    摘要: Apparatus and method for a first device to query a second device for the availability of a hardware feature within the second device, and for the second to receive and analyze the query to determine whether or not to respond, depending on the version of hardware feature sought, a code identifying a vendor, etc., and responding with a reply providing an indication of availability of the hardware feature and/or an address at which the hardware feature may be accessed, if the determination is made to reply.

    摘要: An apparatus and method for outbound I/O write-combining are described. In one embodiment the method includes the detection of a write transaction request directed to an I/O device. Once detected, it is determined whether an address associated with the detected write transaction falls within a predetermined write-combinable range of the memory mapped I/O space assigned to the I/O device. When the transaction address falls within a write-combinable range, data associated with the detected write transaction is stored within a buffer corresponding to the transaction address. Accordingly, one embodiment of the present invention provides write-combining for data written to an I/O port associated with a memory mapped I/O address space.
