Re: [RFC PATCH v3 1/1] perf cs-etm: Set time value for samples

by James Clark

Hi Wojciech, Are you still working on this patchset here? https://lists.linaro.org/pipermail/coresight/2019-June/002871.html I'm asking because I was also looking to make a change related to timestamps, and I see there has been quite a bit of discussion on your one over the revisions. My change would be something like I've pasted below. This was suggested by Al Grant so that the synthesized samples have kernel timestamps that can be correlated (at least roughly) with MMAP and COMM records. The issue is that in your patchset, you are also setting the sample.time field, but with the decoded timestamp rather than the kernel one. I suppose this email is to re-start the discussion with the whole mailing list about what should be in that field.

[PATCH v4 00/10] CoreSight configuration management; ETM strobing

by Mike Leach

This patchset introduces initial concepts in CoreSight system configuration management support. to allow more detailed and complex programming to be applied to CoreSight systems during trace capture. Configurations consist of 2 elements:- 1) Features - programming combinations for devices, applied to a class of device on the system (all ETMv4), or individual devices. 2) Configurations - a set of programmed features used when the named configuration is selected. Features and configurations are declared as a data table, a set of register, resource and parameter requirements. Features and configurations are loaded into the system by the virtual cs_syscfg device. This then matches features to any registered devices and loads the feature into them. Individual device classes that support feature and configuration register with cs_syscfg. Once loaded a configuration can be enabled for a specific trace run. Configurations are registered with the perf cs_etm event as entries in cs_etm/cs_config. These can be selected on the perf command line as follows:- perf record -e cs_etm/<config_name>/ ... This patch set has one pre-loaded configuration and feature. A named "strobing" feature is provided for ETMv4. A named "autofdo" configuration is provided. This configuration enables strobing on any ETM in used. Thus the command: perf record -e cs_etm/autofdo/ ... will trace the supplied application while enabling the "autofdo" configuation on each ETM as it is enabled by perf. This in turn will enable strobing for the ETM - with default parameters. Parameters can be adjusted using configfs. The sink used in the trace run will be automatically selected. A configuation can supply up to 15 of preset parameter values, which will subsitute in parameter values for any feature used in the configuration. Selection of preset values as follows perf record -e cs_etm/autofdo,preset=1/ ... (valid presets 1-N, where N is the number supplied in the configuration, not exceeding 15. preset=0 is the same as not selecting a preset.) Applies to coresight/next (5.11-rc2 base) Changes since v3: (Primarily based on comments from Matthieu) 1) Locking mechanisms simplified. 2) Removed the possibility to enable features independently from configurations.Only configurations can be enabled now. Simplifies programming logic. 3) Configuration now uses an activate->enable mechanism. This means that perf will activate a selected configuration at the start of a session (during setup_aux), and disable at the end of a session (around free_aux) The active configuration and associated features will be programmed into the CoreSight device instances when they are enabled. This locks the configuration into the system while in use. Parameters cannot be altered while this is in place. This mechanism will be extended in future for dynamic load / unload of configurations to prevent removal while in use. 4) Removed the custom bus / driver as un-necessary. A single device is registered to own perf fs elements and configfs. 5) Various other minor issues addressed. Changes since v2: 1) Added documentation file. 2) Altered cs_syscfg driver to no longer be coresight_device based, and moved to its own custom bus to remove it from the main coresight bus. (Mathieu) 3) Added configfs support to inspect and control loaded configurations and features. Allows listing of preset values (Yabin Cui) 4) Dropped sysfs support for adjusting feature parameters on the per device basis, in favour of a single point adjustment in configfs that is pushed to all device instances. 5) Altered how the config and preset command line options are handled in perf and the drivers. (Mathieu and Suzuki). 6) Fixes for various issues and technical points (Mathieu, Yabin) Changes since v1: 1) Moved preloaded configurations and features out of individual drivers. 2) Added cs_syscfg driver to manage configurations and features. Individual drivers register with cs_syscfg indicating support for config, and provide matching information that the system uses to load features into the drivers. This allows individual drivers to be updated on an as needed basis - and removes the need to consider devices that cannot benefit from configuration - static replicators, funnels, tpiu. 3) Added perf selection of configuarations. 4) Rebased onto the coresight module loading set. To follow in future revisions / sets:- a) load of additional config and features by loadable module. b) load of additional config and features by configfs c) enhanced resource management for ETMv4 and checking features have sufficient resources to be enabled. d) ECT and CTI support for configuration and features.

In the kernel tree - Documentation/trace/coresight/coresight-etm4x-reference.rst - has lots of information on programming these sysfs files.

You will need to capture trace, decode then run an analysis on that decode to determine what branches have been taken. ETMv4 is program flow trace - so all branches are marked as taken or not taken.
