thermal: intel: powerclamp: Simplify idle_inject_update()

2026-09-04T15:52:46+00:00

Drop the local update variable and call idle_inject_set_duration() directly instead. Also return !should_skip directly. Signed-off-by: Thorsten Blum Link: https://patch.msgid.link/20260828194530.43370-2-blum@kernel.org Signed-off-by: Rafael J. Wysocki

thermal: intel: int340x: Fix temperature selection around 0 C

2026-09-04T15:52:46+00:00

Since commit 7251b9e8a007 ("thermal/intel: Fix intel_tcc_get_temp() to support negative CPU temperature"), intel_tcc_get_temp() can report negative temperatures. proc_thermal_get_zone_temp() still uses *temp as the current maximum and as an implicit "no reading yet" marker. However, this breaks when a CPU reports 0 C, because a subsequent negative reading can overwrite it. Use bool temp_valid to track whether a valid temperature has been read. Initialize *temp with the first valid reading and only update it with warmer readings.

thermal: intel: powerclamp: Drop redundant clamp() in duration_set()

2026-09-04T15:52:46+00:00

duration_set() rejects any new_duration outside the valid range before the assignment, making the clamp() call redundant. Signed-off-by: Thorsten Blum Link: https://patch.msgid.link/20260815095143.3821-2-thorsten.blum@linux.dev Signed-off-by: Rafael J. Wysocki

thermal: intel: powerclamp: Reject invalid window_size values

2026-09-04T15:52:45+00:00

window_size_set() sets ret to -EINVAL if new_window_size is outside the valid range, but then falls through and still updates window_size to the clamped value. Return -EINVAL immediately and do not update window_size. Also drop the now-redundant clamp() call.

thermal: sysfs: switch to use scnprintf() to suppress truncation warning

2026-09-04T13:49:46+00:00

Switch the sysfs code to use scnprintf() to avoid warnings about potential truncation of the names of the sysfs attributes. We can't increase the buffer size because the size is the part of an ABI for some reason. Note, with the current size of buffer the affected attributes have a room for up to 1000 names, which ought to be enough for all cases. There is no functional change, as the same limitation was implied before.
