perf util: Make util its own library Make the util directory into its own library. This is done to avoid compiling code twice, once for the perf tool and once for the perf python module. For convenience: arch/common.c scripts/perl/Perf-Trace-Util/Context.c scripts/python/Perf-Trace-Util/Context.c are made part of this library.

perf tools: Add ARM Statistical Profiling Extensions (SPE) support 'perf record' and 'perf report --dump-raw-trace' supported in this release. Example usage: # perf record -e arm_spe/ts_enable=1,pa_enable=1/ dd if=/dev/zero of=/dev/null count=10000 # perf report --dump-raw-trace Note that the perf.data file is portable, so the report can be run on another architecture host if necessary.

Other release notes: - applies to acme's perf/{core,urgent} branches, likely elsewhere - Report is self-contained within the tool. Record requires enabling the kernel SPE driver by setting CONFIG_ARM_SPE_PMU. - The intel-bts implementation was used as a starting point; its min/default/max buffer sizes and power of 2 pages granularity need to be revisited for ARM SPE - Recording across multiple SPE clusters/domains not supported - Snapshot support (record -S), and conversion to native perf events (e.g., via 'perf inject --itrace'), are also not supported - Technically both cs-etm and spe can be used simultaneously, however disabled for simplicity in this release Signed-off-by: Kim Phillips <kim.phillips@arm.com> Reviewed-by: Dongjiu Geng <gengdongjiu@huawei.com> Acked-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: linux-arm-kernel@lists.infradead.org Cc: Marc Zyngier <marc.zyngier@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Mathieu Poirier <mathieu.poirier@linaro.org> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Rob Herring <robh@kernel.org> Cc: Suzuki Poulouse <suzuki.poulose@arm.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Wang Nan <wangnan0@huawei.com> Cc: Will Deacon <will.deacon@arm.com> Link: http://lkml.kernel.org/r/20180114132850.0b127434b704a26bad13268f@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf auxtrace arm64: Add support for HiSilicon PCIe Tune and Trace device driver HiSilicon PCIe tune and trace device (PTT) could dynamically tune the PCIe link's events, and trace the TLP headers). This patch add support for PTT device in perf tool, so users could use 'perf record' to get TLP headers trace data.
