Title: VoodooPS2Keyboard: unexpected acknowledge PS2Controller
Post by: dungbx on April 11, 2009, 06:57:52 PM
Hi Voodoo.

At first I want to say thanks to the team for considering to fix this old technology.
It's long time I've been waiting for the kext. I even tried to fix source code but...

Okay, this is my problem:
I installed VoodooPS2 and restart.
At boot it said: "VoodooPS2Keyboard: unexpected acknowledge PS2Controller" repeatly and doesnt stop.

Some history about my laptop:
Quote
Leopard 10.5.5 Voodoo Kernel
HP Pavilion DV6205/CT Japanese Keyboard
AMD 1.6GHz Turion64X2
1GB RAM
80GB HDD nForce4 SATA (works, Medevil)
nVidia Geforce 7200 Go (works 100%, NVKush)
Connexant HID sound (works, AzaliaAudio, speakers only)
Broadcom Wifi (works oob)
nForce Network Controller (works, nForce LAN)

PS/2 Keyboard +Trackpad sometimes work

Previously I've tried many PS2 kext but never work.
Since Tiger 10.4 until now Leo 10.5.5. Just sometimes keyboard & touchpad work.

Please take a look at this.
Best regards.

Hello.

Can I ask for a debug version of this kext?
Maybe it will help.

I installed VoodooPS2 and restart.
At boot it said: "VoodooPS2Keyboard: unexpected acknowledge PS2Controller" repeatly and doesnt stop.

Code: [Select]
void ApplePS2Keyboard::interruptOccurred(UInt8 scanCode)   // PS2InterruptAction
{
    //
    // This will be invoked automatically from our device when asynchronous
    // keyboard data needs to be delivered.  Process the keyboard data.  Do
    // NOT send any BLOCKING commands to our device in this context.
    //

    if (scanCode == kSC_Acknowledge) // 0xFA
        IOLog("%s: Unexpected acknowledge from PS/2 controller.\n", getName());
    else if (scanCode == kSC_Resend)
        IOLog("%s: Unexpected resend request from PS/2 controller.\n", getName());
    else
        dispatchKeyboardEventWithScancode(scanCode);
}

Above function is a keyboard interrupt handler.

That you saw the log message, it means ps/2 kext passed init() and prove() function well.

Code: [Select]
bool ApplePS2Keyboard::start(IOService * provider)
{
 ...
    //
    // Reset and enable the keyboard.
    //

    initKeyboard();

    //
    // Install our driver's interrupt handler, for asynchronous data delivery.
    //

    _device->installInterruptAction(this,
            OSMemberFunctionCast(PS2InterruptAction,this,&ApplePS2Keyboard::interruptOccurred));
    _interruptHandlerInstalled = true;

    //
    // Install our power control handler.
    //

    _device->installPowerControlAction( this,
            OSMemberFunctionCast(PS2PowerControlAction,this, &ApplePS2Keyboard::setDevicePowerState ));
    _powerControlHandlerInstalled = true;

    return true;
}

I don't know well, but I guess there are some mis-initializing or other problem in start() function.

Thank you for that information.
I've been looking into the code but it's kind of pointless.

The same problem was found in very previous PS2 kext...
I guess it must be about ACPI. Its behavior is really weird :(
