Hi Guixers,

Incoming are two patches to update the rocm packages (AMD's OpenCL stuff) to the latest version. With this I can use OpenCL in Darktable with my current gen GPU (note: I'm not on linux-libre, which likely impacts what cards can be used).

I tested that everything builds and darktable-cltest reports successful output, as well as rocminfo. E.g. running

./pre-inst-env guix shell rocm-opencl-runtime rocm-device-libs opencl-icd-loader darktable -- darktable-cltest

A few quick notes on these patches. Most of this was discussed on IRC recently, but for the record:

1. llvm-for-rocm: The first patch updates this to use llvm-14, which is what the current rocm version is based on.

2. rocm: All of the packages are updated in one commit as they share a version number and there some interdependencies.

3. rocclr: This is no longer meant as a standalone package: cmake will output a warning and there is no install to be done. It is meant to be included in packages that use it. I've made a plain origin for the rocclr source that is needed (see rocm-opencl-runtime that uses it) and renamed the old version to rocclr-4 since that will still build/install in case it is of use.

This is the commit that changed the build behavior, active since v4.5 at least: https://github.com/ROCm-Developer-Tools/ROCclr/commit/df1449608e92c9e42b4ce5799e6eb51934ae7d4a

4. Relatedly, both Arch and Gentoo build rocclr before building rocm-opencl-runtime, but this doesn't seem to do anything. Unfortunately the rocm readmes are unclear/not up to date on exactly what is needed. From my testing, just setting a configure flag to point to the rocclr source is all that is needed.

The Arch and Gentoo recipes are here:

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=rocm-opencl-runtime

https://gitweb.gentoo.org/repo/gentoo.git/tree/dev-libs/rocm-opencl-runtime/rocm-opencl-runtime-5.0.2.ebuild

We can do the same thing by adding in this phase for rocm-opencl-runtime. I did not see any change in the final output and everything (with Darktable) seemed fine without it. It will take a little longer to build as it does build rocclr explicitly. Anyway, in case it is of use to anyone, here is the code

          (add-before 'configure 'configure-rocclr
            (lambda* (#:key inputs #:allow-other-keys)
              (invoke "cmake" (string-append "-DAMD_OPENCL_PATH="
                                             #$(package-source this-package))
                      "-B build-rocclr" "-S" #$rocclr-src)
              (invoke "make" "-C" "build-rocclr")))

Okay, that's it! Overall is mostly updating hashes and some patches, other than the rocclr notes above. I hope I got the (long) commit message correct on the second patch. The changes work well for me locally.

Thanks!
John
