ply is a light-weight dynamic tracer for Linux that leverages the kernel's BPF VM in concert with kprobes/tracepoints to attach probes to arbitrary points in the kernel. Most tracers that generate BPF bytecode are based on the LLVM-based BCC toolchain; ply on the other hand has no external dependencies outside libc, making it suitable for use on constrained embedded systems. Currently ply supports x86_64, aarch64, arm, riscv64, riscv32, powerpc, mips(el), and mips64(el) architectures. Further documentation, examples and implementation details may be found at: https://github.com/iovisor/ply. Signed-off-by: Tony Ambardar <itugrok@yahoo.com>

Testing: Repeatedly build and run-tested in the past against
openwrt/master, usingqemu/x86_64,qemu/armvirt[32|64],malta/mips32be, and most recently withmalta/mips64el, with kernels ranging from 5.15 to 6.6.CC: @zhaojh329 This is the package I've been using for a few years. Comments or improvements welcome!
This is intended to complement
packages/devel/perfin the main repo.
