Description
This PR migrates Inkling FA4 attention warmup to the shared JIT warmup contract introduced in #47451,
and deprecates the legacy CuTeDSL warmup path(there is a conflict with the Kimi K3 integration #50089 that prevents this deprecation from being completed. It will be addressed in a future PR).See #49349 for more context
Motivation
enable_jit_warmupand run Inkling FA4 warmup throughkernel_warmup().What Changed
VllmJitKernelwrapper.Deprecated the legacy CuTeDSL warmup registry(there is a conflict with the Kimi K3 integration [Model] Add Kimi K3 support: model files and kernels [1/N] #50089 that prevents this deprecation from being completed. It will be addressed in a future PR)._trace_dispatch(...)with_whenpredicate support.zip_inputs(...)plus_when.AST Warmup Engine Update
_trace_dispatch(...)now accepts_when=<predicate>.This lets warmup definitions attach a small AST-traced predicate that filters generated dispatch points before they become compile keys. The predicate uses the same simple Python subset as
dispatch(...): local assignments, helper calls, arithmetic, comparisons, and boolean expressions.
