powercap / RAPL: disable the 2nd power limit properly

2015-08-28T23:46:40Z

Let rapl_unregister_powercap() disable the second power limit only if it exists. Intel64 SDM Vol.3 14.9 says that the package domain has it but neither the power plane domain nor the DRAM domain has it. Signed-off-by: Seiichi Ikarashi Signed-off-by: Rafael J. Wysocki

powercap / RAPL: Floor frequency setting in Atom SoC

2015-05-04T22:51:22Z

CPU Floor frequency is set in BIOS for newer Atom SoCs. This patch handles configuration of floor frequency for different variants of Atom SoCs appropriately and ensures configuration of floor frequency is not done from driver for these newer Atom SoCs. Since address of the register for configuring floor frequency might change for different Atom SoCs, this patch also prevents potential overwriting of wrong registers.

powercap / RAPL: mark rapl_ids array as __initconst

2015-04-11T00:21:15Z

The RAPL ids are only tested in rapl_init() which is itself an __init function. For the MODULE_DEVICE_TABLE() file2alias doesn't care about the section, just about the symbol name. Therefore it's safe to mark the rapl_ids[] array as __initconst so its memory can be released after initialization is done. Signed-off-by: Mathias Krause Acked-by: Jacob Pan Signed-off-by: Rafael J.

powercap / RAPL: handle domains with different energy units

2015-03-13T22:18:44Z

The current driver assumes all RAPL domains within a CPU package have the same energy unit. This is no longer true for HSW server CPUs since DRAM domain has is own fixed energy unit which can be different than the package energy unit enumerated by package power MSR. In fact, the default HSW EP package power unit is 61uJ whereas DRAM domain unit is 15.3uJ. The result is that DRAM power consumption is counted 4x more than real power reported by energy counters, similarly for max_energy_range_uj of DRAM domain. This patch adds domain specific energy unit per cpu type, it allows domain energy unit to override package energy unit if non zero. Please see this document for details.
