Sure, I attach devinfo with -rv, -r and -u.
Question: I don't know how the acpi subsystem works, but on my naive
thinking, the acpi subsystem scans the acpi tables and populates the
entries in the device tree, setting aside the address ranges (IO and mem)
for which there is no driver. The handle items in the tree (e.g.
\_SB_.PCI0.LPCB.GMUX) look very similar to the ones in the acpi tables. So
I thought the driver then later claims these resource using the
bus_alloc_resource(). Is this true at all?
By the way, devinfo -r shows nexus0 as the root device, but in devinfo -u
there's root0, which does not show up in devinfo -r. Is this how it should
be?
Thanks again
Peeter
