+From: RISE Project CI <ci@riseproject.dev>
+Date: Thu, 10 Jul 2026 00:00:00 +0000
+Subject: [PATCH 1/2] [CI] Add manywheel Dockerfile for riscv64
+
+Add Dockerfile_2_39_riscv64 for building riscv64 manywheel images using
+quay.io/pypa/manylinux_2_39_riscv64 as base, and register the new
+manylinux2_39_riscv64-builder:cpu-riscv64 image in build.sh.
+
+Pin OPENBLAS_VERSION to v0.3.34: v0.3.33 (install_openblas.sh's default)
+fails to build on riscv64 with "'coremsg' undeclared" in
+dynamic_riscv64.c; v0.3.34 declares that buffer. Set as a plain shell
+variable (not folded into DOCKER_GPU_BUILD_ARG) since build.sh
+unconditionally appends its own `--build-arg "OPENBLAS_VERSION=..."`
+after DOCKER_GPU_BUILD_ARG on the docker build command line, and a
+later --build-arg for the same key silently wins.
+
+Upstream-Status: To upstream
