FreeBSD on recent Xeon E5

[Arnaud Lacombe]

Hi,

I just booted FreeBSD 9.0-RELEASE on a Xeon E5-1650 based platform. It
would seems that the CPU handles by itself a lots of PCI functions
which do not seem to be supported by FreeBSD. Here is the output of
`pciconf -l' restricted to unhandled devices:

These would seem to correspond to Uncore feature, namely, as per [0]:

0x3C20 - 0x3C3F: IO Features (QDDMA, APIC, Intel VT, RAS, Intel TXT)
0x3C40 - 0x3C5F: Performance Monitors
0x3C60 - 0x3C7F: DFX
0x3C80 - 0x3C9F: Intel QuickPath Interconnect
0x3CA0 - 0x3CBF: Home Agent/Memory Controller
0x3CC0 - 0x3CDF: Power Management
0x3CE0 - 0x3CFF: Cbo/Ring

Even if it would not seem to be critical features, what will be the
consequence of having those features currently unhandled ?

Thanks,
