code showing this implementation....

DXVA - 0x887600ff Error returned by IAMVideoAccelerator::Execute()

Tue, 13 Oct 2009 20:51:06 -0700

I am developing Directx Video Acceleration(DXVA 1.0) based AVC Decoder.
I have Intel US15W Embedded Graphics Display adapter. This Display adapter
has Intel GMA 500. I am having Windows XP on my system.

Please correct me If I am wrong that, Intel GMA 500 doesn't support "DXVA_Slice_H264_Short".
I am calling BeginFrame(), sending DxVA buffers using Execute() and then calling EndFrame().
All these fucntion calls return S_OK.

But when I call Execute() to check the status of the frame, by passing "DXVA_Status_H264" buffer,
it returns error code "0x887600ff". Can you please tell me why this error is coming?

Also please let me know, if there any documents provided by Intel for DxVA.
I got hold of "h264_AVC_X4500_Acceration_esardell.pdf". But this is for G45/GM45 chipsets.
Can I use this document for Developing AVC DXVA decoder on GMA 500 chipset also?
Please let me know if any additional information is required. Any help is greatly appreciated.
Thanks in advance.

Hi

One of my friends have a problem regarding the VRAM of intel x3100 ... the VRAM is only 64 MB in windows 7 whereas 128 MB in windows vista .. because of this less VRAM he is not able to play pro evolution Soccer 2009 in full screen ... can anybody help out ...

I need a frame by frame dvd video player software.

Wed, 23 Sep 2009 02:19:49 -0700

I need to watch some reference dvds and videos and I am in need of a good frame by frame viewer. Most of the players fail to do frame accuracy(kmp, vlc, Gom etc). And I do not want to convert whole dvd set to sequential tgas or pngs.I would like to scrub the videos back and forth as good as possible.
I also need some of factors like
Detail enhancement
Color enhancement
Dynamic contrast enhancement
MPEG noise reduction

You have any idea?

Thanks

GMA500 and OpenGL support

Wed, 16 Sep 2009 04:14:18 -0700

So, the hardware supports OpenGL 1.4 and 2.0 but the drivers don't? Whats the deal here?...

Copying of structures

Tue, 15 Sep 2009 17:35:03 -0700

Hi, I am using legacy fortran code and it seems that TYPE structures are copied in many places using the scheme struct1=struct2. Then pointers are deallocated from struct1 (which are really pointers or copies of pointers of struct2). My question is, is struct1 copied I would think it is just pointed to struct2. This scheme has worked for many years but when calling the fortran dll from c#, i many times seems to get a Attempted to Read or Write Protected Memory error. Any help or advice is appreciated.

About GMA 500 Driver Development

Tue, 01 Sep 2009 03:37:52 -0700

I have a simple question: will the driver for the GMA500 support WDDM 1.1? The hardware is DX10.1 capable, but lacks driver support. Vista GMA500 driver is not compatible with Win7, using it leads to a lot of bsod in many operations. With wddm 1.1 memory usage for the dwm hopefully will be reduced, and maybe will get a better 2d acceleration, useful for flash apps. As a last chance, if wddm 1.1 support is not planned, will wddm 1.0 Vista driver be patched to work well under Win7?
