requirement to log in and restart forum every time

The new "feature" where we are logged out automatically and must enter the forum, log in, then reenter the forum, is irksome.  If this is intended as a way to slow down the spam temporarily, I suppose it won't be long before it fails.

I have this same problem on various browsers and various OS (I access the forum from Windows, Android, and linux).

PCIe Root Complex and the PCH

Hello All,

I have a question that's been bugging me regarding the PCIe Root Complex and the PCH and I'm hoping someone will be able to help clear things up a bit.

I've always presumed that the PCIe Root Complex was a combination of the CPU and the PCH as they both contain PCIe Root Ports, thereby connecting PCIe devices to CPU/memory. 

Spurious STALL packets - Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 05)

Hi,

lspci | grep -i usb

00:1a.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 05)
00:1d.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 05)
 

We are having Linux-Servers with Intel USB2 EHCI chipset. When I connect the Bluetooth Dongle’s(Full-Speed), I see repeatedly spurious STALL packets.

FRSTOR Floating-Point Exceptions

I am writing an RTOS and I have some questions about Floating-Point Exceptions generated by the FRSTOR instruction.

The Intel® 64 and IA-32 Architectures Software Developer’s Manual  Volume 2 says that the FRSTOR instruction "might unmask an existing exception that has been detected but not generated, because it was masked. Here, the exception is generated at the completion of the instruction." I have 2 questions related to this:

1) What address will the EIP be when the exception occurs (the FRSTOR instruction or next instruction)?

Display Device Horizontal and Vertical Scaling Question

Hi,

I'm kinda new here, so I'm just gonna cut to the chase. I'd just like to ask what IGFX structure was used in setting/getting the value of Horizontal and Vertical Scaling (Customize Aspect Ratio) in Intel Graphics and Media Control Panel?

I tried IGFX_DISPLAY_CONFIG_1_1 structure but it always returns IGFX_FAILURE.

Please have comments and advise.

Thanks,

John

device for get harware error from motherboard

Tell me please device for diagnosing or receiving error codes from the motherboard of the server (for example, intel s2600j. Ideal universal tool)
It necessary if not possible to boot the server. For example if some memory module have bug or something else.
 

When you see a black screen, the server becomes a black box. May be exists any something device for diagnostics / receive errors in this situation?

Or tell me where to look.

Thanks for your time

3D engine

Hello there,

ok, here we go, I have a dream, make a 3D engine 100% assembler intel only with CPU, I use rotation matrix only for now.

it works of course, but it's slow when I put a lot of pixels.

Recently I decided to include voxels in my engine, and it's slow when I put> = 8000 voxels (20 * 20 * 20 cube) and when I saw that nvidia display 32M voxels (fire) I wonder how they can do it !

And I have a little idea of  the reason: MMU, paging, segmentation. memory.
Am I right?
