BIOS & Interrupt Functions

Which version of BIOS are you using?

OK, thank you, one additional question:

The C6748 has a dual module interrupt initialization.

From one side I need to initialize interrupt controller which in-build into CPU. Most of the programming of that done in protected mode,
in assembly. BIOS has such a routines I am using. I have this part of interrupt is working, I even see it in debugger. Example you send me exactly about this part.

Another part of hardware interrupt is initialization of event interrupt controller working in Mega-Module of the same C6748 chip. I able to allocate resources for that, I am also trying to do in manually with the register settings. Functions of BIOS for that should be also presented as well.

They supposed to look like this event_enable(7,94,flag) for example where 7 is hardware interrupt of processor and 94 is enable line of mega-module.It is attach  hardware line of mega-module peripheral interrupt to CPU interrupt, and this particular example may allow to work UPP interrupt.

Please advise.

All BIOS functions are documented in the BIOS API Guide.  See the HWI functions...

I am looking for HWE or event functions, not HWI, and I did not find even such chapter in BIOS API guide.  Please let me know and thank you.

Paul,

You mentioned the "event interrupt controller".  I do not know what that is.  I already told you about the  HWI APIs.  Those are the APIs that configure the interrupt controller that is inside the megamodule.  The only other thing I can think of is the "Event Combiner" which is a feature of the interrupt controller.  We have the ECM APIs for this purpose.

If that does not answer your question please use the exact names from the documentation  because I am having great difficulty understanding what you're asking.  Please cite literature numbers as well as relevant tables, figures, pages, etc.  to help me understand your question.

As you mentioned, what I am looking for most probably is ECM API or "event combiner" API.

This part is not mentioned in BIOS API, thank you.

Brad:

Can you send me the link to the ECM API Chapter you are referencing in your last e-mail.  Also the customer seems to be unable to get the EMAC interrupt all the way to the processor.  For some reason the customer has to poll one of the register sets, I believe it is in the ECM, to figure out if anything has happened.  Can you point me to the proper document or WIKI that describes what they have to do to finish this final piece of our EMAC code?

The link is in my March 15th post.

ok thanks, In section 2.7, it keeps talking about the C64x+ Interrupt Controller.  IS there any difference between this and the interface to the interrupt controller in the C674x?

The 64x+ and 674x interrupt controllers are identical.

Sorry, I meant to ask about the event controller.

There was some discussion that it is not supported by the bios and that it is not the same as the c64 event controller.  Please let me know and thank you for the support.
