Hi everyone, I've tried to get the darktable photo editor
https://www.darktable.org to work=
, and there's more to it than image support...
First, I've picked up funfunctor's patches (mentioned in bug 99553), they
applied cleanly to master (except for the little one-line "=3D 1"=
since the
r600/radeonsi split happened, but that was trivial to fix). My branch with =
them
is https://=
github.com/myfreeweb/mesa/tree/clover-image
Second, there was some weird mismatch between libclc's headers and darktabl=
e's
code, and I've had to do:
%s/write_only image2d_t/image2d_t
and
%s/__image2d_t/image2d_t
on all files in PREFIX/share/darktable/kernels.
Third, the liquify.cl kernel triggered the
https://bugs.llvm=
.org/show_bug.cgi?id=3D36679 crash (which is fixed in llvm 7...
but I just removed the function body to proceed without this particular eff=
ect)
And finally, with all kernels compiled, darktable benchmarked CPU vs GPU and
found the CPU to be a bit faster (yay for Ryzen) and disabled OpenCL usage.
Enabling OpenCL usage in the settings and then double clicking on an image.=
..
uhh... hard locked the GPU :D
