![]() Add a "sinks" directory entry so that users can see all the sinks available in the system in a single place. Individual sink are added as they are registered with the coresight bus. Committer tests: Test built on a ubuntu 18.04 container with a cross build environment to arm64, the new field is there, need to find a machine with this feature to do further testing in the future. root@d15263e5734a:/git/perf# grep CORESIGHT /tmp/build/v5.0-rc2+/.config CONFIG_CORESIGHT=y CONFIG_CORESIGHT_LINKS_AND_SINKS=y CONFIG_CORESIGHT_LINK_AND_SINK_TMC=y CONFIG_CORESIGHT_CATU=y CONFIG_CORESIGHT_SINK_TPIU=y CONFIG_CORESIGHT_SINK_ETBV10=y CONFIG_CORESIGHT_SOURCE_ETM4X=y CONFIG_CORESIGHT_DYNAMIC_REPLICATOR=y CONFIG_CORESIGHT_STM=y CONFIG_CORESIGHT_CPU_DEBUG=m root@d15263e5734a:/git/perf# root@d15263e5734a:/git/perf# file /tmp/build/v5.0-rc2+/drivers/hwtracing/coresight/*.o .../coresight/coresight-catu.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-cpu-debug.mod.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-cpu-debug.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-dynamic-replicator.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-etb10.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-etm-perf.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-etm4x-sysfs.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-etm4x.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-funnel.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-replicator.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-stm.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-tmc-etf.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-tmc-etr.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-tmc.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight-tpiu.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/coresight.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped .../coresight/of_coresight.o: ELF 64-bit MSB relocatable, ARM aarch64, version 1 (SYSV), not stripped root@d15263e5734a:/git/perf# root@d15263e5734a:/git/perf# pahole -C coresight_device /tmp/build/v5.0-rc2+/drivers/hwtracing/coresight/coresight.o struct coresight_device { struct coresight_connection * conns; /* 0 8 */ int nr_inport; /* 8 4 */ int nr_outport; /* 12 4 */ enum coresight_dev_type type; /* 16 4 */ union coresight_dev_subtype subtype; /* 20 8 */ /* XXX 4 bytes hole, try to pack */ const struct coresight_ops * ops; /* 32 8 */ struct device dev; /* 40 1408 */ /* XXX last struct has 7 bytes of padding */ /* --- cacheline 22 boundary (1408 bytes) was 40 bytes ago --- */ atomic_t * refcnt; /* 1448 8 */ bool orphan; /* 1456 1 */ bool enable; /* 1457 1 */ bool activated; /* 1458 1 */ /* XXX 5 bytes hole, try to pack */ struct dev_ext_attribute * ea; /* 1464 8 */ /* size: 1472, cachelines: 23, members: 12 */ /* sum members: 1463, holes: 2, sum holes: 9 */ /* paddings: 1, sum paddings: 7 */ }; root@d15263e5734a:/git/perf# Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> Reviewed-by: Suzuki K Poulose <suzuki.poulose@arm.com> Acked-by: Peter Zijlstra <peterz@infradead.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: H.
