You should enjoy powerful mdb & dtrace, which are what I want on Linux :)
bash# mdb -k
> ::log /var/your-outputs
> *pci_bus_res ::print struct pci_bus_resource mem_space | ::list
struct memlist next | ::print struct memlist
And then, check the file /var/your-outputs

I would like to print the PCI resources when the driver attach entry point is
being code. Could anyone show me where is this information in the dev_info
structure?
It seems that the PCI bus drivers does not correctly enumerate the device
object system resources during boot time, when the driver loads it gets
erroneous system resources in the dev_info:
ttp://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/intel/io/pci/pci_boot.c#2159
2027 base = (uint_t)memlist_find(io_res, len, len);
2028 if (base != 0) {
2029 memlist_insert(io_res_used, base, len);
2030 /* XXX need to worry about 64-bit? */
2031 pci_putl(bus, dev, func, offset,
2032 base | type);
2033 base = pci_getl(bus, dev, func, offset);
2034 base &= PCI_BASE_IO_ADDR_M;
2035 }
2036 if (base == 0) {
2037 cmn_err(CE_WARN, "failed to program"
2038 " IO space [%d/%d/%d] b...@0x%x"
2039 " length 0x%x",
2040 bus, dev, func, offset, len);
Thanks,
Eitan
