Please see below. Since patch order is changed (original 20/32 and 32/32 are dropped), I decide to send all of them again. Sorry for the noisy. In addition: I collect a cross-compiling fix I posted yesterday into this cset (the last one). The following changes since commit 2c07144dfce366e21465cc7b0ada9f0b6dc7b7ed: perf evlist: Add backpointer for perf_env to evlist (2015-08-28 14:54:14 -0300) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/pi3orama/linux tags/perf-ebpf-for-acme-20150829 for you to fetch changes up to d4a337392b3724899a084170d9ea36a8e2392097: tools lib traceevent: Support function __get_dynamic_array_len (2015-08-29 02:57:40 +0000) ---------------------------------------------------------------- perf BPF related improvements and bugfix: - Rebase to Arnaldo's newest perf/core. - Fix a missing include in builtin-trace.c. - Drop patch 'perf tools: Fix probe-event.h include' since the problem has been fixed by commit 5a023b57. - Fix a cross compiling error (introduced by inter pt). - Drop patch 'bpf: Introduce function for outputing data to perf event' because we want to do better. Signed-off-by: Wang Nan ---------------------------------------------------------------- He Kuang (4): perf tools: Move linux/filter.h to tools/include perf tools: Introduce arch_get_reg_info() for x86 perf record: Support custom vmlinux path tools lib traceevent: Support function __get_dynamic_array_len Wang Nan (27): bpf tools: New API to get name from a BPF object perf tools: Don't set cmdline_group_boundary if no evsel is collected perf tools: Introduce dummy evsel 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: Allow filter option to be applied to bof object 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 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 perf tools: Fix cross compiling error tools/build/Makefile.feature | 6 +- tools/include/linux/filter.h | 237 +++++++ tools/lib/bpf/libbpf.c | 168 ++++- tools/lib/bpf/libbpf.h | 26 +- tools/lib/traceevent/event-parse.c | 56 +- tools/lib/traceevent/event-parse.h | 1 + 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 | 64 +- tools/perf/builtin-stat.c | 9 +- tools/perf/builtin-top.c | 11 +- tools/perf/builtin-trace.c | 7 +- 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 | 125 +++- tools/perf/tests/llvm.h | 15 + tools/perf/tests/make | 4 +- tools/perf/tests/tests.h | 3 + tools/perf/util/Build | 4 +- tools/perf/util/bpf-loader.c | 730 +++++++++++++++++++++ tools/perf/util/bpf-loader.h | 95 +++ tools/perf/util/bpf-prologue.c | 442 +++++++++++++ tools/perf/util/bpf-prologue.h | 34 + tools/perf/util/evlist.c | 107 +++ tools/perf/util/evlist.h | 2 + tools/perf/util/evsel.c | 49 ++ tools/perf/util/evsel.h | 7 + tools/perf/util/include/dwarf-regs.h | 7 + tools/perf/util/parse-events.c | 73 ++- 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 | 79 ++- tools/perf/util/probe-event.h | 7 +- tools/perf/util/probe-file.c | 5 +- tools/perf/util/probe-finder.c | 4 + .../perf/util/scripting-engines/trace-event-perl.c | 1 + .../util/scripting-engines/trace-event-python.c | 1 + 45 files changed, 2698 insertions(+), 121 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 -- 2.1.0 -- 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/
