[PATCH v3 0/4] perf: cs-etm: HW_ID improvements

by James Clark

The driver might not always be able to write HW_IDs, but we don't need them for unformatted mode anyway, so fix that in commit ("perf cs-etm: Synthesize missing HW_ID mappings for raw trace"). Include some other minor improvements encountered on the way to appease Sashiko, like properly freeing queues and ("perf: cs-etm: Respect --no-itrace option") makes debugging broken Coresight perf.data files easier.

[PATCH RESEND v13 00/14] fix several inconsistencies with sysfs configuration in etmX

by Yeoreum Yun

The current ETMx configuration via sysfs can lead to the following inconsistencies: - If a configuration is modified via sysfs while a perf session is active, the running configuration may differ between before a sched-out and after a subsequent sched-in. - If a perf session and sysfs session tries to enable concurrently, configuration from configfs could be corrupted (etm4). - There is chance to corrupt drvdata->config if perf session tries to enabled among handling cscfg_csdev_disable_active_config() in etm4_disable_sysfs() (etm4). To resolve these inconsistencies, the configuration should be separated into: - curr_config, which is applied configuration for the current session - config, which stores the settings configured via sysfs. and apply configuration from configfs after taking a mode.

If so, it might be atclk for clocking the module rather than the register interface. Could you confirm this? The replicator is just a middle component on the data path. I read that it shares the same clock with other CoreSight components, so it should still be safe to remove the clock from the replicator node, as other components on the path will ensure that the clock is enabled.

[PATCH v2] coresight: trbe: Hide enable_sink sysfs file

by James Clark

TRBE doesn't support sysfs mode, but the enable_sink file can still be successfully written to enable the device, and only attempting to enable the source would later fail. Avoid misleading users by adding a flag that devices can use to hide either the enable_sink or enable_source files, and set it for TRBE. Don't set it for ETE as it's possible that ETE could appear on the legacy bus and work with sysfs, and writing to enable_source already reports EINVAL if the device doesn't support sysfs mode.

However, I'm afraid the "dbg_trc" and "dbg_apb" clocks are never touched by either the CoreSight driver or the AMBA driver after switching to the dynamic funnel. These clocks should therefore be removed from all CoreSight nodes. Thanks, Leo

[PATCH 0/6] perf: cs-etm: HW_ID improvements

by James Clark

The driver might not always be able to write HW_IDs, but we don't need them for unformatted mode anyway, so fix that in commit ("perf cs-etm: Synthesize missing HW_ID mappings for raw trace"). At the same time, give the driver another chance to send them in commit ("coresight: perf: Retry failed HW_ID writes"). The other commits are semi-related improvements and fixes. ("perf: cs-etm: Respect --no-itrace option") makes debugging broken Coresight perf.data files easier.
