[RESEND PATCH V4 09/26] coresight: add API to get sink from path

Add an API allowing external code to quickly get a handle on the sink within a path. The sink is always last, but adding an API allows to keep the path's node structure private and remove redundant checks. Signed-off-by: Mathieu Poirier ---

[RESEND PATCH V4 03/26] coresight: etm3x: unlocking tracers in default arch init

Calling function 'smp_call_function_single()' to unlock a tracer and calling it again right after to perform the default initialisation doesn't make sense. Moving 'etm_os_unlock()' just before making the default initialisation results in the same outcome while saving one call to

[RESEND PATCH V4 05/26] coresight: etm3x: implementing 'cpu_id()' API

Other than plainly parsing the device tree there is no way to know which CPU a tracer is affined to. As such adding an interface to lookup the CPU field enclosed in the etm_drvdata structure that was initialised at boot time. Signed-off-by: Mathieu Poirier ---

[RESEND PATCH V4 02/26] coresight: etm3x: moving sysFS entries to dedicated file

SysFS entries are big enough to justify their own file. As such moving all sysFS related declarations to a dedicated location. Signed-off-by: Mathieu Poirier --- drivers/hwtracing/coresight/Makefile |3 +- drivers/hwtracing/coresight/coresight-etm.h

[RESEND PATCH V4 04/26] coresight: etm3x: splitting struct etm_drvdata

Structure "etm_drvdata" carries the tracer's static configuration (as laid out in hardware) and the session specific configuration determined by users. This doesn't work when tracers are to support multiple, simultaneous, tracing session. As such splitting "etm_drvdata" in two sections, one for

[RESEND PATCH V4 01/26] coresight: etm3x: moving etm_readl/writel to header file

Moving functions etm_readl/writel to file "coresight-etm.h" so that the main ETM3x driver can be split in more than one file. Signed-off-by: Mathieu Poirier --- drivers/hwtracing/coresight/coresight-etm.h | 29 +++

[PATCH v12 27/30] tracing: Add support for named hist triggers

Allow users to define 'named' hist triggers. All triggers created with the same 'name=xxx' option will update the same shared histogram data. This expands the hist trigger syntax from this: # echo hist:keys=xxx ... [ if filter] > event/trigger to this: # echo hist:name=xxx:keys=xxx

[PATCH v12 16/30] tracing: Add hist trigger 'hex' modifier for displaying numeric fields

Allow users to have numeric fields displayed as hex values in the output by appending '.hex' to field names: # echo hist:keys=aaa,bbb.hex:vals=ccc.hex ... \ [ if filter] > event/trigger Signed-off-by: Tom Zanussi Tested-by: Masami Hiramatsu

[PATCH v12 20/30] tracing: Add hist trigger support for stacktraces as keys

It's often useful to be able to use a stacktrace as a hash key, for keeping a count of the number of times a particular call path resulted in a trace event, for instance. Add a special key named 'stacktrace' which can be used as key in a 'keys=' param for this purpose: # echo

[PATCH cgroup/for-4.4-fixes] cgroup: make css_set pin its css's to avoid use-afer-free

A css_set represents the relationship between a set of tasks and css's. css_set never pinned the associated css's. This was okay because tasks used to always disassociate immediately (in RCU sense) - either a task is moved to a different css_set or exits and never accesses css_set again.

[PATCH v12 29/30] kselftests/ftrace: Add hist trigger testcases

From: Masami Hiramatsu Add the hist trigger testcases for ftracetest. This checks the basic histogram trigger behaviors like as; - Histogram trigger itself - Histogram with string key - Histogram with compound keys - Histogram with sort key - Histogram

[PATCH v12 13/30] tracing: Add hist trigger support for user-defined sorting ('sort=' param)

Allow users to specify keys and/or values to sort on. With this addition, keys and values specified using the 'keys=' and 'vals=' keywords can be used to sort the hist trigger output via a new 'sort=' keyword. If multiple sort keys are specified, the output will be sorted using the second key as

[PATCH v12 28/30] kselftests/ftrace : Add event trigger testcases

From: Masami Hiramatsu This adds simple event trigger testcases for ftracetest, which covers following triggers. - traceon-traceoff trigger - enable/disable_event trigger - snapshot trigger - stacktrace trigger - trigger filters Here is the test result.

[PATCH v12 12/30] tracing: Add hist trigger support for compound keys

Allow users to specify multiple trace event fields to use in keys by allowing multiple fields in the 'keys=' keyword. With this addition, any unique combination of any of the fields named in the 'keys' keyword will result in a new entry being added to the hash table. Signed-off-by: Tom Zanussi

[PATCH v12 18/30] tracing: Add hist trigger 'execname' modifier

[PATCH v12 15/30] tracing: Add hist trigger support for clearing a trace

Allow users to append 'clear' to an existing trigger in order to have the hash table cleared. This expands the hist trigger syntax from this: # echo hist:keys=xxx:vals=yyy:sort=zzz.descending:pause/cont \ [ if filter] >> event/trigger to this: # echo

[PATCH v12 07/30] tracing: Add needs_rec flag to event triggers

Add a new needs_rec flag for triggers that require unconditional access to trace records in order to function. Normally a trigger requires access to the contents of a trace record only if it has a filter associated with it (since filters need the contents of a record in order to make a filtering

[PATCH v12 11/30] tracing: Add hist trigger support for multiple values ('vals=' param)

Allow users to specify trace event fields to use in aggregated sums via a new 'vals=' keyword. Before this addition, the only aggregated sum supported was the implied value 'hitcount'. With this addition, 'hitcount' is also supported as an explicit value field, as is any numeric trace event

[PATCH v2, resend 3/6] kernel/cpu.c: export __cpu_*_mask

Exporting the cpumasks __cpu_possible_mask and friends will allow us to remove the extra indirection through the cpu_*_mask variables. It will also allow the set_cpu_* functions to become static inlines, which will give a .text reduction. Acked-by: Rusty Russell

[PATCH v12 10/30] tracing: Add 'hist' event trigger command

'hist' triggers allow users to continually aggregate trace events, which can then be viewed afterwards by simply reading a 'hist' file containing the aggregation in a human-readable format. The basic idea is very simple and boils down to a mechanism whereby trace events, rather than being
