## What this PR does / why we need it?
Fixes several documentation issues in the msprobe debugging guide as
reported in #6065:
1. **Remove unnecessary `cat` heredoc wrapper**: The example
configuration section used a `cat <<'JSON'` bash wrapper around the JSON
config. Simplified to a plain JSON code block.
2. **Fix duplicate chapter numbering**: Two sections were both numbered
'2'. Renumbered sections sequentially (0-6).
3. **Fix msprobe command**: Changed `msprobe graph_visualize` to
`msprobe -f pytorch graph` in section 5.2 Visualization.
4. **Remove backward-related content**: Since vllm is inference-only (no
training), removed all backward pass references including backward
tensor examples, parameter gradient examples, and backward descriptions
from dump.json explanations.
## Does this PR introduce _any_ user-facing change?
Documentation improvement only. No code changes.
## How was this patch tested?
Manual review of the markdown file to verify all 4 issues from #6065 are
addressed.
Closes#6065

## Summary
- Enhanced `check_gdn_layer()` function to properly detect GDN layers in
multimodal models
- Added support for checking `text_config.layer_types` in addition to
root-level `layer_types`
- Fixed potential None reference errors when `layer_types` attribute is
missing
## Changes
- Modified `vllm_ascend/utils.py`:
- Replaced `hasattr()` check with safer `getattr()` approach
- Added fallback to empty list when `layer_types` is None
- Added secondary check for `text_config.layer_types` to support models
like Qwen-Omni
## Motivation
Previous implementation only checked `layer_types` at the root config
level, which failed to detect GDN layers in multimodal models where this
information is nested under `text_config`. Additionally, it could raise
errors when `layer_types` was None.

### What this PR does / why we need it?
This PR introduces global CPU slicing for Ascend NPUs to ensure
non-overlapping CPU partitions, addresses IRQ binding logical errors on
A3, and enhances the logic for determining total NPUs in CPU allocation.
These changes are necessary to optimize CPU resource management and
improve system stability.
- **Global CPU Slicing**: Introduced a global CPU slicing mechanism for
Ascend NPUs to ensure non-overlapping CPU partitions across multiple
processes or data parallel groups, preventing resource contention.
- **Improved IRQ Binding for A3 Devices**: Refined the IRQ binding logic
specifically for Ascend A3 devices, correctly mapping logical NPU IDs to
physical card and chip IDs for accurate npu-smi queries and preventing
multi-process overwrite of IRQ settings.
- **Enhanced NPU Count Determination**: Improved the logic for
determining the total number of logical NPUs, prioritizing NPU mapping
information to ensure more accurate CPU allocation.
- **Minimum CPU Requirement**: Established a minimum requirement of 5
CPUs per NPU for binding, reserving specific cores for IRQ, main, ACL,
and release operations to ensure stable operation.

### What this PR does / why we need it?
This pull request refactors the dispatch mechanism for the
**triton-ascend-specific operators** `insert_slice`, `extract_slice`,
and `get_element` to ensure compatibility with both CANN 8.5 and 9.0.
A unified helper function, `_resolve_triton_ascend_op`, has been
introduced in `vllm_ascend/ops/triton/triton_utils.py`. This function
dynamically resolves these operators by first attempting to import them
from the `triton.language.extra.cann.extension` module, which is present
in newer CANN versions. If that fails, it falls back to the standard
`triton.language` module.
This approach centralizes operator dispatch logic, allowing individual
Triton kernels to use these functions without being aware of the
underlying Triton/CANN version. All call sites have been updated to use
these new unified functions.
### Does this PR introduce _any_ user-facing change?
No. This is an internal refactoring of operator implementations and does
not introduce any user-facing changes.
### How was this patch tested?
CI is expected to pass with existing tests.

### What this PR does / why we need it?
Remove hardcoded ASCEND910_95 usage in csrc custom-op host/tiling code
and
select the SoC target at CMake configure time.
- Probe CANN headers with check_cxx_source_compiles:
prefer platform_ascendc::SocVersion::ASCEND950, fallback to
ASCEND910_95.
- Export the selected enum/config string via shared compile definitions
(VLLM_ASCEND_950_SOC_ENUM / VLLM_ASCEND_950_SOC_CONFIG).
- Apply the shared macros to affected paths (moe_gating_top_k,
add_rms_norm_bias) to avoid per-file hardcoding.
- Keep behavior unchanged; this is an internal build-compatibility fix
for CANN 8.5 and 9.x.

### What this PR does / why we need it?
- This PR fixes an issue with weight format conversion for unquantized
models running on Ascend 310P devices.
- The changes refactor the logic for converting weights to the
FRACTAL_NZ format. Previously, this was handled in a 310P-specific
linear layer implementation (`AscendUnquantizedLinearMethod310`). This
implementation has been removed, and the logic is now centralized in the
`maybe_trans_nz` utility function. This function now checks if the
device is a 310P and applies the NZ format cast accordingly for
`float16`/`bfloat16` weights.
- This refactoring simplifies the code by removing platform-specific
duplication and ensures correct weight handling for unquantized models
on 310P.

`mxfp_compat` only provides dtype/symbol compatibility helpers for
different `torch_npu` versions, but it was placed under

### What this PR does / why we need it?
PR #5632 introduced a bug by replacing some branches gated by enable_sp
with enable_flash_comm_v1. As a result, when enable_shared_expert_dp is
enabled alone (i.e., VLLM_ASCEND_ENABLE_FLASHCOMM1=0 and
VLLM_ASCEND_ENABLE_FLASHCOMM=0), the behavior becomes inconsistent with
the previous logic and leads to accuracy issues. This PR restores the
original enable_sp-based branching to recover expected behavior and
accuracy.

### What this PR does / why we need it?
This was meant to be merged in #6536, but I accidentally restored a
commit. You can find the relevant discussion
[here](https://github.com/vllm-project/vllm-ascend/pull/6536#issuecomment-3882883471).
Since `self.pass_config.enable_sp` is forcibly set to `False` in the
[source
code](f176443446/vllm/config/compilation.py (L1066)),
this section will no longer verify whether the generated cudagraph
shapes are multiples of both `uniform_decode_query_len`
(`num_speculative_tokens + 1`) and `tensor_parallel_size`.
This PR enables the `num_speculative_tokens + 1` and
`tensor_parallel_size` check upfront. Therefore, it won't silently round
up the `cudagraph_size` and throw a cryptic error for the user.
A typical example of this cryptic error looks like:
```
ValueError: could not broadcast input array from shape (196,) into shape (14,)
```

There will be random ouputs if we run model with GDN attention in graph
mode:
```python
prompts = [
"1. Who are you?",
]
sampling_params = SamplingParams(temperature=0.6, top_p=0.95, top_k=40, max_tokens=32)
sampling_params = SamplingParams(temperature=0.0, top_p=0.95, top_k=40, max_tokens=5)
llm = LLM(model="/home/model/Qwen3-Next-80B-A3B-Instruct",
tensor_parallel_size=4,
distributed_executor_backend="mp",
gpu_memory_utilization=0.7,
speculative_config={
"method": "qwen3_next_mtp",
"num_speculative_tokens": 3,
},
compilation_config={
"cudagraph_mode": "FULL_DECODE_ONLY",
"cudagraph_capture_sizes": [8],
},
max_model_len=4096,
enable_prefix_caching=False)
outputs = llm.generate(prompts, sampling_params)
for output in outputs:
prompt = output.prompt
generated_text = output.outputs[0].text
print(f"{output.prompt_token_ids=}")
print(f"{output.outputs[0].token_ids=}")
print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")
```
Before appling this change, the outputs was:
```text
output.prompt_token_ids=[16, 13, 10479, 525, 498, 30]
output.outputs[0].token_ids=[3555, 323, 279, 1112, 279]
Prompt: '1. Who are you?', Generated text: ' What and the... the'
```
After applying this change, the output is:
```text
output.prompt_token_ids=[16, 13, 10479, 525, 498, 30]
output.outputs[0].token_ids=[3555, 374, 697, 829, 30]
Prompt: '1. Who are you?', Generated text: ' What is your name?'
```
**Why does this change sovle the problem?**
Now, `query_start_loc` is padded because of `fia`.
But, for `gdn-attention`, padded version of `query_start_loc` will cause
accuracy problem.
So, we need an unpadded version of `query_start_loc` named
`gdn_query_start_loc` and use it in `gdn-attention`, it works fine.

### What this PR does / why we need it?
[Refactor][EAGLE] 7/N Merged PCP and disable_padded interface into
eagle_proposer.py
This pull request significantly refactors the speculative decoding
mechanism by merging Parallel Context Processing (PCP) and Multi-Token
Prediction (MTP) functionalities directly into the eagle_proposer.py.
The changes aim to enhance the efficiency and correctness of distributed
speculative decoding, particularly by enabling the Eagle feature to work
seamlessly with the disable_padded interface. This involves detailed
adjustments to attention metadata, input/output processing, and state
management to ensure proper operation in parallel environments.
1. The PCP and MTP features are migrated to the eagle_proposer.py
2. The Eagle and PCP features are integrated
3. Enable the eagle feature to use the disable_padded interface

### What this PR does / why we need it?
This PR fixes a `Stale file handle` error that occurs during doctests in
the CI environment. The error appears when loading models from
ModelScope, likely due to issues with network file systems used in CI.
The fix involves setting the `MODELSCOPE_HUB_FILE_LOCK` environment
variable to `false` in the `run_doctests.sh` script. This disables file
locking in the ModelScope hub, which is a common workaround for this
type of file system error.
### Does this PR introduce _any_ user-facing change?
No, this change only affects the CI test execution environment and has
no impact on users.
### How was this patch tested?
This change is validated by the CI pipeline. A successful run of the
doctests indicates that the fix is effective.

### What this PR does / why we need it?
**BUG**
When using prefill-decode disaggregation + MTP + full graph
+asynchronous scheduling, the KV cache pulled by decode nodes from
prefill decodes does not include spec tokens. As a result, the
total_num_scheduled_tokens obtained by decode nodes from the scheduler
lacks spec tokens. When determining whether to enqueue the full graph on
decode nodes, the condition for uniform_decode `
scheduler_output.total_num_scheduled_tokens == self.input_batch.num_reqs
* max_query_len` is not met, leading to the current instance not being
enqueued into the full graph.
The above situation leads to both full graph and eagle mode instances
coexisting in the decode instances. Due to the synchronization wait of
MoeDispatch, the decode instances in full graph are significantly slowed
down by the instance in eagle mode.
**Solution**
The scenario is PD separation + MTP + Full Graph + asynchronous
scheduling.
On the decode nodes, the spec tokens of the request with KV cache from P
need be padded. Then, the padded spec tokens will be rejected by
sampling. This operation ensures that the uniform_decode condition is
satisfied when determining whether decode nodes are included in the full
graph, thereby guaranteeing that all decode instances are present in the
full graph and avoiding synchronous waiting for MoeDispatch.

### What this PR does / why we need it?
This pull request resolves an attention accuracy issue by enhancing the
AttentionMaskBuilder310 to correctly handle the maximum model length.
The change ensures that the attention mask generation process is
properly parameterized by the model's configuration, rather than relying
on a fixed internal value. This leads to more accurate attention mask
creation, which is crucial for the correct functioning of the attention
mechanism.
