10.2.5. Possible problems and solutions¶

darktable will detect OpenCL run-time problems automatically. It will then reprocess
everything on CPU; only speed is affected, the final result should not be endangered.

There can be various reasons why OpenCL could fail during initialization phase. We depend
on hardware requirements and on the presence of certain drivers and libraries. In addition
all these have to fit in terms of maker model and revision number. If anything does not
fit, e.g. your graphics driver (loaded as a kernel module) does not match the version of
your libOpenCL.so, OpenCL support is likely not available.

In that case, the best thing to do is start darktable from a console with

darktable -d opencl

This will give additional debugging output about the initialization and use of OpenCL.
First see if you find a line that starts with “[opencl_init] FINALLY …”
This should tell you, if OpenCL support is available for you or not. If initialization
failed, look at the messages above for anything that reads like “could not be
detected” or “could not be created”. Check if there is a hint about
where it failed.

Here are a few cases observed in the past:

darktable might tell you that no OpenCL aware graphics card is detected or that the
available memory on your GPU is too low and the device is discarded. In that case you
might need to buy a new card, if you really want OpenCL support.
darktable might find your libOpenCL.so but then tell you that it couldn’t get a
platform. NVIDIA drivers will often give error code -1001 in that case. This happens
because libOpenCL.so is only a wrapper library. For the real work further
libraries – specific to vendor, device and driver – need to be
loaded. This failed for some reason. There is a structure of files in /etc/OpenCL on
your system that libOpenCL.so consults to find these libraries. Check if you find
something fishy in there and try to fix it. Often the needed libraries cannot be found
by your system’s dynamic loader. Giving full path names might help.
darktable might also tell you that a context could not be created. This often indicates
a version mismatch between (loaded) graphics driver and libOpenCL. Check if you have
left-over kernel modules or graphics libraries of an older install and take appropriate
action. In doubt, make a clean reinstall of your graphics driver. Sometimes, immediately
after a driver update, the loaded kernel driver does not match the newly installed
libraries: reboot your system in that case.
darktable might crash in very rare cases directly during startup. This can happen if
your OpenCL setup is completely broken or if driver/library contains a severe bug. If
you can’t fix it, you can still use darktable with option
“—disable-opencl”, which will skip the entire OpenCL initialization step.
darktable might fail to compile its OpenCL source files at run-time. In that case you
will get a number of error messages looking like typical compiler errors. This could
indicate an incompatibility between your OpenCL implementation and our interpretation of
the standard. In that case visit us in IRC in #darktable on FreeNode or on the
developers mailing list at darktable-dev@lists. darktable.org and report the problem.
Chances are good that we can help you. Please also report if you see significant
differences between CPU and GPU processing of an image!

There also exists a few on-CPU implementations of OpenCL. These come as drivers provided
by INTEL or AMD. We observed that they do not give us any speed gain versus our
hand-optimized CPU code. Therefore we simply discard these devices by default. This
behavior can be changed by setting the configuration variable opencl_use_cpu_devices to
TRUE.

I’m new to Adobe Premiere and GPU acceleration. I started to follow simple tutorial on editing video with Premiere Pro CC that I had «Stopped Working» error after seconds when I hovered on my video or dragged it. Found that problem is because of OpenCL. So I put my settings to «Software Only» to have just CPU rendering.

My hardware and software:

HP ProBook 450 G1
Microsoft Windows 8.1 X64
AMD Radeon 8600/8700M
14.12 AMD Catalyst Omega Software
Intel HD 4600
AMD APP SDK 2.9
Microsoft Visual Studio Ultimate 2013

(For web developing. I’m not a CPP programmer.)

Adobe Premiere Pro CC

I used GPU-Z to have details about my AMD GPU and I saw that OpenCL is disabled and other one (Intel) is enabled.

Image

So I used /program files/adobe/adobe premiere pro cc/gpusniffer.exe and this is the output:

Found 2 devices supporting GPU computation.
OpenCL Device 0 -
   Name: Intel(R) HD Graphics 4600
   Vendor: Intel

After two weeks Googling for my problem I found my answer in playing with regedit.
To have fun with OpenCL on Windows 8.1 and AMD Radeon we must do these:

Only use AMD Catalyst Control Center downloaded from AMD official website. (For me, installer downloaded from HP Support Center didn’t work. I think because it didn’t contains some packages.)
Download and install AMD APP SDK from AMD Developers official website.
Go to C:\Program Files (x86)\AMD APP SDK\2.9\bin. (It will be different based on your version.)
Copy and replace files from x86 folder (OpenCL.dll and amdocl. dll) to C:\Windows\SysWOW64.
Copy and replace files from x86_64 folder (OpenCL.dll and amdocl64.dll) to C:\Windows\System32.
Note: OpenCL.dll files are different with each other. Pay attention.
Open Start and type regedit in search or RUN.
Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors\.
Add amdocl64.dll as DWORD (32-bit) Value. (Do not edit it after creation!)
Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors\.
Add amdocl.dll as DWORD (32-bit) Value.
Restart windows (Because of Catalyst) and start Catalyst.
In Premiere go to File -> Project Settings -> General -> Video Rendering and Playback and set Renderer to Mercury Playback Engine GPU Acceleration (OpenCL).

Note: In Registry Editor, 0 means true (enabled) and 1 means false (disabled) for OpenCL.

Note: regedit must run as administrator.

Done! Adobe Premiere Pro CC works fast and fine. Note: GPU-Z will not show OpenCL enabled. I think because its old version.

Troubleshooting atikmdag sys blue screen error

Most often, atikmdag sys blue screen error occurs due to an incorrectly installed or corrupted AMD/ATI Radeon video card driver. And in most cases, reinstalling or updating helps to solve the problem, but not everything is so simple and simple, there may be other problems.

Check out the similar «atikmpag sys» failure, maybe some solutions will come in handy.

Let’s touch on this topic in more detail and try to fix everything ourselves.

Removing installed drivers

First of all, I suggest removing already installed drivers. I recommend doing this using the Display Driver Uninstaller utility. Its main advantage is that it completely removes the drivers from the system, cleaning up all the tails (the remaining folders and entries in the registry). Works on all operating systems, including Windows 7, 8, 10.

Only a complete removal can guarantee the effectiveness of a new installation.

Before proceeding with the uninstall procedure, download the latest version of the drivers. You can find them on the manufacturer’s website. Come in, choose your video card model, choose your version of Windows and download.

Let’s get started:

The program is free and does not require installation. Therefore, we download it from the official site and launch it.
It is very important to carry out all actions from safe mode. Otherwise, you may get a black screen or other errors. Therefore, we boot from it and move on.
We launch the utility, select the manufacturer of the video card, for convenience, set the «Russian language» and click on the «Delete and restart» button.
The program will automatically start searching for and deleting all leftovers.

Wait for the uninstall process to complete, restart your computer, and re-enter Safe Mode.

If for some reason this utility did not suit you, there are other similar analogues, for example, Revo Uninstaller, Your Uninstaller and others. You can use them.

Installing fresh drivers

After the uninstallation has been successfully completed, you can start a clean installation.

You should already have the latest software downloaded.

In fact, everything is simple here, perhaps the only rule, especially for beginners: install everything automatically, ticking all the items that the program offers us.

More details:

After starting the installer, we will be offered 2 installation options: «Express» and «Custom». If you do not have the necessary experience and necessary knowledge, choose the first one.

We are waiting for the end of the procedure, restart the PC and start it in normal mode.

If you did everything correctly, according to the instructions, then the blue screen (BSOD) with the atikmdag sys error will be resolved.

A blue screen appears after updating

It is also rare for a blue screen to appear after updating Windows or graphics card drivers. In both cases, rolling back the system to a working state can help.

In the second case, you can also do the following:

In the Device Manager, go to the «Display adapters» tab and right-click on your graphics card, then click «Properties».
Go to the Driver section and click Roll Back.
Action needs to be confirmed.

After completing the procedure, do not forget to restart your computer.

If this was the problem, the blue screen will no longer appear.

File replacement

The fact is that when you install fresh software for the video card, the old version of the atikmdag.sys file is moved to the «System32\Drivers» directory, as a result of which Windows uses the old version, and the new one remains unused. Because of this, a blue screen appears.

So let’s try to fix the atikmdag sys BSOD error by replacing the old file with the new one.

To do this:

Download and install the latest drivers for the video card.
Then go to the partition with the installed OS, usually the «C» drive. Next, in the “Windows / System32 / Drivers” folder, find the atikmdag.sys file and give it a new name Atikmdag.sys.old.
Now we go to the «C» drive, open the «ATI» folder, find the Atikmdag. sy_ file and copy it to the desktop.
Open a command prompt. How to do it in Windows 10 read here. Some of the considered methods are universal and are suitable even for Windows XP,7,8.
Enter the following: chdir Desktop and press «Enter».
Now we perform the replacement procedure by typing the command EXPAND.EXE atikmdag.sy_ atikmdag.sys and pressing «Enter».
Copy the new version of the file from the desktop to the «Drivers» folder and restart the PC.

The blue screen should no longer appear.

atikmdag.sys error with code 0x0000003

As a rule, the problem is fixed quite easily, you just need to download the official patch from Microsoft. You can find it here. Before installing it, do not forget to enable automatic updates.

Turning off the quick launch feature

Also, the blue screen can only appear under certain circumstances, for example, when exiting sleep mode, then changing the startup settings can help.

Make sure you are logged in as an administrator before proceeding with the specific steps.

In order to change the settings, you need to:

Click on the start, enter «Power» in the search bar and go to the required section.
In the menu on the left, click on «Button Actions» and go inside the settings.
At the top of the window, click «Change settings».
Remove the checkmark from the quick launch item and click «Save».

Reboot the system.
