91193b27 - drivers/hwtracing/stm: Remove "select SRCU"

Wed, 23 Nov 2022 01:22:10 +0000

drivers/hwtracing/stm: Remove "select SRCU"Now that the SRCU Kconfig option is unconditionally selected, there isno longer any point in selecting it. Therefore, remove the "select SRCU"Kconfig statements.Signed-off-by: Paul E.

d69d5e83 - stm class: Add MIPI SyS-T protocol support

Fri, 05 Oct 2018 12:42:58 +0000

stm class: Add MIPI SyS-T protocol supportThis adds support for MIPI SyS-T protocol as specified in an openstandard [1]. In addition to marking message boundaries, it alsosupports tagging messages with the source UUID, to provide betterdistinction between trace sources, including payload length andtimestamp in the message's metadata.This driver adds attributes to STP policy nodes to control/configurethese metadata features.[1] https://www.mipi.org/specifications/sys-tSigned-off-by: Alexander Shishkin Tested-by: Mathieu Poirier Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/hwtracing/stm/Kconfig

stm class: Factor out default framing protocolThe STP framing pattern that the stm class implicitly applies to thedata payload is, in fact, a protocol.

Mon, 21 Nov 2016 07:57:19 +0000

stm class: ftrace: Add ftrace-export-over-stm driverThis patch adds a driver that models itself as an stm_source calledstm_ftrace. Once the stm device and stm_ftrace have been linked viasysfs, the driver registers itself as a trace_export and everythingpassed to the interface from Ftrace subsystem will end up in the STMtrace engine.Link: http://lkml.kernel.org/r/1479715043-6534-3-git-send-email-zhang.chunyan@linaro.orgSigned-off-by: Chunyan Zhang Acked-by: Alexander Shishkin Signed-off-by: Steven Rostedt List of files: /linux-6.15/drivers/hwtracing/stm/Kconfig

stm class: Add heartbeat stm source deviceHeartbeat stm source may have multiple instances (for connecting todifferent stm devices). Each instance will send a periodic test messageover its stm device when it is linked.

7bd1d409 - stm class: Introduce an abstraction for System Trace Module devices

Tue, 22 Sep 2015 12:47:10 +0000

stm class: Introduce an abstraction for System Trace Module devicesA System Trace Module (STM) is a device exporting data in System TraceProtocol (STP) format as defined by MIPI STP standards. Examples of suchdevices are Intel(R) Trace Hub and Coresight STM.This abstraction provides a unified interface for software trace sourcesto send their data over an STM device to a debug host. In order to dothat, such a trace source needs to be assigned a pair of master/channelidentifiers that all the data from this source will be tagged with. TheSTP decoder on the debug host side will use these master/channel tags todistinguish different trace streams from one another inside one STPstream.This abstraction provides a configfs-based policy management mechanismfor dynamic allocation of these master/channel pairs based on tracesource-supplied string identifier. It has the flexibility of beingdefined at runtime and at the same time (provided that the policydefinition is aligned with the decoding end) consistency.For userspace trace sources, this abstraction provides write()-based andmmap()-based (if the underlying stm device allows this) output mechanism.For kernel-side trace sources, we provide "stm_source" device class thatcan be connected to an stm device at run time.Cc: linux-api@vger.kernel.orgReviewed-by: Mathieu Poirier Signed-off-by: Alexander Shishkin Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/hwtracing/stm/Kconfig
