Subject: [PATCH] [mlir][spirv] Initial support for TOSA Extended Instruction
Set (001000.1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds initial support for the TOSA Extended Instruction Set
(001000.1) to the SPIR-V dialect in MLIR. The TOSA extended
instruction set provides a standardized set of machine learning
operations designed to be used within `spirv.ARM.Graph` operations
(corresponding to OpGraphARM in SPV_ARM_graph) and typed with
`!spirv.arm.tensor<...>` (corresponding to OpTypeTensorARM in
SPV_ARM_tensor).
The change introduces:
* Dialect plumbing for import, serialization, and deserialization of
the TOSA extended instruction set.
* The `spirv.Tosa.ArgMax` operation from TOSA extended instruction, each
lowering to the corresponding `OpExtInst`.
* Verification enforcing that `spirv.Tosa.ArgMax` appears only within
`spirv.ARM.Graph` regions, operates on `!spirv.arm.tensor<...>`
types, and is well-formed according to the TOSA 001000.1
specification.
Only the ArgMax operation from TOSA 001000.1 extended instructions is
introduced in order to show case the work needed: [arser, printer,
verifier, and round-trip tests using MLIR’s SPIR-V
serialization/deserialization infrastructure are included.
This work aligns with Khronos SPIR-V TOSA specifications.
Specification:
