[PATCH] coresight: etm4x: Fix use-after-free of per-cpu etm drvdata

by Suzuki K Poulose

etm probe could be deferred due to the dependency in the trace path chain and may be retried. We need to clear the per-cpu etmdrvdata entry for the etm in case of a failure to avoid use-after-free cases as reported below: KASAN use-after-free bug in etm4_cpu_pm_notify(): [ 8.574566] coresight

[RFC PATCH v2 0/5] Allow CoreSight to specify and select default sink

by Mike Leach

This patchset provides a proposed infrastructure to allow for the automatic selection of a sink during CoreSight tracing operations. Currently starting tracing using perf requires a sink selection on the command line:- sudo ./perf record -e cs_etm/@tmc_etr0/ --per-thread uname -a After this set the infrastructure will be able to select a default sink:- sudo ./perf record -e cs_etm// --per-thread uname -a This matches with the default operation provided with perf and intelpt. The CoreSight infrastructure is updated with the concept of a sink_select_priority value used when sinks are registered with the system. Where no sink is specified at the start of a trace session, the CoreSight system will walk the connection graph from the source ETM, to find a suitable sink using the first encountered highest priority device. Sinks set a value during component registration, ETR the highest priority, ETB and ETF a lower priority. Thus the first ETR if present will be used, otherwise fallback to the first encountered ETF/ETB. The automatic sink selection will also operate if an ETM is enabled using sysfs commands, and no sink is currently enabled. Applied to Linux 5.7-rc3. Changes since v1: 1) Dropped the device-tree attribute labelling of sinks for selection and implemented the priority schema preferring first encountered ETR, after mailing list discussions. 2) Added in sysfs support for auto sink selection. Mike Leach (5): coresight: Add default sink selection to CoreSight base coresight: tmc: Add default sink selection priorities. coresight: etm: perf: Add default sink selection to etm perf coresight: sysfs: Allow select default sink on source enable. perf: cs-etm: Allow no CoreSight sink to be specified on command line .../hwtracing/coresight/coresight-etm-perf.c | 20 ++++- drivers/hwtracing/coresight/coresight-priv.h | 2 + drivers/hwtracing/coresight/coresight-tmc.c | 5 ++ drivers/hwtracing/coresight/coresight.c | 87 ++++++++++++++++++- include/linux/coresight.h | 10 ++- tools/perf/arch/arm/util/cs-etm.c | 6 +- 6 files changed, 121 insertions(+), 9 deletions(-) -- 2.17.1

[PATCH v2] perf: cs-etm: Update to build with latest opencsd version.

by Mike Leach

OpenCSD version v0.14.0 adds in a new output element. This is represented by a new value in the generic element type enum, which must be added to the handling code in perf cs-etm-decoder to prevent build errors due to build options on the perf project. This element is not currently used by the perf decoder. Perf build feature test updated to require a minimum of 0.14.0 Tested on Linux 5.7-rc3.

[PATCH v2 0/2] Add CPU power management for CPU bound CTI devices.

by Mike Leach

Adds in power management for CPU bound CTI devices: i) CPU Hotplug - registers a new notifier for CPU start and stop events. ii) CPU idle PM event notifier to handle PM_ENTER, PM_ENTER_FAILED and PM_EXIT events. Tested with DB410c on Linux 5.7-rc3. Rebased onto coresight/next Changes since V1: (requested by Mathieu). 1) Split into separate patches for CPU pm and CPU hotplug handling. 2) Enable on hotplug has a specific function to enable the hardware, while leaving the enable reference counts unchanged.
