Code Review

This pull request introduces support for TileLang CUDA kernels, which involves substantial modifications to the CMake build configuration and the CUDA Dockerfile to handle new dependencies like TVM and TileLang. Additionally, new integration tests have been added to validate the FlashInfer and TileLang kernel functionality. My review identified two critical issues: one in the Dockerfile where the LD_LIBRARY_PATH is incorrectly overwritten, and another in a new test file that contains a hardcoded, user-specific absolute path, which compromises test portability.

[gemini-code-assist]

The LD_LIBRARY_PATH is being overwritten. The ENV instruction on line 223 replaces the value set on line 222, which means the path /usr/local/tilelang/lib will be missing from the final LD_LIBRARY_PATH. This will likely cause runtime errors as libraries from TileLang will not be found. To fix this, you should combine them into a single ENV instruction to correctly prepend both paths.

ENV LD_LIBRARY_PATH=/usr/local/tilelang/lib:/usr/local/lib:$LD_LIBRARY_PATH

[gemini-code-assist]

This test includes a hardcoded absolute path (/export/home/wangyifan/...) as a fallback. This makes the test non-portable, as it will fail on any machine other than the original author's or in any CI environment. The test should instead be skipped if the required TILELANG_TMA_KERNEL_SO_PATH environment variable is not set.

Suggested change

	const char* so_env = std::getenv("TILELANG_TMA_KERNEL_SO_PATH");
	const std::string so_path =
	(so_env != nullptr && std::string(so_env).size() > 0)
	? std::string(so_env)
	: "/export/home/wangyifan/tmp/tilelang/test_tilelang/kernels/"
	"simple_matmul.so";
	const char* so_env = std::getenv("TILELANG_TMA_KERNEL_SO_PATH");
	if (!so_env || !*so_env) {
	GTEST_SKIP() << "TILELANG_TMA_KERNEL_SO_PATH is not set, skipping TMA matmul test.";
	}
	const std::string so_path(so_env);
