  • We used to BUG_ON() for a badly mapped IO port, which is certainly
    correct, but actually made it harder to debug the case where the ATA
    drivers had incorrectly mapped a nonconnected ATA port.

    So make badly mapped ports trigger a WARN_ON(), and throw the IO away
    instead (and return all ones for reads). For things like broken driver
    initialization - which is the most likely cause anyway - that should
    mean that the machine comes up and is usable (at least that was the case
    for the ATA breakage that triggered this patch).

    It tends to be a whole lot easier to do a "dmesg" on a working machine
    than to try to capture logs off a dead one.

  • Install the built-in macsonic interrupt handler on both IRQs when using
    via_alt_mapping. Otherwise the rare interrupt that still comes from the
    nubus slot will wedge the nubus.

    $ cat /proc/interrupts
    auto 2: 89176 via2

    mac 56: 629 sonic
    mac 62: 1142593 ide0

    Version 1 of this patch had a bug where a nubus sonic card would register
    two interrupt handlers. Only a built-in sonic needs both.

    Versions 2 and 3 needed some cleanups, as Raylynn Knight and Christoph
    Hellwig pointed out (thanks).

  • Fix a race condition in the transmit code, where the dma interrupt could update
    the free tx buffer count concurrently and wedge the tx queue.

    Fix the misuse of the rx frame status and rx frame length registers: no more
    "fifo overrun" errors caused by the OFLOW bit being tested in the frame length
    register (instead of the status register), and no more missed packets due to
    incorrect length taken from status register (instead of the frame length
    register).

    Fix a panic (skb_over_panic BUG) caused by allocating and then copying an
    incoming packet while the packet length register was changing.

    Cut-and-paste the reset code from the powermac mace driver (mace.c), so the NIC
    functions when MacOS does not initialise it (important for anyone wanting to
    use the Emile boot loader).

    Cut-and-paste the error counting and timeout recovery code from mace.c.

    Fix over allocation of rx buffer memory (it's page order, not page count).

    Converted to driver model.

    Converted to DMA API.

    Since I've run out of ways to make it fail, and since it performs well now,
    promote the driver from EXPERIMENTAL status. Tested on both quadra 840av and
    660av.

  • Fix the flakiness in the CUDA ADB driver on m68k macs (keypresses getting
    wedged down or ADB just going AWOL altogether).

    The only IRQ used by this driver is the VIA shift register IRQ. The PowerMac
    conditional code disables the other VIA IRQ sources, so don't mess with the
    other IRQ flags in the common code -- m68k macs need them.

    When polling, don't disable local interrupts when we only need to disable the
    CUDA interrupt.

    Unless polling, don't clear the shift register IRQ flag. On m68k macs this
    creates a race that often breaks CUDA ADB.

    Tested on Quadra 840av and LC630 (both m68k); also Beige G3 (powerpc).

  • Fix a crash caused by requests placed in the queue with the completed flag
    already set. This lead to some ADB_SYNC requests returning early and their
    request structs being popped off the stack while still queued. Stack corruption
    ensued or an invalid request callback pointer was invoked or both. Eliminate
    macii_retransmit() and its buggy implementation of macii_write(). Have
    macii_queue_poll() fully initialise the request queues.

    Fix a bug in macii_queue_poll() where the last_req pointer was not being set.
    This caused some requests to leave the queue before being completed (and would
    also corrupt the stack under certain conditions).

    Fix a race in macii_start that could set the state machine to "reading" while
    current_req was null.

    No longer send poll commands with the ADBREQ_REPLY flag -- doing that caused
    the replies to be stored in the request buffer where they were forgotten
    about.

    Don't autopoll by continuously sending new Talk commands. Get the controller to
    do that for us. This reduces the ADB interrupt rate on an idle bus to about 5
    per second. Only autopoll the devices that were probed.

    Explicitly clear the interrupt flag when polling.

    Use disable_irq rather than local_irq_save when polling.

    Remove excess local_irq_save/restore pairs.

    Improve bus timeout and service request detection.

    Remove unused code (last_reply, adb_dir etc) and unneeded code (prefix_len,
    first_byte etc).

    Change TIP and TACK to their correct names on this ADB controller (ST_EVEN and
    ST_ODD).

    Add some commentry.

    Add a generous quantity of sanity checks (BUG_ONs).

    Let m68k macs use the adb_sync boot param too.

    Tested on Mac II, Mac IIci, Quadra 650, Quadra 700 etc.

  • 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.

  • 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

  • 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.
