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

### Errors

None.

### Warnings

None.

### Info

This patch adds meson build checks to detect public headers that are missing from the documentation index or build configuration. The implementation correctly:
- Uses `fs.name()` to extract filenames for comparison
- Implements exception handling via `doc_ignored_header_suffixes`
- Provides clear warning messages with file paths
- Only enables checks on Linux with meson >= 0.60.0

The sed regex patterns are appropriate for extracting header names and directory paths from the documentation configuration files.

## PATCH 2/7: doc: fix typos in rte_avp_common.h

### Errors

None.

### Warnings

None.

### Info

The patch correctly fixes doxygen grouping command syntax:
- Changes `/**{ AVP device features */` to `/**@{ AVP device features */`
- Changes `/**@} AVP Migration status/ack register values */` to `/**@{ AVP Migration status/ack register values */`
- Changes `/**@} AVP MMIO Register Offsets */` to `/**@{ AVP MMIO Register Offsets */`
- Changes `/**@} AVP Interrupt Status Mask */` to `/**@{ AVP Interrupt Status Mask */`
- Changes `* Access AVP device version values` to `* @{ Access AVP device version values`

All changes balance doxygen grouping commands properly. The patch description correctly explains the issue was masked by incomplete doxygen parsing in older versions.

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

### Errors

None.

### Warnings

None.

### Info

The patch correctly replaces invalid doxygen syntax `@bar` with proper parameter reference syntax `@p bar` in two function documentation blocks for `rte_pci_mmio_read()` and `rte_pci_mmio_write()`.

---

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

### Errors

None.

### Warnings

None.

### Info

The patch fixes multiple doxygen parameter documentation issues:
- Adds missing `@param dev` documentation in several functions
- Corrects parameter names (`chan` vs `channel`, `request_id`, `new_chan`)
- Removes invalid parameter documentation (e.g., `@param type`, `@param flags` where those parameters don't exist)
- Adds missing `@param f` for FILE pointer

All corrections align the doxygen comments with the actual function signatures.

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

### Errors

None.

### Warnings

None.

### Info

The patch adds missing file patterns to the doxygen INPUT configuration:
- `cmdline*.h` to include all cmdline headers (previously only `cmdline.h` was included)
- `bpf_def.h` to include the BPF machine code definitions header

Both additions are appropriate as these are public headers that should be documented.

---

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

### Errors

None.

### Warnings

None.

### Info

The patch adds missing driver directories to the doxygen INPUT list and sorts them alphabetically. All added drivers have public headers that should be documented:
- Baseband: acc, fpga_5gnr_fec
- Bus: pci, vmbus
- Net: avp, ntnic, ring, txgbe, vhost
- Power: kvm_vm
- Raw: cnxk_gpio, ntb

The patch correctly notes that cnxk_bphy is intentionally excluded pending additional documentation work (tracked in bugzilla bug 1962).

---

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

### Errors

None.

### Warnings

1. **RST Documentation Style** (Warning):
   The BPF section uses a nested bullet list structure that could be more cleanly expressed as a definition list:
   ```markdown
   - **containers**:
     ...
     [member](@ref rte_member.h)
     * BPF:
       [load and execute](@ref rte_bpf.h),
       [machine code](@ref bpf_def.h),
       ...
   ```
   
   This mixes markdown list syntax (the `* BPF:` item) within a definition list context. While technically valid, consider restructuring for consistency with the rest of the document's definition list style. However, given the document's overall structure and the fact that BPF is presented as a distinct subsystem with multiple related headers, the current approach is acceptable.

### Info

The patch comprehensively adds missing header references to the API index:
- Device headers: rte_bus.h, rte_cman.h, rte_dev_info.h, crypto headers, event_ring.h
- Device-specific PMD headers: vhost crypto/async, bond 8023ad, cnxk_gpio, various driver PMD headers
- Memory: rte_eal_memconfig.h
- Timers: rte_time.h
- Locks: rte_stdatomic.h, rte_lock_annotations.h
- CPU: power guest channel, power qos, service component
- Layers: net headers, PTP
- QoS: sched common, PIE
- Algorithms: ACL osdep, BPF headers
- Containers: mbuf sub-headers, fbarray
- Packet framework: additional port/table/pipeline headers
- New cmdline section with all cmdline headers
- Basic: reciprocal, UUID
- Misc: class, epoll, hypervisor

All additions are appropriate. The new "cmdline" section is well-organized and groups all command-line parsing related headers together.

The patch correctly notes that rte_pmd_bphy.h is intentionally excluded (same bugzilla issue as patch 6).

---

## Summary

All seven patches in this series are **correct and ready for merge**. The series systematically:
1. Adds build-time validation for documentation completeness
2. Fixes existing doxygen syntax errors in driver headers
3. Ensures all public headers are included in documentation build
4. Adds missing headers to the API index

No correctness bugs, style violations, or process compliance issues were found. The one Warning about RST style in patch 7 is a minor suggestion and does not block merging.
