After initially running apparently correctly, when started for a
second time dt fails to load with opencl .....
"[opencl_init] could not get platforms: -1001"
Very strange ...

Running Manjaro/Arch with current git.
OpenCL appears to be now running correctly on my system but I have a
couple of questions.
1.)Terminal shows some failures
8027.382463 [pixelpipe_process] [full] using device 0
8027.388069 [opencl_pixelpipe] couldn't copy image to opencl device
for module rawprepare
8027.389173 [opencl_pixelpipe] could not run module 'rawprepare' on
gpu. falling back to cpu path
8027.389284 [opencl_pixelpipe (b)] late opencl error detected while
copying back to cpu buffer: -5
8027.389307 [pixelpipe_process] [full] falling back to cpu path
8043.607297 [pixelpipe_process] [full] using device 0
Is this a simple failure in one module and can it be ignored? (This
is zoom 200%)?
2.) The checkboxes for OpenCL in the preferences are grayed out ... why?
David
On debian systems there is a package clinfo which gives you diagnose of
opencl - don't know about Arch etc.
This is what I see after suspend-to-ram etc.
Before dt. works
After awake it does some operations and then tells me
8027.389284 [opencl_pixelpipe (b)] late opencl error detected while
copying back to cpu buffer: -5
8027.389307 [pixelpipe_process] [full] falling back to cpu path
clinfo then tells me: number of platforms: 0
which means: opencl stopped working ...
I have to restart the whole computer - not only darktable - to get this
working again since this is a OS problem, not one of dt.
So you might investigate in this direction.
