linux-stable.git/drivers/thermal, branch v5.15 Linux kernel stable tree thermal/drivers/tsens: Fix wrong check for tzd in irq handlers 2021-09-21T13:17:11+00:00 Ansuel Smith ansuelsmth@gmail.com 2021-09-07T21:25:42+00:00 cf96921876dcee4d6ac07b9de470368a075ba9ad Some devices can have some thermal sensors disabled from the factory. The current two irq handler functions check all the sensor by default and the check if the sensor was actually registered is wrong.

thermal/drivers/int340x: Do not set a wrong tcc offset on resume 2021-09-14T17:53:24+00:00 Antoine Tenart atenart@kernel.org 2021-09-09T08:56:12+00:00 8b4bd256674720709a9d858a219fcac6f2f253b5 After upgrading to Linux 5.13.3 I noticed my laptop would shutdown due to overheat (when it should not). It turned out this was due to commit fe6a6de6692e ("thermal/drivers/int340x/processor_thermal: Fix tcc setting"). What happens is this drivers uses a global variable to keep track of the tcc offset (tcc_offset_save) and uses it on resume. The issue is this variable is initialized to 0, but is only set in tcc_offset_degree_celsius_store, i.e. when the tcc offset is explicitly set by userspace. If that does not happen, the resume path will set the offset to 0 (in my case the h/w default being 3, the offset would become too low after a suspend/resume cycle). The issue did not arise before commit fe6a6de6692e, as the function setting the offset would return if the offset was 0. This is no longer the case (rightfully). Fix this by not applying the offset if it wasn't saved before, reverting back to the old logic. A better approach will come later, but this will be easier to apply to stable kernels. The logic to restore the offset after a resume was there long before commit fe6a6de6692e, but as a value of 0 was considered invalid I'm referencing the commit that made the issue possible in the Fixes tag instead.

thermal: intel: Allow processing of HWP interrupt 2021-08-25T18:09:37+00:00 Srinivas Pandruvada srinivas.pandruvada@linux.intel.com 2021-08-20T02:40:05+00:00 950809cd6ca2ff2e2bb9d826c4d9e35d134d7de0 Add a weak function to process HWP (Hardware P-states) notifications and move updating HWP_STATUS MSR to this function.

Add a weak function to process HWP (Hardware P-states) notifications and
move updating HWP_STATUS MSR to this function.

This allows HWP interrupts to be processed by the intel_pstate driver in
HWP mode by overriding the implementation.
