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
Message-Id: <20240425171311.19519-1-ricardo.neri-calderon@linux.intel.com>

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
