This PR aims to update `target_probs` to `target_logits` in
`rejection_sample`, for catching up with
https://github.com/vllm-project/vllm/pull/32852. Otherwise, sampling

### What this PR does / why we need it?
This PR extends original `rope_triton_forward` and
`split_qkv_rmsnorm_rope` to support `cos_sin_cache` && `positions` as
inputs. This fully aligns to vLLM RoPE api interface. Compared with
earlier implementation for RoPE, the benefits are:
1. avoiding pre-computation of `cos` `sin` before model execution, which
helps to remove redundant codes.
2. allowing eagle3 draft model to have different rope parameters with
main model (see #6612 ). This help to recover accept rate && accuracy in
that case.
In addition, this kernel change only introduces very small performance
degradation. Those `index_select` or `chunk` operations are now changed
into simple memory access in triton kernel (For example,
https://github.com/vllm-project/vllm-ascend/pull/5450/changes#diff-a4c2d3071530df193b98f9bf38553874bc4d47571336711f116c26d019cfbb6aR77-R81).
**Highlights**
- **RoPE Cache Unification**: Replaced separate _sin and _cos global
tensors with a unified cos_sin_cache and explicit positions tensor for
Rotary Positional Embeddings (RoPE), streamlining data handling.
- **Triton Kernel Integration**: Updated Triton kernels
(split_qkv_rmsnorm_rope_kernel, _triton_rope) to directly consume the
cos_sin_cache and positions for more efficient and integrated RoPE
calculations.
- **Custom Operation Registration**: Registered `rope_forward_oot` as a
new custom operation, allowing its use in fused compilation passes and
providing a dedicated entry point for the new RoPE implementation.
- **Refactored RoPE Forward Pass**: Modified the rope_forward_oot
function to accept the new cos_sin_cache and positions arguments,
enabling a more flexible and integrated RoPE application within the
system.

- Adding a unified MLP implementation (`unified_apply_mlp`) for 310P
that handles both quantized and unquantized paths.
- Refactoring the MoE and quantization configuration logic to correctly
route to the new 310P-specific implementations.
- Adding new e2e and unit tests to verify the functionality of MoE W8A8
quantization.

#### Deepseek v3.1 chat
Of course! Here is a comprehensive explanation of deep learning, broken
down for clarity.\n\n### The Simple Analogy: A Child Learning to
Recognize a Cat\n\nImagine teaching a child what a cat is. You don't
give them a rulebook with instructions like \"has pointy ears, whiskers,
and a tail.\" Instead, you show them many pictures, saying \"this is a
cat\" or \"this is not a cat.\" The child's brain gradually learns to
identify the complex patterns—the combination of shapes, colors, and
textures—that define \"cat-ness.\"\n\n**Deep learning is essentially
this, but for computers.** It's a method for teaching computers to learn
from examples and recognize patterns directly from data (like images,
sound, or text) without being explicitly programmed with rigid
rules.\n\n---\n\n### The Technical Definition\n\n**Deep Learning is a
subfield of machine learning, which itself is a subfield of artificial
intelligence (AI).** It uses artificial **neural networks** with many
layers (\"deep\" networks) to model and understand complex patterns in
data.\n\nHere are the key concepts in that definition:\n\n1.
**Artificial Intelligence (AI):** The broad science of making machines
smart and capable of performing tasks that typically require human
intelligence.\n2. **Machine Learning (ML):** A subset of AI that gives
computers the ability to learn from data *without* being explicitly
programmed for every single rule.\n3. **Deep Learning (DL):** A

### What this PR does / why we need it?
This PR refactors the tutorial documentation by restructuring it into
three categories: Models, Features, and Hardware. This improves the
organization and navigation of the tutorials, making it easier for users
to find relevant information.
- The single `tutorials/index.md` is split into three separate index
files:
- `docs/source/tutorials/models/index.md`
- `docs/source/tutorials/features/index.md`
- `docs/source/tutorials/hardwares/index.md`
- Existing tutorial markdown files have been moved into their respective
new subdirectories (`models/`, `features/`, `hardwares/`).
- The main `index.md` has been updated to link to these new tutorial
sections.
This change makes the documentation structure more logical and scalable
for future additions.
### Does this PR introduce _any_ user-facing change?
Yes, this PR changes the structure and URLs of the tutorial
documentation pages. Users following old links to tutorials will
encounter broken links. It is recommended to set up redirects if the
documentation framework supports them.
### How was this patch tested?
These are documentation-only changes. The documentation should be built
and reviewed locally to ensure all links are correct and the pages
render as expected.

### What this PR does / why we need it?
This PR fixes an `AttributeError: 'Parameter' object has no attribute

The error is caused by a monkey-patch on
`MLAAttention.process_weights_after_loading` which is incompatible with
changes in vLLM v0.15.0. This is likely related to PyTorch's deprecation
of the `.data` attribute on `torch.nn.Parameter` objects.

vLLM v0.15.0 and newer versions, resolving the crash.

### What this PR does / why we need it?
For deepseek v3.2, DSA use FullAttentionSpec, allocate 2 * mla page size
bytes, and we use half of that for k cache in DSA
However, the actual proportion of k cache is not high, which results in
a large amount of kvcache being wasted. The proportion of discarded
kvcache is (576-128)/(576 x 2) = 0.388.
Run the same script to start DeepSeek V3.2 on a single A3 server. The
following shows the comparison of kvcache usage:
Before refactoring
```
[kv_cache_utils.py:1307] GPU KV cache size: 15,872 tokens
```
After refactoring
```
[kv_cache_utils.py:1307] GPU KV cache size: 25,984 tokens
```
This pull request refactors the KV cache allocation for Deepseek v3.2
models that use sparse attention. It replaces the use of
`FullAttentionSpec` with `MLAAttentionSpec` and introduces a more
principled way of calculating KV cache tensor split factors based on
model configuration.
This change removes hardcoded values and correctly sizes the cache
tensors, leading to optimized memory usage and improved code
maintainability.

user-facing changes.

### What this PR does / why we need it?
This PR adds DCP support to the SFA backend.
Please note that due to operator constraints, the current implementation
has to all-gather the entire KV cache and modify the block table to
satisfy the operator input requirements. This results in significantly
increased communication overhead and peak memory usage. Therefore, this
is only a temporary workaround and will be refactored once the operator
provides proper support.
Additionally, because of the above limitations,
`cp_kv_cache_interleave_size` is currently required to be equal to
`block_size`. This restriction will also be removed after the refactor.

This PR addresses an issue where models using partial rotary position

### What this PR does / why we need it?
This PR fixes a bug in the `test_triton_fusion_ops` test case. The test
compares a fused kernel (`fused_sigmoid_gating_delta_rule_update`) with
a split implementation. Both paths use a recurrent state tensor.
The bug was that the state tensor was being modified in-place by the
fused kernel call, and this modified tensor was then reused for the
split implementation path. This led to an incorrect comparison and test
failure.
This fix ensures that each path starts with an identical, clean initial
state by creating separate tensors. It also changes the state
initialization from `torch.randn` to `torch.ones` to make the test
deterministic.
### Does this PR introduce _any_ user-facing change?
No, this change only affects a test case and has no user-facing impact.
### How was this patch tested?
The fix is applied directly to the test case. The CI passing for
`test_fused_sigmoid_gating_delta_rule.py` will confirm that the fix is
working as expected.

### What this PR does / why we need it?
This PR focuses on performance optimization for the DispatchFFNCombine
operator. The key optimizations include:
1. Improving communication efficiency by merging the transmission of
tokens and scales;
2. Decoupling multi-core dependencies and reducing waiting bubbles in
the combine process through tile-granularity communication;
3. Optimizing the full-card synchronization overhead before the
umpermute operation.
These optimizations aim to reduce the overall execution latency of the
DispatchFFNCombine operator and enhance the runtime performance of the
model inference process on Ascend devices.
### Does this PR introduce _any_ user-facing change?
No. This PR only involves internal performance optimization of the
DispatchFFNCombine operator and does not introduce any changes to
user-facing APIs, interfaces, or behaviors.
### How was this patch tested?
1. Enable the DispatchFFNCombine operator by setting the environment
variable:
```
export VLLM_ASCEND_ENABLE_FUSED_MC2=1
```
2. Run the standard model inference test suite with the above
environment variable enabled;
4. Verify the correctness of model outputs (ensuring no functional
regression) and measure the performance improvement of the
DispatchFFNCombine operator (reduced latency and improved throughput).

This PR removes the custom `rotary_embedding` operator and its
associated C++ kernel implementation, PyTorch bindings, and tests.
The codebase now falls back to using the native
`torch_npu._npu_rotary_embedding` implementation. This change simplifies
the codebase by removing custom, platform-specific kernel code and
relying on the standard NPU library implementation, which is presumably
more optimized and easier to maintain.

### What this PR does / why we need it?
This pull request integrates comprehensive support for Mixture of
Experts (MoE) models on the Ascend 310P device within the vllm-ascend
framework. It achieves this by introducing specialized modules for
expert selection, fused MoE layers, and optimized all-gather
communication. The changes also refine existing NPU operations, making
them more consistent and efficient for 310P, ultimately enhancing the
performance and compatibility of MoE models on this hardware.
Highlights
310P MoE Support: Introduces dedicated implementations for Mixture of
Experts (MoE) models on Ascend 310P devices, including new modules for
expert selection, fused MoE layers, and communication.
All-Gather Communication: Enforces the use of ALLGATHER communication
for MoE operations on 310P, optimizing data transfer and leveraging
NPU-specific token dispatching.
Simplified NPU Operations: Removes conditional type casting for
npu_swiglu and enables custom rotary embedding kernels unconditionally,
suggesting improved native support for 310P.
New MoE Classes Registered: Registers AscendFusedMoE310 and
AscendSharedFusedMoE310 to integrate 310P-specific MoE layers into the
system's custom operation registry.

### What this PR does / why we need it?
Fix the incorrect use of the `output` parameter in
`_forward_fia_slidingwindow`:
```
# Original (incorrect)
output, _ = torch_npu.npu_fused_infer_attention_score(...)
output= output.view(batch_size, self.num_heads, self.head_size)
```
In the original writing, the `output `parameter was directly assigned a
new value, which is inconsistent with the interface definition,
resulting in the inability to directly update `output `when calling
externally.
```
attn_output, _ = torch_npu.npu_fused_infer_attention_score(...)
attn_output = attn_output.view(batch_size, self.num_heads, self.head_size)
output[:batch_size] = attn_output[:batch_size]
```
### Does this PR introduce _any_ user-facing change?
