## Patch 1/8: doc: detect ignored public headers

### Errors

**Error: Resource leak in meson.build `run_command()` usage**
The `run_command()` calls capture stdout into variables (`doc_built_dirs`, `doc_indexed_headers`) but there is no error handling for the command execution itself beyond `check: true`.
If the `sed` command fails partway through (e.g., file read error, permission issue), the script continues with potentially incomplete data.
While `check: true` will cause meson to fail, the failure mode is not graceful.

**Suggested fix:** This is acceptable as-is for a build-time check (meson will abort on failure), but consider documenting the assumption that the files exist and are readable.

---

### Warnings

**Warning: Hardcoded meson version check without rationale**
Line `check_docs = is_linux and meson.version().version_compare('>= 0.60.0')` introduces a version check for meson 0.60.0 without explanation.

**Suggested fix:** Add a comment explaining why meson 0.60.0 is required (likely for `fs.name()` or another feature used in the check).

**Warning: `run_command()` assumes specific sed implementation**
The `sed` commands use `--regexp-extended` which is a GNU sed extension.
On systems with BSD sed (macOS, FreeBSD), this will fail.

**Suggested fix:** Either document that this check requires GNU sed, or use POSIX-compatible sed syntax (though this may be impractical given the regex complexity).

**Warning: Global variables `doc_built_dirs` and `doc_indexed_headers` lack context**
These variables are set in the top-level `meson.build` but used in `drivers/meson.build` and `lib/meson.build` without clear documentation of their contract.

**Suggested fix:** Add a comment at declaration site explaining their purpose and expected format.

## Patch 2/8: doc: document rte_os.h

### Info

**Info: Generic stub header**
This creates a generic/documentation-only version of `rte_os.h` that will be overridden by platform-specific versions at build time.
This is an acceptable pattern for documentation generation.

---

## Patch 3/8: doc: fix typos in rte_avp_common.h

### Warnings

**Warning: Missing closing brace on line 271**
Line 271 adds `@{` for "Access AVP device version values" but there is no corresponding `@}` to close this group.
All three macros that follow (`RTE_AVP_GET_RELEASE_VERSION`, etc.) will be grouped, but the group is never closed.

**Suggested fix:**
```c
/**
 * @{ Access AVP device version values
 */
#define RTE_AVP_GET_RELEASE_VERSION(_version) (((_version) >> 16) & 0xffff)
#define RTE_AVP_GET_MAJOR_VERSION(_version) (((_version) >> 8) & 0xff)
#define RTE_AVP_GET_MINOR_VERSION(_version) ((_version) & 0xff)
/**@} */
```

## Patch 4/8: doc: fix typos in rte_bus_pci.h

No issues found.

---

## Patch 5/8: doc: fix typos in rte_bus_vmbus.h

### Warnings

**Warning: Incomplete parameter documentation in `rte_vmbus_chan_send_sglist()`**
The function takes a `flags` parameter (visible in the function signature in the actual driver code), but the patch removes `@param flags` from the documentation without verifying that the parameter does not exist.

**Suggested fix:** Verify against the actual function signature whether `flags` exists.
If it does, the documentation should remain or be corrected, not deleted.

**Warning: Parameter name mismatch in `rte_vmbus_chan_recv_raw()`**
Documentation refers to `@param channel` but the actual parameter name is `chan` (as used in the corrected version).
This is fixed by the patch, but worth noting for consistency checks.

---

## Patch 6/8: doc: add missing globs to doxy-api.conf.in

No issues found.

---

## Patch 7/8: doc: add missing drivers to doxy-api.conf.in

### Info

**Info: Comment about omitted driver**
The commit message mentions that `cnxk_bphy` is still omitted and tracked in bugzilla bug 1962.
This is acceptable as documented technical debt.

---

## Patch 8/8: doc: add missing headers to doxy-api-index.md

### Warnings

**Warning: BPF list formatting inconsistency**
Lines 219-223 introduce a nested bullet list for BPF headers:
```markdown
  [member](@ref rte_member.h)
  * BPF:
    [load and execute](@ref rte_bpf.h),
    ...
```
This creates a sub-list with only one parent item.

**Suggested fix:** Use a definition list or flatten the structure:
```markdown
  [member](@ref rte_member.h),
  [BPF](@ref rte_bpf.h),
  [BPF definitions](@ref bpf_def.h),
  [BPF ethdev](@ref rte_bpf_ethdev.h),
  [BPF validate debug](@ref rte_bpf_validate_debug.h)
```
Or use RST definition list syntax (see AGENTS.md RST style section) if the structure is converted to `.rst`.

**Warning: Comma inconsistency in "containers" section**
Line 231 adds `[member](@ref rte_member.h)` followed immediately by a new bullet for BPF, but previous list items in the same block end with commas.

**Suggested fix:** Either add a comma after `[member](@ref rte_member.h),` or remove all commas in the list (markdown does not require them, but consistency is preferred).

## Overall Assessment

This patch series improves DPDK documentation coverage by adding missing headers to the doxygen build configuration and fixing existing doxygen markup errors.
The changes are low-risk (documentation only, no runtime code changes) and well-structured.

**Key issues to address before merge:**
1. Close the doxygen group opened on line 271 in patch 3/8 (missing `@}`)
2. Verify parameter documentation in patch 5/8 matches actual function signatures
3. Consider adding rationale comment for meson version check in patch 1/8
4. Standardize list formatting in patch 8/8 (comma usage, BPF sublist structure)

**Correctness:** No runtime correctness issues (documentation changes only).
**Style:** Minor formatting inconsistencies in markdown and doxygen syntax.
**Process:** Properly targets documentation infrastructure; does not require release notes (test/internal infrastructure).
