[Bug]: CK WMMA kernels fail on gfx1150 — amd_wmma.hpp missing from gfx115x enablement

[Peterc3-dev]

Description

CK WMMA kernels crash at runtime on gfx1150 (Ryzen AI 9 HX 370, Radeon 890M, RDNA 3.5 Strix Point):

hip_code_object.cpp:400: StatCO::getStatFunc: Assertion 'err == hipSuccess' failed

Root Cause

PR #2065 added gfx115x compile-time support to ck.hpp, device_prop.hpp, and ck_tile/core/config.hpp, but missed include/ck/utility/amd_wmma.hpp.

In ROCm 7.2.x, amd_wmma.hpp lines 12-14:

#if defined(__gfx1100__) || defined(__gfx1101__) || defined(__gfx1102__) || \
    defined(__gfx1103__) || defined(__gfx11_generic__)
#define __gfx11__

gfx1150/1151/1152 are missing. All __builtin_amdgcn_wmma_* intrinsics are gated on __gfx11__, so they compile to no-ops (the else branch assigns to ignore). When MIOpen selects a CK WMMA solver based on is_gfx11_supported() (which correctly returns true from ck.hpp), the kernel contains no WMMA instructions and the code object fails to load.

The Fix Already Exists on develop

On develop, amd_wmma.hpp correctly includes gfx115x:

#if defined(__gfx1100__) || defined(__gfx1101__) || defined(__gfx1102__) || \
    defined(__gfx1103__) || defined(__gfx1150__) || defined(__gfx1151__) || \
    defined(__gfx1152__) || defined(__gfx1153__) || defined(__gfx11_generic__)
#define __gfx11__

Request: Backport this fix to release/rocm-rel-7.2.

Reproduction

1. Build CK with -DGPU_TARGETS=gfx1150 on ROCm 7.2.0
2. Run any WMMA-based kernel (e.g., MIOpen CK convolution solver)
3. Observe StatCO::getStatFunc assertion failure

Environment

• Hardware: AMD Ryzen AI 9 HX 370, Radeon 890M (gfx1150)
• OS: CachyOS, kernel 6.19.5
• ROCm: 7.2.0
• MIOpen: Built from amd-develop with gfx1150 in legacy CK whitelist
