thermal: trip: Use common set of trip type names

2024-06-11T19:04:40Z

Use the same set of trip type names in sysfs and in the thermal debug code output. No intentional functional impact. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

thermal/debugfs: Move some statements from under thermal_dbg->lock

2024-06-11T19:04:34Z

The tz_dbg local variable assignments in thermal_debug_tz_trip_up(), thermal_debug_tz_trip_down(), and thermal_debug_update_trip_stats() need not be carried out under thermal_dbg->lock, so move them from under that lock (to avoid possible future confusion). While at it, reorder local variable definitions in thermal_debug_tz_trip_up() for more clarity. No functional impact. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

thermal/debugfs: Compute maximum temperature for mitigation episode as a whole

2024-06-11T19:04:28Z

Notice that the maximum temperature above the trip point must be the same for all of the trip points involved in a given mitigation episode, so it need not be computerd for each of them separately. It is sufficient to compute the maximum temperature for the mitigation episode as a whole and print it accordingly, so do that. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

thermal/debugfs: Adjust check for trips without statistics in tze_seq_show()

2024-06-11T19:04:21Z

Initialize the trip_temp field in struct trip_stats to THERMAL_TEMP_INVALID and adjust the check for trips without statistics in tze_seq_show() to look at that field instead of comparing min and max. This will mostly be useful to simplify subsequent changes. No intentional functional impact. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

thermal/debugfs: Fix up units in "mitigations" files

2024-06-11T19:04:13Z

Print temperature units as m°C rather than °mC (the meaning of which is unclear) and add time unit to the duration column. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

thermal/debugfs: Print mitigation timestamp value in milliseconds

2024-06-11T19:04:06Z

Because mitigation episode duration is printed in milliseconds, there is no reason to print timestamp information for mitigation episodes in smaller units which also makes it somewhat harder to interpret the numbers. Print it in milliseconds for consistency. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

thermal/debugfs: Do not extend mitigation episodes beyond system resume

2024-06-11T19:04:00Z

Because thermal zone handling by the thermal core is started from scratch during resume from system-wide suspend, prevent the debug code from extending mitigation episodes beyond that point by ending the mitigation episode currently in progress, if any, for each thermal zone.

thermal/debugfs: Use helper to update trip point overstepping duration

2024-06-11T19:01:21Z

Add a helper for updating trip point overstepping duration to be called from thermal_debug_tz_trip_down(). Subsequently, it will also be used during resume from system-wide suspend. No intentional functional impact. Signed-off-by: Rafael J. Wysocki Acked-by: Daniel Lezcano

thermal/debugfs: Allow tze_seq_show() to print statistics for invalid trips

2024-05-27T11:00:00Z

Commit a6258fde8de3 ("thermal/debugfs: Make tze_seq_show() skip invalid trips and trips with no stats") modified tze_seq_show() to skip invalid trips, but it overlooked the fact that a trip may become invalid during a mitigation eposide involving it, in which case its statistics should still be reported. For this reason, remove the invalid trip temperature check from the main loop in tze_seq_show(). The trips that have never been valid will still be skipped after this change because there are no statistics to report for them.

thermal/debugfs: Print initial trip temperature and hysteresis in tze_seq_show()

2024-05-27T11:00:00Z

The temperature and hysteresis of a trip point may change during a mitigation episode it is involved in (it may even become invalid altogether), so in order to avoid possible confusion related to that, store the temperature and hysteresis of trip points at the time they are crossed on the way up and print those values instead of their current temperature and hysteresis.
