A few weeks ago I came across a set of books from MindShare, Inc. that proved to be absolute lifesavers during my latest round of LinuxBIOS hacking. It takes some careful reading to extract the bits that are relevant to BIOS programming, but they go a long way towards demystifying PCI device configuration, interrupt routing, and HyperTransport configuration.
* PCI System Architecture * HyperTransport System Architecture * Opteron Processors: Breaking Tradition (excerpt from upcoming book on AMD K8 Processor Architecture)
I didn't see them referenced on the LinuxBIOS web site; would anyone object to adding these to the Documentation page?
Also, let me state for the sake of future poor souls:
LDT means HyperTransport. LDT means HyperTransport. LDT means HyperTransport. LDT means HyperTransport.
That is all.
