  • Method, apparatus, and system for power management on a CPU die via clock request messaging protocol
    Patent number: 11016549
    Abstract: 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.

  • Integrated universal serial bus (USB) type-C switching
    Patent number: 10311000
    Abstract: An apparatus is provided which comprises: an input/output (I/O) port; an adaptor; a physical layer to interface between the I/O port and the adaptor; a first controller associated with a first type of communication; and a second controller associated with a second type of communication, wherein the adaptor is to selectively couple the I/O port, via the physical layer, to one of the first controller or the second controller, based at least in part on a type of device coupled to the I/O port.
