Abstract: An interface of a device is used to couple to another device and includes a set of data pins to support high speed data communication on an interconnect link between the devices based on an interconnect protocol. The interface further includes at least one auxiliary pin to support a particular signal defined by the interconnect protocol. The device is further configurated to generate hint data for use by the other device and send the hint data as a sideband signal to the other device over the auxiliary pin, where the sideband signal is distinct from signals defined for the auxiliary pin by the interconnect protocol.

Abstract: Methods and apparatus for optimizing device power and efficiency based on host-controlled hints prior to low-power entry for PCI Express blocks and components. Data structures containing low-power state capability information mapping one or more fine-grained low-power states for each of at least one of an L0s, L1, L1.1, and L1.2 PCIe-defined low-power state are stored on a PCIe device coupled to a Host via a PCIe link. Messages are exchanged over the PCIe link between the Host and PCIe device to configure, using the low-power state capability information, blocks and/or components on the PCIe device to enter a fine-grained low-power state instead of an associated PCIe-defined low-power state mapped to the fine-grained low-power state when the PCIe device detects a power-change event or receives a command to enter the associated PCIe-defined low-power state. Sequences of power-level changes between multiple fine-grained low-power states may also be implemented.

Abstract: A device connected by a link to a host system can include a first port to receive a capability configuration message across a link and a message request receiving logic comprising hardware circuitry to identify a capability of the device identified in the capability configuration message, determine that the capability is to be presented or hidden from operation based on a capability hide enable bit in the capability configuration message, and configure a capability linked list to present or hide the capability based on the determination. The device can also include a message response generator logic comprising hardware circuitry to generate a response message indicating that the capability is to be presented or hidden from operation. The device can include a second port to transmit the response message across the link.

Abstract: A handshake communication mechanism between a host and an end-point device permits multiple Base Address Registers (BAR registers) to be configured to size or resize the mapped address spaces associated with each BAR register. In one embodiment, the handshake communication mechanism includes a single address space reconfiguration request which may be transmitted in a single transaction layer packet, to request the configuration of multiple BAR registers of an end-point device. Other features and advantages may be realized, depending upon the particular application.

Abstract: Systems and devices can include a power management controller to determine a low power mode exit timing from a plurality of low power mode exit timing options, and cause the setting of a low power mode control register based on the determined low power mode exit timing. A message generator can generate a power mode request message. The power mode request message indicating the determined low power mode exiting timing. The power mode request message can be transmitted to a host across a multilane link.
