Subject: [PATCH v2 00/17] perf tools: Coresight: Add CPU-wide trace support
Date: Fri, 24 May 2019 11:34:51 -0600 [thread overview]
Message-ID: <20190524173508.29044-1-mathieu.poirier@linaro.org> (raw)
This patchset adds support for CoreSight CPU-wide trace scenarios. More
specifically it extends the work that was done for per thread scenarios to
handle more than a single trace ID. It also temporally correlate traces
based on timestamp generated by the tracers so that rendering by the perf
mechanic is ordered.
Everything is based on Arnaldo's perf/core branch (46d4c9a05285). I will
send another revision when it is rebased to a 5.2 rc candidate.
Before this set:
# root@juno:/home/linaro# perf record -e cs_etm/@20070000.etr/ -C 2,3 sleep 1
failed to mmap with 12 (Cannot allocate memory)
After this set:
# root@juno:/home/linaro# perf record -e cs_etm/@20070000.etr/ -C 2,3 sleep 1
[ perf record: Captured and wrote 1.352 MB perf.data ]
Regards,
Mathieu
Changes for V2:
* Fixed error condition in function cs_etm_set_option() (Leo)
* Fixed changelog spelling error (Leo).
* Moved from calloc() to malloc() in cs_etm__etmq_get_traceid_queue()
* Got rid of CS_ETM_PACKET_QUEUE_NR macro
* Fixed indentation problem in function cs_etm__process_traceid_queue() (Leo).
