# DPDK Patch Review: net/hinic3 Series
This is a review of a 7-patch series adding support for new SPx series NICs to
the hinic3 driver.
---
## Overall Series Issues
### Errors
1. **Multiple patches have compilation issues** - Several patches introduce
syntax errors, missing semicolons, and undefined symbols that would prevent
compilation.
2. **Missing meson.build updates** - Patches 3-7 add new source directories
(`htn_adapt/`, `stn_adapt/`) with their own `meson.build` files, but the main
`drivers/net/hinic3/meson.build` is not updated to include these subdirectories.
3. **Inconsistent function naming** - The series introduces functions with
inconsistent naming between patches (e.g., `hinic3_cmdq_get_stn_ops()` vs
`hinic3_nic_cmdq_get_stn_ops()`).
---
## Patch 1/7: net/hinic3: add support for new SPx series NIC
### Errors
1. **Line 38 (hinic3_csr.h)**: Uppercase `X` in hex literal:
```c
#define HINIC3_DEV_ID_SP230 0X0229
```
Should be lowercase `0x0229`.
2. **Line 48 (hinic3_ethdev.c)**: Undefined symbol `HINIC3_DEV_ID_VF_SP920` -
this macro is not defined in the header file, only `HINIC3_DEV_ID_920` is
defined.
### Warnings
1. **Commit message**: "suuport" should be "support" (typo).
2. **Alignment inconsistencies** in `hinic3_cmd.h` - the alignment changes are
inconsistent (some use tabs, some use spaces to different column positions).
---
## Patch 2/7: net/hinic3: add enhance cmdq support for new SPx series NIC
### Errors
1. **Line 85 (hinic3_cmdq_enhance.c)**: Missing `RTE_UNUSED` or parameter
`nic_dev` is unused in `prepare_rss_indir_table_cmd_header`.
2. **Line 169 (hinic3_cmdq_enhance.h)**: Missing space before closing comment:
```c
#endif /*_HINIC3_CMDQ_ENHANCE_H_ */
```
Should be `/* _HINIC3_CMDQ_ENHANCE_H_ */`.
3. **Line 1 (meson.build)**: Missing comma in sources list:
```python
base_sources = files(
'hinic3_cmdq_enhance.c'
'hinic3_cmdq.c',
```
Should have comma after first file.
4. **Multiple typedef changes** - Using `u8`, `u16`, `u32`, `u64` instead of
standard `uint8_t`, `uint16_t`, etc. DPDK uses standard C types.
### Warnings
1. **Inconsistent indentation** in `cmdq_sync_cmd()` function - some blocks
have incorrect indentation levels.
2. **Missing Doxygen documentation** for new public functions in
`hinic3_cmdq_enhance.h`.
---
## Patch 3/7: net/hinic3: use different callback func to split new/old cmdq
operations
### Errors
1. **Line 55-60 (hinic3_nic_io.h)**: Missing semicolons in struct definition:
```c
struct hinic3_nic_cmdq_ops {
prepare_cmd_buf_clean_tso_lro_space_t
prepare_cmd_buf_clean_tso_lro_space
prepare_cmd_buf_qp_context_multi_store_t
prepare_cmd_buf_qp_context_multi_store
```
Each line needs a semicolon.
2. **Line 80-81 (hinic3_htn_cmdq.c)**: Function
`prepare_rss_indir_table_cmd_header` is called before it's defined (defined at
line 93).
3. **Line 38 (hinic3_stn_cmdq.h)**: Missing closing brace or semicolon at end
of struct.
4. **Undefined types** - `u32`, `u16`, `u8` used instead of `uint32_t`,
`uint16_t`, `uint8_t`.
### Warnings
1. **Missing header guards** check - `hinic3_htn_cmdq.h` and
`hinic3_stn_cmdq.h` header guards don't match standard format.
---
## Patch 4/7: net/hinic3: add fun init ops to support Compact CQE
### Errors
1. **Line 614 (hinic3_nic_io.c)**: Unterminated string literal:
```c
PMD_DRV_LOG(ERR, "Set rq cqe context failed,
qid: %d, err: %d, status: 0x%x, out_size: 0x%x",
```
String cannot span lines like this.
2. **Line 666 (hinic3_nic_io.c)**: Redefinition of `nic_dev`:
```c
hinic3_set_rq_enable(struct hinic3_nic_dev *nic_dev, uint16_t q_id, bool
enable)
{
struct hinic3_nic_dev *nic_dev = NULL;
```
3. **Line 669 (hinic3_nic_io.c)**: Undefined variable `dev` used:
```c
if (!dev)
return -EINVAL;
```
4. **Missing function declaration** - `hinic3_nic_tx_rx_ops_init` is called but
not declared.
### Warnings
1. **Commit message**: "fun init" should be "func init" or "function init".
2. **Signed-off-by has leading space** in commit message.
---
## Patch 5/7: net/hinic3: add rx ops to support Compact CQE
### Errors
1. **Line 476 (hinic3_rx.h)**: Missing comma in function declaration:
```c
hinic3_rx_get_compact_cqe_info(struct hinic3_rxq *rxq, volatile struct
hinic3_rq_cqe *rx_cqe
struct hinic3_cqe_info *cqe_info);
```
2. **Line 790 (hinic3_rx.c)**: `if` statement without space:
```c
if(err) {
```
Should be `if (err)`.
3. **Undefined macro** `HINIC3_PKT_TX_TUNNEL_GENEVE` and
`HINIC3_PKT_TX_TUNNEL_IPIP` used but not defined.
### Warnings
1. **Inconsistent brace style** - some functions use opening brace on same
line, others on new line.
---
## Patch 6/7: net/hinic3: add tx ops to support Compact CQE
### Errors
1. **Line 379 (hinic3_tx.c)**: Undefined variable `wqe`:
```c
wqe->task->pkt_info0 =
```
Should be `task->pkt_info0`.
2. **Line 606 (hinic3_tx.c)**: Typo in function name:
```c
return inic3_non_tso_pkt_pre_process(mbuf, wqe_info);
```
Should be `hinic3_non_tso_pkt_pre_process`.
3. **Line 328 (hinic3_tx.h)**: Duplicate enum value:
```c
enum sq_wqe_data_format {
SQ_NORMAL_WQE = 0,
```
`SQ_NORMAL_WQE` is already defined in `enum sq_wqe_type`.
### Warnings
1. **Missing `RTE_MBUF_F_TX_OUTER_UDP_CKSUM`** -
`HINIC3_PKT_TX_OUTER_UDP_CKSUM` is used but the corresponding RTE flag mapping
is missing.
---
## Patch 7/7: net/hinic3: use different callback func to support htn fdir
### Errors
1. **Line 926 (hinic3_fdir.c)**: Wrong parameter type:
```c
hinic3_tcam_alloc_index(struct hinic3_nic_dev nic_dev, uint16_t *block_id)
```
Should be `struct hinic3_nic_dev *nic_dev` (pointer).
2. **Line 942 (hinic3_fdir.c)**: Same issue - missing pointer for `nic_dev`
parameter.
3. **Line 656 (hinic3_fdir.h)**: Missing semicolon at end of function
declaration:
```c
void hinic3_tcam_index_free(struct hinic3_nic_dev nic_dev, uint16_t index,
uint16_t *block_id)
```
4. **Line 750 (hinic3_fdir.c)**: Missing closing brace:
```c
if (index == HINIC3_TCAM_INVALID_INDEX) {
return -ENOMEM;
}
```
The outer `if` block is not closed properly.
### Warnings
1. **Inconsistent parameter types** - Some functions use `struct
hinic3_nic_dev` while others use `struct hinic3_nic_dev *`.
---
## Summary
This patch series has significant issues that need to be addressed before it
can be accepted:
1. **Compilation errors** - Multiple syntax errors prevent building
2. **Undefined symbols** - References to macros and functions that don't exist
3. **Type inconsistencies** - Mix of kernel-style types (`u32`) and standard
types (`uint32_t`)
4. **Missing build system updates** - New directories not integrated into meson
build
5. **Documentation gaps** - New APIs lack Doxygen comments
The patches should be thoroughly tested for compilation before resubmission.
