摘要： Aspects of the embodiments are directed to systems, methods, and apparatuses for controlling power management states using a clock request message across a 3.3 volt GPIO pin. Systems can include a CPU root port to transmit to a platform controller hub (PCH) compliant with a PCIe protocol, a first clock request message, the first clock request message comprising a first bit set to assert a clock request transmit (CLKREQ TX assert) on a 3.3 volt general purpose input/output (GPIO) pin local to the PCH; detect that a connected device is entering into a power management state; and transmit, from the CPU root port, to the PCH, a second clock request message, the second clock request message comprising the first bit set to deassert the clock request transmit (CLKREQ TX deassert) and a second bit to assert a clock request protocol (CLKREQ#) on a 3.3 volt GPIO pin.

摘要： Methods, apparatuses, and systems for handling transactions received after a configuration request, the method, for example, comprising: receiving a configuration change request by a transaction-handling logic block; performing a configuration change by the transaction-handling logic block in response to the configuration change request, wherein the logic block is to handle transactions received prior to receipt of the configuration change request differently than transactions received after receipt of the configuration change request; receiving, by the transaction-handling logic block, a first transaction before receiving the configuration change request; receiving, by the transaction-handling logic block, a second transaction after receiving the configuration change request and before the configuration change is complete; differentiating the first transaction from the second transaction based on the order in which the first and second transactions were received relative to receipt of the configuration change request; and handling the first and second transactions.

摘要： Embodiments of the invention describe a host system capable of associating a PCIe device and another separate device to the same device identifier (e.g., device number). A cycle routing module or logic will identify an I/O transaction involving the device identifier, and route the transaction to one or both of the devices (or, in some instances, identify the I/O transaction as a configuration transaction, and simply update the cycle routing module/logic only). In one embodiment of the invention, a root port of the host system is configured to operate as the above described cycle router.Embodiments of the invention allow for devices to be “merged” into a single device for the host OS. For example, a peripheral devices coupled to the host system via a PCIe link may be “merged” with a peripheral devices coupled to the host system via another PCIe link or a SATA link.

摘要： Particular embodiments described herein can offer a method that includes powering down a root port; initiating a first downstream cycle by a central processing unit (CPU) to the root port; identifying a power up activity for the CPU; and triggering an exit flow for a power state in conjunction with sending a second downstream cycle to the root port. In more particular embodiments, the triggering of the exit flow for the power state and the sending of the second downstream cycle to the root port occurs in a substantially parallel fashion. In addition, a prewake indicator can be sent to the root port to trigger the exit flow before the CPU is powered up and the second downstream cycle is sent.
