+"""Suite-level hardware gate for the tirx tests.
+
+The tirx kernels and codegen paths target Blackwell (sm_100a) — they emit
+PTX/SASS (tcgen05, tmem, cp.async ``.async`` modifiers, fp8 conversions, ...)
+that ptxas/NVRTC reject for older targets, and many tests execute on the
+device. Running the suite on a CPU-only node or a pre-sm_100 GPU therefore
+fails at compile/run time rather than skipping. Gate the whole directory on a
+real sm_100a device so it skips cleanly where the hardware is absent and runs
+in full where it is present.
