Well, only one of the patches, not strictly related to eBPF gave me some work: commit 266fa2b22294909ddf6e7d2f8acfe07adf9fd978 Author: Arnaldo Carvalho de Melo <acme@redhat.com> Date: Thu Sep 24 11:24:18 2015 -0300 perf probe: Use existing routine to look for a kernel module by dso->short_name And some patches came from Masami that I think were somehow related to things you reported, had to review/test/apply/push those as well. - Arnaldo > I have finished my vacation.

Hi Arnaldo, Have we made any progress on this patch set? I have finished my vacation. In this new pull request, I rebase BPF patches onto the newest perf/core, and fix a document problem in Makefile.perf. The following changes since commit ae938802443732e77d01f8d5b52b900b9327ff30: perf python: Support the PERF_RECORD_SWITCH event (2015-10-07 19:41:50 -0300) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/pi3orama/linux tags/perf-ebpf-for-acme-20151008 for you to fetch changes up to 60d6b3bceb3d87497c542dec61e4a968d9e2b488: perf test: Test BPF prologue (2015-10-08 07:23:33 +0000) ---------------------------------------------------------------- EBPF support for perf - Rebase to newest perf/core - Fix a document problem in Makefile.perf: NO_BPF -> NO_LIBBPF Signed-off-by: Wang Nan <wangnan0@huawei.com> ---------------------------------------------------------------- He Kuang (2): perf tools: Add prologue for BPF programs for fetching arguments perf record: Support custom vmlinux path Wang Nan (20): perf tools: Make perf depend on libbpf perf ebpf: Add the libbpf glue perf tools: Enable passing bpf object file to --event perf record, bpf: Create probe points for BPF programs perf record: Load eBPF object into kernel perf tools: Collect perf_evsel in BPF object files perf tools: Attach eBPF program to perf event perf record: Add clang options for compiling BPF scripts perf tools: Compile scriptlets to BPF objects when passing '.c' to --event perf test: Enforce LLVM test for BPF test perf test: Add 'perf test BPF' perf probe: Reset args and nargs for probe_trace_event when failure bpf tools: Load a program with different instances using preprocessor perf tools: Add BPF_PROLOGUE config options for further patches perf tools: Compile dwarf-regs.c if CONFIG_BPF_PROLOGUE is on perf tools: Generate prologue for BPF programs perf tools: Use same BPF program if arguments are identical perf tools: Allow BPF program attach to uprobe events perf test: Enforce LLVM test, add kbuild test perf test: Test BPF prologue tools/build/Makefile.feature | 6 +- tools/lib/bpf/libbpf.c | 143 +++++- tools/lib/bpf/libbpf.h | 22 + tools/perf/MANIFEST | 3 + tools/perf/Makefile.perf | 21 +- tools/perf/arch/x86/util/Build | 1 + tools/perf/builtin-record.c | 11 + tools/perf/config/Makefile | 31 +- tools/perf/perf.c | 2 + tools/perf/tests/Build | 24 +- tools/perf/tests/bpf-script-example.c | 48 ++ tools/perf/tests/bpf-script-test-kbuild.c | 21 + tools/perf/tests/bpf-script-test-prologue.c | 35 ++ tools/perf/tests/bpf.c | 227 ++++++++++ tools/perf/tests/builtin-test.c | 10 + tools/perf/tests/llvm.c | 210 ++++++++- tools/perf/tests/llvm.h | 29 ++ tools/perf/tests/make | 4 +- tools/perf/tests/tests.h | 5 + tools/perf/util/Build | 2 + tools/perf/util/bpf-loader.c | 677 ++++++++++++++++++++++++++++ tools/perf/util/bpf-loader.h | 94 ++++ tools/perf/util/bpf-prologue.c | 443 ++++++++++++++++++ tools/perf/util/bpf-prologue.h | 34 ++ tools/perf/util/evsel.c | 17 + tools/perf/util/evsel.h | 1 + tools/perf/util/parse-events.c | 115 +++++ tools/perf/util/parse-events.h | 9 + tools/perf/util/parse-events.l | 6 + tools/perf/util/parse-events.y | 29 +- tools/perf/util/probe-finder.c | 4 + 31 files changed, 2248 insertions(+), 36 deletions(-) create mode 100644 tools/perf/tests/bpf-script-example.c create mode 100644 tools/perf/tests/bpf-script-test-kbuild.c create mode 100644 tools/perf/tests/bpf-script-test-prologue.c create mode 100644 tools/perf/tests/bpf.c create mode 100644 tools/perf/tests/llvm.h create mode 100644 tools/perf/util/bpf-loader.c create mode 100644 tools/perf/util/bpf-loader.h create mode 100644 tools/perf/util/bpf-prologue.c create mode 100644 tools/perf/util/bpf-prologue.h
