    Remove proc_root export. Creation and removal works well if parent PDE is
    supplied as NULL -- it worked always that way.

    So, one useless export removed and consistency added, some drivers created
    PDEs with &proc_root as parent but removed them as NULL and so on.

  • 217f6710c   m68k: Mac IRQ cleanup ... Browse Code »

    There are no slow IRQs on Macs since Roman Zippel's IRQ reorganisation that
    went into 2.6.16 and removed mac_irq_list[] and the do_mac_irq_list()
    dispatcher. (They were implemented in do_mac_irq_list() by lowering the IPL.)
    Hence there's no more use for mutual exclusion in the Mac interrupt
    dispatchers. Remove it.

  • cd713ddc9   m68k: Mac nubus IRQ fixes (plan E) ... Browse Code »

    Some Macs lack a slot interrupt enable register. So the existing code makes
    disabled and unregistered slot IRQ lines outputs set high. This seems to work
    on quadras, but does not work on genuine VIAs (perhaps the card still succeeds
    in pulling the line low, or perhaps because this increases the settle time on
    the port A input, meaning that the CA1 IRQ could fire before the slot line
    reads active).

    Because of this, the nubus_active flags were used to mask IRQs, which is
    actually worse than the problem it tries to solve. Any interrupt masked by
    nubus_active will remain asserted and prevent further transitions on CA1. And
    so the nubus gets wedged regardless of hardware (emulated VIA ASIC, real VIA
    chip or RBV).

    The best solution to this hardware limitation of genuine VIAs is to disable the
    umbrella SLOTS IRQ when disabling a slot on those machines. Unfortunately, this
    means all slot IRQs get disabled when any slot IRQ is disabled. But it is only
    a problem when there's more than 1 device using nubus interrupts.

    Another potential problem for genuine VIAs is an unregistered nubus IRQ.
    Eventually it will be possible to enable the CA1 interrupt by installing its
    handler only _after_ all nubus drivers have loaded but _before_ the kernel
    needs them, at which time this last problem can be fixed. For now it can be
    worked around:

    - disable MacOS extensions
    - don't boot MacOS (use the Emile bootloader instead)
    - get the bootloaders to disable ROM drivers (Penguin does this for video
    cards already, don't know about Emile)
    - physically remove unsupported cards

  • 67dfb153a   m68k: Mac IRQ prep ... Browse Code »

    Make sure that there are no slot IRQs asserted before leaving the nubus
    handler. If there are and we don't then the nubus gets wedged because this
    prevents a CA1 transition, which means no more nubus IRQs.

    Make the interrupt dispatch loops terminate sooner.

    Explicitly initialise the VIA latches to make the code more easily understood.

    Also some cleanups.

    m68k_handle_int() split in two functions: __m68k_handle_int() takes
    pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs
    *.

    Places where we used to call m68k_handle_int() recursively with the same
    pt_regs have simply lost the second argument, the rest is switched to
    __m68k_handle_int().

    The rest of patch is just dropping pt_regs * where needed.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
