On the large servers, I/O port resource may not be assigned to all the PCI devices since it is limited (to 64KB on Intel Architecture[1]) and it may also be fragmented (I/O base register of PCI-to-PCI bridge will usually be aligned to a 4KB boundary[2]). If no I/O port resource is assigned to devices, those devices do not work. [1] Some machines support 64KB I/O port space per PCI segment. [2] Some P2P bridges support optional 1KB aligned I/O base. Therefore, I made a patch for MegaRAID SAS driver to make PCI legacy I/O port free. I have also tested the patch and it had no problem. The way to make PCI legacy I/O port free is the same as Fusion-MPT driver's and it has been merged into 2.6.30.4. This has already been fixed in e1000 and lpfc. As a result of the above, the driver can handle its device even when there are a huge number of PCI devices being used on the system and no I/O port region assigned to the device.
