3d9954eff0 [Bugfix] Use hf_text_config instead of hf_config to support multimodal PD-Disaggregated (#5205)
### What this PR does / why we need it?
In code files such as`mooncake_connector.py`,
`vllm_config.model_config.hf_config` is used to get the LLM configs.
This approach works for LLMs, but not for multi-modal models. For
multi-modal models, `vllm_config.model_config.hf_text_config` must be
used instead to get the LLM configs.

### Does this PR introduce _any_ user-facing change?
No.

ea6206bb18 [bugfix][ACLGraph][MTP] deletes cudagraph_batch_sizes in MtpProposer (#5183)
### What this PR does / why we need it?
This PR deletes `cudagraph_batch_sizes` in `MtpProposer` and reuses the
one in `NPUModelRunner`.

During our deployment of DeepSeek-V3.2 with MTP across machines 2P2D and
conducting AISBench stress testing, an error occurred (see below). After
investigation, we found that
`compilation_config.cudagraph_capture_sizes` is modified by
`adjust_cudagraph_sizes_for_spec_decode` in `NPUModelRunner`. This
modification only updates `cudagraph_batch_sizes` in `NPUModelRunner`
but is not synchronized to `MtpProposer`. After discussion (CC @yiz-liu)
, we believe it is unnecessary to maintain `cudagraph_batch_sizes` in
`MtpProposer`; it should directly use the variable from
`NPUModelRunner`.

cc23067f1e [refactor] refactor weight trans nz and transpose (#4878)
### What this PR does / why we need it?

Now `VLLM_ASCEND_ENABLE_NZ` will have three options:
0: disable nz;
1: only quant case enable nz;
2: enable nz as long as possible;

And `VLLM_ASCEND_ENABLE_NZ`=1 by default.

All cases are shown in the table below:

|  | W4A4 | W4A8 | W8A8 | fp16/bf16 | fp32 |
|---|---|---|---|---|---|
| trans nz | can't support nz | trans nz by default | trans nz by
default | trans nz when VLLM_ASCEND_ENABLE_NZ is 2 | can't support nz |
| transpose | only support not transpose case | only support transpose
case | only support transpose case | linear: only support not transpose
case<br>gmm: only support transpose case | same to fp16/bf16 |

Some exceptional cases:
1. MLAPO op need to do some additional processing on the weights,
including trans nz. If use MLAPO op, some weight will be transformed to
nz forcely;
2. MLA/SFA's weight `W_UV` will be used by op
`torch.ops._C_ascend.batch_matmul_transpose`, and this op can't support
nz currently;

### Does this PR introduce _any_ user-facing change?
Now fp16/bf16 weight will not trans nz by default.

### What this PR does / why we need it?
vLLM community has integrated their MooncakeConnector. The original
scripts will now find this MooncakeConnector instead of the one from
vLLM-Ascend. All scripts that involve using the MooncakeConnector need
to be modified to another name.

### Does this PR introduce _any_ user-facing change?
Yes, users need to use a new name to load vLLM-Ascend MooncakeConnector.

### How was this patch tested?

acc3578f58 [Graph][Fusion]Add new pattern for AddRmsnormQuant with SP. (#5077)
### What this PR does / why we need it?
1. In addition to
[#4168](https://github.com/vllm-project/vllm-ascend/pull/4168),
[#5011](https://github.com/vllm-project/vllm-ascend/pull/5011), this PR
adds two more pattern for AddRmsnormQuant with SP enabled. The key
difference is to insert an additional `maybe_all_gather_and_maybe_unpad`
between `addrmsnorm` and `quantize`.
2. This PR also introduce another api `torch.ops.vllm.quantize`, so that
we pass `input_scale` and `input_scale_reciprocal` at the same time.
This is because `npu_add_rms_norm_quant` and `npu_quantize` requires
different `div_mode`. To avoid introducing additional reciprocal
calculation in runtime, we have to pass both of them to quantize api.
3. Removes redundant `AscendQuantRmsnorm`.

This PR adds a function `is_moe_layer` to mlp_tp, which supports MLP TP
in models with both mlp and moe, such as deepseek or chat GLM.

### What this PR does / why we need it?
We will expose the enabling switch for npugraph_ex to better facilitate

### Does this PR introduce _any_ user-facing change?
Previously, the enable_npugraph_ex switch would trigger an error; now we
have removed the error reporting mechanism to better facilitate
subsequent optimization efforts.
Basic functionalities are available in CANN and torch_npu for Q3, while
advanced optimizations will depend on the Q4 release.

Reason:

We distinguish the branches based on the applicable scenarios of
pagedAttention and fusedInferAttention, making the code more clear.

At the same time, it is convenient for the subsequent iterations of
sliding_window and sinks and removePA ops after FIA is ready.

Todo:

remove PA ops after FIA is ready
add slidingwindow and ops for gpt_oss
replace FIA with FIA_v2

545e856971 [Refactor]3/N Refactor mla_v1.py & extract mla_cp (#4933)
RFC: https://github.com/vllm-project/vllm-ascend/issues/4629
Reason:
The functions related to Cp differ significantly from those of normal
MLA-Attention, but the coupling is quite severe.

Steps:
Isolate PCP and DCP
(1) create a new python file: mla_cp.py
(2) add classes AscendMlaCPImpl and
AscendMlaCPMetadataBuilder,Inheritance AscendMLAImpl and
AscendMLAMetadataBuilder
(3) Remove PCP and DCP-related methods from mla_v1.py to mla_cp.py

fd7c929145 [perf] replace all_reduce for kv_consumer and support different num_tokens among all ranks (#4983)
pick from https://github.com/vllm-project/vllm-ascend/pull/4736 to fix
the merge conflict

### What this PR does / why we need it?
Currently, the all_reduce operation in _sync_metadata_across_dp is
performed with gloo backend which is extremely time-consuming when
DPEngineCores are in different nodes. This operation cannot be ignored
by async scheduling in multi-node-scenarios with speculative decoding
(e.g., EAGLE, mtp).

This pr eliminates the all_reduce operation for D Nodes and change the
input parameter of MoEDispatch & MoeCombine operators to make MC2EP
support different num_tokens across all ranks.

### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Tested with PD disaggregation (2P: DP2TP8EP16 1D: DP8TP4EP32) scenarios
while enabling async scheduling. This pr can remove cross-node
all_reduce with gloo backend and further reduce latency with correct
accuracy.

0fbe0831ec [bugfix][refactor] fix recompute_scheduler break with vllm 0.12.0 & support async scheduling & refactor recompute_scheduler.py (#4895)
### What this PR does / why we need it?
Currently, the initialization and fundamental functions of
RecomputeScheduler are broken with `vLLM v0.12.0`. This PR fixes the
conflicts of `RecomputeScheduler` and refactor its implementations by
inheriting original `Scheduler` of vLLM. Meanwhile, this PR also
supports async cheduling with recompute scheduler by implementing
`AsyncRecomputeScheduler` which is simply inherited `AsncyScheduler` of
vLLM and `RecomputeScheduler` of vLLM-Ascend with python MRO.
### Does this PR introduce _any_ user-facing change?
No. The switch naming is the same as v0.11.0 :
`recompute_scheduler_enable`
### How was this patch tested?
E2E serving with 2P1D dsv3.1 passed. The performance was the same as
original vllm scheduler with `async_scheduling` and preempted requests
in D Nodes are successfully transfered to Proxy and further to P Node.
This significantly improves the performance and robustness of PD
disaggregation deployments.

332b547728 [Bugfix] support mtp kv transfer and pp partition by hand in kv transfer (#4892)
### What this PR does / why we need it?
Current mooncake connector has following problems with PP and MTP
enabled:
1. MTP layer kv caches are not transfered, it may cause decreasing of
accept ratio: This PR add MTP layer indices for last PP stage after
calculating end_layer in transfer_kv_cache
2. While MTP enabled, PP layers divided by default may cause imbalance
between stages, we need to use `VLLM_PP_LAYER_PARTITION` environment to
make it balance by hand, but in mooncake connector kv transfer, decode
doesn't know the partition of prefill node: This PR add config
`pp_layer_partition` in `kv_connector_extra_config` to make decode node
acquire the partition information of prefill node.

### Does this PR introduce _any_ user-facing change?
When prefill using `VLLM_PP_LAYER_PARTITION` environment, add
`pp_layer_partition` in `kv_connector_extra_config` like below:
```
export VLLM_PP_LAYER_PARTITION=33,28
"kv_connector_extra_config": {
    "use_ascend_direct": true,
    "prefill": {
            "dp_size": 1,
            "tp_size": 8,
            "pp_size": 2,
            "pp_layer_partition": "33,28"
     },
     "decode": {
            "dp_size": 16,
            "tp_size": 1,
            "pp_size": 1
     }
}

eac72f5f23 [Feat] Flashcomm2 use o_shared linear (#4188)
### What this PR does / why we need it?

It is mentioned in the [flashcomm2 technical
report](https://gitcode.com/ascend-tribe/ascend-inference-cluster/blob/main/FlashComm/FlashComm2%E5%A4%A7%E6%A8%A1%E5%9E%8B%E6%8E%A8%E7%90%86%E4%B8%AD%E4%BB%A5%E5%AD%98%E6%8D%A2%E4%BC%A0%E7%9A%84%E9%80%9A%E4%BF%A1%E4%BC%98%E5%8C%96%E6%8A%80%E6%9C%AF.pdf)
that FC2 will introduce full redundant storage of the o_proj matrix,
which will put pressure on the memory. Therefore, the technical report
proposed a compromise solution using otp2, but it will introduce
additional reduce-scatter communication.

We propose a shared linear feature (#2931 ) that supports distributing
weights layer by layer to each card, avoiding the need for TP splitting,
and can solve the memory issue.

This PR depends on #3232 and #2931
