Abstract
Various embodiments are directed to creating multiple device blocks associated with hardware devices, arranging the device blocks in an order indicative of positions of the hardware devices in a hierarchy of buses and bridges, and enabling access to the multiple device blocks from an operating system. An apparatus comprises a processor circuit and storage storing instructions operative on the processor circuit to create a device table comprising multiple device blocks, each device block corresponding to one of multiple hardware devices accessible to the processor circuit, the device blocks arranged in an order indicative of relative positions of the hardware devices in a hierarchy of buses and at least one bridge device; enable access to the device table by an operating system; and execute a second sequence of instructions of the operating system operative on the processor circuit to access the device table. Other embodiments are described and claimed herein.

31. An apparatus comprising:
-
a processor; and logic, at least partially implemented by the processor, the logic to; generate a device table comprising a plurality of device blocks, each device block corresponding to one of multiple devices, the device blocks arranged in a hierarchal order within the device table to indicate relative positions of the devices such that a device block corresponding to a core device of the multiple devices precedes all other device blocks; and load multiple device drivers for the multiple devices in an order that follows the order of the device blocks. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)

39. A computer-implemented method comprising:
-
generating a device table comprising a plurality of device blocks, each device block corresponding to one of multiple devices, the device blocks arranged in a hierarchal order within the device table to indicate relative positions of the devices such that a device block corresponding to a core device of the multiple devices precedes all other device blocks; and loading multiple device drivers for the multiple devices in an order that follows the order of the device blocks. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46)
