I've edited a couple of changelogs to clarify them a bit and changed the documentation of the new sysfs attributes somewhat, so they don't talk about RAPL directly, because I think that the key point here is that if the power floor is signaled, the configuration of the system needs to be changed in order to reduce power below the current level.
Support power floor notifications for Meteor Lake processors. The first three changes is to prepare for power floor status and others add support for power floor. v2 - Use common define for offset - Fix potential race during clearing of interrupt with workload hint - Address comment for v1 for thermal: int340x: processor_thermal: Support power floor notifications Srinivas Pandruvada (7): thermal: int340x: processor_thermal: Move interrupt status MMIO offset to common header thermal: int340x: processor_thermal: Common function to clear SOC interrupt thermal: int340x: processor_thermal: Set feature mask before proc_thermal_add thermal: int340x: processor_thermal: Support power floor notifications thermal: int340x: processor_thermal: Handle power floor interrupts thermal: int340x: processor_thermal: Enable power floor support selftests/thermel/intel: Add test to read power floor status .../driver-api/thermal/intel_dptf.rst | 8 ++ .../thermal/intel/int340x_thermal/Makefile | 1 + .../processor_thermal_device.c | 68 +++++++++- .../processor_thermal_device.h | 11 ++ .../processor_thermal_device_pci.c | 43 ++++-- .../processor_thermal_power_floor.c | 126 ++++++++++++++++++ .../processor_thermal_wt_hint.c | 3 - tools/testing/selftests/Makefile | 1 + .../thermal/intel/power_floor/Makefile | 12 ++ .../intel/power_floor/power_floor_test.c | 108 +++++++++++++++ 10 files changed, 365 insertions(+), 16 deletions(-) create mode 100644 drivers/thermal/intel/int340x_thermal/processor_thermal_power_floor.c create mode 100644 tools/testing/selftests/thermal/intel/power_floor/Makefile create mode 100644 tools/testing/selftests/thermal/intel/power_floor/power_floor_test.c
