GGML has a function to report the allocated size of a backend buffer. However, this returns 0 if we tried to allocate a buffer and it failed. For memory management purposes, it's important to know how much we were trying to allocate. This extends the API to report attempted sizes for all buffers and whether it succeeeded.
llama
This package provides Go bindings to llama.cpp.
Vendoring
Ollama vendors llama.cpp and ggml. While we generally strive to contribute changes back upstream to avoid drift, we carry a small set of patches which are applied to the tracking commit.
If you update the vendoring code, start by running the following command to establish the tracking llama.cpp repo in the ./vendor/ directory.
make -f Makefile.sync apply-patches
Updating Base Commit
Pin to new base commit
To change the base commit, update FETCH_HEAD in Makefile.sync.
When updating to a newer base commit, the existing patches may not apply cleanly and require manual merge resolution.
Start by applying the patches. If any of the patches have conflicts, the git am will stop at the first failure.
make -f Makefile.sync apply-patches
If there are conflicts, you will see an error message. Resolve the conflicts in ./vendor/, and continue the patch series with git am --continue and rerun make -f Makefile.sync apply-patches. Repeat until all patches are successfully applied.
Once all patches are applied, commit the changes to the tracking repository.
make -f Makefile.sync format-patches sync
Generating Patches
When working on new fixes or features that impact vendored code, use the following model. First get a clean tracking repo with all current patches applied:
make -f Makefile.sync clean apply-patches
Iterate until you're ready to submit PRs. Once your code is ready, commit a change in the ./vendor/ directory, then generate the patches for ollama with
make -f Makefile.sync format-patches
In your ./vendor/ directory, create a branch, and cherry-pick the new commit to that branch, then submit a PR upstream to llama.cpp.
Commit the changes in the ollama repo and submit a PR to Ollama, which will include the vendored code update with your change, along with the patches.
After your PR upstream is merged, follow the Updating Base Commit instructions above, however first remove your patch before running apply-patches since the new base commit contains your change already.
