"""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.
