Subject: [PATCH v2 0/3] drivers: thermal/hwmon: intel: Use model-specific bitmasks for temperature registers
Date: Thu, 25 Apr 2024 10:13:08 -0700 [thread overview]
Message-ID: <20240425171311.19519-1-ricardo.neri-calderon@linux.intel.com> (raw)
Hi,
Here is v2 of the patchset to use model-specific bitmasks to read TCC
offset and the digital temperature readout of IA32_[PACKAGE]_THERM_STATUS.
You can read the cover letter of v1 here [1] for details.
Changes since v1:
* Dropped dependency on CONFIG_INTEL_TCC for the coretemp driver.
Instead, extend the bitmask to 0xff to accommodate recent processors.
(Bit 23 of IA32_[PACKAGE]_THERM_STATUS is likely to be zero in less
recent processors.)
* Renamed TCC_FAM6_MODEL_TEMP_MASKS as TCC_MODEL_TEMP_MASKS.
* Renamed get_tcc_offset_mask() as intel_tcc_get_offset_mask().
* Do not export intel_tcc_get_temp_mask() as it is no longer used
outside intel_tcc.c
* Dropped stub functions for digital temperature readout and TCC
offset. They are not needed as users select CONFIG_INTEL_TCC.
I have tested these patches on Alder Lake, Meteor Lake, and Grand Ridge
systems.
These patches apply cleanly on top of the `testing` branches of the
linux-pm and hwmon repositories.
Thanks and BR,
Ricardo
