New Features

• Added MIPS bindings Updated aya-obj/src/generated/mod.rs and `bpf/aya-bpf-bindings/src/lib.rs to use the mips bindings.

Other

• support hardware breakpoints Implement PerfEventConfig::Breakpoint, allowing users to attach hardware breakpoints. Generate HW_BREAKPOINT_* and struct bpf_perf_event_data in support of this feature and update the type of PerfEventContext accordingly.

  Add a test exercising R, W, RW, and X breakpoints. Note that R breakpoints are unsupported on x86, and this is asserted in the test.

  Extend the VM integration test harness and supporting infrastructure (e.g. download_kernel_images.sh) to download kernel debug packages and mount System.map in initramfs. This is needed (at least) on the aarch 6.1 Debian kernel which was not compiled with CONFIG_KALLSYMS_ALL=y for some reason, and the locations of globals are not available in kallsyms. To attach breakpoints to these symbols in the test pipeline, we need to read them from System.map and apply the KASLR offset to get their real address. The System.map file is not provided in the kernel package by default, so we need to extract it from the corresponding debug package. The KASLR offset is computed using gunzip which appears in kallsyms on all Debian kernels tested.

• extract CARGO_CFG_BPF_TARGET_ARCH logic

• run clippy with target=bpf This build warnings from integration tests and makes aya-ebpf's build script stricter.

• reorder-keys Group non-workspace keys before workspace ones for readability.

• hook up loongarch64 This causes rustfmt to format those files.

  Squish some other conditional compilation to get rustfmt sorting.

• do not attempt to run rustfmt This can be done externally. Do so in CI.

  This is an attempt to resolve the inconsistency between CI and local rustfmt in the generated bindings.

  Restore running CI on generated branches; the presence of a PR is apparently not enough.

• tidy up Move some code out of a loop, where it appears to be nonsense.

• add archs powerpc64 and s390x to aya bpfman, a project using aya, has a requirement to support powerpc64 and s390x architectures. Adding these two architectures to aya.
