Summary
This PR removes the
linux/ppc64letarget from the multi-architecture Docker build matrix.Reason
The
ppc64le(PowerPC 64-bit Little Endian) architecture requires buildingpydantic-corefrom source using Rust.Due to missing musl development headers and incomplete Rust support for
powerpc64le-unknown-linux-musl, the build process consistently fails on Alpine Linux.Even when fixed locally, QEMU emulation causes excessive build times (20+ minutes) during CI runs on GitHub Actions.
Since the project does not actively target IBM Power or OpenPOWER environments, maintaining this architecture provides no practical benefit and significantly slows down CI builds.
Changes
linux/ppc64lefrom the Docker build matrixamd64,arm64) remain supportedNotes
If PowerPC support is ever required in the future, it can be reintroduced using a native ppc64le runner with preinstalled Rust and musl toolchain support instead of QEMU-based emulation.
