Hi Ulrich,
Just want to say a big Thank You for "switch config variable
opencl_use_pinned_memory to TRUE"
For me the speed improvement is very noticeable.
When set to "TRUE" - I am exporting the control image for 34s and worse
is 39s
When set to "false" - I am exporting the same image for about 44s and
worse is about 58s
The darktable area is way more responsive. Also I can see the processor
have freed up quite a bit. If I do not use open CL it would hit
consistently 100% on all cores - now it hovers around 75% on all cores.
I am very pleased with the results of the switch!
Thank you once again...

The flag will mostly effect situations where tiling comes into play.
That's the case for GPUs with low memory and for modules with high
memory demand (e.g. equalizer).

Yes, it's working now. I guess the crash must have been a coincidence.
Slower if anything, but there isn't much in it. I can't be sure.
