tools/power turbostat: Use standard Energy Unit for SPR Dram RAPL domain2022-10-04T21:00:02ZZhang Ruirui.zhang@intel.com2022-09-24T05:47:38Zurn:sha1:b2d433ae637626d44c9d4a75dd3330cf68fed9de
Intel Xeon servers used to use a fixed energy resolution (15.3uj) for
Dram RAPL domain. But on SPR, Dram RAPL domain follows the standard
energy resolution as described in MSR_RAPL_POWER_UNIT.
Remove the SPR rapl_dram_energy_units quirk.

tools/power turbostat: Do not dump TRL if turbo is not supported2022-10-04T20:59:55ZArtem Bityutskiyartem.bityutskiy@linux.intel.com2022-09-16T11:59:50Zurn:sha1:3ea8e52ec94de6cd5e8a9dc7b2ec72a7745b4e47
Do not dump turbo ratio limits if platform does not support turbo, because it
is confusing and the TRL MSRs may even include misleading information. And they
are not supposed to be relied on if turbo is not supported.

Add turbostat support for RAPTORLAKE_S platform, which behaves the same
as RAPTORLAKE and RAPTORLAKE_P platforms.
RPL-S 601/801 have different CPU ID than the Hybrid ADL-S platforms.

tools/power turbostat: do not decode ACC for ICX and SPR2022-07-28T18:37:41ZArtem Bityutskiyartem.bityutskiy@linux.intel.com2022-07-26T15:29:35Zurn:sha1:6287e6f0fdd36be4bbde6f539df6ea85eb2476c2
The ACC (automatic C-state conversion) feature was available on Sky Lake and
Cascade Lake Xeons (SKX and CLX), but it is not available on Ice Lake and
Sapphire Rapids Xeons (ICX and SPR). Therefore, stop decoding it for ICX and
SPR.

tools/power turbostat: fix SPR PC6 limits2022-07-28T18:37:29ZArtem Bityutskiyartem.bityutskiy@linux.intel.com2022-07-26T15:29:34Zurn:sha1:0e4d42af81471ab801e059e1feac8e27547230cf
Sapphire Rapids Xeon (SPR) supports 2 flavors of PC6 - PC6N (non-retention) and
PC6R (retention). Before this patch we used ICX package C-state limits, which
was wrong, because ICX has only one PC6 flavor. With this patch, we use SKX PC6
limits for SPR, because they are the same.

The 'automatic_cstate_conversion_probe()' function has a too long 'if'
statement, convert it to a 'switch' statement in order to improve code
readability a bit.

tools/power turbostat: separate SPR from ICX2022-07-28T18:37:10ZArtem Bityutskiyartem.bityutskiy@linux.intel.com2022-07-26T15:29:32Zurn:sha1:684e40e99e594e0da1dc1b358fbd51c03c606e75
Before this patch, SPR platform was considered identical to ICX platform. This
patch separates SPR support from ICX.
This patch is a preparation for adding SPR-specific package C-state limits
support.
