+# rocjitsu CI: build from source and run the full test suite.
+#
+# How it works:
+#   1. Sparse-checkout emulation/rocjitsu
+#   2. Install ROCm from the AMD apt repo (provides hipcc and device
+#      libraries for compiling HIP test kernels). See
+#      https://github.com/ROCm/rocm-systems/pull/6479 for an
+#      alternative using pip rocm-sdk-core (TheRock).
+#   3. Build with clang + ninja in Release mode
+#   4. Run the full ctest suite on the CPU emulator
+#
+# No GPU hardware is needed. rocjitsu's tests run on its built-in
+# CPU emulator, which simulates AMD GPU execution. HIP kernels are
+# compiled for gfx950 by hipcc, then loaded and executed by the
+# emulator at test time.
+#
+# Excluded tests:
+#   RocminfoTest — spawns rocminfo under LD_PRELOAD with the KMD
+#   interposer, which requires /dev/kfd (unavailable on CI runners).
