XIO2001: pci-to-pci bridge disappears from PC Device Manager follow up

Part Number: XIO2001

Hi Nasser,

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1091227/xio2001-pci-to-pci-bridge-disappears-from-pc-device-manager

follow up.

The customer also request technical support from DELL.

He has a small question, can you confirm it?

I used RW-everything when confirming XIO2001,
Is there a way to confirm the register setting of this IC without tools?

In device manager or other windows standard features,
I would like to confirm that the ASLPMC item has become an 'active state PM disabled' configuration.

Thanks a lot.

    Hi Frank,

    The only available software that i am aware of is a utility called XIO2001 performance tuner. This ran under window XP, Vista, and 7. However, this is too old and there is no support for this utility.

    Hi Nasser,

    Thank you for respond this thread.

    I try to use XIO2001 performance tuner,
    it unable to confirm the address 0x80.
    Is there any way to confirm the setting of the register of XIO2001 only by using the windows standard function?
    If not, it doesn't matter.

    In addition, the change of BIOS ASPM setting using Dell Optiplex7090 is not reflected in the XIO2001 register,

    Can I consider it's the problem of DELL BIOS?

    Thanks.

    Hi Frank,

    There is not a way to confirm the setting without tools.  The XIO2001 and any other PCIe device is accessed through what is called the PCI Configuration Space.  It is a set of registers that is defined by the PCIe specification.  It is also shown in the XIO2001 datasheet.  To access these registers on any Operating System you will need a driver.  It sounds like from the previous post that a driver is already being used for the XIO2001.  Software must utilize this driver in order to investigate the PCIe configuration space of the XIO2001.

    These types of tasks are usually handled by the BIOS or the Operating System software engineers.  The XIO2001 driver doesn't disappear anymore after changing the ASPM setting correct?  

    Thanks,

    Nicholaus
