What about python-bcc module ? Can you review this part ? BCC requires the linux kernel sources on the target to build bpf code or a 5.2 kernel with CONFIG_IKHEADERS (among other kernel options).

Sorry the quality is not as I'd like them to be. But this work was something I was doing on the side and wasn't keeping good track of it. I use buildroot root as my rootfs while testing and felt like having BCC and bpftrace would be nice, so started seeing what it takes to add them. I will improve the quality in the next submission and do things properly. > > + depends on BR2_PACKAGE_LLVM_BPF > > + select BR2_PACKAGE_ZLIB > > + select BR2_PACKAGE_TAR > > We identified some other dependencies (flex, audit, iperf3, netperf and xz). I do add host-flex dependency on bcc.mk. xz is unnecessary if we use tar (see below). audit, iperf3 and netperf dependencies do look strange to me. Certainly I didn't need them. Let me try to play with that. > I'm not sure about tar dependency. OK to select zlib, it seem we also need > BR2_PACKAGE_PYTHON3_ZLIB for test_uprobes.py. As you noted below, now the kernel provides the headers in a tar file. BCC automatically detect the presence of this file and performs the untarring. Busybox tar was failing to work, hence adding the dependency on proper tar package. No need for xz dependency then or any manual handling to extract the headers. > > > > + help > > + BPF Compiler Collection > > + > > + BCC is a toolkit for creating efficient kernel tracing and > > + manipulation programs, and includes several useful tools and > > + examples. > > + > > + BCC makes BPF programs easier to write, with kernel > > + instrumentation in C (and includes a C wrapper around LLVM), > > + and front-ends in Python and lua.

IMHO the instructions to build the kernel shouldn't be coupled with this package. BCC provides good instructions on how to configure the kernel for BPF support. And it is a fast moving target. There's now CONFIG_DEBUG_INFO_BTF which AFAICT removes the need for the headers. Which config is more suitable should be up to the user to decide. Besides I build the kernel separately, so forcing the dependency is not friendly for this class of users :-) Thanks! -- Qais Yousef

BCC is a toolkit for creating efficient kernel tracing and manipulation programs, and includes several useful tools and examples. Only tested to work on x86_64 and aarch64. I had issues getting i386 and aarch32 to work. More archs support can be added later hopefully after this initial support.
