+Subject: [PATCH] exclude torch-c-dlpack-ext from the riscv64 dependency set
+
+Upstream-Status: Inappropriate [riscv64 CI-specific: drops a torch C-extension accelerator with no riscv64 wheel anywhere; not something upstream would want for its general audience]
+
+torch-c-dlpack-ext is an unconditional dependency for python_version <
+'3.14', but it ships no riscv64 wheel on PyPI or pypi.riseproject.dev, so
+`pip install` of the riscv64 wheel fails to resolve on any interpreter
+below 3.14. Upstream's own comment above the dependency says it is a soft
+accelerator, not a hard requirement: "Without it, TVM FFI may require JIT
+compilation on first import." Gate it off on riscv64 with an extra
+platform_machine marker so the rest of the dependency set (all of which do
+have riscv64 wheels) resolves normally; every other architecture keeps the
+exact same dependency.

+Subject: [PATCH] cap the cython build requirement below 3.3
+
+Upstream-Status: To upstream [not submitted: cannot open issues/PRs against tile-ai/tilelang from this environment; cross-platform bug, not riscv64-specific]
+
+build-system.requires pins "cython>=3.1.0" with no upper bound. Cython
+3.3.0 (Cython/Utility/ModuleSetupCode.c) added a hard #error when a
+Limited API build targets below Python 3.9:
+
+    #if Py_LIMITED_API < 0x03090000
+      #error "Cython 3.3 requires the Python Limited API version to be
+      3.9 or greater."
+
+tilelang's own scikit-build config sets `wheel.py-api = "cp38"`, so
+SKBUILD_SABI_VERSION is 3.8 and tilelang_cython_wrapper's generated
+.cpp fails to compile once an unbounded resolve picks up Cython
+3.3.0 (the current latest release on PyPI). This is not
+architecture-specific: any build resolving cython>=3.3 against the
+existing cp38 Limited API target breaks the same way. Cap it below
+3.3 so the resolver keeps picking a Cython release that predates this
+check, matching the Cython version tilelang's own CI has actually
+been built and tested against.
