tisci_msg_lpm_set_latency_constraint_req Struct Reference

Detailed Description

Request for TISCI_MSG_LPM_SET_LATENCY_CONSTRAINT.

Parameters

hdr	TISCI header to provide ACK/NAK flags to the host.
resume_latency	The maximum acceptable latency to wake up from low power mode in milliseconds. The deeper the state, the higher the latency.
state	The desired state of constraint: set or clear.
rsvd	Reserved for future use.

This message is used by host to set latency for waking up from low power mode. This can be sent anytime after boot before prepare sleep message and after current low power mode is exited. Any host can set a constraint on the low power mode that the SoC can enter. It allows configurable information to be easily shared from the application, as this is a non-secure message and therefore can be sent by anyone. By setting a wakeup latency constraint, the host ensures that the resume time from selected low power mode will be less than the constraint value.
