Detailed Description
Low Power Idle (LPI) structure with Native C-state instruction entry trigger descriptor
Member Data Documentation
◆ EntryTrigger
| EFI_ACPI_6_1_GENERIC_ADDRESS_STRUCTURE ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::EntryTrigger |
The LPI entry trigger, matching an existing _CST.Register object, represented as a Generic Address Structure. All processors must request this state or deeper to trigger.
◆ Flags
| ACPI_LPI_STATE_FLAGS ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::Flags |
LPI state flags.
◆ Latency
| UINT32 ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::Latency |
Worst case exit latency in uSec.
◆ Length
| UINT32 ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::Length |
Length of LPI state Descriptor Structure
◆ Reserved
| UINT8 ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::Reserved[2] |
Must be Zero.
◆ Residency
| UINT32 ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::Residency |
Minimum residency or break-even in uSec.
◆ ResidencyCounter
| EFI_ACPI_6_1_GENERIC_ADDRESS_STRUCTURE ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::ResidencyCounter |
[optional] Residency counter, represented as a Generic Address Structure. If not present, Flags[1] bit should be set.
◆ ResidencyCounterFrequency
| UINT64 ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::ResidencyCounterFrequency |
[optional] Residency counter frequency in cycles per second. Value 0 indicates that counter runs at TSC frequency. Valid only if Residency Counter is present.
◆ Type
| UINT32 ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::Type |
LPI State descriptor Type 0.
◆ UniqueId
| UINT16 ACPI_LPI_NATIVE_CSTATE_DESCRIPTOR::UniqueId |
Unique LPI state identifier: zero based, monotonically increasing identifier
