I hope it work. The following changes since commit acc60583a43fe93ff42d707a39d478c7dbe24028: perf tools: Fix Intel PT timestamp handling (2015-08-20 16:45:01 -0300) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/pi3orama/linux tags/perf-ebpf-for-acme-20150821 for you to fetch changes up to 15756861299809103c00d9342352eb22bb84f20f: perf tools: Support attach BPF program on uprobe events (2015-08-21 03:57:12 +0000) ---------------------------------------------------------------- perf bpf improvements: - Improve 'perf test BPF' Don't use the hacking way in previous series that make perf act test target and run 'perf record' using system(). In this series, perf test BPF open the evlist and evsel, attach then record, analysis result in its own context. - Improve error reporting Use strerror style error reporting. Only output debug information in bpf-loader.c. Signed-off-by: Wang Nan ---------------------------------------------------------------- He Kuang (3): perf tools: Move linux/filter.h to tools/include perf tools: Introduce arch_get_reg_info() for x86 perf record: Support custom vmlinux path Wang Nan (24): perf probe: Try to use symbol table if searching debug info failed perf tools: Make perf depend on libbpf perf ebpf: Add the libbpf glue perf tools: Enable passing bpf object file to --event perf probe: Attach trace_probe_event with perf_probe_event perf record, bpf: Parse and probe eBPF programs probe points perf bpf: Collect 'struct perf_probe_event' for bpf_program perf record: Load all eBPF object into kernel perf tools: Add bpf_fd field to evsel and config it perf tools: Attach eBPF program to perf event perf tools: Suppress probing messages when probing by BPF loading perf record: Add clang options for compiling BPF scripts perf tools: Infrastructure for compiling scriptlets when passing '.c' to --event perf tests: Enforce LLVM test for BPF test perf test: Add 'perf test BPF' bpf tools: Load a program with different instances using preprocessor perf tools: Fix probe-event.h include perf probe: Reset args and nargs for probe_trace_event when failure perf tools: Add BPF_PROLOGUE config options for further patches perf tools: Add prologue for BPF programs for fetching arguments perf tools: Generate prologue for BPF programs perf tools: Use same BPF program if arguments are identical perf probe: Init symbol as kprobe perf tools: Support attach BPF program on uprobe events tools/build/Makefile.feature | 6 +- tools/include/linux/filter.h | 237 +++++++++++ tools/lib/bpf/libbpf.c | 143 ++++++- tools/lib/bpf/libbpf.h | 22 ++ tools/perf/MANIFEST | 4 + tools/perf/Makefile.perf | 19 +- tools/perf/arch/x86/Makefile | 1 + tools/perf/arch/x86/util/Build | 2 + tools/perf/arch/x86/util/dwarf-regs.c | 104 +++-- tools/perf/builtin-probe.c | 4 +- tools/perf/builtin-record.c | 52 ++- tools/perf/config/Makefile | 31 +- tools/perf/tests/Build | 10 +- tools/perf/tests/bpf-script-example.c | 44 +++ tools/perf/tests/bpf.c | 170 ++++++++ tools/perf/tests/builtin-test.c | 12 + tools/perf/tests/llvm.c | 123 +++++- tools/perf/tests/llvm.h | 15 + tools/perf/tests/make | 4 +- tools/perf/tests/tests.h | 3 + tools/perf/util/Build | 2 + tools/perf/util/bpf-loader.c | 723 ++++++++++++++++++++++++++++++++++ tools/perf/util/bpf-loader.h | 92 +++++ tools/perf/util/bpf-prologue.c | 442 +++++++++++++++++++++ tools/perf/util/bpf-prologue.h | 34 ++ tools/perf/util/evlist.c | 41 ++ tools/perf/util/evlist.h | 1 + tools/perf/util/evsel.c | 17 + tools/perf/util/evsel.h | 1 + tools/perf/util/include/dwarf-regs.h | 7 + tools/perf/util/parse-events.c | 26 ++ tools/perf/util/parse-events.h | 4 + tools/perf/util/parse-events.l | 6 + tools/perf/util/parse-events.y | 29 +- tools/perf/util/probe-event.c | 86 ++-- tools/perf/util/probe-event.h | 8 +- tools/perf/util/probe-file.c | 5 +- tools/perf/util/probe-finder.c | 4 + 38 files changed, 2432 insertions(+), 102 deletions(-) create mode 100644 tools/include/linux/filter.h create mode 100644 tools/perf/tests/bpf-script-example.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 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
