    Subject[PATCH 6.0 657/862] tools/power turbostat: Use standard Energy Unit for SPR Dram RAPL domain
    Date
    From: Zhang Rui <rui.zhang@intel.com>

    [ Upstream commit 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.
