## PATCH 1/7: doc: detect ignored public headers

**Errors:**
None.

**Warnings:**

1. **Variable `doc_dir` used but not declared** (line ~304 in `lib/meson.build`):
   The code references `doc_dir` in the warning message, but the variable is `d` in the loop.
   This appears to be a copy-paste error from the drivers block.
   ```python
   # Line 225 in lib/meson.build
   warning('public header directory @0@ is not listed in @1@'.format(doc_dir, doc_build_path))
   ```
   Should be:
   ```python
   warning('public header directory @0@ is not listed in @1@'.format(d, doc_build_path))
   ```

**Info:**
- The sed regular expressions correctly extract the needed information from both documentation files.
- The version check for meson (>= 0.60.0) is appropriate for `fs.name()` usage.

---

## PATCH 2/7: doc: document rte_os.h

**Errors:**
None.

**Warnings:**
None.

**Info:**
- This is a documentation-only stub that satisfies the requirement for a generic header to generate documentation from.
- The copyright year (2010-2019) predates the patch (2026), but this is acceptable as it reflects when the OS-specific variants were originally created.

---

## PATCH 3/7: doc: fix typos in rte_bus_pci.h

**Errors:**
None.

**Warnings:**
None.

**Info:**
- Correctly replaces `@bar` with `@p bar` to fix Doxygen parameter references.

---

## PATCH 4/7: doc: fix typos in rte_bus_vmbus.h

**Errors:**
None.

**Warnings:**
None.

**Info:**
- Fixes multiple Doxygen parameter mismatches (missing, extra, misspelled).
- All corrections appear valid based on the function signatures.

---

## PATCH 5/7: doc: add missing globs to doxy-api.conf.in

**Errors:**
None.

**Warnings:**
None.

**Info:**
- Adds `cmdline*.h` and `bpf_def.h` patterns to include previously omitted public headers.
- The wildcard approach is appropriate for the cmdline family of headers.

---

## PATCH 6/7: doc: add missing drivers to doxy-api.conf.in

**Errors:**
None.

**Warnings:**
None.

**Info:**
- Adds 14 driver directories to the documentation build input.
- The list is now alphabetically sorted, improving maintainability.
- The patch notes that cnxk_bphy is intentionally omitted pending bug 1962.

---

## PATCH 7/7: doc: add missing headers to doxy-api-index.md

**Errors:**
None.

**Warnings:**
None.

**Info:**
- Adds 105 missing header references to the documentation index.
- Headers are organized by topic, following the existing structure.
- New "cmdline" section appropriately groups the command-line parsing headers.
- The patch notes that rte_pmd_bphy.h is intentionally omitted pending bug 1962.

---

## Summary

This patch series adds comprehensive checks to ensure all public headers are documented and indexed. One correctness issue was found:

**Required Fix:**
- **PATCH 1/7, lib/meson.build line 225**: Change `doc_dir` to `d` in the warning format string to match the loop variable.

All other patches are correct. The series significantly improves DPDK's documentation coverage by:
1. Adding automated checks for missing headers
2. Creating a stub for the generic rte_os.h
3. Fixing Doxygen syntax errors in bus drivers
4. Including all public headers in the documentation build and index

The approach of excluding cnxk_bphy headers until proper documentation is written (tracked in bug 1962) is appropriate.
