Hi,
With the following code the Sleep and Eject routines work better.
When I ask for eject my card, with the eject menu bar, I have the following trace :
message() : card services event CS_EVENT_EJECTION_REQUEST
message() : card services event CS_EVENT_CARD_REMOVAL
IOPCCard: shutting down socket 0.
IOPCCard: calling terminate on socket 0 function 0 nub 0x18f2d00.
stop() : * STOP (myAudioDevice) 0x18f2d00
free() : * FREE (myAudioDevice)
When I insert my card :
IOPCCard16Device: binding socket 0 function 0 to card services.
initHardware() : * INIT HARDWARE (myAudioDevice)
But when I go to Sleep state and I Eject my card I did not receive the CS_EVENT_CARD_REMOVAL event.
What could I do when the computer is wake up ?
What can I do to call "IOPCCard: shutting down socket 0".
IOReturn
myAudioDevice::performPowerStateChange(IOAudioDevicePowerState oldPowerState,
IOAudioDevicePowerState newPowerState,
UInt32 *microsecondsUntilComplete)
{
...
// ******************************************
// WAKE UP
// ******************************************
if( oldPowerState == kIOAudioDeviceSleep )
{
// ******************************************
// PCCard is present
// ******************************************
if( nubPCCard16Device->getState() == (DEV_CONFIG | DEV_PRESENT) ) {
....
// Reinitialize
...
// ******************************************
// PCCard is not present
// ******************************************
} else {
DOUT( DBG_POWER_MODE, ("%s() : The card was removed while sleeping \n", __FUNCTION__ ));
// What can I do in this case ???
// I try the following function, but It does not wake up ...
scheduleStop( nubPCCard16Device ); // Call Stop and Free
}
}
...
return result;
}
IOReturn
myAudioDevice::message( UInt32 type, IOService * provider, void * argument )
{
...
switch(type) {
case kIOPCCardCSEventMessage: {
case CS_EVENT_EJECTION_REQUEST:
DOUT( DBG_POWER_MODE, ("%s() : card services event CS_EVENT_EJECTION_REQUEST.\n", __FUNCTION__ ));
case CS_EVENT_CARD_REMOVAL:
DOUT( DBG_POWER_MODE, ("%s() : card services event CS_EVENT_CARD_REMOVAL.\n", __FUNCTION__ ));
case CS_EVENT_EJECTION_COMPLETE:
DOUT( DBG_POWER_MODE, ("%s() : card services event CS_EVENT_EJECTION_COMPLETE.\n", __FUNCTION__ ));
}
}
...
return kIOReturnSuccess;
}
Thanks in advance for all replies...
