hi, tiejun:
When I don't compile my pcie card driver(in kernel or as a driver), the
kernel
auto allocate the resoures to my pcie card, here is the output:
root@generic-powerpc-e500v2:~# cat /proc/ioports
00000000-007fffff : /pci@e0008000
00000000-00000fff : Legacy IO
00001000-000010ff : 0000:00:11.0
00001000-000010ff : 8139too
feffe000-ffffdfff : /pcie@e000a000
feffe000-ffffdfff : PCI Bus 0001:02
fefff000-fefff0ff : 0001:02:00.0
fefff100-fefff103 : 0001:02:00.0
the "feffe000-ffffdfff " is the resources that the kernel allocates to my
card.
