The Intel Platform Controller Hub for Intel Core SoCs provides access
|
||
|
|
to Power Management Controller registers via various interfaces. This
|
||
|
|
driver can utilize debugging capabilities and supported features as
|
||
|
|
exposed by the Power Management Controller. It also may perform some
|
||
|
|
tasks in the PMC in order to enable transition into the SLPS0 state.
|
||
|
|
It should be selected on all Intel platforms supported by the driver.
|
||
|
|
|
||
|
|
Supported features:
|
||
|
|
- SLP_S0_RESIDENCY counter
|
||
|
|
- PCH IP Power Gating status
|
||
|
|
- LTR Ignore / LTR Show
|
||
|
|
- MPHY/PLL gating status (Sunrisepoint PCH only)
|
||
|
|
- SLPS0 Debug registers (Cannonlake/Icelake PCH)
|
||
|
|
- Low Power Mode registers (Tigerlake and beyond)
|
||
|
|
- PMC quirks as needed to enable SLPS0/S0ix
