Eh. How are you seeing those devices in the first place? My understanding is that these devices showed up on busses starting with bus 255 on down. This is managed by the qpi driver in sys/x86/pci/qpi.c. Hmm, it doesn't see any devices on my SB desktop machine here. Ah. It does a CPU ID check that needs to be updated. However, are the buses defined to be 127 and 63 rather than 255 and 254 as they were on Nehalem/Westmere? Is there formal documentation you can point me at (from Intel perhaps?) that explains the official method for discovering these PCI buses? -- John Baldwin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "[email protected]"
