Hi all, today I finally got my hands on the user interrupts for plain 68000 CPUs and it was quite straightforward, just as you have suggested: I implemented user*_inthandlers in entry_mm.S that push the vectornumber onto the stack. My kernel still doesn't boot completely, but it runs now correctly calibrate delay loop (0.59 BogoMIPS, isn't it great? ;) since the timer interrupt is working.
0.6 BogoMIPS sounds about right :-)
According to the "release early, release often"-mantra, I want now to send some patches to the list. Do you want to have the Atari bootstrap patches in this mailinglist? I'm asking because bootstrap is not (anymore) part of the kernel sources... The next question would be whether you want to have a single head.S version for the Atari ST-nommu platform or a merge with the current arch/m68k/kernel/head.S. The head.S I use does not use much code from the "classic" head.S and is for sure easier to read due to its small size.
Regarding the bootstrap patches - do send them to the list, please. Whoever does build ataboot binaries occasionally these days can then pick up your patches. ataboot used to be part of the m68k CVS on kullervo.debian.net but we have had to take kullervo offline half a year ago. Christian has rebuilt the system but we're still having trouble with the ethernet driver in 3.1 (sort of working on this). I'm sure we can clone the m68k CVS off kullervo and set it up somewhere else. My preference would be to have a separate head.S if they cannot be trivially merged. Your call, or Geert's really though. Cheers, Michael -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
