Friday Ortiz	ab38afe95d	perf_event: 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. Co-authored-by: Tamir Duberstein <tamird@gmail.com>	1 week ago

Tamir Duberstein	d1457acc6d	ci: cache downloads ... We're seeing 429 from Github trying to download gen_init_cpio, so cache it using actions cache. Since I'm here add this for kernel images as well to save time waiting on slow Debian servers.	11 months ago
