# DPDK Patch Review

## Patch: vhost: remove dependency on PCI library

### Summary
This patch removes the PCI library from the vhost library's meson.build dependencies, as it is no longer needed after the async datapath switched to dmadev.

---

## Review Findings

### Correctness
**No issues found.**

The change is straightforward: removing 'pci' from the `deps` list in meson.build. This does not introduce any resource leaks, use-after-free conditions, or race conditions.

### Code Style
**No issues found.**

The patch modifies only a meson.build file. Meson file style requirements are met (4-space indentation, alphabetical ordering maintained).

### API and Documentation
**Warning:**

**Missing release notes entry.** The removal of a library dependency should be documented in the release notes under `doc/guides/rel_notes/release_*.rst`. While this is a build system change rather than an API change, it affects anyone who may have relied on transitive PCI dependencies when linking against the vhost library. Document this as a removed dependency.

Suggested addition to release notes:
```rst
* **vhost: Removed PCI library dependency.**

  The vhost library no longer depends on the PCI library after the async
  datapath switched to dmadev (commit 53d3f4778c1d).
```

### Process Compliance
**No issues found.**

- Fixes tag is present and correctly formatted
- Target commit exists (53d3f4778c1d)
- Change is appropriate for the stated reason

## Summary

**Warnings: 1**
- Missing release notes entry for dependency removal

**Errors: 0**

**Recommendation:** Add a release notes entry documenting the dependency removal, then the patch is ready for merge.
