Re: PCI 2.x devices not supported by QNX 7.0

Absolutely no one said that!!

As you probabbly know there are older and newer PCI standards.

The issue is here the support of the older PCI 2.x standard. There is a huge installed base in the field of industrial 
applications.

And yes ...  PCIe is well supported. It's just the crazy decision not to support PCI 2.x  which makes huge problems iin 
the INDUSTRY.

Hi Armin,

Can you please be more specific as to what problems you are seeing?

I can assure you that other than our decision to not support Cardbus, there was no deliberate attempt to restrict the 
use of any hardware to a specific specification revision.
Is Cardbus the issue?

Regards,
Mike

Hi Mike,

yes, the problem are the "old" PCI2.x cards. Please have a look to the different screendumps for QNX 6.5 and QNX 7.0 ...
 they are attached.

Armin

Ok ... in order to support 32-bit PCI 2.x adapter for QNX 7.0 I'm going to develop my own  64-bit PCI server.
It will be just a standard resource manager dealing only with 32-bit PCI card bus adapter.

First results are attached ... it's the 64bit version of lspci ... its code base could be the base for the PCI server.
