Summary
Follow-up to #20271.
test_ptx_tcgen05_mma_block_scale_collector_a_without_block_sizecertifies a collector-qualifiedtcgen05.mmablock-scale form, which is a PTX ISA 9.4 form and therefore needs nvcc / ptxas 13.4 or newer. This gates the test withenv.has_nvcc_version(13, 4), the same guard the other 9.4-only certifications intests/python/tirx/codegen/test_ptx_dialect.pyalready use, so older toolchains skip it instead of failing in ptxas.Test-only change; no table or codegen edits.
