# Build kernels as a static archive (.a) instead of shared library (.so).
# When enabled, the kernel code is embedded directly into the consuming crate,
# eliminating the runtime dependency on libkvbm_kernels.so.
# Note: This only affects real CUDA builds; stubs always remain dynamic.

# Enable CUDA tests - only works when real CUDA kernels are built (not stubs)
# Tests are gated with #[cfg(all(test, feature = "testing-cuda", not(stub_kernels)))]

# Enable operational_copy, universal_from_block, block_from_universal kernels.
# These kernels perform data layout permutation and are only needed for
# non-standard transfer paths. The default vectorized_copy kernel handles
# most FC↔LW transfers efficiently without permutation.
