I’m a little confused about the pixelpipes. In the documentation only four pixelpipes are documented, but when I start darktable in opencl debug mode, I see five pixelpipes:
0.147102 [opencl_priorities] these are your device priorities:
0.147104 [opencl_priorities] image preview export thumbs preview2
0.147106 [opencl_priorities] 1 0 0 1 -1
0.147108 [opencl_priorities] 0 -1 1 0 0
0.147109 [opencl_priorities] show if opencl use is mandatory for a given pixelpipe:
0.147110 [opencl_priorities] image preview export thumbs preview2
0.147112 [opencl_priorities] 0 0 0 0 0
I think this is the second darkroom window, and effectively it’s not described in the opencl configuration help (probably because it was added latter than when most of that section was written).
I’am sorry, but I’am still confused what the preview2 is for. There is no doubt on the preview (the old one). But preview2? The manual still doesn’t help here, see: opencl/multiple devices.
Could someone explain what exactly preview2 is for?
