When I try to use hardware event-based profiling in VTune (Profiler 2020), I get the error message
Cannot enable Hardware Event-based Sampling due to a problem with the driver (sep*/sepdrv*). Check that the driver is running and the driver group is in the current user group list. See the "Sampling Drivers" help topic for further details.
In the Sampling Drivers section of the use guide it says
Windows* targets: Verify the sampling driver is installed correctly. If required, install the driver.
then asks me to run amplxe-sepreg.exe. This is missing from the bin32 directory. I have reinstalled multiple times.
The amplxe-sepreg.exe application could be found in bin64 folderfor oneAPI beta07 toolkit,
After uninstalling again and installing from the oneAPI package, it worked.

I'm currently trying to run ARM assembly on my DE series board. However when I try to open my project I get the following error on the Intel FPGA Monitor Program:
Error running 'make DETECT_DEVICES'. (java.io.IOException: The pipe is
being closed)
How can I solve that?
Depends on the OS you are running. If you are running on Windows 11, it's not going to work because there is no USB Blaster II driver support for it unfortunately.

Hi Fari,
Regarding the issue with the USB blaster, as mention by ak6dn there will be issues regarding installing the USB blaster in Windows 11 because It is not officially supported yet by Intel. We cannot sure that it will 100% works in windows 11. As for work around to troubleshoot the issue, you can follow the instruction from the link that I have attached below.

I suggest you use a VM with Windows 10 if that's the case.
The FPGA monitor program requires WSL1 with a Linux distro installed on your PC. Make sure WSL1 is set to default, WSL2 is not supported and will result in crashes while trying to compile your code.
To install WSL1 and set it to default, follow this link:
https://learn.microsoft.com/en-us/windows/wsl/install
After installation, launch the installed distro and follow this link step by step:
https://www.intel.com/content/www/us/en/docs/programmable/683525/21-3/installing-windows-subsystem-for-linux.html
Although the document refers to the NIOS II EDS it is also applicable for the FPGA monitor.
Also make sure that the version of Quartus corresponds to the version of the FPGA monitor and keep the Linux distro running in the background while compiling.
I have been wanting to work with Vulkan, the new graphics API and have gotten it up and running with no problems on Windows 7. However I can't get Vulkan to work on linux. When I try running any of the LunarG samples, or even my own code, vkEnumeratePhysicalDevices always says that there are no physical devices. Here is my setup:
OS: Ubuntu 16.04 (LTS) [x64]
GPU: Nvidia Geforce GT 730 2GB GDDR5
Driver: NVIDIA Binary driver - version 364.19 from nvidia-364 (open source)
Vulkan SDK: LunarG v1.0.17.0 [ latest version]
I was wondering if maybe there's a file for my GPU that I need to set an environment variable for, but I really don't know. As I said before, this worked on Windows 7 perfectly, but I can't seem to get this to work this the above configuration. I am able to create an instance with the LunarG standard validation layer and the correct extensions, but vkEnumeratePhysicalDevices doesn't find any physical devices. It doesn't give an error, just says it can't find any physical devices. This has really got me stumped and I would really appreciate the help. Thanks!
Depending on your distribution you may have to install the nvidia-utils package. See this issue on my Vulkan repo for details.
If this isn't the case for you check the directories Karl mentioned and check if there is no other ICD (maybe one from Intel) that may cause troubles. If you're on an optimus system with dual GPU you may need to explicitly activate the NVIDIA GPU.
The 730 should work fine on Linux, at least judging from the Linux hardware reports I got on my database like this one.
You shouldn't have to set an environment variable if the driver installed properly.
One way to check for a proper installation is to look for the JSON file that identifies the driver. For example, an nvidia driver will place a file called nvidia_icd.json in /etc/vulkan/icd.d/. /usr/share/vulkan/icd.d/ is another standard, but less common location.
It may also be the case that your GPU does not support Vulkan. Be sure to check your GPU vendor's web pages to confirm support. You may want to download the driver straight from the vendor's site in order to get one that they say has Vulkan support.
And are you sure that using the "Additional Drivers" page is supposed to give you a Vulkan driver?
You can refer to the loader documentation in the docs section at https://vulkan.lunarg.com for more info.
I'm trying to use NVAPI to get GPU information.
But NvAPI fails to return the data on K20c with NVIDIA_DEVICE_NOT_FOUND
I'm using Windows Server 2012 & the display is driven by Onboard chip.
Is NvApi supported on K20 cards?
Please guide
Usually this is due to the wrong driver being loaded (nouveau instead of nvidia - you can check it with lsmod). Other option is to download and install up-to-date drivers from NVidia.
The command nvidia-smi should work at least and report GPU information.
K20c cards are supported by NVML interface provided Nvidia

This Library provides the monitoring & managing information.
I've got a driver for a custom PCI card, which builds and runs fine on XP. I'm trying to use this custom hardware on W7, and am trying to build and run my driver.
I've got the latest DDK from Microsoft, and build my driver for XP using Windows XP "x86 Free Build Environment". Everything installs & works fine. (Build using a DDK "build" command)
If I use the Windows 7 "x86 Free Build Environment" build environment, everything builds fine. I run it through the PREfast and staticdv code checkers, no errors from either. ( I get a couple of warnings about "The dispatch function 'FooFnc' does not have any __drv_dispatchType annotations" - are these likely to be the issue? )
When I install, the install starts OK (standard error about drivers not being signed), but gets to a certain point and then hangs, then fails with a timeout error. The device then shows up in device manager as installed. At this point the PC won't shutdown or boot, but hangs indefinitely. I'm forced to boot into Safe Mode and uninstall the driver from there.
So my question(s) are:
If there has been a change in the driver model between XP and W7, what's the best way to find it? I can't see anything on MSDN.
How would I go about debugging the driver? The box doesn't start, so it's not like I can run up WinDBG.
Any specific W7 driver gotchas that are hidden away?
I've tried to keep this as generic as possible, but if more detail would be helpful I'll provide more
AFAIK, the biggest changes have been made in video and network drivers. Other drivers retain backward compatibility and can be run on W7 even with no recompiling.
Run your driver under driver verifier and turn on generating crash dumps with a keyboard (very helpful in case of system hangs, you can manually generate crashdump, analyze it and find what was wrong).
Hope this helps!
I'm creating setup for my application in Inno Setup, and I will probably need to install driver sometime in the future. However, I need to know some tips about installing drivers in Inno Setup now, so I can easily add the driver into the setup when it's needed.
Should I force the user to install program only into C:\Program Files\<app>\, or it doesn't matter and I should let him install it even on network drive?
Should I install the driver in C:\Windows\, to make it available anytime (even without network drive), or it doesn't matter as well?
Is it possible to start driver on-demand? I want to release new versions of my program, and I need to create the setup so it doesn't require reboot after updating my app. So is it possible to shutdown the driver, overwrite it with new version, and turn on again (as you can with services) without restarting Windows?
Is it possible to overwrite the driver so easily (as mentioned in question 3), or is it recommended to always fully uninstall the program, and then again install the new version?
Could you please include some additional tips about installing/uninstalling/updating drivers you find important? I'm sure I've missed some important points.
I don't have much driver-experience nor knowledge, so I apologize for somewhat confused questions.
And it is probably important what kind of driver would it be, so there is a related question, which should answer that:
Low level mouse hook and DirectX

Please don't do this, installing an upper-level filter driver on all HID devices is an extraordinarily bad idea. That being said, I'll answer your questions anyways.
When you install a driver, Windows manages where the driver itself gets put (in DriverStore), you don't worry about this.
See #1
For some drivers, yes. For a filter driver above HID, no. You'd have to force remove all mice and keyboards on their system and re-add them (which isn't possible with PS/2 devices).
Yes, it's fairly easy to update a driver given that you correctly version it and require a reboot.
Once again, while I don't want to be discouraging, you're only going to get yourself in a world of hurt via doing this.
