I am interested in considering this tool for a PCI Express driver for Linux and Windows (XP & Vista). I need some brief feedback in the following areas:
Thanks for any feedback!
Well I have not looked at Jungo for quite a while, but in the past I got a
ton a queries as a consiltant to “add a little feature to a Jungo driver”
well it turned out the framework could not support the feature. This
happened many times for many clients, I did quotes to replace a lot of
Jungo. Asl Jungo if they support MSI interupts in Windows, whether they
support WPP tracing, etc.

On the other side, I have a lot of people come to me with the same “add
a feature to a Jungo driver for Linux” type of requests which requires
the same massive rework and eventually they do the same as you mention.
The legal status of the Jungo Linux portion is also quite murky, so you
might want to watch out for that (or at least have your lawyers go over
it very closely.)
Good luck,

I would never ever use this tool. Use KMDF for Windows.
Linux port will require massive amount of work - all OS interaction is
different, only the logic related to your hardware can be ported.

I have never used this product, nor have I ever heard any direct
testimony about it, nor, for that matter, have I ever or likely will
write a driver for a PCI/PCI-e device, unless I change focus in a big
way. I’m just curious as to how well it performs, how the claim of a
single source code base pans out, and, in particular, if they hold
together for an arbitrary PCI/PCI-e device. A cross platform user mode
driver framework that offers great performance across a single source
code base, supports all PCI/PCI-e devices and does not require any OS
specific knowledge, kernel programming techniques or even use of kernel
debugger seems rather unlikely to work as advertised in any realistic
scenario requiring production quality drivers that will go on to be
supported outside of the lab, that it apparently has a bunch of Wizards
notwithstanding.
This isn’t an accusation; I’m just curious, as on the one hand, I can’t
quite shake my prejudice against products that sound like this, but on
the other there haven’t been any comments along the lines of what anyone
who posts on this list would expect had the dev asked about, say,
DriverWorks. Certainly, DriverWorks was (always) a complete piece of
shit, but it’s goals were also much less ambitious than those of this
product.
