…to ILP kernel

Two related changes to flashinfer/gdn_kernels/gdn_decode_bf16_state.py and
the T=1 dispatch in flashinfer/gdn_decode.py:

1) Per-call Python overhead fix
   Move torch.arange / torch.empty / from_dlpack / get_device_capability out
   of the steady-state call path. These were previously called on every
   invocation of gated_delta_rule and gated_delta_rule_mtp, adding ~3.75 us
   of CUPTI-visible overhead per call at small BS. All default-tensor
   allocation and dlpack conversion is now done once, inside the
   `cache_key not in _compiled_kernels_*` block, and cached alongside the
   compiled kernel. Steady-state calls pass raw torch tensors directly to
   the tvm-ffi callable. Adds module-level _USE_PACKED_FMA in place of
   per-call torch.cuda.get_device_capability().

2) Pool + padding support on the ILP kernel
   gdn_decode_bf16state_ilp_kernel (the T=1 fast path for B >= 16) now
   accepts h0_indices and h0_out_indices, matching the MTP kernel's
   signature. Negative indices redirect to pool slot 0 (null buffer);
   writes go to a separate flat_write_idx so input and output pool slots
   can differ. The ILP launcher and gated_delta_rule wrapper thread the
   new tensors through; the T=1 dispatch in flashinfer/gdn_decode.py is
   collapsed so pool+indices T=1 calls no longer detour through the
   heavier MTP kernel.

Design choice: kernel always takes indices (no constexpr switch).

…stic fix

Three coordinated changes to the BF16 GDN MTP decode path on B200:

1. New kernel `gated_delta_rule_mtp_wide_vec`
   (flashinfer/gdn_kernels/gdn_decode_bf16_state_wide_vec.py):
   - 128 threads/CTA organised as 8 groups of 16 threads (baseline: 4 of 32)
   - vec=8 BF16 per thread -> LDG.128 / STG.128 (baseline: vec=4 -> .64)
   - ILP=4 V-rows/thread, 4-stage butterfly over 16-lane subgroup
   - No TMA, no persistent CTAs; the win is purely wider LSU transactions
   - Peaks at 77.6 % DRAM SOL at B=256, T=2, HV=64

2. Auto-dispatcher inside `gated_delta_rule_mtp`
   (flashinfer/gdn_kernels/gdn_decode_bf16_state.py):
   - New module-level `_WIDE_VEC_WORK_UNITS_THRESHOLD = 1024`
   - Routes to wide_vec when `B*HV >= 1024 and T >= 2 and K == V == 128`
   - T=1 and small-batch callers keep the existing baseline path verbatim,
     so the public API is source-and-ABI compatible.

3. B=4 HV=64 T=2 heuristic fix in `_get_bf16_mtp_config`:
   - Baseline's T=2 code path (gdn_decode_bf16_state.py) recomputes g/beta
     inline instead of reading from sGB (only T>2 pre-populates sGB). The
     inline softplus+exp+log+sigmoid stalls the ILP=8 pipeline at small
     work_units.
   - Fix: when `seq_len == 2 and work_units <= 256`, return (tile_v, 4)
     instead of (tile_v, 8). ILP=4 gives ~62 % occupancy vs ILP=8's ~37 %,
     covering the recompute latency.
   - Measured: B=4 HV=64 T=2: 11.20 us -> 9.63 us (1.17x).

(B200, HV=64, H_Q=H_K=16, K=V=128, BF16, cache_intermediate=True,

After rebasing the wide_vec dispatcher onto bf16_baseline_fix, the original
T=1 / T=2 small-batch heuristic from 192fa39 / 7b7f1ac regressed because
the _get_bf16_mtp_config helper was dropped in the conflict resolution
(upstream only had _select_tile_v_for_mtp for ILP=8 tile sizing). This
commit re-adds the ILP=4 variant so the PR ships without the B=4 T=2
regression that would otherwise show in CI.

Changes to flashinfer/gdn_kernels/gdn_decode_bf16_state.py:

1. New @cute.kernel gdn_decode_bf16state_mtp_ilp4_kernel. Same math as the
   ILP=8 kernel, but processes 4 V-rows/group/iter instead of 8.
   - ILP=4: ~48 regs/thread -> ~62 % occupancy (vs ILP=8's ~37 %)
   - Minimal signature: single h0_indices (read == write). Split-pool writes
     are delegated to ILP=8 by the dispatcher; the ILP=4 path never needs
     h0_out_indices, so we skip the extra plumbing.

2. New @cute.jit run_gdn_decode_bf16state_mtp_ilp4 launcher, mirrors the
   existing ILP=8 launcher's tile_v/grid/SMEM computation but calls the
   new kernel.

3. New _get_bf16_mtp_config(batch_size, seq_len, num_v_heads, v_dim) helper:
     - work_units <= 128: (min(16, v_dim), 4)  # B<=2 at HV=64
     - seq_len == 2 and work_units <= 256: (tile_v, 4)  # covers B=4 HV=64
     - else: (tile_v, 8)
   The T=2 branch compensates for the ILP=8 pipeline stall from the inline
   g/beta recompute path (sGB is only populated for T > 2 in the ILP=8
   kernel; at small work_units ILP=8's 37 % occupancy cannot hide the
   softplus+exp+log+sigmoid latency).

4. gated_delta_rule_mtp dispatcher:
     - When output_state_indices is None: pick (tile_v, ilp_rows) via
       _get_bf16_mtp_config and route to the matching launcher.
     - When output_state_indices is not None: force ilp_rows=8 so the
       split-pool write path (h0_out_indices) stays on the ILP=8 kernel
       that supports it.
     - Cache key now includes ilp_rows so the two launchers don't collide.

Perf verification (B200, HV=64, H_Q=H_K=16, K=V=128, BF16, CUPTI,
5 warmup + 50 bench iters; cache_intermediate=True, disable_state_update=True

Correctness: 30 / 30 test_gdn_decode_bf16_state_mtp_kernel configs pass at
B in {1, 2, 4, 8, 16}, T in {2, 4, 8}, cache_intermediate in {T, F} via
the official _test_gdn_decode_bf16_state_mtp_kernel helper. No test changes
needed — the existing test exercises the dispatcher and both ILP paths.

Follow-up to PR flashinfer-ai#3127. The shipped wide_vec kernel has a fixed tile_v=128
so its grid is only B*HV CTAs — at B <= 8 (HV=64) that's <= 512 CTAs on a
148-SM B200 (< 3.5 waves), and the dispatcher falls back to the baseline
ILP=4/8 path (LDG.E.64). This commit parameterizes tile_v so the grid gains
a V-tile dimension, letting the wide_vec kernel (LDG.E.128 on H) reach down
into small-batch sizes that were previously starved of SM parallelism.

Changes:

1. gdn_decode_bf16_state_wide_vec.py — tile_v is now a per-call constexpr:
   - Kernel decodes (i_n, i_hv, i_v) from block_idx; v_base offset by
     `i_v * tile_v`. ROWS_PER_GROUP and ITERS_PER_GROUP promoted from
     module-level constants to per-kernel constexprs.
   - Launcher computes grid = B * HV * (V / tile_v) and passes tile_v +
     num_v_tiles to the kernel.
   - Public wrapper `gated_delta_rule_mtp_wide_vec` accepts `tile_v: int = 128`
     (keyword-only default; positional callers unchanged).
   - Valid tile_v values: {32, 64, 128}. Asserted at the launcher entry.
   - Subgroup layout unchanged (16 threads x 8 BF16 per thread = LDG.E.128),
     so every tile_v variant uses the same per-thread memory-op widths.
   - Bit-exact with the previous fixed-tile_v=128 kernel at tile_v=128
     (verified: max_abs_diff = 0.0 over 252 pytest configs).

2. gdn_decode_bf16_state.py — new `_select_wide_vec_tile_v(B, HV, V=128)`
   helper picks tile_v by work_units = B * HV:
     work_units >= 1024 -> tile_v = 128  (unchanged: B >= 16 at HV=64)
     work_units >=  512 -> tile_v =  64  (new:   B =  8 at HV=64)

   `_WIDE_VEC_WORK_UNITS_THRESHOLD` lowered 1024 -> 128 (module-scope
   constant kept for external benchmarks that monkey-patch it; actual
   dispatch uses the new picker). Dispatcher in `gated_delta_rule_mtp`
   now calls the picker and passes tile_v into `gated_delta_rule_mtp_wide_vec`.

Biggest headline: B=4 T=2 goes from 9.63 us to 8.14 us (1.18x) by routing to
wide_vec tile_v=32, which was previously dispatched to the baseline ILP=4
kernel. Cumulative against origin/main at B=4 T=2: 11.14 us -> 8.14 us = 1.37x.

Correctness: 378 / 378 new pytest configs pass
(test_gdn_decode_bf16_state_wide_vec_mtp_kernel). Equivalent 1008-config
sanity run across tile_v = {32, 64, 128} x HV = {32, 64} also passed
during development (not in CI to keep the default matrix size reasonable).

Code Review

This pull request enhances the GDN decode implementation by adding support for pool-based state management with separate input and output indices and introducing two new kernel variants: an ILP=4 MTP kernel for small batches and a wide-vector MTP kernel for large work units. Feedback primarily targets the wide-vector implementation, highlighting the need to maintain consistent in-place state updates when caching is enabled and to align the function's return type with the existing production API. Additionally, suggestions were made to optimize shared memory allocation and improve global memory throughput by vectorizing scalar loads and stores.

Skipping the final state write-back when cache_intermediate_states is enabled breaks consistency with other kernels and the expected behavior of in-place state updates. The initial_state_source should always be updated if disable_state_update is False, regardless of whether intermediate states are being cached.

The return type of gated_delta_rule_mtp_wide_vec should be Tuple[torch.Tensor, torch.Tensor] to match the production gated_delta_rule_mtp API and ensure the state is correctly returned to the caller.

Forcing effective_disable_final = True when caching is enabled prevents the in-place update of the initial state tensor. This should be removed to maintain consistent behavior across all GDN kernels.

effective_disable_final = True
effective_disable_final = disable_state_update

The sGB tensor is allocated with 3 columns, but the third column (used for kq_partial) is never read in the compute loop. Reducing the allocation to (T, 2) would save shared memory.

These scalar loads from global memory are performed by all threads in a group, resulting in inefficient broadcast loads. Using cute.autovec_copy to load into a register tensor once per group would be more efficient.

These scalar stores can be improved by using a vectorized store via cute.autovec_copy with a 4-element register tensor.
