Hi all,
How can we create a virtual PCI device from say BIOS (or is it possible). I would like to load a miniport driver for that PCI device and such would like the OS to detect that virtual PCI device.
Any hints/suggestion is much appreciated.
Thanks,
Gurpreet

Do you need a device w/out resources or do you need to have your device
enumerated and access specific resources? If it is the first one, you
don’t need the bios to enumerate a device, you can install a root
enumerated device and run your miniport on top of that.

You need to give us more details about exactly what you are trying to
accomplish. This sentence could mean several different things.
If you need your driver to access resources that were assigned to
another driver, that can be done, but not using the normal interfaces.
If you want the system to PRETEND to assign you I/O and memory
resources, as if there were a real card, there is no way to do that.
You can have your AddDevice routine allocate memory from non-paged pool
instead of mapping device memory.
Give us more details, that way we can give you reasonable advice without
wasting your time and ours.

If this is a storage miniport (scsiport/storport) it has to have resources and you should search this list as we have discussed this issue and how to implement the various hacks to get it working within the severe constraints of a virtual hba, If you mean a network miniport: I have no idea.
I think your idea of a poofed-up virtual pci device with pci resources is not going to work.

It’s more than a weird thing, it is utter nonsense. USB devices don’t
have config space. A PCI driver won’t have any idea how to communicate
with a USB device – they are accessed in entirely different ways. USB
drivers must follow the USB protocols.
If you want your miniport to talk to a USB device, you will have to
modify your miniport to send USBD requests.

No. The BIOS doesn’t “create” PCI config spaces at all. The config
space is part of each PCI device. Also, the BIOS support for USB is
extremely primitive. Most devices are not supported at all until an
operating system comes up and takes over the USB duties.

If you could write the bios, you could /maybe/ get this to work, but even if you did, that is way too much work to get this working where a simpler solution is probably there. In short, I would not pursue this further due to the complexity and tremendous amount of code that you would have to do before you could make fwd progress.

Are you saying that you want to know if a standard PC BIOS would happen to know how to essentially emulate a PCI configuration space with a specific VID/DID in response to the insertion of a specific USB device? Well, no. The PCI config space is part of the device, and doesn’t really have anything to do with the BIOS, and unless I’m missing something, this is sort of like expecting a monitor to somehow know how to emulate a disk drive, based on changing a few settings in the BIOS. . If for some reason you are hell bent on doing this, the only way I could possibly imagine this being accomplished in software at the level you wish would be to do something truly perverse, complicated, speculative, chipset specific and almost certain to fail, like emulate this sort of arrangement using the SMI, if your chipset would allow you to trap on certain IO and redirect to the SMI, which some do, but I seriously doubt that would work either.

I guess I have created some confusion but I would just like to know if there a way that the system BIOS can create a PCI Config space with specific VID/DID as soon as it sees my USB flash while the system BIOS is scanning the USB ports.

I want to expose a USB flash drive as a PCI Express device instead of a USB device where I can load my miniport driver. Once exposed, I would like to access USB flash through config space.

Gupreet, you still haven’t told us what you think the end result of your
exploration will be. You will get useful advice here when you answer the
following question:
“What makes a PCI device more interesting to you than a USB device. I.e.
why do you care what interface the OS sees?”
If your desire is for the BIOS to trigger the loading of a driver, that’s
trivial. Add a node in the ACPI BIOS with the PnP ID for your driver. The
PnP manager will pick it up (with help from the ACPI driver) and load
whatever driver your INF specifies.
If your desire is to expose a PCI device to test a future piece of similar
hardware that you want to back with your existing USB hardware, that’s
probably near impossible using the BIOS. You can come close to it with the
SMI handler in the BIOS. But the SMI handler can’t back MMIO registers and
it can’t really translate backplane-bus device usage models into packet-bus
device usage models as you would need to do moving from PCI to USB.
If your desire is to fool some piece of Windows code that expects to see a
PCI device (as in scsiport) then say so. The people here have lots of
advice on that.
We really will help if you tell us what you actually want.

Thanks Doran.
I guess I have created some confusion but I would just like to know if there
a way that the system BIOS can create a PCI Config space with specific
VID/DID as soon as it sees my USB flash while the system BIOS is scanning
the USB ports.

Needless to say, this won’t work like you want. Why hide the usb device
through pci config space at all? Just to entertain this idea, who would
simulate the config space for the device and trap the i/o to and from it?

Thanks all for replies.
I want to expose a USB flash drive as a PCI Express device instead of a USB
device where I can load my miniport driver. Once exposed, I would like to
access USB flash through config space.
May be weird thing to do but want to explore.

What specific resources do you want access to? And why? If the device does
not exist, I would think you want access to devices on the motherboard or
motherboard resources themselves…or is this to make scsiport happy and think
it has resources?

If I need the device to be enumerated and access resources, how should I go
about it.

Do you need a device w/out resources or do you need to have your device
enumerated and access specific resources? If it is the first one, you don¢t
need the bios to enumerate a device, you can install a root enumerated
device and run your miniport on top of that.

Hi all,
How can we create a virtual PCI device from say BIOS (or is it possible). I
would like to load a miniport driver for that PCI device and such would like
the OS to detect that virtual PCI device.
Any hints/suggestion is much appreciated.
Thanks,
Gurpreet
