    摘要: A computer system that includes at least two host agents is provided. The computer system further includes a chipset that includes a resource to be shared by the at least two host agents. The chipset is coupled to the-at least two host agents. The chipset prevents a first host agent, that occupies the shared resource to access the shared resource until a second host agent, has made progress in accessing said shared resource.

    摘要: A computer system that includes a host processor (HP), a system memory (SM), and a host bridge coupled to the HP and SM is provided. The host bridge asserts a first read request to the SM and, prior to availability of snoop results in connection with the first read request, the host bridge asserts a following second read request to the SM.

    摘要: For isochronous data steams processed by a computer system, for example high definition audio streams, embodiments keep track of the free space available in the input and output buffers for the data streams. The available free space in the buffers determines whether various low power entry and exit thresholds are met or not. If all low power entry thresholds are met, then various circuits such as clocks, phase locked loops, and direct media interface links, may be put into a low power state, and the data stream controller enters an idle window so that memory requests are not serviced. During this time, system DRAM may begin refresh. Once the low power state has been entered into, if any exit threshold is met, then the low power state is ended. Other embodiments are described and claimed.

    摘要: A method to deterministically shut down memory devices in response to a system warm reset has been disclosed. One embodiment of the method includes causing a first type of reset in a number of memory devices in a system in response to a second type of reset in the system being initiated if the memory devices are not initialized and enabling a deterministic shutdown mode in a memory controller, which is coupled to the memory devices, after the memory devices have been initialized. Other embodiments are described and claimed.

    摘要: A combination of techniques to prevent deadlocks and livelocks in a computer system having a dispatcher and multiple downstream command queues. In one embodiment, a broadcast transaction that requires simultaneously available space in all the affected downstream command queues becomes a delayed transaction, so that the command queues are reserved and other transactions are retried until the broadcast transaction is completed. In another embodiment, a bail-out timer is used to defer a transaction if the transaction does not complete within a predetermined time. In yet another embodiment, a locked transaction that potentially addresses memory space controlled by a programmable attribute map is handled as a delayed transaction if there is less than a predetermined amount of downstream buffer space available for the transaction.

    摘要: A method and apparatus for delivering APIC interrupts to a processor, and between processors, as FSB transactions. Interrupts and hardware signals, generated by a PCI device, are converted into an upstream memory write interrupt and further converted into an FSB interrupt transaction, received by a processor. Interrupts marked as lowest priority re-directable are redirected based on task priority information. Support for XTPR transactions to update XTPR registers is provided. Preferred ordering of XTPR update transactions and interrupts to be redirected is provided.
