perf auxtrace: Make auxtrace_queues__add_buffer() do CPU filtering

2018-04-06T12:40:41Z

In preparation for supporting AUX area sampling buffers, auxtrace_queues__add_buffer() needs to be more generic. To that end, move CPU filtering into it.

perf tools: Add ARM Statistical Profiling Extensions (SPE) support

2018-01-17T13:23:31Z

'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. Output will contain raw SPE data and its textual representation, such as: 0x5c8 [0x30]: PERF_RECORD_AUXTRACE size: 0x200000 offset: 0 ref: 0x1891ad0e idx: 1 tid: 2227 cpu: 1 . . ...

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 Reviewed-by: Dongjiu Geng Acked-by: Adrian Hunter Cc: Alexander Shishkin Cc: Andi Kleen Cc: Jiri Olsa Cc: linux-arm-kernel@lists.infradead.org Cc: Marc Zyngier Cc: Mark Rutland Cc: Mathieu Poirier Cc: Pawel Moll Cc: Peter Zijlstra Cc: Rob Herring Cc: Suzuki Poulouse Cc: Thomas Gleixner Cc: Wang Nan Cc: Will Deacon Link: http://lkml.kernel.org/r/20180114132850.0b127434b704a26bad13268f@arm.com Signed-off-by: Arnaldo Carvalho de Melo
