I have a legacy FSFD that I ported to x64 using WDK6000. Now a client needs
it for an Itanium machine. I assume I have to rebuild for IA64, but is there
anything else I need to do besides just rebuild it? I.e., does any code
need to change? Thanks.
I don’t think there will be any code changes required.
Try to build it in the same environment what you are thinking.

Hi!
Just in case you are communicating with your user mode application, just
make sure that the buffer alignment is correct.
I think alignment is different in IA64. Go through Minispy example.

I haven’t done a Windows driver on Itanic, but alignment requirements are a
lot tighter. Don’t know if some of the memory barrier stuff will hit you or
whether the DDK API’s take care of all of it.
Expect a lot larger driver since IA64 is so space inefficient, so things
like .kdfiles can be a pain. Also, if you are a small shop see if you can
even take an Itanic, many of them have power requirements that won’t work
wirhout rewiring (something I learned in a possible Itanic driver project).

The Itanium system that I used in a project did not have any special power
requirements.

I didn’t have to anything special but the driver was a very simple one. It
did not talk to hardware.

Itanium has mandatory alignment requirement, not like x64 and x86.

Strange. The usual European-style power outlet can easily feed 2Kw on 220V.
How many watts must an Itanium computer consume to require rewiring?

Max,
More than once I was told 220 40AMP, these were servers but that is
what the customer wanted. Of course when I quothed them the bill, they
decided not to. Fortunately the only people who seem to want drivers for
Itanic are being paid by Intel to have their product on this beast.

Which would answer the question I was about to post: who wants to run on
these systems and why.

Hi!
Just to add to Maxim’s reply, here is a statement from “Checklist for 64-bit
Microsoft Windows Drivers”:
Itanium-based systems require natural alignment for memory references (that
is, 32-bit accesses at a 4-byte boundary). Misaligned memory references
raise an exception on an Itanium-based system and bug check the system.
Alignment is required for x64 support to obtain better performance, although
x64 is more forgiving.
Regards,
Ayush Gupta
What is the likelihood, if any, that a driver built for x64 will run on an
Itanium system? Zero? Thanks.
