+Subject: [PATCH 1/2] Add a linux-riscv64 platform
+
+Upstream-Status: To upstream [not yet submitted; python-wheels does not open issues/PRs on third-party repos]
+
+Build the same shared libraries natively on a riscv64 host, in a
+Rocky Linux 10 (glibc 2.39) container, the way linux-arm64 is built
+natively in a Rocky Linux 8 container. The platform files are the
+linux-arm64 ones with the RISC-V triplet, Rust host and -march=rv64gc
+baseline swapped in, and Rocky 10's own GCC 14 in place of
+gcc-toolset-15. The rv64gc baseline matches what lovell/sharp-libvips'
+linux-riscv64 platform uses.

+Subject: [PATCH 2/2] Build zlib-ng, libaom and pixman without RVV kernels
+
+Upstream-Status: Inappropriate [works around riscv64 hosts that advertise V but trap on RVV 1.0 code, as the python-wheels riscv64 runners do]
+
+zlib-ng, libaom and pixman each compile RVV 1.0 kernels whenever the
+compiler supports them and pick them at runtime from AT_HWCAP (or
+hwprobe). On hosts whose kernel reports V while the core only
+implements a pre-1.0 vector extension, the first vsetvli raises
+SIGILL, so the dispatch is not a safe guard there. Keep the rv64gc
+scalar paths instead; libaom's -DENABLE_RVV=0 is what
+lovell/sharp-libvips already passes for its linux-riscv64 build.
+
+zlib-ng 2.3.3 also needs WITH_RISCV_ZBC off: it defines RISCV_FEATURES
+only when RVV is enabled, so a Zbc-only build fails in functable.c on
+`cf.riscv` (fixed after 2.3.3 by zlib-ng/zlib-ng@9f396c3).

+
+Upstream-Status: To upstream [not yet submitted; python-wheels does not open issues/PRs on third-party repos]
+
+get_plat() asserts the platform is in SUPPORTED_PLATFORMS, so a
+riscv64 build fails before it downloads anything. Add linux-riscv64
+and map the riscv64 machine name to the libvips-packaging platform
+suffix, so the script resolves libvips-<version>-linux-riscv64.tar.gz
+the same way it resolves the other Linux tarballs.
