Merge ~igorluppi/ubuntu/+source/ggml:igorluppi/ggml-0.9.5-3ubuntu1 into ubuntu/+source/ggml:ubuntu/devel

[Igor Luppi]

Fix ppc64el build and check ggml against new hipcc (7.1.0) from proposed

[Igor Luppi (igorluppi)]

Build in ppa: https://launchpad.net/~igorluppi/+archive/ubuntu/ggml-0.9.5-3-ubuntu1/+packages

(-proposed and all ggml archs)

[Igor Luppi (igorluppi)]

Bug #2138906: This is not affecting ggml, it is not using hipcc for ppc64el.
-> tested in ppa with -proposed hipcc from src:rocm-llvm v7.1.0

[Igor Luppi (igorluppi)]

Bug #2138963: This was fixed in this MP. see: https://launchpad.net/~igorluppi/+archive/ubuntu/ggml-0.9.5-3-ubuntu1/+build/32184079

[Igor Luppi (igorluppi)]

It appears that ubuntu/devel is 0.9.5-2 while my branch was based from 0.9.5-3.

[Igor Luppi (igorluppi)]

Now 0.9.5-3 (patches unapplied) is in Ubuntu/devel after a new importer trigger.

[Andreas Hasenack (ahasenack)]

I think you still need to rebase, there are things in the diff that come from 0.9.5-3.

[Igor Luppi (igorluppi)]

Thanks for the review, Andreas!

Actually, it is already rebased. That diff is only showing on the Launchpad webpage because, by the time the merge proposal was opened, the ubuntu/devel branch hadn't imported 0.9.5-3 yet, but now it has.

We can verify that locally with git diff. It's probably a refresh bug in the web UI.

 ggml (0.9.5-3) unstable; urgency=medium

   * CUDA: Adapt not-installed list to new library locations

[Andreas Hasenack (ahasenack)]

So the HIP backend was dropped for ppc64el in 0.9.4-4:
ggml (0.9.4-4) unstable; urgency=medium

  [ Christian Kastner ]
  * Temporarily disable the HIP backend in unstable, until the ROCm stack has
    stabilized again
  * Introduce a build profile for single AMD GPU target, to enable reducing
    Salsa load

  [ Cordell Bloor ]
  * Drop HIP backend for ppc64el
  * Use default CMAKE_HIP_COMPILER as detected by CMake

 -- Christian Kastner <email address hidden> Wed, 03 Dec 2025 22:49:02 +0100

Ubuntu still has it in resolute-proposed, though, for some reason:
ubuntu:
 libggml0-backend-hip | 0.9.4-3 | resolute-proposed/universe | ppc64el
 libggml0-backend-hip | 0.9.5-3 | resolute-proposed/universe | amd64, amd64v3, arm64

debian:
 libggml0-backend-hip | 0.9.5-3 | unstable | amd64, arm64
 libggml0-backend-hip | 0.9.5-4+hip~exp1 | experimental | amd64, arm64

Excuses says:
ggml (0.0~git20250712.d62df60-1 to 0.9.5-3)
Migration status for ggml (0.0~git20250712.d62df60-1 to 0.9.5-3): BLOCKED: Maybe temporary, maybe blocked but Britney is missing information (check below)
Issues preventing migration:
missing build on ppc64el: libggml0-backend-hip (from 0.9.4-3); libggml-dev, libggml0, libggml0-backend-blas, libggml0-backend-vulkan (from 0.9.4-6)
arch:ppc64el not built yet, autopkgtest delayed there
Additional info:
14 days old
Also see bug 2115706 last updated on Tue Jul 1 05:39:03 2025

Acking that libggml0-backend-hip is missing. But that's because in 0.9.5-3 it failed to build. Actually, a test failed:
test 1
    Start 1: test-backend-ops

1: Test command: /<<PKGBUILDDIR>>/obj-powerpc64le-linux-gnu/bin/test-backend-ops
1: Working Directory: /<<PKGBUILDDIR>>/obj-powerpc64le-linux-gnu/tests
1: Environment variables:
1: LLVM_PROFILE_FILE=test-backend-ops.profraw
1: Test timeout computed to be: 10000000
1: ggml_backend_load_best: search path /usr/lib/powerpc64le-linux-gnu/ggml/backends0 does not exist
1: load_backend: loaded BLAS backend from /<<PKGBUILDDIR>>/obj-powerpc64le-linux-gnu/bin/libggml-blas.so
1: ggml_backend_load_best: search path /usr/lib/powerpc64le-linux-gnu/ggml/backends0 does not exist

Because something backends0 doesn't exist anymore. Did 0.9.5-3 pass in debian?
